[Laser contribution in angle closure glaucoma]

A better understanding of angle-closure glaucoma mechanisms is necessary to indicate the appropriate treatment.

the aim of our study is to discuss the laser indication in various type of angle-closure glaucoma.

The study investigate 25 eyes of 22 patients who had an angle-closure glaucoma. The mechanisms are an anterior chamber angle blockage in 19 eyes, a plateau iris structure in 4 eyes and a nanophthalmos in 2 eyes.

Laser peripheral iridotomy is the most used technic; it was practised in 19 eyes. Argon laser iridoplasty was practised in 4 cases of plateau iris structure and in 2 patients who had a residual angle closure with a functional iridotomy.

Laser is an effective alternative in the treatment of angle-closure glaucoma and can alleviate the need for high-risk filtering surgery.
