Lasers and Macular Degeneration CT - Your Options for Better Vision

Macular degeneration is a condition commonly associated with age. Age-related macular degeneration (ARMD) is, in fact, the most common cause of vision loss in individuals 50 and older. This condition occurs when the arteries that nourish the retina begin to harden, depriving sensitive retinal tissue of the nutrients and oxygen it needs to properly function. The result of this arterial hardening is a decrease in central vision.

This is an interesting condition, as it affects only central vision to varying degrees. A patient with macular degeneration will maintain peripheral vision, the vision which spreads out to one side or the other. What the patient views directly is what is impacted. Some patients may experience a mild distortion, where a straight line such as a doorway will appear bent or wavy. More advanced cases may lose central vision completely. In these cases, the patient loses his or her ability to perform everyday tasks such as reading or driving.

There are a number of retinal tests which Dr. Gold may perform to diagnose macular degeneration. Early diagnosis and treatment are vital to halting the progression of vision loss. With macular degeneration, there is currently no treatment which can successfully restore lost vision, so our primary focus becomes to maintaining what vision is still intact.

There are two types of macular degeneration - wet and dry. Wet macular degeneration occurs when new vessels form to improve the blood supply to oxygen-deprived retinal tissue. These new vessels are very delicate and break easily, causing bleeding and damage to surrounding tissue. In recent years, lasers have been tested as a treatment for wet AMD.

One treatment for wet AMD is laser photocoagulation. This procedure has been effective at sealing leaking or bleeding vessels in the eye. However, it does not restore vision. The benefit of laser photocoagulation is the prevention of further vision loss.

Photodynamic therapy has proven to be an effective method for halting the growth of abnormal blood vessels in some patients with wet AMD. In many cases, this is the treatment of choice. Treatment is dependent on the specifics of each case, and Dr. Gold will determine the best course of action after a comprehensive consultation. Usually this will involve referral to a retina specialist.

In order to maintain your best vision, regular ophthalmic check-ups are recommended. Schedule a time to stop by and see us!
