B73.01
Onchocerciasis with endophthalmitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Onchocerciasis, commonly known as river blindness, is a parasitic disease caused by the filarial worm Onchocerca volvulus. When the infection affects the eye, leading to inflammation of the internal eye structures, it is termed onchocerciasis with endophthalmitis. This condition can result in significant visual impairment if not diagnosed and managed promptly. The ICD-10 code B73.01 specifically refers to cases where onchocerciasis is present along with endophthalmitis, indicating a serious ocular complication of the infection.
Causes & Symptoms
Clinical Causes: Infection with the parasitic worm Onchocerca volvulus, transmitted through repeated bites from infected blackflies (Simulium species). Prolonged exposure to blackflies in endemic areas, typically near rivers and streams. Inadequate preventive measures in regions with high vector populations.
Key Symptoms: Visual disturbances such as blurred vision or seeing floaters. Eye redness and swelling. Pain around or inside the eyes. Photophobia, or sensitivity to light. Swelling of the eyelids. In advanced stages, optic nerve damage leading to partial or complete vision loss. Possible presence of nodules under the skin, especially near the head or neck.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of patient history, clinical examination, and laboratory tests. Key diagnostic steps include:
Treatment Protocols: Treatment aims to eliminate the parasite, reduce symptoms, and prevent further damage. Common approaches include:
