TX:
Pharmacological

Nonpharmacologic
High-dose antioxidants (zinc)
Magnifiers
Large print books
Higher lighting
Computers, tablets, e-readers
Auidobooks & podcasts
Surgery (delays but doesn't cure) for Wet:
Laser surgery

Diagnosis:

Fluorescein angiogram
Optical coherence tomography
Risk factors:
Nonmodifiable
Aging
Race
Eye color
family hx
More often in women
Modifiable
Smoking
Obesity
Poor cardiovascular health
Excessive UV exposure
Heavy consumption of alcohol
Pathophysiology
Nonexudative (dry)
Gradual onset
epithelium detaches in small areas and becomes atrophic
Vision loss is progressively slow
Bleeding can occur (acute vision loss)
The major cause of blindness
Develops more in Caucasians
Exudative (wet)
Vascular endothelial growth factor causes grown of abnormal blood vessels in potential space between choroid and retina
Vessel are prone to leak
Distort vision
Elevated retina from choroid
