Optic nerve injuries occur when the optic nerve, which transmits visual information from the eye to the brain, is damaged. This can result from trauma, tumors, or diseases like multiple sclerosis. Symptoms may include vision loss, blurred vision, or changes in color perception, depending on the severity and location of the injury. Diagnosis typically involves a comprehensive eye examination and imaging tests, such as MRI or CT scans. Treatment options vary based on the cause and extent of the injury, ranging from medications to manage inflammation to surgical interventions in some cases. Early detection is crucial for improving outcomes.
