What procedure is used to prevent or treat angle-closure glaucoma?

Laser peripheral iridotomy is the standard first-line treatment in closed angle glaucoma and eyes at risk for this condition. It has been used since 1984 both as treatment and prevention of the disease.

How do you manage angle closure?

Management goals for the angle closure spectrum are elimination of its underlying cause and control of IOP to prevent optic nerve damage. Treatment options include observation, laser peripheral iridotomy (LPI), laser iridoplasty, lens extraction, medical therapy, and glaucoma surgery.

What do you do in an angle closure attack?

Acute angle-closure glaucoma treatment

  • Eye drops containing beta-blocker medication (to reduce fluid production in your eye) and steroids (to reduce inflammation) – for example, timolol.
  • An injection of a medicine called acetazolamide.

What is the difference between iridotomy and Iridoplasty?

Currently, opinion is that laser peripheral iridotomy (LPI) alone is not sufficient to prevent disease progression. Laser peripheral iridoplasty (LPIP) is an alternative and effective way of widening the angle recess in eyes that are affected by primary angle closure (PAC).

How can acute angle closure glaucoma be prevented?

Prevention. 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 fluid drains. If they think your risk is unusually high, they may suggest laser treatment to hold off an attack.

Why is pilocarpine contraindicated in angle closure?

Pilocarpine is also contraindicated in uveitis and secondary glaucoma because its miotic effect may predispose to posterior synechiae and pupillary occlusion. A frequently observed side effect after prolonged use is conjunctival hypersensitivity which warrants dilution of the pilocarpine or discontinuance of this drug.

Is angle Closure an emergency?

Glaucoma refers to a range of ocular diseases that ultimately result in increased intraocular pressure (IOP) and decreased visual acuity. Acute angle-closure glaucoma (AACG) is an ocular emergency and is differentiated by its acute presentation, need for immediate treatment, and well-established anatomic pathology.

How long does laser iridotomy last?

The effects can last 24-72 hours after the procedure. Long term effects of laser PI include: cataract formation, visual dysphotopsias (glares, halos, lines, spots).
