Tamoxifen retinopathy in a male patient.

PURPOSE: To report a case of tamoxifen retinopathy in a male patient. METHODS: Case report. A 68-year-old man, who had received a cumulative tamoxifen dose of 60 g over 33 months for unresectable hepatocellular carcinoma, was evaluated. RESULTS: A peculiar, bilateral, symmetric, inner retinal crystalline deposition associated with mild macular edema was discovered. No other ocular toxicity of tamoxifen was observed. CONCLUSION: To our knowledge, this is the first report of tamoxifen retinopathy in a male.

Endoscopic vitreoretinal surgery for complicated proliferative diabetic retinopathy.

PURPOSE: To evaluate the indication for endoscopic vitreoretinal surgery in proliferative diabetic retinopathy (PDR). METHODS: Chart review of consecutive cases of vitreoretinal surgery for PDR performed by one of the authors (Y.L.F.) over a 2-year period. RESULTS: Endoscopic vitreoretinal surgery was performed in 8 of 41 (19.5%) eyes. The surgical indications were small pupil (3), hyphema (3), pseudophakia with fibrotic posterior capsule (1), and pars plana neovascularization with anterior tractional retinal detachment (6). CONCLUSION: Endoscopic vitreoretinal surgery, by enhancing the visualization of the retroirideal space, is a useful technique in PDR with opaque ocular media and/or neovascularization of the pars plana and ciliary body.

Retinal choroidal anastomoses and occult choroidal neovascularization in age-related macular degeneration.

OBJECTIVE: This study was designed to identify the incidence of retinal choroidal anastomoses in patients with occult choroidal neovascularization (CNV) and focal hot spots on indocyanine green (ICG) angiography, to identify the clinical and angiographic features that would assist in their identification, and to determine if the presence of these anastomotic lesions affect the outcome of laser therapy. DESIGN: Combined prospective and retrospective cross-sectional study. PARTICIPANTS: One hundred fifty consecutive patients with newly diagnosed occult CNV secondary to exudative age-related macular degeneration and focal hot spots on ICG angiography were evaluated prospectively. In addition, a retrospective review was performed on 79 eyes previously reported to have undergone laser photocoagulation treatment with ICG guidance. METHODS AND TESTING: In all cases, stereo color and red-free photographs, and stereo fluorescein and digital ICG angiograms were obtained for evaluation. MAIN OUTCOME MEASURES: Images obtained by all four techniques were evaluated for the presence of a retinal choroidal anastomosis. Associated clinical and angiographic findings were noted. In the retrospective review, the success rate of laser treatment was correlated with the presence or absence of a retinal choroidal anastomosis. RESULTS: Of the 150 eyes evaluated prospectively, 31 (21%) were found to have a retinal choroidal anastomosis. Retinal choroidal anastomoses were found in 27% of patients with associated serous pigment epithelial detachment (PED), whereas 13% were found in those without an associated elevation of the retinal pigment epithelium. Seventy-one percent of eyes had multiple anastomotic connections. Ninety percent of eyes had at least one retinal vein involved in the anastomotic connection. Clinical evidence of preretinal and intraretinal hemorrhage and cystic edema coupled with angiographic evidence of intraretinal dye leakage were key features of retinal choroidal anastomoses. In the retrospective review, seven patients were found to have retinal choroidal anastomoses with associated serous PED and demonstrated a very low (14%) success rate for laser treatment. CONCLUSIONS: Retinal choroidal anastomoses can present as a primary manifestation of the exudative process in age-related macular degeneration. They may be seen in eyes with and without detachment of the retinal pigment epithelium. Specific clinical and angiographic features have been identified that can aid in the diagnosis of these vascular anomalies. Their presence represents a poor prognostic sign for successful ICG-guided laser treatment.

Polypoidal choroidal vasculopathy masquerading as central serous chorioretinopathy.

