Tory Prestera, M.D., Ph.D., announced today that he is the first San Diego physician to perform Selective Laser Trabeculoplasty Laser Trabeculoplasty
In this procedure the laser attempts to open the normal drainage channels of the eye so fluid can drain more effectively.

Primary glaucoma in which the aqueous humor has free access to the trabecular reticulum. Also called simple glaucoma. , a leading cause of preventable blindness in Americans over 40 years of age.
The U.S. Food and Drug Administration cleared the Selecta(R) 7000 Glaucoma Laser System in March 2001 as the only machine that can be used to perform the treatment. Produced by Lumenis Inc. of Santa Clara, Calif., the machine lowers intraocular pressure by using short pulses of low energy laser light to selectively target pigmented cells in the trabecular meshwork (or eye tissue), while preserving surrounding tissue. The procedure stimulates an increase in the drainage of fluid from the eye, thus lowering intraocular pressure (IOP IOP
IOP Intraocular pressure, see there ).
Open angle glaucoma is the most common type of glaucoma and often occurs when there is an increase in fluid production or decrease in fluid drainage. This imbalance in fluid flow causes an increase in intraocular pressure, which can, in turn, cause damage to the optic nerve resulting in vision loss and even blindness. Laser treatments are aimed at lowering the eye pressure to prevent such damage to the optic nerve.
Traditional treatment methods for open angle glaucoma include eye drops, oral medication, Argon argon (är`gŏn) [Gr.,=inert], gaseous chemical element; symbol Ar; at. no. 18; at. wt. 39.948; m.p. −189.2°C;; b.p. −185.7°C;; density 1.784 grams per liter at STP; valence 0. Laser Trabeculoplasty (ALT), and surgery. In contrast to the "selective" quality of the Selective Laser Trabeculoplasty (SLT) procedure, where specific cells can be targeted, the burn caused by the ALT method destroys some of the normal eye tissue (trabecular meshwork).
An older method, ALT also can produce scarring of the tissue, leading to decreased eye drainage and possible serious complications.
"My patients have successful and dramatic results following the SLT treatment in my office," said Prestera. "For many patients with open angle glaucoma, intraocular pressure was lowered by more than 30 percent. Several of my patients no longer require eye drops. The treatment is quick, usually takes less than 5 minutes and is relatively painless."
Dr. Prestera purchased the SLT instrument in November and has performed more than 50 procedures in his office, to date.

Clinical work has been ongoing in the U.S. for the past five years. SLT was devised by Mark Latina, M.D., at the Wellman Laboratories located in Massachusetts General Hospital Massachusetts General Hospital Health care The major teaching hospital for Harvard Medical School, widely regarded as one of the best health care centers in the world in Boston. Lumenis Inc. received an exclusive license from the hospital to commercialize SLT and market the laser technology. To date, more than 200 physicians in the U.S. and more than 15 in California perform SLT.
