Tenon patch graft for corneal fistula: a rare entity treated by a simple technique

A 50-year-old patient presented with dull aching pain with some discomfort in his right eye for the past 2 weeks. History revealed the patient had a past episode of infective keratitis managed medically in a local hospital. The last follow-up record suggested a diagnosis of healed keratitis with corneoiridic scar. On examination, the patient had visual acuity of hand movement and a corneoiridic scar of 7x7 mm with an inferotemporal translucent cystic area measuring 3x4 mm in size with underlying uveal tissue visible. Seidel test was found to be positive confirming leakage. For this, a tenon patch over the area of defect along with anterior chamber formation was done. On postoperative day 1, the graft was well attached and anterior chamber was formed with no leak on Seidel test. Intraocular pressure was 16 mm Hg.
