Angle-closure glaucoma happens when the drain of the eye becomes blocked and the pressure rises inside the eye. The colored part of the eye, the iris, can be pushed forward inside the eye and close off the drainage angle. If this happens quickly, it is called acute angle-closure glaucoma. If acute angle- Angle closure glaucoma. As in all forms of glaucoma, the end-organ damage is the optic nerve head. A sufficiently elevated IOP will damage the optic nerve, which is the structure that connects what the eyes see to the brain. The "angle" is the part of the eye where the iris meets the cornea and the sclera. The drainage system of the eye is The best way to prevent an acute angle closure glaucoma attack is to get your eyes checked regularly, especially if you're at high risk. Your doctor can keep tabs on pressure levels and how well

Acute Angle Closure Glaucoma
Acute angle-closure glaucoma is an ophthalmological emergency that is caused by a sudden increase in the intraocular pressure (IOP), typically due to an obstruction to aqueous outflow through the trabecular meshwork. This sudden rise in IOP results in the characteristic clinical features of an acutely painful, red eye that is rock-hard on palpation. Immediate medical therapy is required to prevent possible blindness. Miotics (e.g., timolol, apraclonidine), which open the iridocorneal junction, alone or in combination with drugs that decrease aqueous humor production (e.g., acetazolamide) are the first-line treatment. Once the acute attack is controlled, definitive therapy with surgery (e.g., iridotomy, iridectomy) is recommended to prevent recurrence.

Angle-closure glaucoma (also called closed-angle glaucoma or narrow-angle glaucoma) is a type of glaucoma that happens when someone's iris blocks the drainage angle in their eye. You can think of it like a piece of paper sliding over a sink drain. When the drainage angle gets completely blocked, eye pressure begins to rise. Acute angle-closure glaucoma is an ocular disorder essentially linked to specific anatomical formations, particularly hereditary, in which, as of a critical age and influenced by random triggering factors, unilateral or bilateral blockage of the pupil occurs. This leads to closing of the iridocornea. Glaucoma is a group of eye diseases associated with acute or chronic destruction of the optic nerve with or without concomitant increased intraocular pressure ().In the US, glaucoma is the second leading cause of blindness in adults following age-related macular degeneration ().The two main types are open-angle glaucoma and angle-closure glaucoma. Open-angle glaucoma accounts for 90% of all Causes of Angle-Closure Glaucoma. The eye produces a fluid called aqueous humor, which provides nutrition to the eye, and also maintains the eye in a pressurized state. The aqueous humor is continually produced and drains out of the trabecular meshwork, the network of cells and scaffolding material that sits in an area called the drainage angle.

Closed-angle glaucoma is an eye condition caused by too much pressure inside your eye. Learn about the types and symptoms of closed-angle glaucoma. Glaucoma is the second leading cause of permanent blindness in the United States and occurs most often in older adults. There are four general categories of adult glaucoma: primary open-angle and angle-closure, and secondary open and angle-closure glaucoma. The most common type in the United States is primary open-angle glaucoma (POAG). Glaucoma is defined as an acquired loss of retinal Angle recession glaucoma (ARG) is a secondary open angle glaucoma that is associated with ocular trauma. Recession of the anterior chamber angle is a common slit lamp and gonioscopic finding following concussive ocular trauma. A small percentage of these people go on to develop glaucomatous optic neuropathy and vision loss days, months or even years later . Symptoms of angle-closure glaucoma may include headaches, eye pain, nausea, rainbows around lights at night, and very blurred vision. Treatment. Treatment of angle-closure glaucoma usually involves either laser or conventional surgery to remove a small portion of the bunched-up outer edge of the iris.

The evaluation of the eyes is an essential component of the physical examination.There are two types of eye examinations, basic and comprehensive. This article focuses on the comprehensive eye examination, a series of at least twelve tests to screen and diagnose common eye disorders. It should be performed on patients with ophthalmologic symptoms and annually on all individuals ≥ 40 years of Acute angle-closure glaucoma (AACG) is an acute rise in intraocular pressure associated with narrowing of the anterior chamber angle of the eye. AACG is sight-threatening and should be considered in any patient presenting with a red painful eye. Risk factors include increasing age, Asian ethnicity, female sex and hypermetropia.
