H06: Disorders of lacrimal system and orbit in diseases classified elsewhere

"Disorders of the lacrimal system and orbit in diseases classified elsewhere" refers to a group of medical conditions that primarily affect your tear production system (lacrimal system) and the region surrounding your eye (orbit). Typical issues can arise due to diseases categorized under different medical classifications. For instance, an autoimmune disease might cause inflammation or blockages in the tear ducts, interrupting normal tear flow leading to dryness or excessive tearing. Additionally, conditions like orbital cellulitis or pseudotumor, caused by infections or other diseases, can lead to painful swelling or pressure in the eye region. Symptoms depend on the specific affliction but may include redness, discomfort, eye irritation or drainage, blurred vision, or even vision loss. The progression of these disorders can vary considerably, from mild, transient effects to serious, potentially permanent eye damage.
