H02.85

Clinical Causes: Lymphatic filariasis caused by parasitic worms such as Wuchereria bancrofti, Brugia malayi, and Brugia timori Chronic lymphatic obstruction due to repeated infections or inflammation Blockage of lymphatic vessels from trauma or previous surgeries Additionally, non-parasitic causes such as congenital lymphatic malformations, although less common, can lead to eyelid swelling resembling elephantiasis

Key Symptoms: Progressive swelling of the eyelid that may become hard and thickened over time Skin discoloration, often darkening or hyperpigmentation Persistent or recurrent infections of the eyelid area Impaired eyelid movement or closure due to the enlargement Possible visual disturbances if the swelling obstructs vision Discomfort or sensation of heaviness in the affected eyelid

Diagnosis Path: Microscopic identification of microfilariae in blood samples, typically collected at night when they are most active Serological tests to detect filarial antigens or antibodies Imaging studies such as ultrasound or lymphoscintigraphy to evaluate lymphatic flow and identify obstructions Skin biopsy might be considered in atypical cases to assess tissue morphology and rule out other causes of swelling

Treatment Protocols: Antiparasitic medications like diethylcarbamazine (DEC), ivermectin, or albendazole to eliminate parasites in parasitic cases Management of secondary infections with antibiotics Lymphatic drainage techniques, such as manual lymphatic drainage therapy, to promote lymph flow Surgical interventions to remove excess tissue or correct deformities, especially when swelling is severe or causes functional issues Supportive care with compression therapy or skin care to prevent infections and improve skin condition In some cases, reconstructive surgery or eyelid reconstruction may be necessary to restore function and appearance
