Certified Paraoptometric Study Guide 2023/2024 Ophthalmoscopy The Examination of the inside of the eye. Vertex distance The distance from the back surface of the lens to the front of the eye. Fundus The interior portion of the eyeball that may be seen on ophthalmoscopy. Turn the eye downward What is the primary function of the inferior rectus muscle? Sub conjunctival hemorrhage A broken blood vessel between the sclera and conjunctiva. What does a lensometer measure? Back vertex power which includes sphere and cylinder power. Aspheric lenses provide a smaller field of vision. False Visual acuity The measure of the finest detail the eye may detect. Corneal Edema When water is retained and swelling occurs in the cornea. Snellen Chart The chart most often used to measure acuity at distance. 0.25 D The smallest unit of lens measure. Which type of lens will have the same power in all areas of the lens? Spherical What lens material is the easiest to break? Glass Trivex A mid-index lens material that is thinner than glass or CR-39, free from distortion and aberration and able to be used as a safety lens. Sphygmomanometer and stethoscope Two instruments are used to test patient blood pressure. Conventional daily wear lenses One type of contact lens is applied after waking and removed before going to sleep. Macula The part of the retina responsible for sharp, clear vision. Optic Disc The portion of the optic nerve that is formed by the meeting of all retinal nerve fibers. Photoablation The procedure using ultraviolet radiation from a laser to remove tissue. What is the name for the part of the frame that connects the two eyewires? Bridge Monovision Corrects one eye for distance and the other eye for near and can be used to correct presbyopia. Phoropter The instrument that contains lenses and can be used to determine a spectacle correction. What does a tonometer measure? Pressure in the eye. Proparacaine A topical anesthetic. What are used to treat dry eyes? Artificial Tears and Lubricants Five Layers in the cornea Aqueous humor Provides nutrients for the lens and posterior cornea. Retina The light sensitive part of the eye. Rods are the photoreceptors that provide color vision. False Glaucoma causes damage to the eye. True Diabetic patients may have vision loss due to diabetic retinopathy. True What is the purpose of HIPPA. Improve the portability and continuity of health insurance overage, improve access to long-term care services and coverage, to simplify administrative care. Cataract Surgery Surgical removal of the lens, usually replaced with a plastic intraocular lens. Glaucoma Surgery Numerous different surgeries that facilitate the escape of excess aqueous humor from the eye to lower the intraocular pressure and a few that lower IOP by decreasing the production of aqueous humor. Mydriatics Dilators Miotics Constrictors Eye Anaesthetics Proparacaine, Tetracaine, Cocaine Eye Dilators Tropicamide, Atropine, Scopolamine, Phenylephrine Cycloplegia A paralysis of the ciliary muscle, so accommodation can't occur. Keratometry Measurement of the form and curvature of the cornea. Retinoscopy A method of determining the state of refraction of the eye by illumination the retina with a mirror and observing the direction of movement of the retinal illumination and adjacent shadow when the mirror is turned. Subjective Refraction The result of the refraction depends on the patient's ability to discern changes in clarity. This process relies on the cooperation of the Patient. Ophthalmoscopy A test that allows a doctor to see inside the back of the eye and other structures using a magnifying instrument and a light source. Binocular Vision The ability to maintain visual focus on an object with both eyes creating a single visual image. Tonometry A test that measures the pressure inside your eye, which is called intraocular pressure. Visual Fields The entire area that can be seen when the eye is directed forward including that which is seen with peripheral vision. Biomicroscopy The Optothalmic examination of the eye by use of a slit lamp and a magnifying lens. Fundus Photography The creation of a photograph of the interior surface of the eye. Tomography Refers to imaging by section or sectioning, through the use of any kind of penetrating wave. Topography Computer-assisted method of mapping the surface curvature of the cornea. gtt Drop qhs At bedtime q_h Every _ Hour p.o. by mouth p.r.n. As needed Ciliary Muscle Controls the focusing power of the eye by changing the shape of the lens. Superior Rectus upward and inward Inferior rectus downward and inward Internal/medial rectus inward external/lateral rectus outward superior oblique downward and diagonally inferior oblique upward and diagonally
