Intravitreal bevacizumab (Avastin) as treatment for subfoveal choroidal neovascularisation secondary to pathological myopia.

OBJECTIVE: To evaluate the safety and efficacy of intravitreal bevacizumab (Avastin) as treatment for subfoveal choroidal neovascularisation (CNV) due to pathological myopia. METHODS: Consecutive series of primary or recurrent subfoveal CNV secondary to myopia treated with intravitreal bevacizumab 1.25 mg between August 2005 and January 2006 at the New England Eye Center, Boston, Massachusetts, USA, were reviewed retrospectively. Data from clinical examination, fundus photography, fluorescein angiography, optical coherence tomography and visual acuity were collected. RESULTS: There were 11 eyes of 9 patients. 5 of 11 eyes had been treated previously with photodynamic therapy. Pre-injection visual acuity measured 20/50 to 20/100 in 6 eyes and 20/200 or worse in 5 eyes. After a mean follow-up of 153 (range 35-224) days, post-injection visual acuity measured 20/20 to 20/40 in 7 eyes, 20/50 to 20/100 in 1 eye and 20/200 or worse in 3 eyes. Three eyes received two bevacizumab injections and eight eyes received one injection. Visual acuity improved by a mean of +3.5 (range -1 to +8 lines) lines, and 8 of 11 eyes achieved 20/50 or better at the last follow-up. Central foveal thickness improved from 340 (range 253-664) microm to 234 (range 142-308) microm, representing an average reduction of 103 (range +4 to -356) microm. No injection complications or drug-related side effects were observed. CONCLUSIONS: In this small series of eyes with limited follow-up, intravitreal bevacizumab seems to be safe and potentially efficacious in eyes with subfoveal CNV secondary to pathological myopia.

Ultrahigh-resolution optical coherence tomography of surgically closed macular holes.

OBJECTIVE: To evaluate retinal anatomy using ultrahigh-resolution optical coherence tomography (OCT) in eyes after successful surgical repair of full-thickness macular hole. METHODS: Twenty-two eyes of 22 patients were diagnosed as having macular hole, underwent pars plana vitrectomy, and had flat/closed macular anatomy after surgery, as confirmed with biomicroscopic and OCT examination findings. An ultrahigh-resolution-OCT system developed for retinal imaging, with the capability to achieve approximately 3-microm axial resolution, was used to evaluate retinal anatomy after hole repair. RESULTS: Despite successful closure of the macular hole, all 22 eyes had macular abnormalities on ultrahigh-resolution-OCT images after surgery. These abnormalities were separated into the following 5 categories: (1) outer foveal defects in 14 eyes (64%), (2) persistent foveal detachment in 4 (18%), (3) moderately reflective foveal lesions in 12 (55%), (4) epiretinal membranes in 14 (64%), and (5) nerve fiber layer defects in 3 (14%). CONCLUSIONS: With improved visualization of fine retinal architectural features, ultrahigh-resolution OCT can visualize persistent retinal abnormalities despite anatomically successful macular hole surgery. Outer foveal hyporeflective disruptions of the junction between the inner and outer segments of the photoreceptors likely represent areas of foveal photoreceptor degeneration. Moderately reflective lesions likely represent glial cell proliferation at the site of hole reapproximation. Thin epiretinal membranes do not seem to decrease visual acuity and may play a role in reestablishing foveal anatomy after surgery.

Redefining lamellar holes and the vitreomacular interface: an ultrahigh-resolution optical coherence tomography study.

