A18.54
Tuberculous iridocyclitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Tuberculous iridocyclitis is an inflammation of the iris and ciliary body caused by tuberculosis bacteria. This condition results from a secondary infection due to tuberculosis, affecting the eye's interior structures. It is a rare form of ocular tuberculosis that can impair vision if not diagnosed and treated promptly. Recognizing the symptoms early and understanding its causes can help in managing this condition effectively.
Causes & Symptoms
Clinical Causes: Mycobacterium tuberculosis infection spreading to the eye Hematogenous spread from a primary tuberculosis site Reactivation of latent tuberculosis bacteria within ocular tissues Immune response to the tuberculosis bacteria leading to inflammation
Key Symptoms: Eye redness and swelling Sensitivity to light (photophobia) Decreased or blurred vision Eye pain or discomfort Floaters or spots in the vision Iridocyclitis signs such as constricted pupil and keratic precipitates
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of medical history, eye examination, and laboratory tests. An ophthalmologist may observe signs of inflammation in the anterior chamber of the eye. Additional diagnostics may include tuberculin skin test (Mantoux test), interferon-gamma release assays, chest X-rays, and laboratory analysis of ocular fluids to detect tuberculosis bacteria. Imaging studies, like ultrasound or ocular coherence tomography (OCT), can also assist in assessing eye involvement.
Treatment Protocols: Treatment primarily consists of anti-tuberculosis therapy, typically a combination of antibiotics over several months to eradicate the bacteria. Corticosteroids may be prescribed to reduce inflammation and prevent tissue damage. Regular follow-up with an ophthalmologist is essential to monitor treatment response and adjust medications if necessary. Managing intraocular pressure and preventing complications like cataracts or glaucoma are also important aspects of care.
