[Purtscher retinopathy in acute alcoholic pancreatitis. A case report].

Purtscher retinopathy is a retinal vasculopathy most commonly caused by head or chest trauma. The most frequent signs include white ischemic infarcts (cotton-wool spots) and retinal hemorrhages (intraretinal, preretinal, or flame). The signs of ischemic vasculopathy predominate in the interpapillomacular zone. We report a case of a 31-year-old woman with sudden bilateral loss of vision caused by Purtscher retinopathy in acute alcoholic pancreatitis.

Choroidal melanoma appearing as vitreous hemorrhage.

A 63-year-old woman had a spontaneous vitreous hemorrhage in her right eye that precluded adequate visualization of the posterior segment. Initial ultrasonic examination disclosed findings compatible with vitreous hemorrhage, hemorrhagic retinal detachment, and choroidal elevation. A second ultrasonic examination two months later showed findings compatible with choroidal melanoma, which was confirmed on histopathologic examination of the enucleated eye. Large vascular tumor channels, intratumor scar tissue, irregular tumor surface contour, and focal proliferation of retinal pigment epithelium confirmed the site of the hemorrhage, which had extended into the vitreous cavity.

Grading diabetic retinopathy from stereoscopic color fundus photographs--an extension of the modified Airlie House classification. ETDRS report number 10. Early Treatment Diabetic Retinopathy Study Research Group.

The modified Airlie House classification of diabetic retinopathy has been extended for use in the Early Treatment Diabetic Retinopathy Study (ETDRS). The revised classification provides additional steps in the grading scale for some characteristics, separates other characteristics previously combined, expands the section on macular edema, and adds several characteristics not previously graded. The classification is described and illustrated and its reproducibility between graders is assessed by calculating percentages of agreement and kappa statistics for duplicate gradings of baseline color nonsimultaneous stereoscopic fundus photographs. For retinal hemorrhages and/or microaneurysms, hard exudates, new vessels, fibrous proliferations, and macular edema, agreement was substantial (weighted kappa, 0.61 to 0.80). For soft exudates, intraretinal microvascular abnormalities, and venous beading, agreement was moderate (weighted kappa, 0.41 to 0.60). A double grading system, with adjudication of disagreements of two or more steps between duplicate gradings, led to some improvement in reproducibility for most characteristics.

Retinal periphlebitis after hormonal treatment.

Two cases, those of a man and a woman, developed retinal periphlebitis after hormonal treatment for infertility and contraceptives, respectively. Both had a unilateral severe decrease in visual acuity, and a central scotoma and defect in color vision were also present. The fundus had retinal edema, especially of the macula, a hyperemic disc with blurred margins, normal arteries, congested veins, and marked sheathing along the main veins, with retinal hemorrhages in the inferior half of the retina. Fluorescein angiography showed a delayed filling of the veins in the affected retina and late staining of these veins. Since there was severe visual impairment in each case, systemic adrenocorticosteroids were administered, and a rapid improvement in visual acuity occurred. In one patient, a trace Marcus-Gunn sign, a few small paracentral scotomas, and a defect in color vision were permanent sequelae.

[Clinical utility of long-term administration of trapidil (MDR-1865) in the treatment of diabetic retinopathy].

In order to investigate the usefulness of prolonged administration of trapidil in the treatment of diabetic retinopathy, a follow-up study was carried out after the end of a placebo-controlled, double-blind study of the drug in case of the trapidil-treated group who continued to be treated with 300 mg/day of trapidil (Rocornal) (TT group) and those of the placebo group who were not given any treatment after the end of the study (PP group). The TT group was significantly superior or tended to be superior to the PP group in improvement of hard exudates, retinal hemorrhages and soft exudates, and also in improvement of capillary microaneurysms on fluorescein fundus angiography. In the course of diabetic retinopathy by the global evaluation of findings in individual cases, the TT group was significantly superior or tended to be superior to the PP group. Photocoagulation was performed on 20 (28%) of 72 eyes of the PP group and 13 (19%) of 68 eyes of the TT group, with the mean interval to photocoagulation being 7.2 months for the PP group and 14.0 months for the TT group. There was a significant difference between the 2 groups in terms of the interval to photocoagulation. Randomized fundus photographic evaluation of the findings by the central evaluation committee showed that the TT group was significantly superior or tended to be superior in improving retinal hemorrhages, soft exudates and leakage of fluorescein dye, and was also significantly superior or tended to be superior in relation to the course of the retinopathy, which was consistent with the evaluation by the attending ophthalmologists.(ABSTRACT TRUNCATED AT 250 WORDS)

Severe papilledema identified 3 weeks after head injury.

