Ruzutti’s corneal light reflex seen in keratoconus (Video)
length: 19 seconds
This video shows what the ruzutti’s light reflex looks like in eyes with keratoconus. You perform this test by shining a penlight into the eye at an oblique angle. The cone shape of the cornea causes the resulting iris light reflection to a point. This is hard to explain, so you should check out the video.
Other exam findings of keratoconus include Munson’s sign (notching of the lower eyelid when looking down) and a Fleischer ring (a corneal iron line around the base of the cone).

Great video, I have read about this sign but I did not understand how it was obtained. Thanks to you, a master in slit lamp, I finally understand it. Very best regards, thanks so much for your great videos y tips.
