WHAT: Iridocyclitis. Iridocyclitis: the inflammation of the anterior uveal tract, which is composed of the iris and the ciliary body WHY: Iridocyclitis may be one of the signs of juvenile rheumatoid arthritis (especially of pauciarticular onset), ankylosing spondylitis, Reiter\'s syndrome, or sarcoidosis. HOW: Iridocyclitis may be asymptomatic or symptomatic. In the asymptomatic form, which is usually seen in juvenile rheumatoid arthritis, the onset is insidious and the physical findings minimal initially. A slit lamp examination is often required at this time and will show clumps of white blood cells in the anterior chamber and small white precipitates with or without flecks of fibrin on the posterior surface of the cornea. The patient may develop an irregular pupil if adhesions develop between the iris and the capsule of the lens. Later on, cataracts, glaucoma, band keratopathy or phthisis bulbi may develop (see sequelae of iridocyclitis). The symptomatic form usually presents acutely with eye pain, photophobia, or blurred vision. The pupil is small and responds poorly to light. There is a circumcorneal flush secondary to dilated limbal vessels. All the findings seen in asymptomatic iridocyclitis may be found with slit lamp examination.
