Cavernous haemangioma of the orbit.

Cavernous haemangioma is considered the most common primary orbital tumour. We present three cases of cavernous haemangioma of the orbit presenting with deterioration of vision and painless unilateral exophthalmos. A review of the current literature available is compared with our findings. The diagnostic examinations that are most helpful in deciding that an orbital cavernous haemangioma is present include plain film X-ray examination of the orbits and sinuses, B-mode ultrasonography and computerized axial tomography. Each patient underwent a transcranial surgical procedure for removal of the tumour, after pre-operative evaluation.
