This fundo-scope image was taken during a practice session, because we asked for it. We tried to use a slit lamp to visualize retina, but retina is visible only in a slit-lamp lighted area only. I was wondering how we can see a retina image like in a textbook.

This is a very healthy normal retina from one of our students.
Optic disk, cup-disk ratio, macula, vessels, all healthy.
thick vessels are vein, and the other are artery.
