The high-pressure bleb

Abstract

A 45-year-old male presented with a slowly progressive, painless swelling in his right eye for the past 6 months. He had undergone an open globe injury repair 10 years back and an eventful cataract surgery 5 years back. The presenting visual acuity in the affected eye was perception of light with inaccurate projection of rays. The intraocular pressure was 44 mm Hg with advanced glaucomatous cupping. The swelling was identified to be a communicating sub-tenon cyst secondary to scleral wound dehiscence from secondary angle closure glaucoma. Wound re-suturing, cyst excision and diode laser cyclophotocoagulation was performed in a single sitting, with explained poor visual prognosis.
