sx of macular degeneration
loss of central vision
types of macular degeneration
exudative: less common, more severe --> sudden visual loss from leakage of fluid into retina --> abnormal bv formation
non-exudative: atrophy anda degeneration of central retina, drusen forms under the pigment
clinical findings of glaucoma
increaed iop
damage ot optic nerve
irreversible vision loss
loss of ganglion cells --> atrophy of optic disk

closed angle: occlusion of a narrow angle, very painful with eye dilation. eye is red and painful, n/v/ha **pupil becomes non-reactive**
clinical findings of subconjunctival hemorrhage
red blotchy portions of the eye
non an emergency, looks worse than it is
tx of subconjunctival hemorrhage
resolves in a few weeks on its own, but cold compresses can help
