A case of atypical band shaped keratopathy following intravitreal silicone oil injection in an aphakic eye

Abstract

Introduction: Silicon oil or polydimethylsiloxane fluid is used in complicated retinal detachment surgeries. Although it displays an array of side effects like progressive vascularisation, silicon granules in corneal stroma and corneal decompensation, the lesser known band shaped keratopathy is visually endangering and requires a new management protocol, as was seen in our case. Case: A 15-year-old girl with vision 6/60 in both eyes diagnosed with bilateral congenital cataract and retinal detachment underwent microincision vitrectomy, lensectomy along with perfluorocarbon and intravitreal silicon oil injection in the right eye under general anaesthesia. Calcific band shaped keratopathy was seen after 8 months which began as fine dust like deposits coalescing to form a horizontal band. A neutral, autoclaved solution of 0.5% EDTA chelating agent was spread over the cornea and deposits scraped under aseptic precautions after removing the superficial epithelium. A bandage contact lens was placed to enable healing.
