·AIM: To present a case of Coats' disease in adult and to illustrate the retinal findings.·METHODS: A case report.·RESULTS: A 63 years old Malay man, a known case of diabetes mellitus, presented with one year history of painless and progressive reduced vision in the right eye. Right eye visual acuity was counting finger 2 feet while left eye best corrected visual acuity was 6/12. Right fundus showed presence of extensive subretinal exudates at the temporal part of the posterior pole involving the macular area and nasal to the optic disc. It was associated with multiple areas of abnormal blood vessels temporal to the macula with attenuated vessels. Fundus fluorescein angiography(FFA) showed presence of telangiectatic vessels at the area of subretinal exudates and leakage of fluorescein from the telangiectatic vessels. The left eye was normal. Based on clinical and FFA findings, he was diagnosed to have adult Coats' disease. The right eye was treated with argon laser photocoagulation. Six months post laser, his visual acuity remained at 6/120 and there was minimal regression of the disease seen in the retina. ·CONCLUSION: The clinical and angiographic findings are important in diagnosing retinal telangiectasia. Treatment by laser photocoagulation in area of leakages may be beneficial in preventing visual loss.

Introduction: There is limited knowledge on primary angle closure (PAC) in Malays. Understanding the clinical presentation and progression of PAC in Malays is important for prevention of blindness in Southeast Asia. Material and methods: A retrospective record review study was conducted on Malay patients seen in the eye clinic of two tertiary hospitals in Kelantan, Malaysia. Based on the available data, Malay patients re-diagnosed as primary angle closure suspect (PACS), primary angle closure (PAC), and primary angle closure glaucoma (PACG) based on the International Society Geographical Epidemiological classification. Clinical data was collected from initial presentation including the presence of acute primary angle closure until at least 5 years follow up. Progression was defined based on gonioscopic changes, vertical cup to disc ratio (VCDR), intraocular pressure (IOP) and Humphrey visual field (HVF) analysis. Progression and severity of PACG was defined based Hodapp-Parrish-Anderson classification on reliable HVF central 24-2 or 30-2 analysis. Results: A total of 100 patients (200 eyes) with at least 5 years follow up were included. 94 eyes (47%) presented with APAC. During initial presentation, 135 eyes (67.5%) were diagnosed with glaucomatous changes with 91 eyes already blind. After 5 years of follow up, 155 eyes (77.5%) progressed. There was 4 times risk of progression in eyes with PAC (p=0.071) and 16 times risk of progression in PACG (p=0.001). Absence of laser peripheral iridotomy was associated with 10 times the risk of progression. Conclusion: Angle closure is common in Malays. Majority presented with optic neuropathy at the initial presentation and progressed further. Preventive measures including promoting public awareness among Malay population is important to prevent blindness.
