Posterior polymorphous dystrophy -
assistant
The correct answer is  It is a dominantly inherited dystrophy of endothelium and Descemet's membrane. It is characterised by lesions with variable appearance, such as vesicles, curvilinear lines or geographical opacities at the level of Descemet's membrane. The condition is very slowly progressive and thus usually asymptomatic. Corneal oedema sometimes may occur, requiring keratoplasty. Rarely it may be complicated by secondary glaucoma.Reference:Comprehensive ophthalmology,AK Khurana,4th edition,page no.119
