Red eye Flashcards
Bacterial keratitis
A compromise to the system
usually with: dry eye, CL over uses, steroid, entropian/triachisis, corneal abrasion
Staphylococcus (MAIN)and streptococcus-oval, yellow/white, dense infiltration
Pseudonomas aeruginosa cause irregular shaped ulcer, rapid progression, can perforate- NEED TO GET TREATED ASAP
fungal keratitis
RAre
rauma
yeat keratitis normally affects cornea with pre-existing disease. Eg candida and STD
viral keratitis
Adenovirus- common and infectious- spreads to BE
herpes simplex- cold sore- primay/recurrent
herpes zoster- shingles- affects 5th nerve?.
what are the main periperhal corneal ulcers
marginal ulcer
moorens ulcer
associated with a systemic disease- acne rosace, syphilis, giant cell arthritis, systemic lupus, rheumatoid arthirisb
bacterial conjuctivitis
gritty sensation
hypereamia-conjuctival hyperaemia worse in fornices
sticky eyelids- mucopurelent discharge
normla VA, cornea and pupil
viral conjuctivitis
Acute bilateral discomfort watery discahrge follicular appearance of papillae sub conjuctival haeomorrhages could get diffuse punctate keratitis- focal sub-epithelial opacitites- anterior strommal infiltrates
inclusion conjuctivitis
chlamydial infection acquired generally
large follicles in fornices and near limbus
lead to superior epithelial keratitis and sub-epithelial infiltrates
treat with tetracycline
can be transmissesd from birth- i.e. neonate phase
Trachoma is:
carried by “”” «_space;this denotes a fly
common in poor coountires, those that live close to a river?
follicular reaction in upper lid
blindness due to scarring in the lid, cornea and conjuctiva, treatment with tetracycline and corneal/lid surgery?
allergic conjuctivitis:
v common
bilateral, chronic, recurrent
u get lacrimation, photophobia, itching, stinging, discharge, hypereamia
topical steroids??
give sodium cromygylcare for prophylaxis- before allergy season
allergy to cl/ sols
Vernal conjunctivitis- long term allergic reaction, swelling
giant papillary conjunctivitis
episcleritis
inflammation of episclera
could be NODULAR/DIFFUSE
unilateral redness/ slight discomfort
steroids if severe?
scleritis
less common
painful- anerior/posterior/scleromalacia vessels are still even when u move lid
diffuse pattern of BV as thicker vessels- more torturous
what does pedals stand for
pain epithelial staining discharge anterior chamber location size/shape
