Abstract
As an organ responsible for vision, the eye has anatomical structures that enable it to process light signals into electrical signals that the brain can interpret as vision. The retina is endowed with neurons that facilitate the conversion of the light signal (the photoreceptors) to electrical energy. The susceptibility of retinal neurons to various insults leads to a degenerative process that accounts for diseases such as retinitis pigmentosa, age-related macular degeneration, and glaucoma. The pathophysiology of the three ocular neurodegenerative disorders and the current pharmacological approaches to their treatment will be discussed in this chapter.