A 62-year-old woman presented with rapidly developed visual disturbance without associated headache or nausea 3 weeks after head injury. Ophthalmologic examination revealed bilateral severe papilledema with retinal hemorrhage, and intracranial pressure (ICP) was 17.5 cmH2O estimated by lumbar puncture. Computed tomography and magnetic resonance (MR) imaging showed no evidence of increased ICP, except dilation of the subarachnoid space around the optic nerves with distortion of the nerves. Her visual acuity remarkably improved after steroid and glycerol treatment, and optic fundus examination revealed bilateral clear optic papillae without atrophic changes. Follow-up MR imaging demonstrated that the bilateral optic nerves had regained the normal appearance. These results indicate that the bilateral papilledema was caused by increased subarachnoid pressure around the bilateral optic nerves. We conclude that papilledema can occur with a mildly increased ICP and trapped subarachnoid cerebrospinal fluid around the optic nerves, and papilledema may progress after the ICP is normalized. Papilledema is a warning sign for increased ICP, associated with future visual loss from retinal hemorrhage. Therefore, repeated funduscopic investigation is necessary for the early diagnosis and treatment of papilledema.

Complications of acute symptomatic posterior vitreous detachment.

During a ten-year period, 172 eyes of 155 patients developed acute symptomatic posterior vitreous detachments. The study included only patients examined within three months of the onset of symptoms. The patients ranged in age from 22 to 82 years, with an average age of 60 years. Of the 172 eyes, 118 (69%) developed no retinal or vitreous complications. Retinal tears occurred in 14 eyes (8%) and vitreous or retinal hemorrhages occurred in 36 eyes (21%). Seventeen patients (11%) who had acute symptomatic posterior vitreous detachment in one eye later developed acute symptomatic posterior vitreous detachment in the fellow eye. The second posterior vitreous detachment developed within two years of the first one in 15 eyes (88%). In 13 patients (76%), the second eye responded in the same manner to the posterior vitreous detachment as had the first, that is, ten pairs of eyes had no further complications, two pairs had retinal or vitreous hemorrhages, and one pair had retinal breaks.

Ocular manifestations in Dengue fever.

PURPOSE: To report a case of Dengue fever resulting in permanent visual loss in both eyes due to retinal capillary occlusion. METHODS: Case report. RESULTS: Severe permanent visual loss occurred in a patient with Dengue fever. Dilated fundus exam showed vascular sheathing with associated retinal hemorrhages at the equator and cotton wool spots in the maculae of both eyes. Fluorescein angiography revealed areas of capillary nonperfusion at the equator and in the macula. The diagnosis of Dengue fever was confirmed by serology detecting IgM antibodies to the Dengue virus. CONCLUSION: Ocular abnormalities may be seen in patients with Dengue fever, therefore ophthalmoscopy should be performed in patients presenting with severe forms of the disease.

Ocular involvement in patients infected by the West Nile virus.

West Nile virus (WNV), a mosquito-borne RNA virus for which there is no treatment, began emerging as a threat to health in the United States in 1999. Since then, its frequency and apparent clinical severity have increased. Patients with severe disease may experience ocular complications that include pain, vitreous inflammation, nonrelapsing chorioretinitis, retinal vasculitis, chorioretinal scarring, optic neuritis, and retinal hemorrhages. Age appears to be a risk factor for the development of ocular symptoms. Most patients with ocular involvement report floaters or decreased vision. Many ocular inflammatory conditions with an associated underlying systemic cause often present with chorioretinitis. However, the characteristic distribution and linear array or scattered pattern of the chorioretinal lesions seen in WNV is distinctive. The foregoing notwithstanding, other multifocal choroidopathies must be considered including syphilis, ocular histoplasmosis, multifocal choroiditis, tuberculosis, and sarcoid. Although topical steroids were reported to resolve WNV-induced uveitis and its associated keratic precipitates, most cases resolved irrespective of treatment, and relapses were uncommon. It is important for the eye care professional to be alert to the possible presence of WNV, particularly in older patients who present with ocular symptoms during mosquito season. Thus, a thorough ocular evaluation should include a dilated fundus examination and, when indicated, fluorescein angiography should be performed in patients suspected of being infected with WNV.
