A

GP/physician

–when positive during history taking
-interpretation of their outcomes
-medical systems review
Ophthalmologist
-for care if they fit criteria for referral

53
Q

What are the three essentials of therapeutic management of anterior uveitis?

A

Determining underlying cause
Controlling the inflammation
Controlling complications of
-the inflammation
-the treatment
Must ask yourself why a patient has uveitis before you proceed

54
Q

Do you treat acute anterior uveitis aggressively or conservatively? Explain why (2).

A

Aggressively
-minimise structural damage
-relieve symptoms of pain/photophobia

55
Q

Are topical NSAIDs commonly used for acute anterior uveitis? Explain.

A

No, too weak for acute

56
Q

What are the two principal drug classes used to treat acute anterior uveitis? What may sometimes be done in severe cases?

A

Topical corticosteroids
Cycloplegia/mydriasis
Periocular steroid injection for severe cases

57

A

Break recently formed synechiae
Prevent new synechiae forming

58
Q

Can topical steroids be used for posterior uveitis? Explain.

A

No, they do not have enough penetrance
-generally adequate enough for AAU

59
Q

What is the dosage like for steroids to treat acute anterior uveitis?

A

High initially, adjust downwards quickly but according to response

60
Q

How long does treatment with steroids last for acute anterior uveitis?

A

Several weeks (6 to 8)

61
Q

What is a general rule of thumb on how to taper steroid use?

A

Taper over however long the steroids have been used for
i.e. if used for a month, taper over a month

62
Q

Define standard dosing.

A

Regular application of drug

63
Q

Define pulse dosing. When is it useful? Is it used for typical acute anterior uveitis?

A

High dose followed by rapid (or no) taper as its unlikely to invoke systemic effects

Q

Give an example of a pulse dose over a week.

A

Day 1-3 - q2h (waking hours)
Day 4 - q4h
Day 5 - tid
Day 6 - bd
Day 7 - stop

65

Is there a risk of rebound inflammation or IOP rise with pulse dosing (assuming they are not an IOP responder)?

A

More or less no risk of either

66
Q

What should dictate how you taper steroids?

A

Acceptable improvement in condition

67
Q

When considering topical steroids for acute anterior uveitis, is it better to over-treat or under-treat? What is the most common reason for failure to control inflammation?

A

Over-treat
-most common reason is insufficient dosing

68

What is the most effective topical steroid for acute anterior uveitis? Which has the highest anti-inflammatory effect? Explain why. Note the most popular choice and the one with the highest IOP response.

A

Pred forte
-most effective intraocular steroid
-most popular/first choice
Maxidex
-highest anti-inflammatory effect

-infection appears

75
Q

Suppose you are streating acute anterior uveitis with steroids and IOP rises or an infection appears (or both). Can you withdraw steroids without tapering? Explain (3).

Cannot withdraw anti-Inflammatories without correct tapering
Consider
