Delayed Suprachoroidal Hemorrhage After Ahmed Valve Implantation for Neovascular Glaucoma

Abstract

Purpose: To report the case of delayed suprachoroidal hemorrhage after Ahmed valve implantation in a neovascular glaucoma (NVG) patient. Case summary: A 74-years-old male visited the hospital with ocular pain in the left eye. He had a history of vitrectomy and Intraocular lens (IOL) scleral fixation due to trauma in the left eye. NVG was diagnosed and Ahmed valve was implanted in his left eye. Three days later, hypotony occurred with all quadrant choroidal detachment. Next day, raised intraocular pressure (IOP) was checked and anterior chamber was flat on slit lamp examination. Vitreous hemorrhage and suprachoroidal hemorrhage were suspected. We performed anterior chamber formation with viscoelastics. The anterior chamber became deeper and hemorrhage gradually decreased. A month later, the patient visited us with severe ocular pain. Raised IOP and shallow anterior chamber due to moderate hyphema and anteriorly placed IOL were found. Retinal detachment was suspected on B-scan. Vitrectomy, IOL removal, silicone oil insertion, and Ahmed valve removal were performed. Conclusions: We report we experienced one patient of delayed suprachoroidal hemorrhage after Ahmed valve implantation and he had poor prognosis.
