Comprehensive Eye Exam

A comprehensive eye exam is recommended anually to monitor your eye health and visual function. This exam can take 45 minutes to an hour in length. A comprehensive eye exam evaluates how well you see and also identify potential eye diseases. Eye diseases, such as glaucoma and macular degeneration, can result in serious vision loss as often patients with these diseases donĀ“t experience any visual symptoms before vision loss occurs.
In routine comprehensive eye exam doctor generally perform following tests depending on patient’s need:
  • Retinoscopy
    This test is performed early in the eye exam in order to obtain an approximation
    of your prescription from which to start.
  • Refraction Test
    Visual acuity or refraction test to determine the degree of nearsighted, farsighted or astigmatism in a person.
  • Autorefractors
    An autorefractor evaluates the way an image is focused on your retina, where vision processing takes place.
  • Cover test
    During a cover test doctor will have you focus on a small object at distance and will then cover each of your eyes alternately while you stare at the object. Doctors observe how much each eye has to move when uncovered to pick up the fixation target. This helps them to detect strabismus, or eye turn, which can cause amblyopia, poor depth perception and other binocular vision problems.
  • Slit-lamp examination
    The slit lamp also known as biomicroscope, allows the doctor to see a highly magnified image of the eye structures for signs of infection or disease.
  • Glaucoma test (tonometer)
    The most common glaucoma test is the “puff-of-air” test, technically known as the non-contact tonometer.
  • Visual field testing
    This test is used to find the possible presence of blind spots in the eyes because of any desiese.
  • Dilation
    Dilating drops are used to make the pupils bigger in order to get a better view of the internal structures of the eye.
