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.

To our valued patients,

During these challenging times, we feel it’s especially important to keep you informed of what we are doing to keep you safe. The health and safety of our patients is our primary goal. The impact of the COVID-19 pandemic remains fluid and as such we have made the following changes in our clinic as we strive to maintain the highest standards of care for you our patients:

* Modified schedule. Anyone entering the clinic will need an appointment. There will only be one patient allowed in the clinic at one time to ensure social distancing. Other family members are not permitted in. You can continue to call the clinic to make these appointments. Seniors 60 and over will kindly be asked to reschedule for a safer time in the future.

* All patients must sign a form declaring that they do not have a fever, sore throat, cough, runny nose and other flu-like symptoms including aches and pains. They also must declare that they are practicing social distancing in accordance with the Governor of Washington’s mandate.

* All common surfaces will be disinfected in accordance with current guidelines and protocols after each and every patient and before a new patient enters the clinic. This includes instruments and eyeglass frames that have been handled.

Thank you for your patience and understanding during this difficult time. Our thoughts and prayers are with you. Together, we will get through this.

Warmest regards,

Dr. Osborne and staff
