Uvea = (Iris + Ciliary body + Choroid)
- Anterior uveitis: Iritis & Iridocyclitis
- Intermediate uveitis: Pars planitis
- Posterior uveitis: Choroiditis
- Panuveitis: Inflammation of all the layers.
One Liners on Uveitis
- Most common cause of anterior uveitis is Idiopathic
- Most common cause of anterior uveitis in adult: Idiopathic
- Most common cause of anterior uveitis in children: Juvenile Rheumatoid arthritis (now known as juvenile idiopathic arthritis)
- Most common cause of anterior uveitis associated with arthritis is JRA/ JIA
- MC ocular involvement in JRA: Anterior uveitis
- MC cause of posterior uveitis: CMV
- MC cause of posterior uveitis in immunocompetent individuals: Toxoplasmosis
- SLE is not a cause of uveitis.
- Most common extra-articular manifestation of ankylosing spondylitis is Anterior uveitis
- Uveitis is not an extra-articular manifestation of Rheumatoid arthritis [MC extra-articular manifestations of RA is Keratoconjunctivitis sicca (KCS)]
- Rifabutin and Cidofovir lead to drug-induced uveitis
- Most common ocular feature of sarcoidosis: Granulomatous panuveitis.
Signs & symptoms:
- Earliest sign of anterior uveitis: Aqueous flare
- The earliest sign of active anterior uveitis: Aqueous cells
- Hallmark of anterior uveitis: Aqueous cells
- Most diagnostic/ pathognomonic sign of anterior uveitis: Keratic precipitates.
Characteristic signs/ appearances:
- MC symptom of posterior uveitis: Painless diminution of vision (due to macular edema)
- Pupil in anterior uveitis/ iridocyclitis:
- Acute: Irregular and constricted
- Chronic: Festooned pupil
- Characteristic: Festooned pupil
- Iris roseola (pinkish iris nodules) is seen in syphilitic uveitis
- Iris atrophy is pathognomonic finding in: Herpes zoster uveitis
- Feature of heterochromia iridocyclitis: Hypopigmented iris.
- Uveitis with raised IOP (also known as Hypertensive uveitis/ Glaucomatocyclitic crisis/ Posner Schlossmann syndrome) is best managed by Steroids
- Most useful drug to reduce IOP in case of hypertensive uveitis: ?-blockers (Timolol)
- Drug of choice of posterior uveitis caused by CMV: Ganciclovir
- Treatment of choice of posterior uveitis caused by toxoplasma: Triple therapy (Steroid + Sulfasalazine + Pyrimethamine)
- Drug of choice of toxoplasma uveitis in pregnancy: Spiramycin

- MC complication of anterior uveitis/ iridocyclitis: Secondary open angle glaucoma
- MC complication of recurrent anterior uveitis: Cataract
- MC cause of complicated cataract: Chronic iridocyclitis
- Retinal detachment is not a complication of acute anterior uveitis.
