Secondary acute angle closure glaucoma after 25-gauge pars plana vitrectomy for a macular hole: a case report
Abstract
Posterior synechiae of the iris rarely cause secondary angle-closure glaucoma after pars plana vitrectomy, mainly reported in cases with high postoperative inflammation. The face-down position with gas tamponade can cause acute angle-closure glaucoma in phakic eyes owing to relative pupillary block. This report presents a rare case of pseudophakic eye with secondary acute angle-closure glaucoma after 25-gauge pars plana vitrectomy and long-term vitreous gas tamponade for a macular hole. A 61-year-old Japanese female patient presented with a chief complaint of right-sided visual impairment that had persisted for several months. Slit-lamp examination revealed deep anterior chamber and moderate nuclear sclerotic cataracts in both eyes. The axial length of the eye was 23.53 mm right eye and 24.05 mm left eye, and the fundus examination revealed a full-thickness macular hole (stage 3) in the right eye. The patient underwent simultaneous cataract surgery and pars plana vitrectomy with 7-mm diameter 3-piece monofocal intraocular lens implantation, internal limiting membrane peeling, and air tamponade. There were no complications during surgery. Due to non-closure of the macular hole, a second pars plana vitrectomy with internal limiting membrane inverted flap and SF6 gas tamponade was performed 13 days later. The patient maintained face-down position after both surgeries, and 6 days after the second surgery, intraocular pressure was elevated to 53 mmHg, and acute angle-closure…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
