eye
| Question | Answer |
|---|---|
| pterygium | trianglular opaqu wing of bulbar conjunctive overgrows toward the center of the cornea -looks membranous, transluecen,t and yelo to white -occurs; hot, dry, sand climate |
| hyphmea | blood in anterior chamber result of blunt trauma or spontaneous hemorrhage -gravity settles blood |
| hypopyon | purulent matter in anterior chamber occurs with iritis with inflammatio in anterior chamber |
| periorobital edema | lids are swollen and puffy -occurs: local infections; crying + systematic conditions such as CHF, renal failure, allergey, hypothyroidism |
| subjunctiva hemorrhage | -red patch on sclera, sharp edges -occurs: from increased intraocular pressure froom coughing sneezing, weight lifting, childbirth |
| dacryocystitis | -inflammation of lac sac -infection and blockage of sac and duct, pain, warmth, redness, and swelling occur below inner canthus -tearing present |
| dacryoadenitis | -inflammation of lac gland -infection of lac gland -pain, swelling, and redness occur in outer 3rd of upper lid -occurs: mumps, measles, infections, monoucleosis |
| basal cell carcinoma | -occur on lower lid and medial canthus -looks like papule with an ulcerated center -rolled-cut pearly edges |
| hordeolum | stye -staphylococcal infection of hair follicles at lid margin -painful, red, and swollen-pustule |
| Chalazion | beady nodule protuding on the lid; an infection or rentention cyst -nontender, firm, discrete swelling w/freely movable skin overlying the nodule |
| Entropin | -lower lid rolls in because spasm of lids or scar tissue -constant rubbing of lashes may irritate cornea -foreign body sensation |
| iritis | -circumocorneal redness -deep dull red halo around iris + cornea -pupil shape may b irregular from swelling of iris -person has marked photophobia, constricted pupil, blureed vision and throbbing pain |
| ectropion | lower lid is loose and rolling out, does not approximate to eyeball -puncta; excess tearing results -do not drain correctly over corner and toward medial canthus |
| ptosis | -dropping upper lid -occurs: neuromuscular weakness, oculormotor cranial nerve 3 damage -sleepy appearance and impairs vision |
| enophthalmos | -sunken eyes -bilateral caused by loss of fat in orbits and occurs w/dehydration and chronic wasting illness |
| exophthalmos | -protuding eye -lid lag, upper lid rests well above the limbus and white sclera visible |
| vessel nicking | localized marrowing in vein caused by arteriole crossing -seen with hypertension and arteriocolosis |
| excessive cup-disc ratio | -with primary, open-angle glaucoma, the increased ICP decreased blood supply to retinal strucutres -vessels displaced nasally |
| papilledema | -choked disc -increased intracranial pressure causes venous stasis in globe, showing redness, congestion, + elevation of the disc, blurred margins, hemorrhages, absent venous pulsation -visual acutiy not affected |
| optic atrophy | -disc pallor -result: decreased visual acuity, and decreased color vision, decreased contrast sensitivity |
| conjunctivits | -purulent discharge accompanies bacterial infection |
| acute glaucoma | -circumcorneal redness around iris, with dilated pupil -pupil is oval, dilated; cornea looks steamy and anterior chamber is shallow -person experiences a sudden clouding of vision, sudden eye pain, + halos around lig |
| corneal abrasion | -blunt eye injury, irregular ridges usually visible only when flourescent stain reveals yellow-green branching -to player of cornea removed from stractches or poorly fitting or over worn contact lenses |
| cover test (uncovered) | jumps to fixate on designate point, it was out of algnment |
| phoria | mild weakness, apparent only with the cover test and less likely to cuase amblyopia than tropia but still possible |
| esophoria | nasal (inward) drift |
| exophoria | temporal (outward0 drift |
| corneal light reflex | 1. symmetric: pseudos and rabisums-has appearance of strabismus bc of epicanthic fold (normal for young child) 2. asymmetric; strabismus-true disparity of the eyes axes. this constant malalighment is also termed tropia and is likely to cause amblyopia |
| diabetic retionopathy | microaneurysm: are round puncate red dots that are localized dilations of a small vessel. Edges are smoth and discrete -intraretinal hemorrhages: dot shapped, deep look splattered on blurred irregualr edges, occur with hypertension |
| Cover test (covered) | if weaker eye, drifts to relazation position (esophoria, exophoria)eye is uncovered it it jumpts to reestablish fixation, weakness exist |
