Unilateral acute hydrops in a child with bilateral microcornea and iridofundal coloboma

A 15-year-old female child with history of bilateral poor vision since childhood presented with sudden onset pain, photophobia, and diminution of vision OD for 10 days. Visual acuity was hand motion OD and 1/60 OS. Slit lamp examination revealed microcornea OU with multiple intrastromal fluid clefts OD and an irregular cornea and iridofundal coloboma OS. A clinical diagnosis of acute corneal hydrops OD was made, and the child was subjected to intraoperative optical coherence tomography guided intrastromal fluid drainage with air tamponade. The corneal edema resolved completely within 2 weeks resuming visual acuity to 3/60 allowing laser delimitation of fundal coloboma OD.