OBJECTIVE: To differentiate polypoidal choroidal vasculopathy (PCV) from central serous chorioretinopathy (CSC). DESIGN: A retrospective, observational case series. PARTICIPANTS: Thirteen patients originally diagnosed with CSC proved to have PCV after more extensive evaluation and follow-up. METHODS: A clinical and angiographic review of patients with manifestations of CSC, including macular detachment. MAIN OUTCOME MEASURES: Demographic data, funduscopic examination, and fluorescein and indocyanine green (ICG) angiographic findings. RESULTS: Thirteen patients initially suspected of having CSC were ultimately diagnosed as having PCV. These eyes had exudative macular detachments secondary to a small caliber, polypoidal choroidal vascular abnormality or so-called polypoidal choroidal neovascularization. The clinical manifestations in the fundus varied. They included multiple, variably sized serous pigment epithelial detachments, neurosensory retinal detachment, lipid deposition, patchy atrophy of the pigment epithelium and indistinct staining from decompensation of the posterior blood-retinal barrier on fluorescein angiography. In reality, the suspected PEDs proved to be polypoidal lesions of PCV when imaged with ICG angiography. CONCLUSIONS: The clinical diagnosis of CSC or PCV generally poses little challenge to the experienced retinal specialist. However, in CSC with persistent and/or recurrent exudation, a myriad of retinal pigment epithelial changes may evolve that make it difficult to differentiate these two entities. In such patients, ICG angiography is useful in differentiating CSC from PCV. An accurate clinical diagnosis is important since each of these entities, CSC and PCV, may differ in terms of their risk factors, natural course, and visual prognosis.

Visual loss from arterial steal in patients with maxillofacial arteriovenous malformation.

OBJECTIVE: To determine whether an arterial "steal" from the ophthalmic artery accounts for the ocular manifestations associated with maxillofacial arteriovenous malformation (AVM) outside the orbit. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Seven patients with maxillofacial AVM who had been previously treated, unsuccessfully, with proximal ligation of the supplying external carotid artery branches were evaluated clinically and by superselective cerebral angiography. No cases had intraorbital arteriovenous shunting or abnormal venous drainage to the orbit. INTERVENTION: Endovascular embolization. MAIN OUTCOME MEASURES: Signs and symptoms of ocular ischemia were correlated with findings on cerebral/orbital angiography. RESULTS: Four of seven patients had signs of ocular ischemia. By selective angiography, these four patients were found to have a significant ophthalmic artery supply to the AVM. In contrast, the three patients without signs of ocular ischemia had minimal or no ophthalmic artery supply to the AVM. CONCLUSIONS: When the ophthalmic arterial blood supply is recruited, ophthalmic artery "steal" phenomenon occurs in patients with maxillofacial AVMs that do not directly involve the orbit. This mechanism appears to be the cause of ocular ischemia. It is possible that this "steal" is precipitated or worsened by previous surgical proximal ligation of external carotid arterial branches that are potential collaterals with the ophthalmic artery but fail to occlude the arteriovenous (AV) shunts.

Polypoidal choroidal vasculopathy and neovascularized age-related macular degeneration.

OBJECTIVE: To determine the nature and frequency of polypoidal choroidal vasculopathy (PCV) in a series of patients suspected of having neovascularized age-related macular degeneration (AMD). METHODS: A prospective analysis of 167 consecutive, newly diagnosed patients aged 55 years or older with presumed neovascularized AMD was performed. All patients were examined with fundus biomicroscopy as well as fluorescein and indocyanine green angiography. RESULTS: Choroidal neovascularization secondary to AMD was diagnosed in 154 (92.2%) of 167 patients; 13 (7.8%) patients had PCV. The patients affected by PCV were younger than those with AMD (P = .01). Peripapillary choroidal neovascularization was seen in 3 (1.9%) of 154 patients with AMD and 3 (23.1%) of 13 patients with PCV (P = .006). Significant drusen were present in 63 (70%) of 90 fellow eyes with unilateral AMD compared with only 1 (16.7%) of 6 eyes with PCV (P = .02). Only 5 patients with AMD (3.2%) were nonwhite compared with 3 patients with PCV (23.1%) (P = .02). CONCLUSIONS: A measurable number of elderly patients with findings suggestive of neovascularized AMD and serosanguineous macular manifestations will instead have PCV. Polypoidal choroidal vasculopathy can occur in any sex or race, but is more commonly seen in the peripapillary area, without associated drusen, and in nonwhite patients. It is important to differentiate AMD from PCV because there are significant differences in the demographic risk profile, natural course, visual prognosis, and management of these patients.

