Closed-angle glaucoma usually affects both eyes over time. When sudden (acute) closed-angle glaucoma occurs in one eye and laser surgery has been done on that eye, laser iridotomy is usually done on the other eye to prevent the condition from developing. Without treatment, there is a 50% chance that closed-angle glaucoma will also develop in the unaffected eye.
High pressure in the eyes may continue after laser iridotomy. The person may need to be monitored closely for this even after the procedure. Some people may require additional treatment, such as eyedrops, to lower the eye pressure.
