'Progressive peripheral anterior synechiae in iridocorneoendothelial syndrome- a crawling disaster'.

Abstract

Purpose: Iridocorneal endothelial (ICE) syndrome is well known to cause refractory glaucoma in young adults. Commonly acclaimed mechanism for trabeculectomy failure in these cases include accelerated subconjunctival fibrosis, abnormal endothelial proliferation, and closure of ostium. In the following article, we present a case of Iridocorneal endothelial syndrome that presented with refractory glaucoma after trabeculectomy due to rapidly progressive peripheral anterior synechiae causing angle closure and corneal decompensation that mandated a tailored surgical approach of management. Methods: This is a descriptive case report based on electronic medical records, patient observation, surgical intervention, and follow-ups. Case description: A thirty-eight-year-old-male presented to us with signs suggestive of iridocorneal endothelial syndrome with gonioscopy revealing peripheral anterior synechiae (PAS) over four clock-hours temporally. Uncontrolled intraocular pressure (IOP) despite maximal medical therapy mandated augmented trabeculectomy with anti-fibrotics. The bleb failed within 3 weeks of trabeculectomy, with evidence of progressive crawling PAS causing endothelial decompensation and raised IOP. He underwent Ahmed glaucoma valve (AGV) implant surgery with viscosynechiolysis and sectoral iridectomy under antiviral cover. This helped control IOP and retain corneal clarity, with no recurrence of PAS in the affected area. Conclusion: Progressive peripheral synechiae in ICE syndrome can cause early bleb failure and refractory glaucoma. Careful viscosynechiolysis and sectoral iridectomy alongside a second implant surgery can help salvage visual functions and preserve corneal clarity while preventing further progression of PAS in these eyes.
