H21.501

Unspecified adhesions of iris, right eye

Clinical Classification Guidelines

Medical Intelligence & Overview

Unspecified adhesions of the iris in the right eye refer to abnormal attachments that form between the iris—the colored part of the eye—and other structures within the eye. These adhesions can affect the eye's appearance and function, potentially leading to visual disturbances. The ICD-10 code H21.501 is used when specific details about the adhesions are not documented, indicating an unspecified state of iris adhesion in the right eye. While sometimes, iris adhesions occur without symptoms, they can also cause issues such as decreased vision or increased eye pressure. Proper diagnosis and management are important to address any visual or ocular health concerns.

Causes & Symptoms

Clinical Causes: Previous eye injuries or trauma Inflammation of the eye, such as uveitis Post-surgical changes following eye procedures Congenital factors present from birth Ocular infections Certain systemic diseases that affect eye tissues

Key Symptoms: Visual disturbances, such as blurred vision Unequal pupil size or shape Increased sensitivity to light (photophobia) Eye redness or discomfort Possible eye pain or pressure Appearance of irregular or abnormal iris shape

Diagnostic & Treatment

Diagnosis Path: Diagnosis of iris adhesions involves a comprehensive eye examination by an ophthalmologist. Key diagnostic procedures include slit-lamp biomicroscopy, which allows detailed visualization of the iris and its attachments. The ophthalmologist may also perform tests to assess visual acuity, pupil response, and eye pressure to evaluate the extent of any functional impairment. An ophthalmic examination helps determine whether the adhesions are causing complications or if further investigations are necessary.

Treatment Protocols: Treatment options depend on the severity and impact of the iris adhesions. In many cases, if the adhesions are not causing significant symptoms or visual impairment, careful observation may be sufficient. When intervention is needed, possible treatments include:
