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 TSO Patients,

We will continue taking precautions at our office.

-Our staff will be wearing masks. We also ask that any patient coming to our office wear a mask.

-Patients will call our office when they arrive to check in. Patients will be asked to stay in their cars until we are ready to start the exam.

-Patients’ temperature will be taken upon entry, and they will be asked to sanitize their hands.

-To reduce the amount of people in the office, only the patient is allowed into the exam room unless the patient is a minor or need additional assistance.

-Exam rooms, credit card terminals, counter tops, etc. will be wiped down between patients.

-Patients should call when they come for pickup of glasses and contact lens orders, we will deliver to them curbside.

-Frames that have been handled in the optical will be placed into a tray, and sanitized before they are returned to the frame board.

-Our office will continue to do curbside dispensing for eyeglasses and contact lenses.

Thank you for your support.

Drs. Hassett, Noorali, and Your TSO Staff
