The movement of the eye outward toward the temple. - Answer-abduction The measurement of optical aberrations of the visual system using a device called a wavefront analyzer or an aberrometer. - Answer-aberrometry A scratch. - Answer-abrasion A localized collection of pus surrounded by inflamed tissue. - Answer-abscess A severe visual field defect in which the largest and brightest stimulus cannot be seen; blindness at that specific location. - Answer-absolute scotoma The change in the curvature of the crystalline lens that helps to focus images of objects close to the eye. - Answer-accommodation A chemical injury to tissue, caused by an agent of low pH. - Answer-acidic burns An infection with human immunodeficiency virus (HIV) that causes a compromised immune system. - Answer-acquired immunodeficiency syndrome (AIDS) Refers to a condition that flares up suddenly and persists for only a short time. - Answer-acute The lower portion of the multifocal lens (usually the lower part) that provides correction for near vision. Also called segment or near add. - Answer-add The movement of the eye inward toward the nose. - Answer-adduction A family of viruses involved primarily in respiratory infections; can cause highly contagious forms of conjunctivitis. - Answer-adenovirusThe tissues and structures surrounding the eye; includes the orbit, extraocular muscles, eyelids, and lacrimal apparatus. - Answer-adnexa A pupil with normal iris function that fails to constrict normally with direct light stimulation but reacts strongly consensually, or when the fellow eye is stimulated. Usually secondary to optic nerve disease. - Answer-afferent pupillary defect (APD) The retinoscopic reflex movement that is in the opposite direction from the movement of the streak of light from the retinoscope; typical of the myopic eye. - Answer-"against motion" A disease in which sensory cells of the macula degenerate, resulting in a loss of central vision; usually affects older people. - Answer-age-related macular degeneration A chemical injury to tissue, caused by an agent of high pH. - Answer-alkali burn A condition in which the body produces antibodies to foreign materials such as food, plant pollens, or medications. - Answer-allergic reaction A test performed by placing an occluder over one eye and then moving it slowly over to the other eye to detect a tendency for the eyes to deviate while under the occluder (such an ocular misalignment is known as a phoria). Also called cross-cover test. - Answer-alternate cover test The joining and enlargement of a nasal step visual field defect and an arcuate scooter to cause loss of the entire upper or lower visual field. - Answer-altitudinal scotoma Decreased vision present without apparent abnormalities in the ocular anatomy and uncorrectable by spectacles or contact lenses; results from visual deprivation in early childhood. - Answeramblyopia The refractive state of an eye that is unable to focus correctly due to a refractive error. - Answerametropia A test for determining the presence and location of defects in the central portion of the visual field. - Answer-Amsler grid test The structure of an organism. - Answer-anatomyA drug that causes a temporary deadening of a nerve, resulting in loss of feeling in the surrounding tissue. - Answer-anesthetic The formation of new blood vessels - Answer-angiogenesis A method of examining and recording size, structure, and location of blood vessels in organ systems, using fluorescent dyes. - Answer-angiography A condition in which the pupils are of unequal size. - Answer-anisocoria The front part of a structure. - Answer-anterior The junction of the cornea and the iris, from which aqueous humor leaves the eye. Also called filtration angle. - Answer-anterior chamber angle The small compartment between the cornea and the iris that is filled with a clear, transparent fluid called aqueous humor. - Answer-anterior chamber Insufficient blood flow to the optic nerve head resulting in a lack of oxygen and subsequent infarction of (loss of) the nerve fibers and loss of vision. - Answer-anterior ischemic optic neuropathy (AION) The front of the eye; includes the structures between the front surface of the cornea and the vitreous. - Answer-anterior segment A process or agent that prevents new blood vessel growth. - Answer-anti-angiogenesis A drug that combats a bacterial infection. - Answer-antibiotic A chemical substance that the body manufactures to neutralize an infecting microorganism, toxin, or foreign agent. - Answer-antibody
