What is strabismus

Ocular misalignment

11

treatment of strabismus

Forced used of eye with defect. Cover normal eye, or put cyclopegic drops in normal eye (make it blurry)

12

Abnormal findings for strabismus

constant stabismus at any age, eye deviation after 4 months of age, asymmetry of corneal light reflexes, asymmetry intensity of red reflexes, deviation on cover test, torticollis or head lift

13

Erythema multiforme usually follows what kind of infection?

"Target" lesions. Follows herpes simplex infection.

14

Measles rash compared to rubella rash.

Measles tend to be more severe than rubella. Also a/w high fever (up to 104), coryza, and malaise.

Allergic contact dermatitis is an example of what kind of hypersensitivity

Type IV which is aka cell-mediated, delayed-type

26

type 1 hypersensitivity

aka immediate hypersensitivity. IgE mediated. Allergen binds and cross-reacts with 2 IgE molecules attached to mast cell. Atopy, urticaria, anaphyslaxis

27

Type 2 hypersensitivity.

aka antibody mediated hypersensitvity. Cytotoxic reactions involve specific reactions of IgG or IgM to cell-bound antigens. The antibodies then activiate complement resulting in cell damage. Example hemolytic anemia

28

Type 3 hypersensitvity

aka immune complex mediated hypersensitivity. Antibodies of IgM or IgG form complexes with antigens and nonspecifically activate the complement cascade and other inflammatory processes. Examples include serum sickness.
