Vocab and Diseases Flashcards
Complete loss of smell
Anosmia
A decreased sense of smell
hyposmia
an increased sense of smell
hyperosmia
a perversion of smell
parosmia
abnormally disagreeable smell
Cacosmia
involves the optic nerve or tract, the most common cause is MS. Lesion of the visual appartus.
Retrobulbar neuritis
Lesion of the visual appartus. Includes various forms of retinitis.
Optic or bulbar neuritis
Lesion of the visual appartus. Commonly seen symptom of increased intracranial pressure due to brain tumors, abscesses, hemorrhage, HTN.
Papilledema aka “Choked disc”
Lesion of the visual appartus. Associated with decreased visual acuity and a change in the color of the optic disc.
Optic Atrophy
Lesion of the visual appartus. Caused by processes that involve the optic nerve and DO NOT produce papilledema.
Primary Optic Atrophy
Lesion of the visual appartus. Sequel of papilledema.
Secondary Optic Atrophy
Lesion of the visual appartus. May be due to tabes dorsalis, MS, or hereditary.
Primary (simple optic atrophy)
Lesion of the visual appartus. May be due to neuritis, glaucoma, or increased intracranial pressure.
Secondary Optic atrophy
Lesion of the visual appartus.. Corneal scars, and arteriosclerotic changes in the retina may occur. Tumors and other lesions may interrupt optic pathways.
Opacities of the lens
Caused by tumors at the base of the frontal lobe. Characterized by ipsilateral blindness, and anosmia and contralateral papilledema.
Foster Kennedy Syndrome
Cerebromacular degeneration with severe mental deficiency occuring in Jewish families and is associated with blindness, optic atrophy, and a dark CHERRY RED spot in place of the macula lutea.
Amaurotic Familial idiocy (AKA Tay-Sachs Disease)
Reacts only to accommodation. Neither direct or indirect reaction to light.
Argyll Robertson Pupil
Characterized by a tonic pupillary reaction and the absence of one or more tendon reflexes. Pupil is “myotonic” slow reaction/contraction
Holmes-Adie Syndrome
Outward/lateral movement of eye?
Exotropia
Inward/medial movement of eye?
Esotropia
Deviation of bilateral eye alignment
Heterotropia
Hypertropia
move eyes up
move eyes down
Hypotropia
An example of a lesion affecting the Medial Longitudinal Fasciculus (MLF) would be?
Multiple sclerosis
Involuntary eye oscillations. the result of uncoordinated attempts at controlling eye movement.
Nystagmus
a pupil that reacts to light very slowly, remains constricted longer, then dilates slowly. Occurs most often in young women and is benign.
Holmes- Adie Syndrome aka Adie’s Pupil/Tonic pupil
Reacts only to accommodation. Neither direct/indirect reaction to light.
Argyll Robertson pupil
**Sympathetic hypofunction due to lesions of the neck PROXIMAL to the carotid artery bifurcation that compresses ascending sympathetic fibers is what?
Horner’s Syndrome
