Eye Exam Retinoscopy Test: What is It?

At your D’Ambrosio Eye Care eye exam you will probably have a test called Retinoscopy. Retinoscopy is a technique to measure the refractive error of the eye. Your eye doctor will use a retinoscope to shine a light into the back of the eye and observe the reflection of light off the retina.  While moving the light, lenses of different powers are placed in front of the eye until the refection of light in neutralized.  The combination of lenses required to neutralize the reflection of light is used to calculate an estimate of the patient's prescription for eyeglasses. 

Retinoscopy has a number of uses.  Your doctor can use retinoscopy as a starting point when determining the final prescription for glasses.  In some patients, such as young children or people with severe mental disabilities, retinoscopy may be the only reliable method of determining a spectacle prescription.  Observing the appearance of the reflection of light when performing retinoscopy can help an eye doctor confirm certain ocular conditions such as cataracts or keratoconus.  It can also be used to help determine the accommodative, or focusing, ability of the patient.
