Opthalm Flashcards
two types of ARMD
dry
wet (neovascularization, leakage of fluid)
what do you see in dry vs wet ARMD
dry: drusen (yellow spots)
wet (red patches of haemorrhage)
Mx for wet ARMD
anti-VEGF
bacterial keratitis
most common cause, Px, Mx
bacterial infection of the cornea
assoc. with contact lens wearers (pseudomonas!!!!) /corneal abrasion
red eye, lacrimation, feeling of foreign body in eye
Mx: topical ABs
blepharitis and MX
chronic eyelid inflammation
Mx: lid hygiene,
carotid cavernous fistula
Px
connection made between cavernous sinus and carotid artery
Px: pulsatile exophthalmos; conjunctival injection, optic bruit
cherry red spot on a pale retina
central retinal artery occlusion
stormy sunset
describe it and what causes it q
flame haemorrhages, cotton wool spots
central retinal vein occlusion
chronic open angle glaucoma and Px
increased resistance to trabecular meshwork = less drainage of aqueous humour.
gradual vision loss, tunnel vision
Mx of COAG
- surgical: selective laser trabeculoplasty
- if they don’t want SLT: latanoprost
headache, nausea, vomiting
severe eye pain, red eye, blurry vision
what is this? Mx
acute angle closure glaucoma
Mx: pilocarpine; acetazolamide; timolol
peripheral iridotomy
pupil presentation in angle closure glaucoma
fixed-dilated
3rd nerve palsy, eyes rest at what position
down adn out
scleritis vs episcleritis
both present w red eye
scleritis is more severe pain on eye movement
episceral vessels blanch when pressed, scleral do not
endopthalmitis
Px and Mx
infection inside the eye presenting with severe eye pain, vision loss
happens after cataract surgery
Mx: intravitreal vancomycin
dendritic ulcers are pathognomic for:
herpes simplex keratitis
Argyll-robertson pupil
bilaterally small pupils
constrict when focused on a near object, do not constrict upon bright light
neurosyphilis!!!!!!
optic neuritis triad and Mx
ocular pain
vision loss
colour blindness
IV methylprednisolone
swollen, red, painful eye
recently had a sinus infection
what is it? and Mx

IV antibiotics
