Understanding Wet AMD
Wet age-related macular degeneration is a progressive eye disease. It occurs when abnormal blood vessels grow beneath the macula, a part of the retina at the back of the eye. These blood vessels can leak fluid and blood, leading to the formation of scar tissue and damage to the macula. As a result, central vision becomes distorted or blurred.
The Role of Injections
Injections are typically administered directly into the eye. They contain medications that target the abnormal blood vessels and prevent their growth and leakage. The most commonly used medication for wet AMD is called anti-vascular endothelial growth factor (anti-VEGF). This medication blocks the protein responsible for the growth of new blood vessels. By inhibiting the growth of these vessels, injections can help reduce fluid buildup and minimize damage to the macula. Injections are usually performed on an outpatient basis, and multiple treatments may be required over time.
Effectiveness and Safety
Injections have revolutionized the treatment of wet AMD. Many studies have shown that injections can significantly improve visual acuity and slow down the progression of the disease. Regular injections can help stabilize or even restore vision in some cases. However, like any medical procedure, injections carry some risks. These risks include infection, bleeding, and elevated eye pressure. It is important to discuss these potential risks with your healthcare provider and weigh them against the benefits of treatment. In general, the benefits of injections far outweigh the risks for most patients with wet AMD.
Other Treatment Options
In addition to injections, there are other treatment options available for wet AMD. These include laser therapy, photodynamic therapy, and surgical interventions. Laser therapy uses a high-energy laser to target and destroy abnormal blood vessels. Photodynamic therapy involves injecting a light-sensitive drug into the bloodstream and activating it with a laser. Surgical interventions are typically reserved for advanced cases of wet AMD and may involve removing scar tissue or transplanting healthy cells. Your ophthalmologist will determine the most suitable treatment approach based on the severity of your condition.
