Loose vascularized connective tissue between conj and sclera
Definition
Episclera
Term
2 types of episcleritis
Definition
Simple and Nodular
Term
Which type of episcleritis is more common?
Definition
80% of cases is simple episcleritis
Term
What is the cause of most cases of simple episcleritis
Definition
Most (70%) are idiopathic
Term
What are some causes of simple episcleritis aside from idiopathic cases
Definition

Collagen vascular dz

Gout

HZV

diffuse or sectoral hyperemia

engorged BV

lacrimation

deep injection

possible AC reaction

Term
Name 5 differential diagnosis for episcleritis cases
Definition

Conjunctivitis

Pinguecula

Keratoconjunctivitis

Anterior uveitis

Scleritis

Term
How may phenylephrine 2.5% be used to diagnose episcleritis?
Definition

When drops of phenylephrine are instilled in a case of episcleritis, the conj vessels will blanch.

They will not blanch if it is a case of scleritis instead

Term
3 important features in diagnosing episcleritis
Definition

Case history

Clinical exam (in natural light and under slit lamp)

Phenylephrine 2.5%

 

Term
Treatment of mild cases of episcleritis
Definition
Generally just supportive treatment like lubricants and cold compresses
Term
3 drug classes that may be used to bring relief to a more serious case of episcleritis
Definition

Topical vasoconstrictors or antihistamine (get red out)

Mild topical steroid

Topical NSAIDs

Term
Treatment for Moderate-severe cases of episcleritis
Definition

Supportive tx

Topical steroid qid

Oral NSAID

Term
2 Oral NSAIDs given for moderate-severe episcleritis cases
Definition

Ibuprofen qid

Naproxen bid

Term
Specify which mild topical steroid is best to use for episcleritis and why.
Definition

Use lotemax

It is better than Pred Forte because it does not raise IOP and a bit more mild. 

Term
How often should you recheck the episcleritis patient to whom you have given steroids?
Definition
Every week
Term
When do you refer your episcleritis patient for systemic workup?
Definition
After 3 recurrences
Term
Which form of episcleritis presents with more pain, simple or nodular?
Definition
Nodular has more intense pain
Term
How is vision generally affected by episcleritis
Definition
Generally unaffected
Term
How do you determine if the elevated, red, nodule that is in the center of the inflammation is due to scleral or episcleral inflammation?
Definition

If the nodule is mobile over the sclera, it is episcleral.

If it is fixed it is scleral

Term
Treatment of nodular episcleritis
Definition

Same as moderate-severe simple form

Topical steroid q2h-qid

Oral NSAID

Term
Follow-up for nodular episcleritis
Definition

Weekly if given steroid

RTC every 2-3 weeks otherwise

Term

Term
How is necrotizing anterior scleritis without inflammation different than the kind with inflammation?
Definition
No inflammation-almost no sxs even though it has the same destructive course
Term
50% of patients with this ocular presentation die from systemic vascular events
Definition
Patients with necrotizing scleritis
