- 🔬Pathophysiology
- Sudden blockage of aqueous outflow at the iridocorneal angle → acute rise in intraocular pressure.
- 🩺Signs & Symptoms
- Severe eye pain, red eye, fixed mid-dilated pupil, halos around lights, headache, N/V, decreased vision.
- 🎯Gold Standard Diagnosis
- Gonioscopy confirms a closed angle (definitive); tonometry shows markedly ↑ IOP.
- 💊First-line Treatment
- Emergent IOP lowering (acetazolamide, topical beta-blocker, pilocarpine) → definitive laser iridotomy.
