Forms of Macular Degeneration

There are two forms of macular degeneration, dry (non-neovascular) or wet (neovascular). The term neovascular refers to the growth of new blood vessels.

Dry AMD (non-neovascular)

Dry AMD is the most common form of the disease, making up about 85%-90% of all cases of AMD. It is characterized by blurred central vision or blind spots, as the macula begins to deteriorate. Dry AMD is an early stage of the disease and is less severe than the wet form,.

Dry AMD occurs when the aging tissues of the macula begin to thin out and break down. Tiny pieces of white or yellowish protein called drusen begin to appear, which are thought to be deposits from the macular tissue as it deteriorates. The appearance of these drusen are often what leads to a diagnosis of AMD during an eye exam.

With dry AMD vision loss happens gradually, however, the dry form can progress to wet AMD rapidly. There is currently no cure for dry AMD, however there is research that shows that some people can benefit from supplemental vitamin therapy including antioxidants, lutein and zeaxanthin.

Wet AMD (neovascular)

Wet AMD is less common occurring in only about 10 percent of those with AMD. AMD is classified as Wet AMD when abnormal blood vessels begin to grow under the retina and leak fluid and blood into the macula, resulting in blind spots and a loss of central vision. Wet AMD can cause more damage to vision and permanent scarring if not treated quickly, so any sudden blur in vision should be assessed immediately, especially if one is aware that they have AMD. Usually vision loss happens faster and is more noticeable than in dry AMD so the quicker it is treated, the more vision you can preserve.

Dear Patients,

Dr. Lewis Eye Care has made the difficult choice to temporarily close due to the COVID-19 virus pandemic based on the recommendation of the CDC. We cannot perform eye exams while maintaining social distancing, so continuing to see patients at this time could contribute to the spread of the virus.

Our initial plan had been to reopen Monday April 6th. However, as we get closer to that date it is becoming apparent that we may have to be closed for a longer, indefinite period of time.

If you are having an urgent eye health issue, there are some clinics in our area that are seeing patients for emergencies during shorter business hours. You should call ahead to those offices before going to their clinic, as their availability might change day by day. Those clinics could include Vancouver Eye Care at 360-823-2020, Peace Health Medical Group Eye Care at 360-514-7210, and Vancouver Clinic in Salmon Creek at 360-882-2778.

If you need a glasses or contact lens prescription emailed to you from our office, click on the Contact Form link, type in your name, email, and what you are requesting, and we will email you the information you need as soon as we can.

Thank you for your understanding, and please stay healthy during this difficult time.

Sincerely,

Dr. Scott Lewis, OD
