We report on two cases of dirofilaria involving the orbit. There have been no previous case reports of superior rectus involvement in the literature.
The presenting history, ocular examination, relevant investigations and treatments are discussed.
In both cases the lesion was debulked surgically with subsequent histopathological identification of a dirofilarial worm. Postoperatively both patients were relieved of their presenting symptoms with no recurrence of the lesion.
Dirofilarial involvement of the orbit is uncommon. It should be considered as a rare infectious form of specific orbital inflammation and considered in the differential diagnosis of orbital inflammatory lesions.