OBJECTIVES: To define optical coherence tomographic (OCT) criteria for the diagnosis of a lamellar macular hole, and to increase understanding of lamellar hole pathogenesis by examining fine anatomic features using ultrahigh-resolution optical coherence tomography (UHR OCT). DESIGN: Retrospective observational case series. PARTICIPANTS: Nineteen eyes of 18 patients with lamellar holes were imaged with UHR OCT between 2002 and 2004. METHODS: A UHR OCT system was developed for use in the ophthalmology clinic. All 6 UHR OCT images for each eye imaged were examined. Lamellar holes were diagnosed based on a characteristic OCT appearance. Criteria for the OCT diagnosis of a lamellar hole were as follows: (1) irregular foveal contour; (2) break in the inner fovea; (3) intraretinal split; and (4) intact foveal photoreceptors. From 1205 eyes of 664 patients imaged with UHR OCT, and retrospectively reviewed, 19 eyes of 18 patients were diagnosed with a lamellar hole based on these criteria. All 19 eyes were also imaged with standard resolution OCT. Their charts were retrospectively reviewed. MAIN OUTCOME MEASURES: Standard and ultrahigh-resolution OCT images. RESULTS: On chart review, clinical diagnosis of a lamellar hole was made in only 7 of 19 eyes (37%). Twelve of 19 eyes (63%) had an epiretinal membrane (ERM) on clinical examination. Ten of 19 eyes (53%) had a posterior vitreous detachment. On UHR OCT, 17 of 19 eyes (89%) had ERMs. Eleven ERMs had an unusual thick appearance on UHR OCT. Due to poor visual acuity, 4 eyes underwent vitrectomy. Only 1 of 4 surgeries (25%) was visually and anatomically successful. Another eye improved visually, but a lamellar hole persisted. One eye progressed to a full-thickness macular hole preoperatively, which reopened after surgery. One eye developed a full-thickness hole postoperatively. CONCLUSIONS: The diagnosis of a lamellar hole can be made based on OCT criteria, which could be applied to both standard and ultrahigh-resolution OCT. The increased resolution of UHR OCT sheds light on the pathogenesis of the lamellar hole. Epiretinal membranes were visualized on UHR OCT in the majority of eyes. Many ERMs had an unusual thick appearance on UHR OCT, which may represent either trapped vitreous or posterior hyaloid, and may help stabilize retinal anatomy. Conversely, ERM contraction may play a role in lamellar hole formation. Vitrectomy surgery was anatomically and visually successful in only 1 of 4 patients, suggesting caution when performing vitrectomy on lamellar holes.

Ultrahigh-resolution optical coherence tomography in patients with decreased visual acuity after retinal detachment repair.

OBJECTIVE: To assess microstructural changes in the retina that may explain incomplete visual recovery after anatomically successful repair of rhegmatogenous retinal detachments (RD) using ultrahigh-resolution optical coherence tomography (UHR OCT). DESIGN: Retrospective observational case series. PARTICIPANTS: Seventeen patients with decreased visual acuity after RD repair. Twelve patients had macula-involving and 5 had macula-sparing RDs. METHODS: The UHR OCT prototype capable of approximately 3 mum axial resolution was developed for clinical use. The UHR OCT images through the center of the fovea in 17 patients with visual complaints after RD surgery were obtained. Patients were either postoperative patients from the New England Eye Center or tertiary referrals. Baseline visual acuity, preoperative lens status, location of retinal detachment, macular involvement, and postoperative visual acuity were recorded. MAIN OUTCOME MEASURES: The UHR OCT images after RD repair. RESULTS: The UHR OCT images were obtained 1 to 84 months (median, 5 months) postoperatively. The mean preoperative logarithm of the minimum angle of resolution (logMAR) visual acuity was 1.37 (Snellen equivalent, 20/390). The mean postoperative logMAR visual acuity was 0.48 (Snellen equivalent, 20/60). Anatomical abnormalities that were detected included distortion of the photoreceptor inner/outer segments (IS/OS) junction in 14 of 17 patients (82%), epiretinal membranes in 10 of 17 patients (59%), residual subretinal fluid in 3 of 17 patients (18%), and cystoid macular edema in 2 of 17 patients (12%). Of the 5 patients with preoperative macula-on detachments, 4 had distortion of the outer retina after RD repair. CONCLUSIONS: The higher resolution of UHR OCT facilitates imaging of the IS/OS junction. Therefore, UHR OCT is able to confirm prior histopathologic findings that damage to photoreceptor outer segments may occur as a consequence of retinal detachment. This may explain poor postoperative visual acuity in eyes with anatomically successful repair.

Comparison of ultrahigh- and standard-resolution optical coherence tomography for imaging macular hole pathology and repair.

PURPOSE: To compare ultrahigh-resolution optical coherence tomography (UHR-OCT) technology to a standard-resolution OCT instrument for the imaging of macular hole pathology and repair; to identify situations where UHR-OCT provides additional information on disease morphology, pathogenesis, and management; and to use UHR-OCT as a baseline for improving the interpretation of the standard-resolution images. DESIGN: Observational and interventional case series. PARTICIPANTS: Twenty-nine eyes of 24 patients clinically diagnosed with macular hole in at least one eye. METHODS: A UHR-OCT system has been developed and employed in a tertiary-care ophthalmology clinic. Using a femtosecond laser as the low-coherence light source, this new UHR-OCT system can achieve an unprecedented 3-mum axial resolution for retinal OCT imaging. Comparative imaging was performed with UHR-OCT and standard 10-mum resolution OCT in 29 eyes of 24 patients with various stages of macular holes. Imaging was also performed on a subset of the population before and after macular hole surgery. MAIN OUTCOME MEASURES: Ultrahigh- and standard-resolution cross-sectional OCT images of macular hole pathologies. RESULTS: Both UHR-OCT and standard-resolution OCT exhibited comparable performance in differentiating various stages of macular holes. The UHR-OCT provided improved imaging of finer intraretinal structures, such as the external limiting membrane and photoreceptor inner segment (IS) and outer segment (OS), and identification of the anatomy of successful surgical repair. The improved resolution of UHR-OCT enabled imaging of previously unidentified changes in photoreceptor morphology associated with macular hole pathology and postoperative repair. Visualization of the junction between the photoreceptor IS and OS was found to be an important indicator of photoreceptor integrity for both standard-resolution and UHR-OCT images. CONCLUSIONS: Ultrahigh-resolution optical coherence tomography improves the visualization of the macular hole architectural morphology. The increased resolution of UHR-OCT enables the visualization of photoreceptor morphology associated with macular holes. This promises to lead to a better understanding of the pathogenesis of macular holes, the causes of visual loss secondary to macular holes, the timing of surgical repair, and the evaluation of postsurgical outcome. Ultrahigh-resolution optical coherence tomography imaging of macular holes that correspond to known alterations in retinal morphology can be used to interpret retinal morphology in UHR-OCT images. Comparisons of UHR-OCT images with standard-resolution OCT images can establish a baseline for the better interpretation of clinical standard-resolution OCT images. The ability to visualize photoreceptors and their integrity or impairment is an indicator of macular hole progression and surgical outcome.

