Parapapillary chorioretinal atrophy and decreased retinal vessel diameter occur in glaucomatous eyes. To evaluate the frequency and degree of these signs in nonglaucomatous optic neuropathy, the authors evaluated morphometrically and compared 47 patients with nonglaucomatous optic nerve atrophy from extraocular causes with 292 patients with primary open-angle glaucoma and 179 normal subjects. E...

purpose: to evaluate the visual outcomes and complications of low power transpupillary thermotherapy (ttt) in patients with neovascular age-related macular degeneration (amd). methods: the study included 20 eyes of 17 patients. diagnosis of exudative amd was established on the basis of fundus examination and fluorescein angiography (fa). ttt was performed using a diode laser at 810 nm wavelengt...

A 26-year-old-man who had suffered a severe electrical injury 3 years previously presented with blurred vision in his left eye caused by a posterior subcapsular cataract with nuclear sclerotic changes and peripapillary chorioretinal scarring. The pattern of retinal atrophy surrounding the optic nerve suggests a possible path of electrical current to the eye and demonstrates the selective tissue...

Choroideremia is a rare X-linked disorder causing progressive chorioretinal atrophy. Affected patients develop night blindness with progressive peripheral vision loss and eventual blindness. Herein, we report two Korean families with choroideremia. Multimodal imaging studies showed that the probands had progressive loss of visual field with characteristic chorioretinal atrophy, while electroret...

We report a case of geographic or mosaic pattern yellowish opaque foci in the left eye of a 36-year-old woman who suffered from severe pre-eclampsia. Though the geographic lesions resulted in chorioretinal atrophy, the mosaic lesion led to no significant atrophy. These two findings were both diagnosed as manifestations of choroidal ischaemia, the former due to choroidal artery occlusion, the la...

Three cases of Japanese patients with gyrate atrophy of the choroid and retina with hyperornithinaemia were studied clinically and biochemically. The types of disease differed in responsiveness to vitamin B6. In-vivo responsiveness to vitamin B6 was correlated with in-vitro data. It is suggested that the in-vitro examination of the influence of pyridoxal phosphate on ornithine ketoacid transami...

The epidemiology and natural history of onchocerciasis and its ocular complications in rain forest areas are poorly understood. The present study was conducted on a rubber plantation in a hyperendemic area in the rain forest of Liberia, West Africa, where 800 persons were examined. The prevalence of infection was 84% overall 29% had intraocular microfilariae, and 2.4% were blind in one or both ...
