Macular Degeneration

Care & Treatment

Dry Macular Degeneration

It’s important to remember that people with dry ARMD and those with large deposits of drusen run a higher risk of developing wet ARMD. The deposits of drusen don’t cause wet macular degeneration (the leaky, abnormal blood vessels are the cause) but people with significant deposits are more likely to develop wet ARMD than those with fewer deposits.

If you have dry ARMD and significant deposits of drusen, research suggests that high doses of certain multivitamins may lower your risk of developing wet macular degeneration. You should ask your healthcare provider if these high-dose multivitamins are right for you. The combination multivitamins are available over the counter; they contain lutein 10 mg, zeaxanthin 2 mg, vitamin E 400 IU, vitamin C 500 mg, and zinc 25 mg. Some research suggests that taking fish oil or eating fatty fish (such as salmon and tuna) may also help.

Wet Macular Degeneration

There are different approaches to treating wet macular degeneration. Effective therapies for wet age-related macular degeneration include vascular endothelial growth factor (VEGF) inhibitor, photodynamic therapy (PDT), and supplementation with zinc and antioxidant vitamins. Medications such as Ranibizumab and similar VEGF inhibitors help slow the spread of abnormal, leaking blood vessels and have been shown to significantly reduce the risk of vision loss. These medications are injected into the affected eye or eyes. Repeated treatments are usually needed. The treatments are usually done in an outpatient setting like the healthcare provider's office or a hospital-based office. This way you don’t have to be admitted to the hospital to get them.

Other treatments include thermal laser therapy and photodynamic therapy.  These are also done in outpatient settings. Laser therapy uses a laser (a highly focused beam of light) to remove the abnormal blood vessels that are damaging the macula. Photodynamic therapy uses a light-activated drug and a low-power laser to target the leaky blood vessels.
