This is a report about spotting a tumor, not a new treatment.
The short version
A tumor on the nerve to the eye was first thought to be simple swelling.
What was studied. This is a report on a tumor called an optic nerve sheath meningioma. It grows on the covering of the nerve that runs from the eye to the brain.
What they found. The full report was not available, so the details are not known here. The title says this tumor acted like optic perineuritis. That is swelling around the eye nerve. The title also says steroids fooled the doctors.
What this means, and what it doesn't
What it could mean: Eye nerve trouble that gets better with steroids may not be simple swelling. A tumor can act the same way at first. It can help to keep checking with your care team, even when steroids seem to help.
What it doesn't mean: This does not mean steroids treat this kind of tumor. It is not a cure and it is not a new treatment. This is one report about how a tumor can be mistaken for something else. It does not tell you what your own scans mean. Only your care team can say that.
