Below is a retinal tear discovered on routine eye dilation. The arrow points to the tear which, in 3 dimensions, comes out into the vitreous cavity of the eye. The dark area just above it is actually the shadow of the operculum. Retinal tears eventually cause retina detachments. This can lead to complete and irreversible blindness if not caught in time. This patient had no symptoms.
Every week I catch someone with a retinal tear who had no symptoms. We can only catch these when we dilate the eye. Dilation is no extra charge at Sonoran Desert Eye Center.
