Vasculitis is a heterogeneous group of diseases that implies the presence of necrosis and inflammation in the walls of blood vessels. The mechanisms involved are the following: immune complexes, endothelial cell antibodies, and anti-lysosomal antibodies. The immune reactions can be triggered by these mechanisms: immune complexes, endothelial cell antibodies, and anti-lysosomal antibodies. Antineutrophil cytoplasmic antibodies (ANCA) have an essential role in the following so-called ANCA+ vasculitis. Regarding this issue, we proposed to present the various aspects of ocular involvement in the ANCA+ vasculitis.

We are presenting the case of a patient who was clinically diagnosed with subconjunctival ocular dirofilariasis, confirmed by the parasitological examination. The treatment consisted in the surgical extraction of the parasite, a local treatment with antibiotics and steroidal anti-inflammatory mydriatic and general treatment with antihelminthic, antibiotic, analgesic, and anti-inflammatory drugs. The intraoperative and postoperative evolution of the case was favorable.
