Trabeculectomy with an implantable biodegradable collagen matrix (Ologen) for the management of glaucoma associated with cavernous sinus arteriovenous fistula

Isha Gulati Grover, Sirisha Senthil, Garudadri Chandrasekhar


A 58-year-old gentleman presented with open angle glaucoma secondary in the right eye secondary to a cavernous sinus arteriovenous fistula.  Since the intraocular pressure control was refractory to medical management, an augmented filtration surgery was planned.  Trabeculectomy in eyes with raised episcleral venous pressure is associated with a substantially greater risk of intraoperative or post-operative choroidal effusion and suprachoroidal haemorrhage.  This patient was successfully managed by performing trabeculectomy with an implantable biodegradable collagen, type 1 atelocollagen, matrix (Ologen), without any sight threatening complications.