Systemic findings associated with central serous chorioretinopathy.

PURPOSE: To determine systemic factors associated with central serous chorioretinopathy. METHODS: In a retrospective study, 230 consecutive patients with central serous chorioretinopathy examined in a referral setting were compared with a historical gender-matched and age-matched control group of 230 patients with ocular findings who were examined in the same referral setting. RESULTS: The median age of the patients was 49.8 years, and of the control subjects, 50.0 years. The male-female ratio for both groups was 2.7:1. Patients with central serous chorioretinopathy were more likely to use psychopharmacologic medications (odds ratio = 2.6; 95% confidence interval = 1.30 to 5.19; P = .0049) and corticosteroids (odds ratio = 3.17; 95% confidence interval = 1.30 to 7.70; P = .0067) and were more likely to have hypertension (odds ratio = 2.25; 95% confidence interval = 1.39 to 3.63; P = .0008) than were the control subjects. CONCLUSIONS: This study identified psychopharmacologic medication use, corticosteroid use, and hypertension as factors associated with central serous chorioretinopathy. These findings reinforce the concept that stress and adaptations to stress play a role in this disorder. The findings of possible associations between central serous chorioretinopathy and both hypertension and corticosteroid usage suggest that these modifiable factors may influence morbidity of central serous chorioretinopathy.

Radiation-associated choroidal neovasculopathy.

PURPOSE: To characterize a newly discovered choroidal vascular abnormality in patients who have received radiation therapy for subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration. DESIGN: Two-center cross-sectional study. PARTICIPANTS: In the United States, there were 95 patients who were treated with 10 or 12 Gy of external beam photons. In Belgium, 98 patients were treated with 20 Gy. These patients were examined retrospectively for the presence of a specific CNV abnormality. RESULTS: During the follow-up period, an unusual vascular growth pattern was identified in 12 patients (12.6%) of those treated in the United States and in 7 (7.1%) of those treated in Belgium. These patients developed round or oval vascular blebs along the outer border of their neovascular lesions. These blebs profusely leaked fluorescein dye and could be imaged best by indocyanine green angiography. Patients with these blebs appeared to have a marked propensity for loss of visual acuity. CONCLUSION: An unusual pattern of new vessel growth occurred in 19 of the 193 patients with CNV treated with radiation. This new entity, termed radiation-associated choroidal neovasculopathy, is a recognizable disorder that appears to have a particularly poor prognosis.

External beam radiation therapy for choroidal neovascularization.

OBJECTIVE: This study aimed to determine the effect of external beam radiation therapy on choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). DESIGN: The study design was a nonrandomized clinical trial with an historic control group. PARTICIPANTS: A total of 91 patients were treated with external beam radiation. These patients were compared retrospectively to the 119 patients in a control group. INTERVENTION: Patients with subfoveal CNV who did not meet the criteria for laser treatment defined by published reports from the Macular Photocoagulation Study Group or who did not want laser treatment were considered for radiation therapy in a nonrandomized, prospective clinical trial. Additional entry criteria for this prospective study included visual acuity better than or equal to 20/320 on the Early Treatment Diabetic Retinopathy Study chart and a lesion size less than 12 disc areas. The patients were treated with 5 fractions of 200 cGy 6 MV external beam photons. MAIN OUTCOME MEASURES: The visual acuity measured at baseline was compared to the visual acuity after 1 year of follow-up. RESULTS: The mean baseline visual acuity of the 91 patients entered into the Radiation Study was 20/80. After 1 year, 83 patients (91.2%) completed follow-up, and their mean visual acuity dropped to 20/200. By comparison, the mean baseline visual acuity of the control patients also was 20/80, and after 1 year, the control subjects had a mean visual acuity of 20/125. At 1 year of follow-up, 49.4% of patients treated with radiation and 38.1% of the control subjects lost 3 or more lines of visual acuity (P = 0.16). CONCLUSIONS: This study found that external beam radiation using 1000 cGy in 5 fractions, a dose similar to that used in previous studies, was not effective in the treatment of CNV secondary to AMD. These results suggest that patients should not be treated with this dose of external beam radiation for CNV secondary to AMD.

Indocyanine-green videoangiography of drusen as a possible predictive indicator of exudative maculopathy.

