H03: Disorders of eyelid in diseases classified elsewhere

Disorders of the eyelid in diseases classified elsewhere is a group of conditions, where the primary disease or disorder is not specifically focused on the eyelid, but they manifest eyelid-related issues as part of their symptoms or complications. These disorders can result from a wide range of underlying conditions, including systemic diseases, infections, inflammatory conditions, or even neurological illnesses. Symptoms commonly include eyelid swelling, redness, pain, dryness, or sagging. The eyelid's function in protecting the eye can be compromised due to these disorders, affecting blink reflex, tear film distribution, and potentially threaten the health of the eye. The progression of these disorders largely depends on the nature and severity of the underlying disease. Certain disorders may present acutely while others may evolve gradually over time. Treatment of these conditions tends to target the underlying disease to alleviate symptoms or complications affecting the eyelid.
