[Retinal hemorrhages after ivermectin treatment for onchocerciasis in a patient with Loa loa microfilaremia]. / Survenue d'hémorragies rétiniennes lors du traitement de l'onchocercose par l'ivermectine chez une patiente co-infectée par la loase.

A case of retinal hemorrhages with special features and degradation of the general condition is reported in a 27-year-old female patient, following the ingestion of ivermectin for the treatment of onchocerciasis. The patient was infested by both Onchocerca volvulus and Loa loa. A bilateral peripheral temporal location of the retinal lesions was observed. The role of L. loa microfilarial load in the occurrence of the retinal lesions as well as the transient character of the lesions are discussed, based on the clinical observation and with reference to the literature. The authors call for setting up a rapid therapeutic system to take care of serious adverse reactions following treatment with ivermectin in areas with a high prevalence of L. loa infestation.
