Q
A

Acute anterior uveitis
* Most common form of uveitis
* Idiopathic
* Unilateral
* Pain, redness, watering, photophibia, blur
* Good prognoisis
Non-infectious causes:
* Immune mediated (Ankylosing spondylitis)
* Juvenile idiopathic arthritis
* SLE
* Sarcoidosis
* Behcet’s disease
* Vogt-Koyanagi - Harada disease
* Fuch’s heterpchromic iridocyclitis
Infective causes:
* Lyme disease
* Syphilis
* TB
* Herpes
* Toxo
Signs:
* Conj. Injection
* Corneal edema
○ KP’s (non-granulomatous)
○ Mutton fat KP’s (granulomatous)
○ Stellate KP’s (Fuch’s uveitis syndrome)
* AC cells/flare, Hypopyon, hyphaema
* Iris nodules (Busacca/Koeppe’s), Atrophy, PAS, Neovasc.
* Lens pigment ring, cataract
* IOP fluctuations
○ Low > CB inflammation
○ High > angle closure
* Vitritis
Complications:
* Corneal edema, band keratopathy
* Iris synechae (Pos/Ant)
* Angle PAS
* Lens cataract
* CB membrane
* Secondary glaucoma