OBJECTIVE: Recent studies have shown that indocyanine-green videoangiography (ICG-V) is useful to image occult choroidal neovascularization. The authors studied the ICG-V findings in fellow drusen eyes of patients with unilateral exudative age-related macular degeneration (AMD). The authors also studied the occurrence of exudative changes to determine whether ICG-V is useful in predicting future exudative changes in these eyes with only drusen. DESIGN: Cohort study. PARTICIPANTS: The authors studied 432 consecutive patients diagnosed with unilateral exudative AMD in whom the fellow eye had only drusen by clinical fundus examination and fluorescein angiography. All of these eyes had ICG-V performed. Follow-up data were obtained in all eyes with abnormal indocyanine-green (ICG) angiograms and randomly sampled ICG angiograms of normal eyes. MAIN OUTCOME MEASURES: The initial ICG findings were classified as showing normal or abnormal hyperfluorescence. Abnormal hyperfluorescence eyes were subdivided into focal spots (focal areas of hyperfluorescence < 1 disc area in size) and plaques (areas of hyperfluorescence > 1 disc area). The development of exudative changes in eyes with normal and abnormal hyperfluorescence was compared. RESULTS: Of the 432 fellow eyes, 386 (89%) eyes with drusen had a normal ICG-V study, whereas 46 (10 focal spots and 36 plaques) (11%) eyes had an abnormal ICG-V. Exudative changes occurred in 6 (10%) of 58 normal ICG eyes and 9 (24%) of 38 eyes with abnormal ICG findings during a mean follow-up period of 21.7 months. The difference between drusen eyes with normal ICG angiograms and those with plaques on ICG-V regarding future exudative changes (10% vs. 27%, respectively) was statistically significant (P = 0.038). CONCLUSIONS: Abnormal ICG findings were found in 11% of eyes with clinically and fluorescein angiographically nonsuspicious drusen. The subgroup of patients with plaques on ICG-V had a higher chance of having exudative changes develop. Indocyanine-green videoangiography may be a predictive indicator of future exudative changes in eyes with drusen. A much larger prospective study seems justified.

Wide-angle indocyanine green angiography.

BACKGROUND: Evaluation of the vasculature and blood flow in the fundus is limited by the small field of view of conventional fundus cameras. We sought to develop an easy method to image wide areas of the fundus. METHODS: Wide-angle contact fundus lenses with antireflective coatings in the infrared range were placed on the eye and indocyanine green angiography was done on the fundus through the contact lenses. More than 50 patients with varying fundus pathology have been examined. RESULTS: The angular field of view using this method can reach 160 degrees. Obtaining angiograms where the field of view extended anterior to the ora serrata was simplified, and studying the choroidal vasculature in detail was possible. In addition, imaging of entities such as peripheral choroidal neovascularization and choroidal tumors was enhanced with the present technique as compared with conventional techniques. CONCLUSIONS: Angiography through wide-angle fundus lenses is an easy and inexpensive method of visualizing large areas of the fundus. This technique may help improve our ability to image the angioarchitecture, hemodynamics, and pathologic changes in the retina and choroid.

Indocyanine green angiography of multifocal choroiditis.

PURPOSE: The purpose of the study is to determine indocyanine green (ICG) angiographic characteristics of patients with multifocal choroiditis (MC) and to identify features that may assist in the differentiation of MC from other ocular inflammatory diseases. METHODS: After complete ophthalmologic examination, fluorescein angiography and ICG angiography were performed in a series of 14 patients with MC. The ICG findings were then correlated with the clinical and fluorescein angiographic appearance of these patients to determine specific characteristics and distinguishing features of the entity. These findings then were compared with those of angiographic patterns observed in patients with ocular histoplasmosis syndrome to determine whether differentiating features could be identified. RESULTS: Fourteen (50%) of the 28 eyes were found to have large hypofluorescent spots in the posterior pole on ICG angiography, which, in most cases, did not correspond to clinically or fluorescein angiographically detectable lesions. Seventeen (61%) had smaller hypofluorescent lesions (approximately 50 pm in size) in the posterior pole on the ICG study. In seven eyes exhibiting enlarged blind spots on visual field testing, ICG angiography showed confluent hypofluorescence surrounding the optic nerve. The ICG angiogram was found useful in evaluating the natural course in two patients with MC as well as a response to oral prednisone therapy in four others. The ICG angiographic findings differed from those seen in patients with ocular histoplasmosis. CONCLUSIONS: Indocyanine green angiography can provide information that is not detectable by clinical or fluorescein angiographic examination in patients with MC. This information may prove useful in differentiating this condition from the ocular histoplasmosis syndrome, provide a better understanding of the natural course and progression of the disease, and provide a potential adjunct in the clinical evaluation of patients undergoing therapeutic regimens for active inflammatory lesions.

