H44.312

Clinical Causes: Prolonged contact with copper-containing intraocular foreign bodies, such as broken surgical instruments or metallic fragments introduced into the eye Occupational exposure to copper dust or fumes in industries like mining, metalworking, or electronics manufacturing Use of copper-containing eye drops or contact lenses that are contaminated or improperly used Inherited or metabolic disorders leading to abnormal copper accumulation in tissues Inadvertent insertion of copper devices or materials during ophthalmic procedures

Key Symptoms: Visual disturbances, including blurred vision or visual acuity changes Presence of brownish or greenish deposits on the cornea or within the eye tissues Discoloration of the sclera or inner eye structures Photophobia or sensitivity to light Eye pain or a sensation of foreign body sensation Potential decrease in eye mobility or discomfort during eye movement In advanced cases, pigmentation may affect the retina, leading to further visual impairment

Diagnosis Path: Detailed medical history focusing on occupational exposure or previous ocular injuries Slit-lamp examination to observe deposits and tissue discoloration Fundoscopy to examine the retina and inner eye structures Imaging studies like X-rays or CT scans to detect intraocular metallic foreign bodies Laboratory tests such as conjunctival or iris biopsy, if necessary, to assess copper deposits Copper level tests in blood or ocular tissues in atypical or systemic cases

Treatment Protocols: Surgical removal of intraocular copper foreign bodies to halt further copper deposition Managing inflammation or tissue reaction with appropriate medications, such as corticosteroids Monitoring for and treating secondary complications like glaucoma or retinal degeneration Use of chelating agents in systemic cases to reduce copper levels, though this is less common for localized ocular chalcosis Regular follow-up to assess visual function and monitor for progression or recurrence
