CTR-blocked angle increases IOP in chronic hypotony

Patients who underwent a novel surgical method to treat chronic ocular hypotony experienced increased IOP and visual acuity through a mean 27.7-month follow-up period, according to a study.
The retrospective case series describes a surgical method that consists of partially blocking the iridocorneal angle using a capsular tension ring to treat chronic ocular hypotony (COH). Researchers evaluated 13 patients with severe ocular hypotony after vitreoretinal or glaucoma filtration surgery. A capsular tension ring was placed in the iridocorneal angle by way of a corneal incision in each patient. The patients were followed for a minimum of 1 year and the main outcome measure was IOP.
Long-term control of COH was achieved and the IOP increased in each patient. Mean IOP statistically significantly increased, from a baseline of 3.77 mm Hg to 8.31 mm Hg after surgery (P = .001). Mean visual acuity improved significantly after surgery from 1.73 logMAR at baseline to 1.47 logMAR at follow-up (P = .017) ).