Indocyanine green-guided laser photocoagulation of focal spots at the edge of plaques of choroidal neovascularization.

OBJECTIVE: To determine whether indocyanine green-guided laser photocoagulation of focal spots at the edge of plaques of neovascularization is beneficial for patients with untreatable occult choroidal neovascularization by fluorescein imaging. PATIENTS: A pilot series of 23 eyes were identified that had untreatable occult choroidal neovascularization secondary to age-related macular degeneration with focal spots at the edge of a plaque of neovascularization on the indocyanine green study. After informed consent was obtained, indocyanine green-guided laser photocoagulation was applied solely to the focal spot at the edge of the plaque. RESULTS: Anatomical success with resolution of the exudative findings was noted in 15 (79%) of 19 eyes at 6 months, 13 (68%) of 19 eyes at 12 months, and six (37.5%) of 16 eyes at 24 months. The median follow-up period was 18 months (range, 3 to 44 months). Visual acuity was stabilized or improved in nine (69%) of 13 successfully treated eyes at 1 year. Of the successfully treated cases at 1 year, nine (69%) of 13 had a final visual acuity of 20/100 or better. CONCLUSIONS: Our preliminary study of indocyanine green-guided laser photocoagulation of focal spots at the edge of plaques of neovascularization suggests that this technique may improve the visual prognosis of these patients with presently untreatable disease. A prospective, randomized, controlled clinical trial is warranted to evaluate this treatment approach.

Central serous chorioretinopathy in younger and older adults.

PURPOSE: The purpose of the study is to investigate the demographic characteristics and clinical findings of central serous chorioretinopathy (CSC). METHODS: This study examined a consecutive series of 130 patients with CSC seen over an 18-month period. RESULTS: The mean age of the patients when examined was 51 years, and the male-to-female ratio was 2.6:1.0. A total of 62 patients were older than 50 years of age when first examined. Although the patients shared some clinical and angiographic similarities, the older patients had a lower mean visual acuity and were more likely to have diffuse retinal pigment epitheliopathy, bilateral involvement, and secondary choroidal neovascularization than were the younger patients. With ophthalmoscopic and angiographic examination results, it was possible to differentiate CSC in older adults from choroidal neovascularization. CONCLUSION: This study expands the clinical concept of CSC. The male-to-female ratio was much lower, and the range of ages of the patients was much greater than in previous studies. Disease manifestations in older adults differed somewhat from those seen in younger adults. In older patients, CSC can be distinguished from other exudative maculopathies, particularly that of choroidal neovascularization secondary to age-related macular degeneration.

Classification of choroidal neovascularization by digital indocyanine green videoangiography.

