A 4.0; Carl Zeiss Meditec, Dublin, CA, USA) revealed macular edema (Fig. 1). Owing to failure of conservative treatment (intravenous normal saline supplement, abundant water intake, and frequent use of high potent steroid) for hypotony maculopathy, we injected sodium hyaluronate (Healon) into the anterior chamber 9 weeks after the operation, and repeated the same procedure 4 days later. After each injection, the IOP spiked up to 50 mmHg a few hours later, and intravenous infusion of mannitol was needed on postoperative day 1.
Suturing sclera flap at two sides (arrow) to preserve the bleb function by reopening the conjunctival flap.

Ten weeks after trabeculectomy with MMC, we decided to revise the bleb by suturing the scleral flap at two sides (Fig. 2).
One week after bleb revision, optical coherence tomography (OCT) of the right eye shows macular edema with folding decreased (central foveal thickness is 210 mum).

Optical coherence tomography also showed recovery from macular edema and restoration of the foveal contour (Figs. 3-5).
Three weeks after bleb revision, no macular edema of the right eye is noted (central foveal thickness is 202 mum).

Optical coherence tomography also showed recovery from macular edema and restoration of the foveal contour (Figs. 3-5).
Four months after bleb revision, no macular edema of the right eye is noted (central foveal thickness is 207 mum).
