Senile macular changes in the black African.
One thousand black African and 380 white Caucasian patients over the age of 50 were examined for evidence of age-related macular changes, namely, drusen, pigment epithelial atrophy, and disciform macular degeneration. Drusen and pigment epithelial changes were found to occur twice as commonly in Caucasians as in Africans; there was a much greater difference in the prevalence of disciform macula...
متن کاملOrganised macular plaques in exudative diabetic maculopathy.
Plaques of hard exudate measuring 0-5 to 10 disc diameters, which occurred in 5 eyes of 4 patients with diabetic maculopathy, showed complete organisation in 8 to 18 months with the formation of scars measuring 0-2 to 0 5 disc diameters. The visual acuity was related to the size and situation of the scar within the fovea, and, when the foveola was involved by plaque formation, visual reduction ...
متن کاملMacular CMV retinitis: a case report.
PURPOSE Cytomegalovirus (CMV) retinitis is the most common ocular opportunistic infection associated with AIDS. It usually affects the peripheral retina, sparing the macula. We describe an atypical CMV retinitis exclusively confined to the macula. METHODS A 43-year-old man with the diagnosis of AIDS developed a white retinal lesion confined to the macula of the right eye. Two weeks later, a m...
متن کاملFoveo-macular retinitis, solar retinopathy, and trauma.
Three patients are described with foveal lesions resembling minute holes following trauma. The similarity of the lesions to foveomacular retinitis and solar retinopathy suggests that all these conditions produce a similar, localised neuroretinal lesion with sparing of the pigment epithelium. Loss of the photoreceptors at the fovea would be expected to produce a lesion resembling a small retinal...
متن کاملSimultaneous Presence of Macular Corneal Dystrophy and Retinitis Pigmentosa in Three Members of a Family
Macular corneal dystrophy (MCD) is an autosomal recessive hereditary disease. In most cases, various mutations in carbohydrate sulfotransferase 6 (CHST6) gene are the main cause of MCD. These mutations lead to a defect in keratan sulfate synthesis. Retinitis pigmentosa (RP) is another eye disorder with nyctalopia as its common symptom. It has been shown that more than 65 genes have been implica...
