Abstract
Purpose. — To study the long term outcomes of surgical bleb reconstruction after glaucoma filtering surgery. Method. — A retrospective study of 46 eyes (43 patients, mean age 67.9 years ± 12.2, 30 women, 13 men) that underwent surgical bleb reconstruction for leaking bleb (56.53%), major bleb dysesthesia (17.39%), or extend bleb over cornea (26.08%). Bleb resection associated with the covering of filtering surgery site with conjunctival flap was performed 38.5 months (± 45.2) after initial filtering surgery. Results. — After a follow up of 24.3 months (± 17.9), intra ocular pressure was increased in 85.2% eyes: + 3.56 mmHg (± 4.3, p < 0,001), and a new hypotonic medication was needed in 26 %. Bleb dysesthesia was reduced in any case and none of the bleb was leaking any more. Conclusion. — Bleb excision with conjunctival advancement is a safe and effective procedure for the treatment of late bleb leak or major bleb dysesthesia. However in most cases, intra ocular pressure increase after reconstruction and new hypotensive medication may be required.
