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






2. Right eye (OD)






3. Layers in the cornea






4. 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.






5. A topical anesthetic.






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






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






8. Every _ Hour






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






10. Upward and diagonally






11. Proparacaine - Tetracaine - Cocaine






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






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






14. A test that measures the pressure inside your eye - which is called intraocular pressure.






15. Glaucoma causes...






16. The creation of a photograph of the interior surface of the eye.






17. What lens material is the easiest to break?






18. By mouth






19. 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.






20. What are plus lenses used to correct?






21. Provide a bigger field of vision.






22. Associated with aging and results in damaging sharp and central vision.






23. 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.






24. What are used to treat dry eyes?






25. This is the pathway between the ye and the brain along which the signals produced by the retina travel to the brain.






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






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






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






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






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






31. The procedure using ultraviolet radiation from a laser to remove tissue.






32. The lifeline into and out of the practice.






33. The light sensitive part of the eye.






34. What is the name for the part of the frame that connects the two eyewires?






35. 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.






36. The ability to maintain visual focus on an object with both eyes creating a single visual image.






37. The distance from the back surface of the lens to the front of the eye.






38. A broken blood vessel between the sclera and conjunctiva.






39. 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.






40. The interior portion of the eyeball that may be seen on ophthalmoscopy.






41. Ultraviolet Coating protect the eye from damaging...






42. Downward and diagonally






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






44. What is the frame height - the most vertical dimension of the lens opening also known as?


45. A paralysis of the ciliary muscle - so accommodation can't occur.






46. Provides nutrients for the lens and posterior cornea.






47. As needed






48. Drop






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






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