Abstract

Chemical injuries have well-known sequelae: corneal opacity, chronic ocular surface disorders, anterior segment inflammation. We present a case of disc edema due to chemical injury that has been reported in only a handful of cases.
Our patient 5yr/M presented three hours after a button battery entered his right eye, with symptoms of right eye swelling, pain, redness, frothy discharge. Open globe was ruled out; 2-3L RL wash given. The button battery had leaked far back into the superior fornix, was then removed. On examination: Roper Hall Classification Grade II-III: corneal edema, macular corneal opacity, overlying large non-healing epithelial defect, 3 clock hours limbal ischemia. No abnormality detected on fundus examination. Day 5: Amniotic membrane transplantation done. Day 23: epithelial defect healed, corneal edema settled, fundus examination revealed disc edema. IV Methylprednisolone, oral steroids tapered appropriately led to improvement in vision with reduction in disc edema.
