Season 3, Episode 12: Turning Light Into Sight

The eye's posterior chamber, from the back of the lens through the gel-like vitreous humor to the retina’s neural network and blood vessels, is a marvel of biologic engineering. It translates light into electrical impulses, enabling vision. Age and disease not only produce benign flashers and floaters but also the more serious vitreous and retinal detachment. They also contribute to macular degeneration and proliferative retinopathy. All of these conditions once resulted in blindness, but today’s intraocular lasers and vascular growth factor inhibitor injections can preserve a patient’s vision. We take a closer look at all of the above on this episode.
