Symptoms include photophobia, redness, watering of the eyes, lacrimation, constriction of the pupil, and blurred vision. Iridocyclitis is usually caused by direct exposure of the eyes to chemicals, particularly lacrimators . It can be effectively treated with tropane alkaloids or steroids.
There are six classifications of iridocyclitis.
- Acute: sudden symptomatic onset, lasting no more than six weeks.
- Chronic: Persisting for more than six weeks, possibly asymptomatic. Chronic iridocyclitis is usually associated with systemic disorders including ankylosing spondylitis, Behçet's syndrome , inflammatory bowel disease, juvenile rheumatoid arthritis , Reiter's syndrome, sarcoidosis, syphilis, tuberculosis, and Lyme disease.
- Exogenous: related to external damage to the uvea or invasion of external microbes.
- Endogenous: related to internal microbes.
Granulomatous or Non-granulomatous
- Granulomatous: accompanied by large keratotic precipitates.
- Non-granulomatous: accompanied by smaller keratotic precipitates.
To immobilize the iris and decrease pain, one may find tropane alkaloids effective, particularly scopolamine and atropine in .25% and 1% concentrations respectively. Topical steroids may be used to decrease inflammation, particularly prednisolone and dexamethasone.
