Post Trabeculectomy Visual Loss: Is it Wipe-Out?

Abstract

Glaucoma filtration surgery in advanced glaucoma poses a significant challenge as it is associated with the rare risk of visual loss which is known as 'wipe-out' phenomenon. Our case had severe visual loss after trabeculectomy with cataract extraction for advanced primary angle closure glaucoma, which gradually recovered partially. Advanced visual field defect, high IOP in preoperative and immediate postoperative period, pallor of the neuro retinal rim pallor, and peribulbar anaesthesia were the plausible factors in our patient. This case highlights the rare but important complication of 'wipe-out', its risk factors, and further preventive measures in advanced glaucoma.
