Ophthomology
Basic Ophtho Terms
| Term | Definition |
|---|---|
| Amblyopia | Lazy Eye |
| Anterior Chamber | fluid-filled space in the front of the eye between the cornea and the iris. |
| Aqueous Humor | The clear fluid that fills the anterior chamber while nourishing the eye and maintaining its pressure by flowing to drain through the trabecular meshwork |
| Astigmatism | Irregularly shaped cornea that causes light to refract ineffectively |
| Cataract | Cloudy or opaque portions of the natural lens |
| Choroid | The thin layer of major blood vessels that lie between the retina and sclera |
| Ciliary Body | The two types of muscles that holds the lens in place. It also helps control intraocular pressure |
| Ciliary Muscle | The smooth muscle portion of the ciliary body that is responsible for controlling the lens shape to allow for focusing on both near and distance objects |
| Ciliary Process | The portion of the ciliary body that produces the aqueous humor |
| Cones | Receptor cells in the retina that detect color |
| Conjunctiva | Mucous membrane that lines the inner surface of the eyelids and covers the sclera, except the cornea |
| Conjunctivitis | Pink Eye |
| Cornea | Dome shaped window of the eye that provides most of the eyes optical power |
| Corneal Transplant | Surgery to remove the diseased or scarred cornea and replace it with a healthy cornea from a donor |
| Diopter | Measures the degree at which light converges or diverges within the eye or through spectacles |
| Drusen | White or yellowish deposits within the retina that commonly occur after age 60 |
| Emmetropia | When someone has no astigmatism |
| Glaucoma | When intraocular pressures are too high, this results in a group of diseases that can damage the optic nerve |
| Hyperopia | Farsightedness |
| Intracorneal Ring | The insertion of a ring into the periphery of the cornea to change its shape to correct nearsightedness |
| Intraocular Lens | A plastic implant used to replace the natural lens of the eye (IOL) |
| Keratoconus | When the cornea begins to protrude into a cone shape due to the thinning of the cornea |
| LASIK | A refractive surgery that peels back the top layer of the cornea allowing the middle layer to be sculpted by a laser to eliminate refractive errors |
| Lens | An elastic almond-shaped structure in the eye that focuses images into the retina |
| Lensectomy | The surgical removal of the lens. This is used to remove cataracts |
| Macula | The central portion of the retina that is responsible for providing the sharpest sight |
| Macular Degeneration | "Rusting of the retina" |
| Melanoma | A malignant tumor from pigmented tissues |
| Myopia | Nearsighted |
| Optic Nerve | Connects the retina to the primary visual cortex of the brain |
| Pars Plana | The flattened back portion of the ciliary body |
| Posterior Chamber | The space between the back of the iris and the front surface of the vitreous that is filled with vitreous humor |
| Presbyopia | When the natural lens loses its elasticity due to aging which is the reason older people need readers |
| Ptosis | Drooping of the upper eyelid |
| Retina | The innermost layer of blood vessels and nerves that serve as the film of the eye |
| Retinal Pigmentosa | Abnormal pigmentation on the retina that can hinder vision |
| Retinal Cell Transplantation | The transplantation of healthy retina cells onto areas of damaged retina |
| Retinoblastoma | Retinal tumor |
| Retinopathy of Prematurity | Diseased retina in premature infants |
| Rods | Receptor cells in the retina that are sensitive to varying degrees of light and helps individuals see in dim light |
| Sclera | The white of the eye |
| Srabismus | An imbalance in the ocular muscles that hold the eyeball which causes the eye to be misaligned |
| Trabecular Meshwork | Tubes and canals behind the iris that filters the aqueous humor allowing it to drain into the bloodstream |
| Uvea | Made up by the iris, ciliary body, choroid, and the majority of the eyes blood vessels |
| Uveitis | The inflammation of any of the structures of the uvea |
| Vitrectomy | The surgical removal of the vitreous, blood, and membranes from the eye |
| Vitreous Humor | The clear jelly that fills the eye behind the lens |
| Endothelial Transplant | The transplantation of healthy endothelial cells onto the cornea that is missing patches of cells |
| Electrolysis for Eyelashes | Procedure that permanently removes ingrown or misdirected lashed by destroying the hair root with a fine needle and electric current |
| Electrolysis | A chemical process using direct electric currents to split compounds |
| Retinopathy | Umbrella term for any type of damage/disease to the retina |
| Posterior | Back of a structure |
| Anterior | Front of a structure |
| Laser Retinopexy | In office procedure with a focused laser to create tiny burns or "welds" around a retinal tear or hole |
