Anaesthesia for glaucoma surgery

Acute rise in intra-ocular pressure may occur in predisposed eyes, and this can be sight-threatening. Acute angle closure glaucoma is discussed, along with a 3-step method to identify patients at risk. Patients who have recently had an intra-ocular gas bubble (with vitrectomy surgery) are at risk of blindness if they have a general anaesthesia with nitrous oxide, in the weeks before the bubble has dissolved.
