Medical Assistant = Does not commonly work in ophthalmology or optometric settings, requires additional training. Signup and view all the answers

Match the following terms with their definitions:

Refractive errors = A common eye disorder, refers to the way light from objects is focused through the eye to form an image on the retina. Cornea = The part of the eye where light waves enter. Retina = The back of the eye where the focal point of light should touch. Signup and view all the answers

Match the following procedures with their associated eye disorders:

Glasses or contact lens = Corrects most common disorders. Medications and surgery = Required for more serious problems, can only be performed by an ophthalmologist. Separate training thru ophthalmic medical technician program = Required for Medical Assistants to work in ophthalmology or optometric settings. Signup and view all the answers

Match the following eye conditions with their descriptions:

Myopia = Condition in which images of distant objects come into focus in front of the retina. Nearby objects are seen clearly but objects far away are blurred. Hyperopia = Condition where images come into focus behind the retina. Faraway objects are seen clearly but nearby objects are blurry. Presbyopia = Form of farsightedness that occurs with age, secondary to a loss of accommodation of the lens. Objects close to the eyes are blurry. Astigmatism = Condition where light refracts onto the retina off-center due to an unevenly curved cornea or abnormal lens shape. Results in blurry or double vision. Signup and view all the answers

Match the following terms with their descriptions:

Vitreous humor = The eyeball's inner fluid. Its amount can change the focal point of the eye. Retina = The point in the eye where light ideally focuses to create clear vision. Fovea = The ideal place on the retina for the light to focus on, where visual acuity is the highest. LASIK = Laser vision correction surgery used to correct the curvature of the cornea in conditions like astigmatism. Signup and view all the answers

Match the following eye conditions with their causes:

Myopia = Eyeball is too long due to too much inner fluid. Hyperopia = Eyeball is too short. Presbyopia = Loss of accommodation of the lens due to aging. Inner-eye muscles atrophy causing the lens to become less elastic. Astigmatism = Unevenly curved cornea or an abnormal lens shape, often due to genetics. Signup and view all the answers

Match the following eye conditions with their effects on vision:

Myopia = Ability to only see objects near to you clearly. Objects far away are blurred. Hyperopia = Ability to only see objects far away clearly. Objects close to the eyes are blurry. Presbyopia = Difficulty in seeing objects up close as we age. Astigmatism = Blurry, double-vision due to off-center focus on the retina. Signup and view all the answers

Match the following terms to their meanings in the context of vision testing:

20/20 Vision = A person can see an object clearly from 20 feet away, just like folks with 'normal vision' can. 20/25 Vision = A person standing at 25 feet away from the same chart could see that same line clearly, but our patient needs to be 5 feet closer to read the same line. 20/10 Vision = A person can read smaller letters further down the chart. They are 20 feet away reading letters that a person with normal vision would need to be 10 feet closer to see. 20/4 Vision = A person can see an object clearly at 20 feet away where most humans would need to be just 4 feet away to see it clearly.

Match the following terms to their meanings in the context of patient-centered care & communication:

Corrective lenses for distance vision = Lenses that the patient should wear during DVA testing to help accurately determine if the prescribed lenses should be changed. Lenses corrected for near vision = Lenses that a patient should not wear during DVA testing, as this can alter test results. Both eyes open during individual eye tests = A directive given to the patient to prevent inaccurately poor results due to refocusing after closing or squinting. Re-reading incorrect answers = An opportunity given to the patient to correct any mistakes before marking results. Signup and view all the answers
