Comparison of between Primary Open Angle glaucoma (POAG) and Ocular Hypertension (OHT) with special reference to mean Central Corneal Thickness (CCT)

Abstract— Glaucoma is the leading cause of irreversible blindness worldwide and is second only to cataract as the most common cause of blindness overall. Ocular Hypertension is the precursor of glaucoma. Central Corneal Thickness (CCT) is an important factor which is assessed to know the prognosis in management of the already diagnosed cases of glaucoma are assessed and Ocular Hypertension is pre glaucoma stage so this study was conducted to compare Central Corneal Thickness (CCT) Open-angle glaucoma (OAG) and Ocular Hypertension (OHT) cases. This study was conducted on 30 OAG and 30 OHT cases. It was observed that CCT is significantly lowered in OAG cases than OHT cases
