There are many types of left orbital space-occupying lesions, some of which are not serious, but if the space-occupying is obvious, or malignant lesions are more serious, which may affect vision, eye movement and so on.
1. If the occupying position of some patients is not obvious, such as inflammatory pseudotumor, hemangioma, etc., the tumor is small, or the lesion is eliminated after timely treatment, which usually will not cause serious consequences.
2. Some patients with obvious or malignant lesions will be more serious.
As the orbital volume is relatively small, there are a large number of nerves and blood vessels traveling inside, such as optic nerve, motor nerve, abducens nerve, buccal nerve, trigeminal nerve, supraocular artery, infraocular artery, etc. If the occupying lesion squeezes the eye, it will not cause serious consequences. If the occupying lesion squeezes or invades the above important structures, it may cause serious symptoms, such as vision loss, visual field defect, and limitation of eye movement.
3. For malignant tumors among intraorbital tumors, they may also invade into the skull along the optic nerve canal and other structures, which may even be life-threatening in the most serious cases.
Therefore, patients with intraorbital space-occupying lesions must consult the doctor in time and get treatment as soon as possible, and usually surgery is needed to remove them.
