Here are some treatment options for Dry and Wet Age Related Macular Degeneration.
Nutritional supplements and Dry Age Related Macular Degeneration (AMD)
The Age-Related Eye Disease Study 2 (AREDS2) showed that people at high risk of developing advanced stages of AMD benefited from taking dietary supplements. Supplements lowered the risk of macular degeneration progression by 25 percent. These supplements did not benefit people with early AMD or people without AMD.
Following is the supplementation:
- Vitamin C - 500 mg
- Vitamin E - 400 IU
- Lutein – 10 mg
- Zeaxanthin – 2 mg
- Zinc Oxide – 80 mg
- Copper – 2 mg (to prevent copper deficiency that may be associated with taking high amount of zinc)
Another study showed a benefit in eating dark leafy greens and yellow, orange and other fruits and vegetables. These vitamins and minerals listed above are recommended in addition to a healthy, balanced diet.
It is important to remember that vitamin supplements are not a cure for AMD, nor will they restore vision. However, these supplements may help some people maintain their vision or slow the progression of the disease.
Wet AMD treatments
The most common treatment for wet AMD is an eye injection of anti-vascular endothelial growth factor (anti-VEGF). This treatment blocks the growth of abnormal blood vessels, slows their leakage of fluid, may help slow vision loss, and in some cases can improve vision. There are currently three anti-VEGF drugs available: Avastin, Lucentis, and Eylea.
You may need monthly injections for a prolonged period of time for treatment of wet AMD.
Laser Treatment for Wet AMD
Some cases of wet AMD may benefit from thermal laser. This laser destroys the abnormal blood vessels in the eye to prevent leakage and bleeding in the retina. A scar forms where the laser is applied and may cause a blind spot that might be noticeable in your field of vision.
Photodynamic Therapy or PDT
Some patients with wet AMD might benefit from photodynamic therapy (PDT). A medication called Visudyne is injected into your arm and the drug is activated as it passes through the retina by shining a low-energy laser beam into your eye. Once the drug is activated by the light it produces a chemical reaction that destroys abnormal blood vessels in the retina. Sometimes a combination of laser treatments and injections of anti-VEGF mediations are employed to treat wet AMD.

Presbyopia

Presbyopia is an age related condition that effects your ability to focus clearly on near objects like printed text, computer screens and photographs. It primarily affects people over the age of 40 and is not a disease.
When light from a close object enters the eye it naturally comes to focus behind the retina. To focus the light properly the cilliary muscle around your lens contracts, which changes the shape of the lens, allowing the light to focus properly. With Presbyopia, your lens begins to gradually harden as you get older. This hardening of the lens does not allow it to change shape properly resulting in blurred vision.
There are a variety of ways to correct presbyopia including glasses, bifocals, trifocals or contact lenses. LASIK surgery or conductive keratoplasty, known as CK, are also options. Because Presbyopia is a gradual process you will need to consult your eyecare provider regularly to monitor the condition
