Retina Disorders during Glaucoma

The cornea and point of convergence focus light onto the retina, the clear, light-sensitive structure at the back of the eye. The central zone of the retina, called the macula, contains a high thickness of shading delicate photoreceptor (light-recognizing) cells. These telephones, called cones, make the most sharpened visual pictures and are responsible for central and shading vision. The periphery zone of the retina, which envelops the macula, contains photoreceptor cells called bars, which respond to bring down light levels yet are not shading sensitive. The bars are responsible for periphery vision and night vision. The optic nerve passes on signals made by the photoreceptors (cones and bars). Each photoreceptor is joined to the optic nerve by an unobtrusive nerve branch. The optic nerve is related with nerve cells that pass on signs to the vision point of convergence of the cerebrum, where they are deciphered as visual pictures.
