risk factors associated with sclerotomy leakage and Postoperative Hypotony after 23 gauge transconjunctival sutureless vitrectomy
Retina-the Journal of Retinal and Vitreous Diseases, 2009Co-Authors: Se Joon Woo, Kyu Hyung Park, Jeong Min Hwang, Jeong Hun Kim, Hum ChungAbstract:PURPOSE To investigate the incidence and risk factors of sclertomy leakage and Postoperative Hypotony after 23-gauge transconjunctival sutureless vitrectomy. METHODS This was a retrospective study including 322 eyes of 292 patients who underwent 23-gauge transconjunctival sutureless vitrectomy by a single surgeon with minimum follow-up period of 1 month. The incidence and risk factors of intraoperative suture placement for leaking sclerotomies and Postoperative Hypotony (vitrectomy (OR = 7.5), young age (<50 years) at operation (OR = 4.9), and vitreous base dissection (OR = 3.5). The incidences of Postoperative Hypotony were 11.3% at 2 hours, 6.5% at 5 hours, 3.8% at 1 day, and 0% at 1 week. Myopia and gas tamponade were associated with early Postoperative Hypotony. No complications developed related to sclerotomy leakage or Postoperative Hypotony. CONCLUSIONS The risk factors of intraoperative sclerotomy leakage requiring suture placement after 23-gauge transconjunctival sutureless vitrectomy are prior vitrectomy, a young age at operation, and vitreous base dissection. Caution should be exercised to ensure the detection of sclerotomy leakage and Hypotony in cases with these risk factors.

a new method for revision of encapsulated blebs after trabeculectomy combination of standard bleb needling with transconjunctival scleral flap sutures prevents early Postoperative Hypotony
PLOS ONE, 2016Co-Authors: Panagiotis Laspas, Philipp David Culmann, Franz Hermann Grus, Alicia Poplawksi, Norbert Pfeiffer, Verena Prokoschwilling, Esther Maria HoffmannAbstract:Purpose A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, Postoperative Hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early Postoperative Hypotony: bleb needling combined with transconjunctival sutures tightening the scleral flap directly. Methods The study included two groups of 23 patients with failing bleb following trabeculectomy: “Group 1” underwent simple needling revision of the filtering bleb and served as a control group, while “Group 2” received needling revision with additional transconjunctival scleral flap sutures, if intraoperatively the intraocular pressure was estimated to be very low. Intraocular pressure (IOP), Postoperative management and complications were analyzed over a follow-up period of 4 weeks Postoperatively. Results were compared using t-test or Mann-Whitney U-tests. Results Adverse effects occurred with a higher frequency after sole needling of the bleb (5 cases of choroidal effusion and 1 case of choroidal hemorrhage) than after the combined method with additional scleral sutures (1 case of choroidal effusion). The IOP on the first Postoperative day was significantly lower in group 1, with 9.43 ± 9.01 mm Hg vs. 16.43 ± 8.35 mm Hg in group 2 (P = 0.01). Ten patients with ocular Hypotony (IOD of 5 mmHg or lower) were found in group 1 and only two in group 2. One week and one month after surgery the intraocular pressure was similar in both groups (P>0.05). Conclusions This new needling technique with additional transconjunctival scleral flap sutures appears to reduce Postoperative Hypotony, and may thus protect from further complications, such as subchoroidal hemorrhage.

use of 25 sulfur hexafluoride gas mixture may minimize short term Postoperative Hypotony in sutureless 25 gauge pars plana vitrectomy surgery
Clinical Ophthalmology, 2013Co-Authors: Yoreh Barak, James W Heroman, Shlomit SchaalAbstract:Background The purpose of this study was to compare Postoperative intraocular pressures and percentage of vitreous cavity gas fill one day following 25-gauge pars plana vitrectomy with 20% versus 25% sulfur hexafluoride (SF6) gas fill.

two step oblique incision during 25 gauge vitrectomy reduces incidence of Postoperative Hypotony
Clinical and Experimental Ophthalmology, 2007Co-Authors: Makoto Inoue, Kei Shinoda, Hajime Shinoda, Ryosuke Kawamura, Kotaro Suzuki, Susumu IshidaAbstract:The efficacy of a two-step, oblique incision procedure during 25-gauge vitrectomy on Postoperative Hypotony was evaluated by a retrospective, case-control study. The transconjunctival incision during 25-gauge vitrectomy was made in two steps: penetration with a microvitreoretinal blade followed by a penetrater instrument of a blunt trocar. The two-step procedure was performed on 89 eyes and with the conventional incision on 68 eyes. The incidence of Hypotony (intraocular pressure <6 mmHg) on the first Postoperative day and after 1 week and 1 month was compared. Hypotony was found in two eyes (2%) with the two-step method and 12 eyes (18%) with the conventional incision on the first Postoperative day (P = 0.001, Fisher's exact probability test). The preoperative intraocular pressure was not significantly different in the two groups but was significantly higher in the two-step group than in the conventional method group on the first Postoperative day (P = 0.001, Wilcoxon rank test). Twenty-five-gauge vitrectomy with two-step oblique incisions will reduce the incidence of Postoperative Hypotony on the first Postoperative day.
