Upper left: series of fine translucent larvae  seen in cornea

Upper right: whitish starburst infiltrate around dead microfilaria; we believe they are protected from host immune system by biofilm when alive, but if they are not ingested by Simulium within a few months, they die and lose biofilm, causing immune infiltrate reaction.

Lower left shows corneal scarring at medial and lateral aspects of cornea, characteristic pattern of early disease

Lower right shows three small infiltrates or scars from deceased microfilariae
