What is Acute Angle Closure Glaucoma?
Acute angle closure glaucoma occurs when the mechanism responsible for draining the aqueous fluid inside the eye, the anterior chamber, closes and becomes blocked. This causes a swift, rapid rise in the pressure inside the eye, which in turn causes compression on the optic nerve and glaucomatous damage. Acute Angle Closure Glaucoma

What causes Acute Angle Closure Glaucoma?

There are several different etiologies for acute angle closure glaucoma, including, but not limited to:

  • Abnormal iris configuration that blocks the anterior chamber

  • Forward movement of the lens inside the eye, blocking the normal flow of aqueous inside the eye

  • Neovascular or fibrovascular membrane that pulls the angle closed (aka neovascular glaucoma)

  • Certain medications can have a side effect of angle closure

Symptoms of Acute Angle Closure Glaucoma:

Symptoms of acute angle closure glaucoma include pain, blurred vision, colored halos around lights, a frontal headache, nausea, and vomiting.


Treatment of Acute Angle Closure Glaucoma:

Treatment varies depending on the etiology of the angle closure. However, primary treatment is generally centered around lowering the eye pressure. This is done by both eye drops and oral medications. Surgery may be required as well.
