Retinal diseases vary widely, but most of them cause visual symptoms.
Retinal diseases can affect any part of your retina, a thin layer of tissue on
the inside back wall of your eye. The retina contains millions of
light-sensitive cells (rods and cones) and other nerve cells that receive and
organize visual information. Your retina sends this information to your brain
through your optic nerve, enabling you to see.
Common retinal diseases are given below
Seeing floating specks or cobwebs
Blurred or distorted (straight lines look wavy) vision
