Fundoscopic findings: Drusen Bodies small yellow spots on the retina due to aging and macular degeneration
Fundoscopic findings: Glaucomatous optic nerve head cupping Disc margins raised, lowered central area. BL vessels disappear over the edge of disc. Caused by increased intraocular pressure. Pt will lose peripheral vision. **INCREASED cup to disc ratio
Fundoscopic findings: Cotton wool spots Infarct areas associated with diabetic/hypertensive retinopathy.
Glaucoma Increased intraocular pressure from build up of aqueous humor in anterior eye. Causes optic nerve damage.
