This image appears to depict a severe case of parasitic infestation, possibly caused by Loa loa, commonly known as the African eye worm. This condition is caused by a parasitic nematode transmitted to humans through the bite of deerflies (genus Chrysops), which are prevalent in certain tropical regions of Africa.

Once inside the human body, the parasite migrates through subcutaneous tissues and can occasionally be seen crossing the eye, causing significant discomfort, redness, swelling, and itching. While the presence of the worm in the eye can be alarming, it is not typically life-threatening but requires immediate medical intervention.

Treatment usually involves antiparasitic medications like diethylcarbamazine (DEC) to kill the adult worms, though surgical removal may be necessary if the worm is visible and causing extreme discomfort. This condition highlights the importance of protective measures, such as wearing insect repellent and appropriate clothing, when traveling or living in endemic areas.

If you or someone you know experiences symptoms like these after traveling to a high-risk region, consult a healthcare professional immediately for diagnosis and treatment.
