Management of Overfiltering and Leaking Blebs With Autologous Blood Injection

Sodium hyaluronate eye drops prevent late-onset bleb leakage after trabeculectomy with mitomycin C

“…[1][2][3] Bleb leaks may lead to hypotony maculopathy, choroidal detachment, blebitis and endophthalmitis. [2][3][4][5][6] Various methods of both medical and surgical management of late-onset bleb leaks exist, such as bandaged contact lenses, 7 autologous blood injections 8 and leaking bleb reconstruction with rotational or advancement conjunctival flap, 9 but none are without difficulty or have been universally successful; and in fact, treatments have often been associated with complications. Surgical bleb revision can cause immediate postoperative intraocular pressure elevations, persistent or recurrent leaks, conjunctiva shrinkage and retraction, wound dehiscence and additional filtering surgery.…”

Spontaneous hyphaema and intra-bleb subconjunctival haemorrhage in a patient with previous trabeculectomy

“…The authors demonstrate hyphaema as a recognised complication in this technique, which clearly demonstrates bidirectional flow across the scleral flap. 2,3 It would appear that our patient had retrograde flow as a result of the intrableb haemorrhage resulting in a clinically significant hyphaema. The prolonged bleeding time could well have been a contributing factor.…”
