[|Human|] I had an MRI of brain and orbits that indicated a meningioma behind the right orbit. This has caused my vision to go from 20/40 to 20/100 in 6 months. Wondering if surgery to remove the tumor would allow my vision to return to normal. YYYY@YYYY
[|AI|]  Hello. I have been through your question and understand your concern. Meningiomas of the orbit are benign conditions, but carry the risk of compressing the optic nerve causing decreasing the visual acuity, like in your case. If such eventuality is progressing, then there is a clear indication of surgery to remove the meningioma. Maybe the vision in your right eye will not return completely normal, but for sure it will not get worse, which seems a concrete possibility if left untreated. I definitely recommend the surgery at this point. Hope this helps, please feel free using MHC for further questions
