Precipitous increase in IOP
Redness and pain with acute vision loss and often headache, nausea, and vomiting

Aqueous suppressants
Aqueous outflow facilitators
Laser trabeculoplasty, filtering surgery with or without antimetabolite
Drainage devices
Ciliary body destructive procedures
Glaucoma Management

Risk factors: age, genetics, smoking, hypertension, fair skin
Diagnosis: presence of drusen (dry form, yellow deposits under retina) or of choroidal neovascularization (CNV) (wet form), formation of new blood vessels in the choired layer; CC is dark spot in the central field of vision
Age-Related Macular Degeneration
Vitamin C, vitamin E, zinc, lutein, zeaxanthin—to decrease risk of CNV in dry forms
