H20.0

Clinical Causes: Autoimmune disorders like rheumatoid arthritis or HLA-B27 related conditions Infections caused by viruses (herpes simplex, varicella-zoster), bacteria, or parasites Ocular trauma or injury Presence of systemic inflammatory diseases such as sarcoidosis or juvenile idiopathic arthritis Exposure to certain drugs or toxins Unknown factors in some cases (idiopathic)

Key Symptoms: Eye redness, often concentrated around the iris Eye pain or tenderness Sensitivity to light (photophobia) Blurred vision or decreased visual acuity Small or irregular pupil size Tearing and watery eyes Possible presence of floaters or visual disturbances Discomfort that worsens with eye movement or exposure to bright light

Diagnosis Path: Diagnosis involves a comprehensive eye examination by an ophthalmologist, including slit-lamp biomicroscopy to observe inflammation in the anterior chamber. Additional tests such as eye pressure measurement, retinal examination, blood tests, or imaging may be performed to identify underlying causes or associated systemic conditions. The ophthalmologist assesses symptoms, visual acuity, and the presence of characteristic signs to confirm the diagnosis.

Treatment Protocols: Management of acute and subacute iridocyclitis typically includes the use of corticosteroid eye drops to reduce inflammation and improve symptoms. Dilating eye drops may be prescribed to ease discomfort and prevent the formation of synechiae (adhesions between iris and cornea). Addressing underlying causes, such as infections or systemic illnesses, is essential. Regular follow-up appointments are necessary to monitor response to treatment and prevent complications, including increased eye pressure or glaucoma. In some cases, additional immunosuppressive medications may be indicated for chronic or recurrent inflammation.