Photodynamic therapy of idiopathic and inflammatory choroidal neovascularization in young adults.

PURPOSE: To evaluate the treatment of subfoveal choroidal neovascularization (CNV) using photodynamic therapy (PDT) with verteporfin (Visudyne; Novartis, Duluth, GA) in young adults. DESIGN: Retrospective noncomparative interventional case series. PARTICIPANTS: Nineteen eyes of 17 patients with classic, subfoveal CNV treated with PDT using verteporfin, excluding eyes with CNV secondary to age-related macular degeneration, angioid streaks, and myopia. MAIN OUTCOME MEASURES: Snellen visual acuity before and after PDT. RESULTS: Nineteen eyes were followed an average of 12.8 months (range, 4-33 months) after PDT. Before treatment, visual acuity measured > or = 20/40 in 0 eyes (0.0%), < 20/40 to > 20/200 in 11 eyes (57.9%), and < or =20/200 in 8 eyes (42.1%). After treatment, visual acuity measured > or =20/40 in four eyes (21.1%), < 20/40 to > 20/200 in eight eyes (42.1%), and < or =20/200 in seven eyes (36.8%). Six eyes (31.6%) underwent retreatment, with only two eyes retreated twice. Four eyes underwent eventual surgical removal of the CNV after PDT. CONCLUSIONS: Photodynamic therapy seems to be useful in stabilizing and improving visual acuity in young adults with subfoveal CNV secondary to idiopathic and inflammatory etiologies.

Multifocal electroretinography response after laser photocoagulation of a subretinal nematode.

PURPOSE: To describe multifocal electroretinography findings before and after laser photocoagulation of a subretinal nematode in diffuse unilateral subacute neuroretinitis. METHOD: Observational case report. A 45-year-old woman with left eye inflammation, subretinal tracts superior and temporal to the fovea, and a subretinal coiled mobile parasite was treated with laser photocoagulation to destroy the nematode. Multifocal electroretinography was performed before and after laser photocoagulation. RESULTS: In the left eye, multifocal electroretinography before treatment showed decreased foveal response density and increased parafoveal and perifoveal waveform amplitudes. Two months after laser photocoagulation, multifocal electroretinography showed full recovery of normal findings and the visual acuity remained 20/20. CONCLUSION: Multifocal electroretinography appears to be useful in evaluating the retinal findings after photocoagulation of a parasite associated with diffuse unilateral subacute neuroretinitis.

Optical coherence tomography findings following photodynamic therapy of choroidal neovascularization.

PURPOSE: To develop an optical coherence tomography (OCT) classification system that monitors the response of eyes treated with photodynamic therapy (PDT) with verteporfin for subfoveal choroidal neovascularization (CNV) from age-related macular degeneration (AMD). DESIGN: Retrospective interventional case series. METHODS: Ninety eyes (88 patients) with AMD and predominantly classic subfoveal CNV treated with PDT using verteporfin were identified by a laser log and retrospectively reviewed. Optical coherence tomography and fluorescein angiography (FA) were performed before treatment and at subsequent follow-up examinations in all eyes. Optical coherence tomography findings were evaluated and compared with corresponding FA. RESULTS: A five-stage OCT classification of eyes treated with PDT was created from the evaluation of 79 total eyes (77 patients). Stage I (two eyes) is recognized within the first week of treatment and demonstrates an acute inflammatory response with increased subretinal fluid. Stage II (28 eyes) represents the restoration of a near-normal fovea contour with diminished subretinal fluid occurring 1 to 4 weeks after treatment. Stage III (79 eyes) occurs between 4 to 12 weeks following treatment and is subdivided into two categories based on the amount of subretinal fibrosis and fluid present. Stage IIIa (15 eyes) contains a greater subretinal fluid to fibrosis ratio indicating an active CNV process. Lesions in stage IIIb (64 eyes) less actively leak and have more prominent fibrosis with minimal intraretinal fluid. Cystoid macular edema defines a stage IV lesion (11 eyes). In stage V lesions (19 eyes) the subretinal fluid resolves with thinning of the retina as well as fibrosis merging with the retinal pigment epithelial layer (RPE). CONCLUSION: Optical coherence tomography appears to be useful in monitoring the retinal changes that occur following PDT of CNV and may assist in understanding the changes observed on angiography.

