What sort of problem is acute angle closure glaucoma?

Serious: Angle closure glaucoma occurs when the distance between the cornea and the iris gets too close. Then the fluid circulating inside the eye, the aqueous humor cannot flow out and the pressure builds up, often very suddenly, causing severe pain. The angle closure can be intermittent, so patients notice pain at night or going into a dark theater. This is serious, see your eyemd right away.

Sight threatening: Acute angle closure is a condition where the drainage system of the eye is blocked by the iris (the colored part of the eye). This causes the eye pressure to skyrocket. Symptoms include nausea, vomiting, headache, blurred vision, red eye and haloes. This can cause sight loss if not treated promptly.

Acute Angle closure: Acute angle-closure glaucoma is a sudden severe rise in intraocular pressure that occurs when the iris blocks the eye's trabecular meshwork , where the eye's fluid drains.
