Aims and background: Delayed suprachoroidal hemorrhage (DSCH) is a vision-threatening complication of intraocular surgeries with a higher prevalence in postglaucoma filtering surgeries. Through these case series of trabeculectomy complicated with DSCH, we aim to emphasize that correction of hypotony (inciting factor) is fundamental for complete resolution and prevention of recurrence. Case description: All three glaucoma patients underwent trabeculectomy surgery followed by DSCH on postoperative day 1. Drainage of DSCH using a 23 gauge trocar cannula within 48 hours of onset was performed along with exploration for the cause of hypotony. All three patients had satisfactory visual and anatomical outcomes. Conclusion: Early drainage using 23 gauge trocar cannulas gives good results in DSCH. The cause of hypotony must simultaneously be corrected during the drainage of DSCH. Preventive measures against hypotony should be taken while doing glaucoma filtering surgery. Clinical significance: Surgical exploration for the cause of hypotony must simultaneously be performed during drainage of DSCH. Primary preventive measures against hypotony and bleeding during glaucoma filtering surgeries, like the use of releasable sutures, viscoelastic in the anterior chamber, and discontinuation of anticoagulants, can be done. Early drainage using trocar cannulas gives satisfactory results in DSCH postglaucoma surgeries.
