eye pathology Flashcards
what does retinal detachment look like on fundoscopy
crinkling of retinal tissue and changes in vessel direction
non exudative deposition of yelowish extracellular material in and between bruch membrnae and retinal pigment epithelium
gradual decrease in vision
prevent progression with multivitamin and antioxidant supplemtns
dry: age related macular degeneration
nonproliferative damage due to chronic hyperglycemia and treat
damaged caps, leak blood –> lipids and fluid seep into retina–> hemorrhages and macular edema
treat with BG control
rapid loss of vision due to bleeding 2ndary to choroidal neovascularization
treat with anti-VEGF
wet age related macular degeneration
degeneration of macula (central area of retina) that causes disortiorn and eventual loss of central vision (scotomas)
age related macular degeneration
retinal detachment from what
retinal breaks, diabetic traction, inflamatory effusions
aute, painless, monocular vision loss
retina is cloudy with cherry red spot at fovea
evaluate what
central retinal artery occlusion
evaluate for embolic sourece
inherited retinal degen, painless, progressive vision loss beginning with night blindness (rods first)
bone spicule shaped deposits around macula
retinitis pigmentosa
retinal vein occlusion is from blocakge of central or branch retinal vein due to compression from
nearby arterial atherosclerosis
retinal hemorrhage and venous engorgement
proliferative diabetic retinopathy and treat
chronic hypoxia results in new blood vessel formation with tration on retina
treat with photocoagulation, surgery, anti-VEGF
optic disc sweling (usually bilaterl) due to increased ICP 2ndary to mass effect
enlarged blind spot and elevated optic disc with blurred margins
papilledmea
often preceded by posterior vitreous detachmetn (flahses and floaters) and eventual monocular loss of vision like a curtain drawn down
retinal detachment
retinal edma and necoriss leading to scar often from virus
retinitis
ranibizumab
VEGF inhibitor
acute closure closed angle glaucoma
true ophthalmic emergency
increased IOP
very painful, red eye, sudden vision loss, halos around lights, rock hard eye, forntal HA, do not give epinephrine
