Age-Related Macular Degeneration
Transcript of Age-Related Macular Degeneration
Degeneration Signs and Symptoms Differential Diagnosis Age-Related Macular Degeneration also know as AMD is a common eye condition among people age 50 and older. It gradually destroys the macula resulting in a loss of central, “straight-ahead” vision. Blurred Vision
Straight Objects may appear distorted or bent
A dark spot may appear near or around the center of the visual field.
While reading parts of words may be missing.
Eye exam may reveal spots of pigment near the macula and blurring of the macular borders.
Drusen Pathophysiology Myopic degeneration
Central serous retinopathy
Cone dystrophy What is Age-Related Macular Degeneration Population at Risk Etiology Free radicals damage and poor oxygen of the macula. (Montgomery, 2012) (International Eyecare Center, 2012) (Macular Degeneration, 2002) (Reuters, 2008) (Dr. Binal, 2009) Are people age 50 and older
Family history (Macular Degeneration, 2004) (Luzer, 2009) (National Eye Institude, 2009) Two forms of AMD Dry AMD
Wet AMD Dry AMD Wet AMD Most common and form of AMD. It has 3 stateges.It occurs in about 90 percent of the people with this condition. (National Eye Institute, 2009) Is more Advanced AMD and can be more severe. It affects about 10 percent of all people with AMD. (National Eye Institute, 2009) (Macular degeneration, 2002) (Duke University Health System, 2011) (Duke University Health System, 2011) Accumulation of iron, within cells of the retinal pigment epithelium (RPE) may also be involved in cellular damage. Deposition of extracellular material along the inner aspect of the Bruch's membrane.This buildup of material alters the permeability of the Bruch's membrane, resulting in decreased nutrient delivery to RPE cells. Choroidal neovascular vessels break through the Bruch's membrane and are prone to leakage of fluid and lipid, leading to subretinal fluid accumulation. (BMJ Group, 2012) (Friedman, Pineda & Kaiser, 1998) Diagnostic Techniques Testing with an Amsler grid.
Dialated eye exam
Visiual acuity test (National Eye Institute, 2009) Dry AMD Treatments High-dose antioxidant vitamin therapy. Wet AMD Observation
Hot laser therapy
Cold laser therapy (Duke University Health System, 2011) Outcomes Chronic
AMD may advance so slowly that vision loss does not occur for a long time.
The disorder may progress faster and may lead to a loss of vision in one or both eyes.
Get good glasses
Seek help traveling
Obtain specialized appliances (Macular Degeneration Association, 2011)
