Management of Large Filtering Blebs with the Argon Laser

Effect of Diode Laser Application with G-Probe on Ocular Hypotony after Trabeculectomy with Mitomycin-C

“…Although the IOP increased in seven of eight eyes, the visual acuity increased Ն1 line in four (50%), remained stable in three (37.5%) and decreased 1 lines in one (12.5%). Unlike the mentioned reports, 21,27 in none of our patients leakage after laser application was seen. This may be due to application of laser around the thin and avascular blebs not over it.…”

Conditions for balance between lower normal pressure control and hypotony in mitomycin trabeculectomy

“…However, striving for low postoperative IOP by means of filtering surgery usually increases postoperative complications [3,41], and the use of mitomycin C is not an exception [10,15,22,31,39,45]. At present there are several means, including laser suture lysis, by which long-term bleb function can be influenced [14,23,27,30,36,42,44]. Therefore, recognition of patients in the early postoperative phase who will not achieve the desired late low IOP level, or those who will later develop long-term postoperative hypotony, is of clinical importance.…”

“Bleb Window”-Pexy for the Management of Symptomatic, Oversized Blebs

“…15,16 Cryotherapy 17 has been published in small case series in the literature. Argon, 11,18 yttrium aluminum garnet holmium, 19 yttrium aluminum garnet neodymium, 20,21 and, more recently, krypton green 22 laser treatments have also been reported as useful treatments in selected cases. Unfortunately, most cases that do not resolve spontaneously require definitive surgical intervention.…”

“…9,10 Although rare, severe complications have been documented, including bleb rupture, hypotony, and endophthalmitis. 11 Many techniques have been described for treating large, symptomatic filtering blebs. Chemical irritants such as silver nitrate 12 or trichloroacetic acid 13 and autologous blood injections 14 have not become popular owing to the high frequency of complications.…”
