---|
Iridocyclitis, a type of anterior uveitis, is a condition in which the uvea of the eye is inflamed.
Iridocyclitis is Inflammation of the iris and the ciliary body.
Symptoms
Symptoms include:
- Photophobia
- Redness
- Watering of the eyes
- Lacrimation
- Miosis, constriction of the pupil
- Blurred vision
- Synechia
Causes
Iridocyclitis is usually caused by direct exposure of the eyes to chemicals, particularly lachrymators, but can also be caused by ocular viral infection such as herpes zoster (i.e. herpetic iridocyclitis).
Can also be associated with juvenile idiopathic arthritis (also known as juvenile rheumatoid arthritis). Seen usually with the pauciarticular type in females but polyarticular types are also at risk.
Types
There are six classifications of iridocyclitis.
Acute or chronic
- 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 or endogenous
- 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 keratic precipitates
- Non-granulomatous
- Accompanied by smaller keratic precipitates
Treatment
Iridocyclitis can be effectively treated with tropane alkaloids or steroids.
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. Upon presentation of a severe case, a subconjunctival steroid injection may be administered.