PURPOSE: The majority of patients with exudative maculopathy due to age-related macular degeneration present with poorly defined or occult choroidal neovascularization (CNV) that cannot be imaged adequately by fluorescein angiography. Digital indocyanine green (ICG) videoangiography is a new technique that allows enhanced imaging of these poorly defined or occult vessels. The authors studied 1000 consecutive cases of occult CNV using digital ICG angiography to describe the various types of neovascularization observed by this technique and to determine the frequency and natural history of the various lesions. MATERIALS AND METHODS: Digital ICG videoangiography was performed as described previously on 1000 consecutive eyes with occult CNV by fluorescein angiography. RESULTS: One thousand consecutive eyes with occult CNV by fluorescein angiography were imaged using digital ICG videoangiography. Three morphologic types of CNV were noted by ICG videoangiography, which included focal spots, plaques (well-defined or poorly defined), and combination lesions (in which both focal spots and plaques are noted). Combination lesions can be subdivided into marginal spots (focal spots at the edge of plaques of neovascularization), overlying spots (hot spots overlying plaques of neovascularization), or remote spots (a focal spot remote from a plaque of neovascularization). The relative frequency of these lesions was as follows: there were 283 cases (29%) of focal spots; 597 cases (61%) of plaques, consisting of 265 cases (27%) of well-defined plaques and 332 cases (34%) of poorly defined plaques; and 84 cases (8%) of combination lesions, consisting of 35 cases (3%) of marginal spots, 37 cases (4%) of overlying spots, and 12 cases (1%) of remote spots. In seven additional cases (1%), a mixture of the above lesions was noted. In 13 additional eyes (1%), no lesions were noted on the ICG angiogram. The studies of 16 eyes were unreadable or unobtainable. CONCLUSIONS: There are three types of CNV that can be observed by digital ICG videoangiography. Plaques are the most common type and have a poor natural history. Focal spots or hot spots are the next most frequently seen lesion and can potentially be treated by ICG-guided laser photocoagulation. Combination lesions, in which both focal spots and plaques are present, are rare. This study of 1000 consecutive cases of eyes with occult neovascularization that were imaged with digital ICG videoangiography serves to classify the various types of neovascularization observed by this technique. Digital ICG videoangiography is an important tool in better delineating eyes with occult CNV. Future studies are necessary to validate our findings.

Indocyanine green videoangiography of older patients with central serous chorioretinopathy.

PURPOSE: The authors studied the indocyanine green (ICG) videoangiography findings of central serous chorioretinopathy (CSC) in older adults. BACKGROUND: Central serous chorioretinopathy in older adults may be confused with the exudative forms of age-related macular degeneration (AMD) because the two entities may have similar ophthalmoscopic and fluorescein angiographic findings. Because of its enhanced ability to image the choroidal circulation, ICG videoangiography has been used to describe certain choroidal vascular abnormalities in young adults with CSC, as well as older patients with choroidal neovascularization (CNV). The ICG videoangiography findings in CSC in older adults is largely unknown. METHODS: The authors performed ICG videoangiography on 36 patients aged 50 years or older with CSC to characterize their findings. RESULTS: The ICG videoangiography findings of the patients were consistent, revealing choroidal vascular hyperpermeability manifested by areas of hyperfluorescence that were first seen in the midphase of the angiogram. In the later phases of the angiogram, there were dispersion of the hyperfluorescence and a distinctive silhouetting of the larger choroidal vessels. CONCLUSIONS: Older patients with CSC have a unique temporal and topographic pattern of hyperpermeability that can help establish the proper diagnosis.

Choroidal neovascularization in second eyes of patients with unilateral exudative age-related macular degeneration.

PURPOSE: To evaluate patients with unilateral occult choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) for the nature of the neovascularization which develops in the fellow eyes. METHODS: Patients with newly diagnosed unilateral occult CNV were followed prospectively for the development of CNV in the fellow eye. Patients were classified based on the type of occult CNV in the first eye: (1) those with associated serous pigment epithelial detachment (serous PED) and (2) those without. Demographic and clinical data, including the type of CNV in the second eyes, were compared. RESULTS: Choroidal neovascularization developed in 115 patients in the second eye. Fifty-six patients had occult CNV with a serous PED (also termed vascularized PED) in the first eye, and 59 patients had occult CNV without serous PED. The two groups did not differ significantly in the demographic and the clinical features evaluated. Well-delineated (or classic) CNV developed in the fellow eye of one patient in each group. Of the remaining 55 patients with vascularized PED in the first eye, the same type of occult CNV developed in 48 (87%) patients in the second eye. Of 58 (84%) patients in the second group, the same type of occult CNV developed in the second eye of 49 patients. This symmetric distribution of type of CNV between eyes is highly significant (P < 0.001). CONCLUSIONS: Eyes with occult CNV secondary to AMD can be classified by the presence or absence of an associated serous PED. Patients with unilateral occult CNV have a significant risk of occult CNV developing in the second eye, and the type of occult disease in the first eye is highly predictive of the type of neovascularized disease in the second eye. These findings are important with respect to natural history, and possibly to the treatment response and visual prognosis of patients with neovascularized AMD.
