Glaucoma is caused by an increased pressure in the eye, which can damage the eye's nerve (optic nerve). In a normal and healthy eye, fluid will flow normally through the eye without obstruction. With patients suffering from glaucoma, the fluid that is pumped into the eye cannot drain out of the eye causing a buildup of dangerous pressure that can damage the optic nerve, causing vision loss. In most causes those suffering from glaucoma won't recognize their symptoms, which is why it is important to annually scheldule your eye examine. As the disease progress it can be noticed by pain and pressure in and around the eyes, rainbow colors around bright lights, foggy vision, or sudden eye lose.
Selective Laser Trabeculoplasty (SLT): This low level laser is used for open-angle glaucoma patients to open the fluid streams within their eye. This safe and effective laser creates tiny holes within the eye so proper filtration can occur. With the state-of-the-art technologies that are used, minimal heat damage takes places on the remaining tissue area. Because of the safe beam, multiple procedures can be conducted if necessary. This surgery entails an eye drop treatment regimen which is conducted by the patient at home in between treatments.
Argon Laser Trabeculoplasty (ALT): For the treatment of primary open-angle glaucoma (POAG). The laser beam opens the fluid channels of the eye, helping the drainage system work better. In many cases, medication will still be needed. Usually, half the fluid channels are treated first. If necessary, the other fluid channels can be treated in a separate session another time. This method prevents over-correction and lowers the risk of increased pressure following surgery.
Micropulse Laser Trabeculoplasty (MLT): MLT provides the same pressure-lowering effects as SLT and ALT. It is unique in that it uses a specific diode laser to deliver laser energy in short microbursts. MLT is a relatively new laser procedure.
Laser Peripheral Iridotomy (LPI): For the treatment of narrow angles and narrow-angle glaucoma.Narrow-angle glaucoma (also known as angle-closure glaucoma) occurs when the angle between the iris and the cornea in the eye is too small. This causes the iris to block fluid drainage, increasing inner eye pressure. LPI makes a small hole in the iris, allowing it to fall back from the fluid channel and helping the fluid drain.
Laser Cyclophotocoagulation: An alternative to filtering microsurgery that is typically used later in the treatment algorithm. Several different types of lasers can be used to hamper the ciliary body's ability to make fluid and, thus, lower the eye pressure. The procedure may need to be repeated in order to permanently control glaucoma.
iStent is the smallest medical device ever approved by the FDA. It is placed in your eye during cataract and glaucoma surgery and is so small that you won’t be able to see it or feel it after the procedure is over. iStent is designed to create a permanent opening in your trabecular meshwork, and works continuously to improve the outflow of fluid from your eyes to help control eye pressure.iStent improves aqueous outflow and reduces IOP in patients with mild to moderate open-angle glaucoma.
There are few surgeons who are experienced enough to be able to preform this surgery; however, Dr. Rosenthal has begun making iStent surgery a regular and successful procedure.
