A 65-year-old male with pseudoexfoliation glaucoma, 4 days post-combined small incision cataract surgery with trabeculectomy, operated outside referred for shallow anterior chamber (AC). At presentation, Best-corrected visual acuity was 2/60 in LE and IOP was 2mm Hg. Slit lamp examination revealed diffuse bleb with flat anterior chamber both centrally & peripherally with a negative Siedels test in LE. Bscan showed 360 degree shallow choroidal detachments. The diagnosis of over filtering bleb was made, and flap resuturing was planned. Intraoperatively, large scleral buttonhole of 2 mm × 1 mm was seen exactly over the ostium [Figure 1]a with a poorly created thin scleral flap. A partial-thickness corneal patch graft of 5 mm × 4 mm size covering the buttonhole and flap area with a tight tamponade 10-0 nylon suture was placed [Figure 1]b. One month postoperatively, LE vision improved with well-formed AC [Figure 1]c. We report this to emphasize the significance of creating an adequate flap thickness as well as meticulous handling of flap while performing trabeculectomy to avoid flap-related complications postoperatively. The surgeon must defer proceeding with trabeculectomy if flap creation is not successful. Hypotony is a sight-threatening complication if not diagnosed at an early stage. Early intervention in our patient prevented irreversible vision loss due to hypotony.,,
