Retina, Cornea and Eye Disorders

The retina is a thin layer of tissue on the inside back wall of eye. It contains millions of light-sensitive cells and other nerve cells that receive and organize visual information. Retina sends this information to brain through optic nerve, enabling one to see. The main area of retina contains a high density of color-sensitive photoreceptor cells called cones which are responsible for color vision and hence any defect and alteration in the main area of the retina will lead to Color vision defects.

Eye consists of terribly sensitive and fragile tissues and each part of this serves its own function to keep up its general vision. The cornea is the front part of the eye which is transparent and covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, accounting for roughly two-third portions of the eye's total optical power.

There are many disorders associated with eye, principally with retina and cornea. These includes Acanthamoeba Keratitis, Amblyopia, Astigmatism, Bell's Palsy, Bionic Eye Impulse, Blepharitis, Blurry Vision, Chalazion, CMV Retinitis, Conjunctivitis (Pink Eye), Corneal Abrasion (Scratched Eye), Corneal Collagen Crosslinking, Corneal Ulcer, Detached Retina, Diabetic Retinopathy, Double Vision (Diplopia), Dry Eye Infographic, Eye Herpes, Eye Occlusions (Eye Strokes), Fuchs' Corneal Dystrophy, Glaucoma, Hyperopia (Farsightedness), Hyphema, Keratoconus, Macular Dystrophy, Macular Hole, Meibomian Gland Dysfunction, Milia (Eyelid Cysts), Myopia (Nearsightedness), Nystagmus, Ocular Hypertension, Ocular Migraine, Ocular Rosacea, Optic Neuritis and Optic Neuropathy, Photophobia (Light Sensitivity), Pterygium, Ptosis (Drooping Eyelid) etc.
