Bleb Reformation After Lateral Cantholysis in a Case of Prostaglandin-associated Periorbitopathy.

An 84-year-old male with uncontrolled intraocular pressure (IOP), despite maximum topical medications including prostaglandin F2α analog, had bilateral prostaglandin-associated periorbitopathy-related tight upper eyelids. One day after trabeculectomy of the left eyelid, IOP was 24 mm Hg, with a flat bleb. Daily ocular massage failed to maintain bleb filtration.

Postoperative Outcomes of PreserFlo MicroShunt in Patients with Exfoliation Glaucoma.

: This study aimed to evaluate the postoperative outcomes of the PreserFlo MicroShunt in Asian patients with exfoliation glaucoma. : We used the Kaplan-Meier method to analyze 29 eyes of 29 patients with exfoliation glaucoma (mean age: 80.7 ± 8.

Usefulness of Intraocular Pressure With the Ocular Response Analyzer to Predict Postoperative Hypotony Complications in Glaucoma.

Purpose: To investigate the usefulness of intraocular pressure (IOP) using the ocular response analyzer to predict the occurrence of hypotony complications following trabeculectomy or bleb needling revision with mitomycin C.

Methods: This study included 66 eyes of 66 patients who underwent trabeculectomy (58 eyes of 58 patients) or bleb needling (8 eyes of 8 patients) with mitomycin C. A significant predictor of hypotony complications was identified from (1) operation (trabeculectomy or bleb needling), (2) age, (3) sex, (4) disease type (primary open-angle glaucoma, primary angle closure glaucoma, or exfoliation glaucoma), (5) lens status (phakia or pseudophakia), (6) preoperative Goldmann applanation tonometry IOP, (7) preoperative central corneal thickness, (8) preoperative axial length, (9) preoperative anterior chamber depth, (10) preoperative corneal hysteresis, (11) preoperative corneal resistance factor, (12) preoperative corneal compensated IOP (IOPcc), and (13) minimum IOP (IOP value when hypotony complications occurred, otherwise the minimum IOP during 3 months from trabeculectomy or bleb needling) using multivariate logistic regression.

Comparing Corneal Biomechanic Changes between Solo Cataract Surgery and Microhook Ab Interno Trabeculotomy.

: This study aimed to examine the postoperative changes in the corneal biomechanical properties between solo cataract surgery and solo microhook ab interno trabeculotomy (LOT). : This retrospective case-control study included 37 eyes belonging to 26 patients who underwent solo cataract surgery and 37 eyes belonging to 31 patients who underwent solo µLOT. These two groups were matched according to their preoperative intraocular pressure (IOP), axial length (AL), and age.

Intraocular Pressure and Safety of Vitrectomy with Vitreous Gas Replacement using Low-concentration Nitrous Oxide Gas Anesthesia.

Purpose: This study aims to evaluate the efficacy and safety of vitrectomy with vitreous gas replacement using low-concentration nitrous oxide (N2O) gas anesthesia, focusing on intraocular pressure (IOP) changes, pain, anxiety, and safety outcomes.

Methods: This retrospective study analyzed 133 patients undergoing fluid-air exchange without use of such as SF6 or C3F8, at Saneikai Tsukazaki Hospital, Japan, from April 2019 to March 2022. Participants were divided into two groups: those receiving low-concentration nitrous oxide gas anesthesia (N2O group) and those receiving local anesthesia with room air inhalation (Air group).
