Hello, Welcome to Health Care Magic. I have gone through your query and I understand your concern. In order to be more helpful for your friends case, I would need more details, like for example the symptoms your friend is suffering from. As a first impression from the details you are giving, I would suspect for a loa loa filariasis, but, I cannot give any diagnosis or treatment without other details. I would recommend that your friend visits his/her local infectionist, in order to have a clear diagnosis. After that I could help you with an option of treatment. If the disease I mentioned above is diagnosed, it could be treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunct. Hope I answered to your question. Take care. Kind Regards, Dr. Ina Zaimi
