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 cup gets bigger |
|
2 types of glaucoma
|
open angle: painless, silent dz course, impaired outflow of aqueous humor
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
|
