CVL Risk After Severe Glaucoma Surgery

Sponsor: Gangnam Severance Hospital

View on ClinicalTrials.gov

Summary

This retrospective cohort study analyzes risk factors for central visual loss (CVL) after severe-stage glaucoma surgery. The primary hypothesis is that 1) visual prognosis is determined primarily by early postoperative intraocular pressure (IOP) stability rather than surgical choice, and 2) the nature of risk (hypotony vs hypertension) is modified by baseline visual reserve. We analyzed outcomes in 523 patients with severe-stage glaucoma who underwent trabeculectomy or Ahmed glaucoma valve (AGV) implantation, focusing on the dichotomous risk profile stratified by baseline visual acuity.
