Eyeworm (African eyeworm)

Found primarily in West and Central Africa; lives in human subcutaneous tissue and can migrate across the subconjunctiva of the eye.

Absorbs nutrients from the host's body fluids while residing in subcutaneous tissues.

Transmitted by deer fly bites (Chrysops species); the larvae mature into adults in human tissue and crawl beneath the skin or across the eye's surface.

Causes loiasis, leading to localized 'Calabar swellings,' itching, and eye irritation; surgical removal from the eye is often required to prevent discomfort and damage.
