[Cavernous hemangioma of the optical canal and superior palpebral fissure].

The paper describes a rare case of cavernous hemangioma spreading to the optical canal and superior palpebral fissure. The distinctive feature of the case is the location of cavernous hemangioma in anterior two thirds of the optical canal and superior palpebral fissure. In this connection, despite small sizes of a neoplasm, it caused a significant decrease in visual function during 10 months. The first sign of the disease within 10 months before surgery was periodic diplopia, which served as an indication for magnetic resonance imaging that revealed a pathological process and a correction decision was taken to follow up the patient due to visual preservation. Worse vision served as an indication for surgery as further follow-up might result in irreversible sequels. Undertaken active policy proved its worth despite its risk. The used respective supraorbital access permitted radical removal of a neoplasm to recover visual functions.
