Certified Paraoptometric Exam

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Layers in the cornea






2. Upward and diagonally






3. Computer-assisted method of mapping the surface curvature of the cornea.






4. Tropicamide - Atropine - Scopolamine - Phenylephrine






5. Inward






6. When the vision in one of the eyes is reduced because the eye and the brain aren't working together properly. The eye itself may look normal - but it's not being used normally because the brain is favoring the other eye.






7. What are cycloplegic drugs used for?






8. What's it called when the cornea thins and bulges forward?






9. Transparent covering of the eye that lies between the eyelid and front of the eye.






10. A group of diseases that can damage the eye's optic nerve and result in the vision loss and blindness. It occurs when the normal fluid pressure inside the eyes slowly rises.






11. Surgical removal of the lens - usually replaced with a plastic intraocular lens.






12. Involves an imbalance in the positionig of the two eyes. I can cause the eys to cross in or tuyrn out. It's cause by a lack of coordination between the eyes.






13. Refers to imaging by section or sectioning - through the use of any kind of penetrating wave.






14. By mouth






15. A lens with no power.






16. Laser-based - non contact - noon invasive imaging technique.






17. 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.






18. The part of the retina responsible for sharp - clear vision.






19. The entire area that can be seen when the eye is directed forward including that which is seen with peripheral vision.






20. The measure of the finest detail the eye may detect.






21. 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.






22. Two instruments are used to test patient blood pressure.






23. When water is retained and swelling occurs in the cornea.






24. Increases visual acuity because it reduces internal lens reflections.






25. Provide a bigger field of vision.






26. The portion of the optic nerve that is formed by the meeting of all retinal nerve fibers.






27. What are plus lenses used to correct?






28. What lens material is the easiest to break?






29. Upward and inward






30. Located behind the pupil - and is the secondary mechanism of focus - adjusting the amount of focus the light image requires before it reaches the retina.






31. The nerve center of the eye where light is converted into an electrical signal that travels along the optic nerve to the brain.






32. Controls the focusing power of the eye by changing the shape of the lens.






33. Is a clouding of the eye's lens and is the leading cause of blindness.






34. A topical anesthetic.






35. What are used to treat dry eyes?






36. If a patient claims to have pain in the ye but does not have any other symptoms - when do you schedule them for an appointment?






37. Back vertex power which includes sphere and cylinder power.






38. Protected health Information






39. Constrictors






40. A layer located behind the retina and absorbs unused radiation.






41. Proparacaine - Tetracaine - Cocaine






42. 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.






43. The instrument that contains lenses and can be used to determine a spectacle correction.






44. Which type of lens will have the same power in all areas of the lens?






45. Measurement of the form and curvature of the cornea.






46. Downward and diagonally






47. Swelling or infection of the membrane lining the eyelids or Conjunctiva.






48. What provides the major refractive power of the eye?






49. A jelly-like subastance located in the anterior chamber.






50. An ophthalmic stain - available in liquid form and is the most commonly used ophthlmic dye.
