Perrla and Blood shot eye Flashcards
Acute Iritis:
painful, aching, bloodshot eye and small pupil
acute iritis/ anterior uveitis
a. intra- ocular inflammation: anterior chamber/ iris/ cil body
b. multiple etiologies have been reported
classic indications of anterior Uveitis
c. i. onset can be gradual
c. ii. bloodshot eye, a dull, deep seated ache in the eye, Photophobia, come decrease in visual acuity, tearing and small pupil that is poorly reactive to light
d. anterior uveitis is true medical urgency
Acute glaucoma:
painful, blood shot and LARGE pupil
a. Intra ocular inflammation:
edema and or metaplasia of the iris and or cil body
Acute glaucoma diagnostic criteria include:
b. i. Ocular pain: CN V pain, often severe and of rapid onset
b. ii. Nausea/vomiting
b. iii. A nonreactive pupil that is in mid dialation
t/f Acute glaucoma = med urgency
true
Acute glaucoma: key ddx
conjunctivitis/pink eye
Conjunctivitis is not an intra ocular…
inflammation conjunctivitis does not cause changes in pupillary size or shape
normal Perrla and Pupillary reaction to light
- direct and consensual responses to light
- note good vision: is not a prereq for procedure
normal variant Perrla and Pupillary
hippus
abnormal Perrla and Pupillary reaction to light
lack of response on one or both sides
miosis:
a. excessive constriction of pupil
b. can’t dilate in the dark
Mydriasis:
c. excessive dialation of pupil
d. Will not constrict in bright light
Normal-> accommodation triad consist of:
accommodative convergence, pupillary constriction and accommodation of lens for near vision…abnormal is opposite
cardinal fields of gaze: concerns
Look for alignment or misalignment
Second concern: issues with fixation
Third concern: issues with pursuit movements
Possible findings during cardinal fields of gaze:
Normal variants on cardinal fields of gaze:
Hyper dominant eye
Physiologic end point nystagmus of brief duration
Abornal: undershoort or overshoot seen in cerebral disease or acute alcohol intoxication
Abnormal: jittery eye movements early indication of MS
Abnormal: lesions of vestibular/oculomotor/cerebral systems
Sponateous nystagmus with no apparent cause: newly acquired or con
Gaze evoked nystagmus: fixation or posit results very irr nystagmus
Tropias that occur during the pursit movement
