Laser peripheral iridotomy makes an opening in the iris allowing the fluid to drain, argon laser trabeculoplasty is aimed at the fluid channel opening to help the drainage system function.
laser iridotomy
Laser iridotomy was first used to treat angle closures in 1956.
The purpose of a laser iridotomy is to allow an equalization of pressure between the anterior (front) and posterior (back) chambers of the eye by making a hole in the superior peripheral iris

The probability of a retinal detachment after capsulotomy is 1.6-1.9%.
The alternative to laser capsulotomy is surgical capsulotomy
Glaucoma laser treatment is used when there is a history of worsening glaucoma because topical solutions have not worked. Medicated eye drops are used to reduce eye pressure, but when the results are not sufficient laser treatment is the alternative.
This procedure is successful in up to 44% of patients treated
Immediately after the procedure, another drop of aproclonidine is applied to the eye.
What are the side effects of laser peripheral iridotomy ?
To perform a laser iridotomy, the ophthalmologist uses a laser, usually an argon or an Nd:YAG laser, to burn a small hole into the iris to relieve fluid pressure behind the iris. If the procedure is an iridectomy, the laser is used to remove.
To determine if laser iridotomy is indicated, the surgeon must first determine if and how the angle is occluded.
