MEDICAL VIEWS: ‘MACULAR DEGENERATION RESEARCH’

Macular degeneration is a leading cause of visual impairment in people over 65 and can lead to blindness. One in three people will eventually suffer some degree of macular degeneration, which is caused by abnormal blood vessels under the retina, the light-sensitive part of the eye. We treat both the more common “dry” as well as the more dangerous “wet” forms of macular degeneration. While there is currently no cure for this disease, we offer the latest treatments to reduce the risk of vision loss and blindness. These include anti-VEGF drugs—which attack proteins that create the abnormal blood vessels that cause macular degeneration—and photodynamic therapy, in which patients ingest medication that is then activated with a laser.

COMMENTARY:

This high quality video shows several aspects of macular degeneration. It discusses treatments with stem cells that are in the research phase; in the future there may be replacements for the abnormal support cells, the vascular cells and pigmented epithelium, that are diseased in macular degeneration.

Current treatment centers on control of abnormal blood vessels either by photo active laser, laser coagulation, or anti-VEGF.
Macular degeneration has two forms, wet and dry. The wet macular degeneration has accumulations, or Drusen, under the epithelium. There are also machines to check the thickness of the macula, which is an aid in diagnosis.

The main symptom of macular degeneration or loss of vision especially in The center of the visual field, which is essential for reading.
As I mentioned in my podcast, I made a posting on macular degeneration that includes an amsler grid. Some early symptoms of macular degeneration include waviness of the lines of this grid. Certainly if you have any visual distortion or loss you should see an ophthalmologist.

If your medical plan permits it, I feel but a regular check buy an ophthalmologist approximately every 6 to 12 months, is very useful. My own ophthalmologist checks my  retinal thickness, optic nerve, pressure and peripheral Field ( to pick up glaucoma) as well as my vision on each visit.
