Back 9

endogenous bacterial endophthalmitis; caused by a ton but:

In North America S. pneumoniae, Streptococcus anginosus group, Group A, Group B Streptococcus cause 30% to 50%
25% are caused by S. aureus and gram negative bacteria ( E. coli, Klebsiella and Serratia ) cause only one-third.

Back 16

Aanthamoeba

Front 17

Back 19

characterized by white blood cells in the aqueous humor.

Front 20

intermeditae uveitis

Back 20

refers to inflammation involving the anterior vitreous, ciliary body and adjacent portion of the retina.

Front 21

posterior uveitis

Back 21

refers to inflammation involving the choroid , retina , both or retinal vessels.

Front 22

panuveitis

Back 22

involves the iris, ciliary body and choroid

Front 23

Two things that micmic uveitis but aren't

Back 23

Propionibacterium acnes or candida

Front 24

Two mc infectious etiologies of uveitis

Back 24

HSV, toxoplasma

Front 25

Back 25

CMV retinitis; fluffy white infiltrates and retinal vasculitis

Front 26

Back 26

Front 27

pt who recently traveled in coastal and rain forest regions of central and west africa has this presentation termed "calabar swellings"

Back 27

Loa Loa (loiasis); nematode transmitted by female tabanid (red) flies; can produce an eye worm in conjunctiva

Front 28

Keratitis

Back 28

Inflammed cornea

Front 29

river blindness

Back 29

onchocerciasis caused by the blood feeding simulium spp. black flies; causes punctate keratitis which can progress to sclerosis keratitis

Front 30

Non-ocular manifestations of onchocerciasis (river blindness)

Back 30

Pruritus: often severe and unrelenting
Nodules: subcutaneous, painless, typically found around bony prominences (iliac crest, greater trochanters, ribs, knees, coccyx and skull)
Severe, disfiguring skin disease: “Leopard Skin”
Lymphatic: lymphadenopathy

Front 31

Toxocara

Back 31

Nematode (round worm) acquired from cat or dog feces; may be in differential dx of sporadic v rb

Front 32

Back 32

ocular toxoplasmosis (t. gondii = intracellular protozoan)

Front 33

Back 33

Microsporidosis; can cause punctuate keratopathy and conjunctivitis

mc ocular effects due to congenital rubella (cataracts = lens clouding)

Back 35

Micropthalmia (small eye)

Front 36

Back 36

Interstitial keratitis has become synonymous with syphilitic disease. It is nonsuppurative inflammation, which is characterized by cellular infiltration of the corneal stroma. Inflammation may be either the direct result of an infectious process or, more commonly, secondary to an immunologic response to a specific foreign antigen.
