The advanced glaucoma intervention study (AGIS): 5. encapsulated bleb after initial trabeculectomy

Different modes of intraocular pressure reduction after three different nonfiltering surgeries and trabeculectomy

“…12 Thus, the size of the fi stula may not be important, while, other parameters such as bleb size, wall thickness, vascularity of the bleb wall, or the presence of the intrableb connective tissue may be parameters of importance. 13,14 This may be the reason why the postoperative IOP after Lectomy MMC is independent of the preoperative IOP. The outcome of nonfi ltering surgery, on the other hand, may be a function of the surgically modulated trabecular meshwork and collector channel, and the facility of the emisarial pathway via the scleral fl ap.…”

Long-term intraocular pressure control of eyes that developed encapsulated blebs following trabeculectomy

“…In all, 15 (83%) of 18 eyes responded to conservative management and three eyes (17%) required MMC-augmented excisional bleb On the other hand, other investigators suggested that EBs might be a risk factor for surgical failure. [20][21][22] Koller et al 20 retrospectively assessed the charts of 388 trabeculectomies performed between 1992 and 1994 and concluded that pseudophakia and EBs were the main risk factors for surgical failure. Gutierrez et al 21 prospectively studied 90 eyes that underwent trabeculectomy and were followed-up for at least 3 months.…”

Revision nach Filtrationschirurgie

“…Die Häufigkeit einer Tenonzyste wird in der Literatur mit 6-29 % angegeben [22]. Männliches Geschlecht und eine vorausgegangene Argonlasertrabekuloplastik stellen unter anderem Risikofaktoren dar.…”
