Scratched cornea: Case report on incidental bilateral posterior polymorphous corneal dystrophy

Abstract

Posterior polymorphous corneal dystrophy (PPCD) is a dominantly inherited corneal endothelial disorder, typically considered bilateral and asymptomatic. We report a case of bilateral PPCD that presented as an incidental finding on routine ophthalmic examination. Related visual prognosis is discussed. A 27-year-old male presented for a routine ophthalmic examination. Visual acuity was recorded for both eyes. A detailed slit-lamp examination and anterior-segment optical coherence tomography (AS-OCT) was done. Best-corrected visual acuity was recorded as 6/6 for both eyes. Slit-lamp examination revealed band-shaped lesions in the inferior quadrant of bilateral corneas, at the junction of Descemet's membrane and corneal endothelium. AS-OCT revealed central corneal thickness as 556 and 544 µm for the right and left cornea, respectively, along with a hyper-reflective lesion at the level of corneal endothelium in the right eye.
