Question 1

Color Vision Tests

Answer 1

Use of polychromic (multicolored) charts to determine the ability of the patient to recognize color

Question 2

Fluorescein Angiography

Answer 2

Process of injecting a dye (fluorescein to observe the movement of blood and detect lesions in the macular area of the retina. Used to determine the detachment of the retina.

Question 3

Fluorescein Staining

Answer 3

Applying dye eye drops that are a bright green fluorescent color. Used to look for corneal abrasions of ulcers.

Question 4

Keratometer

Answer 4

An instrument used to measure the curvature of the cornea

Question 5

Keratometry

Answer 5

Measurement of the curvature of the cornea using an instrument called the keratometer

Question 6

Ophthalmoscope

Answer 6

Instrument used to examine the inside of the eye through the pupil

Question 7

Ophthalmoscopy

Answer 7

Examination of the interior of the eyes using an instrument called an ophthalmoscope. The physician dilates the pupil in order to see the cornea, lens, and retina. Used to identify the abnormalities in the blood vessels of the eye and some systemic diseases.

Question 8

Optometer

Answer 8

Instrument used to measure how well the eye is able to focus images clearly on the retina

Question 9

Refractive Error test

Answer 9

Vision test for a defect in the ability of the eye to accurately focus on the image that is hitting it. Refractive errors result in myopia and hyperopia.

Question 10

Slit Lamp Microscopy

Answer 10

Examining the conjunctiva, cornea, iris, and lens of the eye,

Question 11

Snellen Chart

Answer 11

Chart used for testing distance vision named for Dutch ophthalmologist Hermann Snellen. It contains letters of varying size and is administered from a distance of 20 feet. A person who can read at 20 feet what the average person can read at this distance is said to have 20/20 vision.

Question 12

Tonometry

Answer 12

Measurement of the intraocular pressure of the eye using a tonometer to check for the condition of glaucoma. Part of a normal eye exam for adults

Question 13

Visual Acuity (VA) test

Answer 13

Measurement of the sharpness of a patient’s vision. Usually, a Snellen chart is used for this test in which the patient identifies letters from a distance of 20 feet.

Question 25

Phacoemulsification:

Answer 25

Use of high-frequency sound waves to emulsify (liquefy) a lens with a cataract (ECCE) which is then aspirated (removed by suction) with a needle

Question 26

Photorefractive keratectomy

Answer 26
