Onchocerciasis is a form of filariasis, caused by the parasitic worm Onchocerca volvulus, transmitted by the black fly. The infection can either be asymptomatic or manifest as an ocular disease (river blindness) with itchy eyes, erythema, photophobia, onchodermatitis or onchocercal skin disease (classified into acute papular, chronic papular, lichenified, atrophic, and depigmentated) and onchocercomas (over bony prominences). Other classic clinical manifestations are ichthyosis-like lesions (''lizard skin'') and ''hanging groin'', which may be associated with lymphadenopathy.
Biomarker and diagnostic research for onchocerciasis has been reported in the published literature.
1 FDA-approved treatment is available for onchocerciasis, including MOXIDECTIN (MOXIDECTIN, approved 2018). An additional 2 compounds hold orphan drug designation.
