Opthalmology Flashcards
(27 cards)
management of acute closed angle glaucoma
- refer
- medicate
- laser peripheral iridotomy
- lens extraction
anterior uveitis appearence
irregular and small pupil
hypopyon
corneal abrasion
epithelial breech without keratitis
symptoms of retinal detachment
floaters
flashes
field loss
fall in acuity
management of retinal detachment
urgent vitrectomy and gas tamponade with laser coagulation
retinal vein occlusion management
can only be managed actively if ischaemic cause
mx: panretinal photocoagulation
symptoms of chronic open angle glaucoma
peripheral vision loss
aspects of annual eye screening for diabetic patients
- fundus photography
- fluorescin staining
hypertensive eye disease
- silver wiring
- AV nipping
- flame haemorrhages, cotton wool exudates
- papilloedema
cataract symptoms
dazzling bright lights
haloes
night vision loss
retinoblastoma symptoms
strabismus
leukocoria
longer term management of acute closed angle glaucoma
bilateral laser peripheral iridotomy
(once IOP has decreased)
causes of RAPD
optic neuritis/atrophy
retinal disease
causes of fixed dilated pupil
acute glaucoma
mydriatics
CN3 compression
anterior uveitis
pain
photophobia
blurred vision
small/irregular pupil
hypopyon
what is hypopyon
pus in anterior chamber
cause of dendritic ulcer
herpes simplex
central retinal artery occlusion
- dramatic unilateral vision loss
- RAPD
- pale retina with cherry-red macula
causes of central retinal artery occlusion
GCA
Thromboembolism
Management of central retinal artery occlusion
if seen within 6 hours = inc retinal blood flow by decreasing IOP
- occular massage, surgical removal of aqueous, anti-HTN
treatment of wet AMRD
photodynamic therapy
VEGF inhibitors
diabetic pre-proliferative retinopathy
cotton wool spots (infarcts)
venous bleeding
dark haemorrhages
diabetic proliferative retinopathy
new vessels
pre-retinal vitreous haemorrhage
retinal detachment
symptoms of cataracts?
blurred vision
dazzling bright lights