Intravitreal triamcinolone for refractory diabetic macular edema.

PURPOSE: To determine if intravitreal injection of triamcinolone acetonide is safe and effective in treating diabetic macular edema unresponsive to prior laser photocoagulation. DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: Sixteen eyes with clinically significant diabetic macular edema (CSME) that failed to respond to at least two previous sessions of laser photocoagulation. METHODS: Eyes were diagnosed with CSME and treated with at least two sessions of laser photocoagulation according to Early Treatment Diabetic Retinopathy Study guidelines. At least 6 months after initial laser therapy, the response was measured by clinical examination and optical coherence tomography (OCT). Eyes with a residual central macular thickness of more than 300 microm (normal, 200 microm) and visual loss from baseline were offered intravitreal injection of 4 mg triamcinolone acetonide. The visual and anatomic responses were observed as well as complications related to the injection procedure and corticosteroid medication. MAIN OUTCOME MEASURES: Visual acuity and quantitative change in OCT macular thickening were assessed. Potential complications were monitored, including intraocular pressure response, cataract progression, retinal detachment, vitreous hemorrhage, and endophthalmitis. RESULTS: All patients completed 3 months of follow-up, and 8 of 16 patients (50%) completed 6 or more months of follow-up. Mean improvement in visual acuity measured 2.4, 2.4, and 1.3 Snellen lines at the 1-, 3-, and 6-month follow-up intervals, respectively. The central macular thickness as measured by OCT decreased by 55%, 57.5%, and 38%, respectively, over these same intervals from an initial pretreatment mean of 540.3 microm (+/-96.3 microm). Intraocular pressure exceeded 21 mmHg in 5, 3, and 1 eye(s), respectively, during these intervals. One eye exhibited cataract progression at 6 months. No other complications were noted over a mean follow-up of 6.2 months. Reinjection was performed in 3 of 8 eyes after 6 months because of recurrence of macular edema. CONCLUSIONS: Intravitreal triamcinolone is a promising therapeutic method for diabetic macular edema that fails to respond to conventional laser photocoagulation. Complications do not appear to be prohibitive. Further study is warranted to assess the long-term efficacy and safety, and the need for retreatment.

Photodynamic therapy of polypoidal choroidal vasculopathy.

Polypoidal choroidal vasculopathy is an abnormality of the choroidal vasculature characterized by aneurysmal-like budding of the vessels with exudation and recurrent serosanguinous detachments of the retinal pigment epithelium. Treatment is limited to laser photocoagulation of leaking vessels, which is used when vision is decreased, or exudate and hemorrhage threaten or involve the fovea. This article describes a patient with polypoidal choroidal vasculopathy successfully treated with photodynamic therapy using verteporfin.

Vitrectomy for stage 1 macular holes identified by optical coherence tomography.

BACKGROUND AND OBJECTIVE: To describe a series of patients with decreased vision secondary to stage 1 macular hole confirmed by optical coherence tomography (OCT) that failed to spontaneously resolve with observation. To determine whether current surgical techniques can prevent progression to a full-thickness macular hole and lead to improved visual acuity. PATIENTS AND METHODS: Retrospective, comparative case series presenting patient demographics, duration of symptoms, timing of surgery, preoperative and postoperative vision, and clinical outcome based on examination and OCT. RESULTS: Five eyes of five patients with stage 1 macular holes identified on OCT required surgical repair. All eyes showed anatomic closure and lack of progression to a full-thickness hole confirmed by OCT after one procedure. Mean preoperative visual acuity was 20/102 (range, 20/50 to 20/200) and mean postoperative visual acuity was 20/52 (range, 20/25 to 20/200). Average improvement for all five eyes was 3 Snellen lines, with four of the five (80%) improving 5 lines each. CONCLUSION: In symptomatic eyes with stage 1 macular holes that fail to spontaneously resolve with observation, vitrectomy with intraocular gas tamponade may prevent progression to a full-thickness hole and lead to improved visual acuity.
