This was tested in people. That is the most reliable kind of research we share.
This was a look back at records of people who already had surgery, not a trial.
The short version
People whose sight was normal before surgery most often still had normal sight after.
What was studied. Doctors looked back at the records of 146 people who had surgery for a skull base meningioma. These tumors touched or pressed on the nerves that carry sight.
What they found. The team matched 48 pairs of people so the two groups were alike. Among those with normal sight before surgery, 95.8% had normal sight after. Among those with sight problems before surgery, only 31.3% ended up with normal sight.
What this means, and what it doesn't
What it could mean: Sight before surgery may say a lot about sight after. If your sight is still normal, it is likely to stay that way. If sight is already harmed, it may not come all the way back. The size and spot of the tumor matter too, so this is one thing to weigh with your own doctor.
What it doesn't mean: This does not show that earlier surgery saves sight. The authors say that plainly. It was a look back at old records, not a planned trial in people. It does not tell doctors the best time to operate. It is not a cure, and it does not change care on its own.
