# Large corneal epithelial detachment as a complication of wound burping to release aqueous humor for elevated intraocular pressure following cataract surgery

## TL;DR

Wound burping after cataract surgery can cause a large corneal epithelial detachment, which is a serious complication that should be avoided.

## Contribution

This case highlights a previously underreported complication of wound burping after cataract surgery.

## Key findings

- Wound burping caused an immediate large corneal epithelial bulla.
- The epithelial defect took 10 days to heal after the bulla sloughed off.
- Wound burping should be avoided once the corneal epithelium has healed over the surgical incision.

## Abstract

Wound burping is a technique used to treat intraocular pressure spikes in the immediate postoperative period after cataract surgery. A 55-year-old man with no history of glaucoma presented with painless blurring of vision in his left eye following cataract surgery 20 days earlier. Ophthalmic examination disclosed elevated intraocular pressure, mild conjunctival hyperemia, corneal microcystic epithelial edema, and mild anterior chamber reaction. In an attempt to lower the intraocular pressure quickly, the corneal wound was ‘burped’ at the slitlamp. Upon burping the wound, a large epithelial bulla formed instantly in the cornea. The patient’s blinking caused the corneal epithelial bulla to burst and collapse. Examination the next day disclosed the detached epithelium had sloughed off completely. The epithelial defect healed gradually over 10 days. Wound burping to release aqueous humor after the corneal epithelium has healed over the surgical incision can result in corneal epithelial detachment and should be avoided.
