Retinal Diseases – Solutions for Your Retina in a Kuwait Hospital PowerPoint PPT Presentation

Retinal Diseases – Solutions for Your Retina in a Kuwait Hospital - An eye healthcare facility defines the retina as the innermost light-sensitive membrane covering the back wall of the eyeball. When light strikes the retina, photoreceptors transform the light into electrical signals. The electrical signals go from your retina to your brain via the optic nerve.
