• The eyes are our main sense organs. Light enters the eye through the pupil and transparent cornea, it passes through the lens and is focused on to the light-sensitive retina.
• In the retina light stimulates receptors (rods and cones) to generate nerve impulses in sensory neurons; these impulses travel via neurons in the optic nerve to areas of the brain concerned with vision. In the visual cortex of the brain the impulses are interpreted as an image.
• Hypermetropia Describes long-sightedness in which light rays are focused beyond the retina (hyper- beyond/above). The light rays when measured focus beyond the retina (metr- measure).
• Myopia Short-sightedness. My comes from myein, meaning to close.Presumably the eye tends to close when trying to view a distant object.
• Emmetropia Light falls directly on to the retina in its correct position, with no errors. This word refers to normal/ideal vision
• The word cornea comes from the Latin word corneus, also meaning horny
• Corneoplasty is synonymous with keratoplasty, anoperation performed to replace a diseased or damaged cornea with a corneal graft.
• Abnormal curvatures of the cornea cause light rays to focus on the retina unevenly. This is known as astigmatism
• The sclera and cornea are covered at the front of the eye with a delicate, transparent membrane that also lines the inner surface of the eyelids.This membrane is the conjunctiva; it is prone to irritation and infection, giving rise toconjunctivitis.
• Papillae• Vascular reaction consisting of fibro vascular mounds with central vascular tuft. Can be large-cobblestone or giant papillae-allergic conjunctivitis
• Follicles Small translucent, avascular mounds of plasma cells and lymphocytes seen in keratoconjunctivitis, herpes simplex virus, Chlamydia, drug reactions
