Optic nerve edema, generally referred to as optic nerve papillary edema, is a non-inflammatory obstructive edema of the optic papilla. The etiology is mostly caused by systemic diseases. It may also be related to increased intracranial pressure, increased intraorbital pressure and decreased intraocular pressure.
1. Systemic diseases: common diseases include leukemia, anemia, nephritis, etc., which may cause symptoms of optic nerve papillary edema.
2. Increased intracranial pressure: intracranial space-occupying lesions such as cerebral hemorrhage, brain tumor, brain abscess, etc., or increased cerebrospinal fluid in intracranial infections, traumatic brain injury, hydrocephalus, etc., which conveys the intracranial pressure to the subarachnoid space and affects the venous reflux of the retina, thus leading to optic nerve papilledema.
3. Increased intraorbital pressure: intraorbital tumor, abscess, orbital cellulitis, etc., can compress the optic nerve and lead to optic nerve papilledema.
4. Decrease in intraocular pressure: corneal fistula, anti-glaucoma surgery, etc., can lead to intracranial pressure is relatively higher than the intraocular pressure, which can cause optic nerve papillae edema.
When optic nerve papilloedema occurs, you should go to the hospital in time, complete the relevant examination, the doctor will clarify the cause of the disease, and then follow the doctor’s instructions for standardized treatment.
