Q

What is a scotoma?

A

75
Q

What are the SSx of wet ARMD?

A

10% of cases.
New vessels form to improve the blood supply to oxygen-deprived retinal tissue, but are very delicate and break easily, causing bleeding and damage to surrounding tissue.
Vision loss that occurs acutely (over a period of days or weeks) may represent wet ARMD and requires urgent ophthalmic evaluation.

76
Q

What are the SSx of dry ARMD?

A

Gradual loss of vision in one or both eyes with difficulty reading or driving. Scotomas, or increased reliance on brighter light or a magnifying lens for tasks that require fine visual acuity. Onset is slow and peripheral vision remains intact.

Presence of drusen bodies increases the likelihood of developing ARMD by 23%.

77
Q

What are drusen bodies?

A

Buildup of extracellular materiel in the eye. Can be a normal finding but excessive quantities indicate ARMD.

78
Q

What are a few treatments for ARMD?

A 
Control atherosclerosis. 
STOP SMOKING
Improve metabolic and vascular fxn
Antioxidants
Ozone therapy
Exercise
Reduce exposure to UV light
Dark leafy greens (carotenoids)
