Seeing stars

I've had occurences of tiny "pinhole" lights in my vision coming over the top of my head, lots of them. Who should I see, a nuerologist? I was diagnosed with a very small tumor on my pineal gland, could this be it?

A visit to a neurologist is a good idea, especially if the lights are a new development. Pineal tumors may cause visual hallucinations, but visual disturbances can occur from a variety of other things. If this is a new development, something has changed, so the tumor could be growing or something else may show up.
