ophthalmology Flashcards

(106 cards)

1
Q

first line management for pt with AAU (new presentations of and recurrent acute anterior uveitis)

A

urgent referral to ophthalmologists within 24hrs
then afterwards may be given prednisolone eyedrops and cylcoplegic eyedrops to dilate the pupil eg atropine

Q

epislceritis vs scleritis

A

episcleritis
- inflammation of episclera which is the outer layer of the sclera
- painless, doesnt affect vision
- episcleral vessels are mobile in response to phenylephrine drops

scleritis
- pain, photophobia and reduced vision
- the vessels in the eye are not moveable and will show no response to phenylephrine drops
