Ocular Changes After Ivermectin - (DOLF IVM/Oncho)

Summary

The DOLF Ocular Changes after Ivermectin study will investigate the kinetics of O. volvulus microfilaria (Mf) in the eye following treatment with ivermectin. The primary objective is to determine the proportion of participants with complete Mf clearance from the eye at 3 and 6 months following treatment with ivermectin (IVM).
