Season 2, Episode 20: Eyes

Vision is the dominant of the five senses the body uses to interpret its surroundings. The organ of vision is the eye which is composed of a series of lenses and spaces that give focus to images, just as a camera does. It is composed of the cornea, lens, and the aqueous and vitreous humor, each of which contribute to perfecting the focus of the light received by the retina, analogous to the film of the camera.  Given how critical the eye is to the understanding of our surroundings, it is heavily protected by a bony orbit and allowed near omni-directional movement made possible by six eye muscles and three of the 12 cranial nerves.  Vision can be disturbed if the light can’t be focused, if the retina can’t receive the light, if the optical nerve is impaired, or if the eye muscles cannot move synchronously. All of which require an intact blood supply and orbit.  On this episode , we'll be joined by Dr. Joseph Hyatt, an ophthalmologist and eye specialist, as we talk to callers about varied issues impairing their vision.
