The Eye
| Question | Answer |
|---|---|
| Chamber of the eye that contains a water fluid called aqueous humor | Anterior |
| Transparent, outer covering of the anterior portion of the eye | Cornea |
| Chamber of the eye that contains a gelatinous fluid called vitreous humor | Posterior |
| Pigmented vascular layer between the sclera and the retina. | Choroid |
| Mucous membrane that lines the eyelids and outer eye surface. | Conjunctiva |
| Nerve tissue in the inner posterior part of the eye | Retina |
| Transparent structure posterior to the pupil that bends light rays on the retina to aid in focusing. | Lens |
| Opening in the eye that allows light to enter | Pupil |
| Visual receptors in the retina that respond to light waves for color vision | Cones |
| Visual receptors in the retina that respond to light waves for dim vision | Rods |
| Nerve that carries transmissions to the brain | Optic |
| Watery liquid secreted by the ciliary processes that fills the anterior or posterior chambers of the | Aqueous humor |
| Duct in the anterior chamber that carries filtered aqueous humor to the veins and bloodstream | Canal of Schlemm |
| Tubes that carry tears to the lacrimal sac | Lacrimal ducts |
| Central region of the retina; responsible of central vision | Macula lutea |
| Jelly-like mass filling the inner chamber between the lens and retina that gives bulk to the eye | Vitreous |
| Mesh like structure in the anterior chamber that filters the aqueous humor as it flows into the scleral venous sinus | Trabecular meshwork |
| Double vision | Diplopia |
| Eyestrain | Asthenopia |
| Blind spot in vision | Scotoma |
| Involuntary, rapid, oscillating movement of the eyeball | Nystagmus |
| Abnormal protrusion of one or both eyeballs | Exophthalmos |
| Distorted vision caused by an oblong or cylindrical curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina | Astigmatism |
| Farsightedness; difficulty seeing close objects when light rays are focused on a point behind the retina | Hyperopia |
| Nearsightedness; difficulty seeing distant objects when light rays are focused on a point in front of the retina | Myopia |
| Inflammation of the eyelid | Blepharitis |
| Opaque clouding of the lens causing decreased vision | Cataract |
| Chronic nodular inflammation of a tarsal gland, usually the result of a blocked duct | Chalazion |
| An acute infection of a sebaceous gland of the eyelid; also called a sty | Hordeolum |
| Abnormal overflow of tears caused by blockage of the lacrimal duct | Epiphora |
| Right or left eye deviates inward towards the nose | Esotropia |
| Right or left eye deviates outward, away from the nose | Exotropia |
