Unusual sequelae of staphyloma following Ahmed glaucoma valve explantation and its management
Kolipaka PG; Krishnamurthy R; Bagga BBritish Medical Journal (Clinical Research Edition) Case Reports 2021; 14:
We report a case of a 7-year-old boy, who presented with plate exposure after Ahmed glaucoma valve (AGV) implantation in the eye with secondary glaucoma following penetrating trauma. He underwent AGV explantation with scleral patch graft and conjunctival limbal autograft and started on topical and oral antiglaucoma medication (AGM) for intraocular pressure (IOP) control. Two months later, he presented to us with high intraocular pressure and uveal tissue prolapse at the site of previous tube entry displacing the scleral and conjunctival grafts posteriorly. The defect was closed with corneal patch graft. Patient underwent limited transscleral cyclophotocoagulation and was maintained on topical AGM for IOP control. Our case highlights that explantation is a definitive management in such cases of plate exposure. Tube entry site is a potential weak area and there is risk of uveal prolapse through this area with high IOP. Corneal patch graft helps in successfully managing such defects involving the sclero-limbal region.
