Purpose:
We report on two cases of dirofilaria involving the orbit. There have been no previous case reports of superior rectus involvement in the literature.
Methods:
The presenting history, ocular examination, relevant investigations and treatments are discussed.
Results:
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.
Conclusions:
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.
