The prevalence of glaucoma in south india a population survey

, : The prevalence of glaucoma in south india a population survey. Bollettino di Oculistica 59(7-8): 435-446

Glaucoma screening was done in villages, in eye camps and in the out-patients department of the eye hospital in Hyderabad, South India. The overall glaucoma rate was 2.9%. Absolute glaucoma occurred in 0.6%, i.e., every 5 glaucomatous eye discovered was already blind from this disease. The population and doctors must become more glaucoma conscious. Villagers did not recognize glaucoma as a cause of preventable blindness. Screening was usually concentrated on cataracts. A strict correlation between the height of intra-ocular pressure and the size of the cupping of the optic disc was found. The excavation was from high intra-ocular pressure. Perimetry was not well tolerated among the screening procedures, since illiterate villagers will not co-operate in perimetry. Immature or mature cataract in 1/3 of the eyes presented complications. The strategy of screening was described. Due to the high proportion of absolute glaucomas tonometric screening was justified in this population where perimetry usually was not possible and cataract often prevented an exact estimation of the cup/disc-ratio.
