What are some alternatives to laser iris surgery?
Alternatives to Peripheral Iridotomy Surgery. Alternatives to laser iridotomy include a surgical iridectomy in which an incision is made in the eye to remove a portion of the iris. Surgical iridectomy has more significant risks than laser iridotomy and is rarely used anymore. The other alternative is to do nothing, ...
How to treat glaucoma attack?
The treatment is to lower eye pressure using eye drops and potentially oral medications, but the definitive treatment at the time of the glaucoma attack is to perform a laser iridotomy. In this procedure, a tiny hole is placed in the iris to allow the iris to fall away from the drainage area inside the eye.
How to check for drainage in eye?
Using a special mirrored lens in a procedure called “gonioscopy,” your ophthalmologist can check if your eye’s drainage system. done tweaked When the angle is open, your ophthalmologist can see most, if not all, of your drainage system. On the other hand, when the angle is narrow, your ophthalmologist can only see portions of the drainage angle, and in acute angle-closure glaucoma, none of the drainage angle is visible. Gonioscopy is most common way your ophthalmologist can diagnose narrow angles, and you may be diagnosed as a primary angle-closure “ suspect .”
Why do diabetics need a laser iridotomy?
Finally, sometimes there are other reasons that might lean in favor of performing a laser iridotomy, including the need for frequent dilated eye exams in diabetic patients. Dilation causes the iris to bunch up in the angle and can precipitate an angle closure attack.
Is laser iridotomy safe?
However, laser iridotomy has low risk of side effects and is a very safe procedure that prevents a potentially devastating eye condition. Nonetheless, it is important to understand the risks and benefits of laser peripheral iridotomy in order to make an informed decision about whether to undergo the procedure.
