Background:
Hypotony secondary to overfiltration is a recognized complication following trabeculectomy. Persistent hypotony requires intervention .
Purpose:
We describe a modified version of placing conjunctival compression sutures directly over the scleral flap.
Synopsis:
A 70-year-old male patient diagnosed with primary open angle glaucoma in both eyes underwent combined surgery in the right eye. On the tenth post-operative day, the patient presented with severe hypotony with 360ª choroidal detachment. He was treated with corticosteroids and cycloplegics but developed hypotony maculopathy on the subsequent follow-up. Hence, he was further managed surgically by trans-conjunctival flap sutures to which he responded favorably with resolution of choroidal detachment and improvement in intraocular pressure and visual acuity.
Highlights:
Transconjunctival suturing of the scleral flap is an effective and minimally invasive treatment to prevent visual loss from hypotony maculopathy for an overfiltering bleb following trabeculectomy.
