Sutureless Revision of Overhanging Filtering Blebs

Phacotrabeculectomy: Assessment of outcomes and surgical improvements

“…Although meticulous hemostasis was achieved on the episcleral area in our patients, a careful recheck of the episclera for leaking vessels before closing the conjunctival wound might The term bleb dysesthesia was recently introduced in the literature to describe bleb-related symptoms including pain, burning, foreign-body sensation, tearing, or ocular discomfort in eyes with filtering blebs; the symptoms were mostly the result of large or overhanging blebs. [21][22][23] The increased incidence of this late consequence of a filtering procedure is probably associated with the use of antimetabolites, mainly MMC. In a recent study, Anis et al 22 report that of the 15 eyes that developed bleb dysesthesia after trabeculectomy, 14 (93%) had MMC or 5-FU use.…”

In a prospective cross-sectional study, Budenz et al 23 found a higher dysesthesia score in eyes with the use of MMC than in eyes without MMC.…”

“…1,2 Use of a fornix-based conjunctival flap and application of MMC over a larger area could help achieve a diffuse bleb that is less likely to result in bleb dysesthesia. 22,23 The purpose of this study was to assess the outcomes of the current surgical approach, combined multiple variations as a whole, and the progress of the technique. The study was limited by the constraints of a retrospective nature and an uncontrolled comparison of separate series.…”

Corneal complications of glaucoma surgery

“…The visual acuity can be affected by blebinduced astigmatism [32,33,34 ]. Surgical management involves blunt dissection of the overhanging bleb from the cornea followed by limbal excision, whereas the dissecting bleb often requires removal and refashioning of the whole bleb.…”

Surgical outcomes of intermittent exotropia associated with concomitant hypertropia including simulated superior oblique palsy after horizontal muscles surgery only' by YA Cho and S-H Kim

“…Noninvasive approaches to examine bleb include ultrasound biomicroscopy and AS-OCT. 1,2 In our case, multiloculated bleb structure of dissecting portion apart from the main cystic bleb was confirmed by preoperative AS-OCT imaging and histological study. Previous reports of overhanging bleb [3][4][5] stated that leaking was not a common complication even without the safety measure or suture. No leakage of aqueous humour or fast healing might be due to multicystic structures of the overhanging bleb in which the exchange of aqueous humour is suppressed.…”
