Brief 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).

Outcome Measures
Primary Outcomes (2)
Number of participants with complete microfilaria clearance from the eye at 3 months
Microfilaria in the anterior chamber of the eye will be counted during slit lamp examination at time of assessment. Participants without Mf in the eye will be considered clear of infection in the eye.
3 months following treatment
Number of participants with complete microfilaria clearance from the eye at 6 months
Microfilaria in the anterior chamber of the eye will be counted during slit lamp examination at time of assessment. Participants without Mf in the eye will be considered clear of infection in the eye.
6 months following treatment
Secondary Outcomes (6)
The change from baseline in the number of microfilaria detected in the skin at 3 months
baseline, and 3 months following treatment
The change from baseline in the number of microfilaria detected in the skin at 6 months
baseline, and 6 months following treatment
The change from baseline in the number of microfilaria detected in the eye at 3 months
baseline, 3 months following treatment
The change from baseline in the number of microfilaria detected in the eye at 6 months

- +1 more secondary outcomes
Other Outcomes (3)
Assess the utility of optical coherence tomography for evaluating the presence and clearance of Mf in the anterior and posterior segments of the eye.
baseline, 3 and 6 months following treatment
