Jennifer Hsieh Psy 159 Physiological Basis of Perception 1/11/2005. General Anatomy of the Eye & Degenerative Diseases of Human Retina . Background. Key Terms. Vitreous humor – fluid in major chamber of eye. Retina – encodes the info as a neural signal to transmit to the brain.
Physiological Basis of Perception
Photoreceptors (Rods and Cones)
Outer Plexiform Layer
Inner Nuclear Layer
Inner Plexiform Layer
Age related macular degeneration - the macular area and fovea become compromised due to the pigment epithelium behind the retina degenerating and forming white spots.
Glaucoma - the pressure within the eye becomes elevated. The pressure rises because the anterior chamber of the eye cannot exchange fluid properly by the normal aqueous outflow methods.
Retinits pigmentosa - a hereditary disease of the retina. Most of the faulty genes affect the rod photoreceptors. Characteristic pathology is the occurrence of black pigment in the peripheral retina and thinned blood vessels.
Diabetic retinopathy - a side effect of diabetes that can cause blindness. The vital nourishing blood vessels of the eye become damaged, distorted and multiply in uncontrollable ways.
B. Healthy Eye (Normal)
C. Macular degeneration
