H21.2
Degeneration of iris and ciliary body
Clinical Classification Guidelines
Medical Intelligence & Overview
Degeneration of the iris and ciliary body, classified under ICD-10 code H21.2, refers to a progressive deterioration of these essential structures within the eye. The iris is the colored part of the eye that controls the amount of light entering by adjusting the size of the pupil, while the ciliary body plays a crucial role in focusing the lens and producing aqueous humor, which nourishes the eye. This degeneration can lead to vision problems and other ocular complications, making understanding this condition important for early recognition and management.
Causes & Symptoms
Clinical Causes: Aging: Natural age-related changes can lead to degenerative alterations in eye tissues. Inflammatory conditions: Chronic uveitis or other inflammation may damage the iris and ciliary body. Genetic factors: Some hereditary conditions may predispose individuals to tissue degeneration. Trauma: Eye injuries can accelerate deterioration or cause structural changes. Systemic diseases: Conditions like diabetes or autoimmune disorders can impact eye health. Previous eye surgeries: Certain procedures may influence the structural integrity of these eye parts. Exposure to toxins or harmful chemicals: Environmental factors can contribute to tissue degradation.
Key Symptoms: Gradual loss of visual acuity: Blurred or dim vision developing over time. Photophobia: Increased sensitivity to light due to changes in iris function. Reduced pupil responsiveness: Difficulty adjusting to different lighting conditions. Discoloration or irregularities in the iris: Changes in eye appearance. Eye discomfort or pain: Often associated with underlying inflammation. Visual disturbances: Such as halos or glare around lights. Possible ocular redness or swelling in early stages.
Diagnostic & Treatment
Diagnosis Path: Visual acuity testing to assess clarity of vision. Slit-lamp examination to observe the internal structures of the eye. Assessment of the iris and ciliary body for signs of degeneration, irregularities, or inflammation. Intraocular pressure measurement to rule out associated conditions like glaucoma. Imaging techniques such as ultrasound biomicroscopy (UBM) or anterior segment OCT for detailed structural analysis. Refraction tests to determine the effect on vision.
Treatment Protocols: Anti-inflammatory medications: Such as corticosteroids to control inflammation. Pupil-modulating drugs: To improve iris function or manage light sensitivity. Surgical interventions: In severe cases, procedures may be needed to repair or replace damaged tissue. Corrective lenses: To assist with visual deficits caused by structural changes. Management of underlying conditions: Controlling systemic diseases or addressing inflammation can slow degeneration. Regular monitoring: Frequent eye exams to assess progression and adjust treatment plans.
