Overview
A sight-threatening emergency caused by sudden blockage of aqueous humour outflow at the trabecular meshwork by the peripheral iris. Leads to acute, severe elevation of intraocular pressure (typically > 40 mmHg). Immediate emergency ophthalmology/ED referral is required; IOP-lowering support may be needed while urgent transfer is being arranged within local scope and protocol. The fellow eye is at high risk.
