OBJECTIVE: A female @entity1 , resident in the state of Colorado, presented with @entity735 . Slit-lamp examination showed the presence of a thin, threadlike worm entwined in the @entity267 . The @entity1 was taken to surgery for removal of the parasite. DESIGN: A case report. INTERVENTION: A 3-mm-long supertemporal incision was made in the @entity267 and further dissected until the worm could be grasped and removed by gentle traction. RESULTS: The worm, a filarial @entity2199 , was identified as a member of the genus Onchocerca, most likely Onchocerca cervicalis, a natural parasite of @entity1641 . The @entity1 had an uneventful recovery, and 1 week after surgery, her visual acuity, intraocular pressure, and @entity3279 were all resolving. CONCLUSION: In the United States and elsewhere, most cases of zoonotic filarial infection involving the eye are caused by Dirofilaria or @entity7399 -like worms. However, the current case was caused by a species of Onchocerca. This is the first case of zoonotic Onchocerca from the eye to be reported, only the second case of zoonotic Onchocerca in the United States, and the seventh case worldwide. The worm was removed surgically, and the @entity1 had an uneventful recovery.
