Q

IOP may increase

A

Trabecular congestion may reduce outflow

Also consider iatrogenic increase in IOP due to steroid response

A

Epi-capsular stars
PSC
Mature cataract

21

22
Q

Bilateral uveitis suggests you are dealing with which type of uveitis?

A

endogenous and chronic types of uveitis, especially if granulomatous

23
Q

Unilateral uveitis is more common in

A

Sarcoid, Behcet’s, foreign body, post-surgical events

24
Q

When is uveitis considered chronic?

A

Persistent

Tends to relapse less than three months after discontinuing treatment

25
Q

Which chronic diseases cause non-granulomatous uveitis?

A

A 
Tuberculosis (get granulomatous elsewhere)
Sarcoidosis
Syphilis 
Cat scratch fever (comes from kittens)
Fungal infections
27
Q

What are the three events that occur in uveitis?

A

inflammation of any of the structures of the uveal tract
Disruption of the blood-ocular barrier
Infiltration of leukocytes and protein leakage

28
Q

Duration and onset of acute Anterior uveitis.

A

Sudden onset
Moderate to severe pain
Duration 6-12 weeks with/without therapy
non-granulomatous disease with fine keratic precipitates (precipitate in endothelium)

29
Q

Non-Caseating Granulomatous

A

hard inside
Chalazion
Epidermoid/dermois cyst
Sarcoidosis

30
Q

Caseating Granulomatous

A

soft cheesy

TB granuloma

31
Q

What are the characteristics of recurrent uveitis

A

Third episode reclassifies patient as recurrent
Requires complete medical evaluation
Repeated episodes with inactivity longer than 3 months

32
Q

Which diseases are heavily associated with males?

A

trauma
ankylosing spondylitis
Reiter’s syndrome

33
Q

Which diseases are heavily associated with females?

A

Granulomatous type double in females due to sarcoidosis
Childhood uveitis greater in females due to
Still’s Disease:

34
Q

Which type of uveitis is most common by race?

A

Blacks: sarcoidosis Especially in black females, Southeastern US.
Asians: Vogt-Koyanagi-Harada Syndrome, Bechet’s disease.

35
Q

Which type of uveitis is associated with Type A personality?

A

Pars Planitis
high stress
trauma with CL wear

A

Histamine
Bradykinin
Serotonin

37
Q

Which corneal disease causes severe swelling when the patient also has uveitis?

A

Fuch’s endothelial dystrophy

38
Q

Give examples of endogenous causes of uveitis?

A

Pars planitis-Uveitis with snow banks on ora or pars plana.
Fuch’s heterochromic iridocyclytis.

Mild idiopathic anterior chamber inflammation

A

Possner-Schlossman Syndrome/ Glaucomatocyclitic Crisis

41
Q

Pain is most likely associated with chronic or acute uveitis?

A

Acute uveitis may be severe and debilitating

Chronic uveitis may be asymptomatic ( sometimes)

42
Q

vision symptoms

A

Acute uveitis: vision is usually normal to hazy

Chronic uveitis: the vision may be worse than the symptoms

43
Q

stromal edema

A

present in “hot” acute anterior uveitis, present with dense KP
Present in advanced and chronic cases

44
Q

Band keratopathy is common in which type of uveitis?

A

Band Keratopathy may develop in recurrent/ advanced or chronic cases

45
Q

may form on the pupil border, anterior surface of the iris or angle locations.
associated with granulomatous disease
common in sarcoid
