The Eye – Its Anatomy and Physiology II -- Lesson 262
The ciliary body secretes a fluid called aqueous humor other than the shape of the lens. This fluid flows through the anterior chamber and posterior chamber of the eye. The fluid remains constant and that is produced and leaves the eye through a canal which carries it into the bloodstream. Vitreous chamber is the other cavity of the eye, which is a major region behind the lens which is filled with soft, jelly-like material. This vitreous humor regulates the shape of the eyeball and is not perfectly formed again. Blindness can be caused due to escape from the eye. To further refract light rays, both these humors (aqueous and vitreous) function. The thin, delicate and sensitive nerve layer of the eye is retina. This retina is a layered structure with many layers of neurons interconnected by the synapses. Light energy, which is in the form of waves travels through the eye, it is refracted by the cornea, lens and fluids. Cone-rod dystrophy explains a number of diseases where the loss
