1.What is orbital cavernous hemangioma? Orbital cavernous hemangioma is actually a kind of vascular malformation, because it looks like a sponge when cut, so it is named “cavernous hemangioma”, but it is not a real tumor. 2.What are the symptoms of cavernous hemangioma? It depends on its location and size. If it is located at the tip of the orbit, that is, the place where the brain is connected, it is easy to compress the optic nerve and cause vision loss. If it grows to a large size, it will slowly push the eyeball forward, causing the eyeball to protrude and shift. 3.Is cavernous hemangioma benign or malignant? Yes, it is benign. 4.How to treat cavernous hemangioma? Surgery. 5.Will the surgery leave scars? Generally, the approach is through the conjunctiva, which can not be seen outside the eyelid. 6.Will cavernous hemangioma recur after surgery? No, it will not.
