Projection of the left eyeball and normal right eyeball are usually caused by hematoma formation in the left eye socket, cellulitis of the left eye socket, or orbital space-occupying lesions.
1. Hematoma: It is usually caused by the rupture of small blood vessels in the orbit due to trauma or abnormal coagulation function, etc. The bleeding will be pooled in the orbit, which will increase the volume of orbital contents and push the eyeball to protrude.
2. Orbital cellulitis: caused by trauma to the orbit or low immunity leading to soft tissue infection in the orbit. Inflammation caused by infection will lead to edema of orbital contents and push out the eyeball.
3. Orbital space-occupying lesions: inflammatory pseudotumor, orbital hemangioma, etc. With the gradual growth of the lesion, the volume increases, which will also push the eyeball protruding.
If the left eyeball protrudes, you should go to the hospital for examination in time, such as orbital CT examination, orbital ultrasound examination, etc. to make a clear diagnosis, and be treated under the guidance of the doctor.
