What is Laser Iridotomy?
Unlike similar procedures, laser iridotomy is used as a preventative procedure rather than a treatment procedure. It has been in use since the mid-1980s and has proved to be very successful in stopping the spread of closed-angle glaucoma. In closed-angle glaucoma, the angle is closed in many or most areas, causing increased eye pressure, which leads to optic nerve damage, and possible vision loss. This rise in eye pressure may occur suddenly (an acute attack of angle-closure) or gradually. There are also precursor forms of the disease in which the angle is closed but the eye pressure is not high and the optic nerve is not affected yet.
How Does The Procedure Work?
By using lasers, we’re able to create a hole on the outer edge of the iris, leading to an opening of the angle. After the angle is made larger due to the procedure, the trabecular meshwork is exposed and fluid outflow is enhanced. If this fluid does not have proper streams, it can cloud up your vision, leading to glaucoma.
The procedure should only take 5-10 minutes and patients receive anesthetic drops before the procedure so pain is minimal to non-existent. We typically pretreat the eye about a half-hour before the procedure in order to make the pupil small.
Who Should Have This Treatment?
It is recommended in eyes that have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes that have a closed-angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment. In a recent large prospective study of such eyes, it was shown that there was an overall low risk of developing high eye pressure but the risk was lower among eyes that received laser iridotomy compared to those that did not.
