PURPOSE: Age-related macular degeneration (ARMD) is clinically less common in India compared to the West. Therefore, clinicians are unfamiliar with histopathologic evidence of age-related macular changes in the Indian population. METHODS: Fifty consecutive human donor eyes removed for corneal grafting were studied for gross, microscopic and histochemical features of age-related changes in the macula in the Indian population. A horizontal block was cut from the globe including the optic disc, and the macula. Six sections, 6 microns thick, were cut from three levels in the macula at a distance of 140 microns. These were stained with haemotoxylin-eosin, periodic acid-Schiff, Mallory, Masson trichrome, alcian blue and von Kossa stains. The presence of basal laminar deposits, drusen and thickening and calcification of Bruch«SQ»s membrane in the macula were assessed at 400 x magnification using a modified version of Sark«SQ»s classification. RESULTS: Twenty-four donor eyes (48%) had some form of age-related macular change. These included basal laminar deposits, hard drusen, soft drusen, extensive retinal pigment epithelium atrophy of the macula, and disciform degeneration of macula. A combination of changes was often seen. Age-related changes were more common in the seventh and eighth decade. CONCLUSION: Our study shows that histological changes characteristic of the early stages of age-related macular degeneration are fairly common in the Indian population. However, advanced macular changes are significantly rare.
