Your Comprehensive Eye Exam in Glendale, CO

A comprehensive eye exam includes a number of tests and procedures to examine and evaluate the health of your eyes and the quality of your vision. These tests range from simple ones, like having you read an eye chart, to complex tests, such as using a high-powered lens to examine the health of the tissues inside of your eyes.

Here are some tests you are likely to encounter during a routine comprehensive eye exam:

Retinoscopy

This test helps your doctor get a good approximation of your eyeglasses prescription. For retinoscopy, the room lights are dimmed and an instrument containing wheels of lenses (called a phoropter) is positioned in front of your eyes. You will be asked to look at an object across the room (usually the big “E” on the wall chart or screen) while your doctor shines a light from a hand-held instrument into your eyes from arm’s length and flips different lenses in front of your eyes.

Based on the way the light reflects from your eye during this procedure, your doctor can get a very good idea of what your eyeglasses prescription should be. This test is especially useful for children and non-verbal patients who are unable to accurately answer the doctor’s questions.

Refraction

This is the test your doctor uses to determine your exact eyeglasses prescription. During a refraction, the doctor puts the phoropter in front of your eyes and shows you a series of lens choices. He or she will then ask you which of the two lenses in each choice (“1 or 2,” “A or B,” for example) make the letters on the wall chart look clearer.

Based on your answers, your doctor will determine the amount of nearsightedness, farsightedness and/or astigmatism you have, and the eyeglass lenses required to correct these vision problems (which are called refractive errors).

Autorefractors

An autorefractor evaluates the way an image is focused on the retina, where vision processing takes place, without the need for you to say anything. This makes autorefractors especially useful when examining young children or people who may have difficulty with a regular (“subjective”) refraction. We use automated refractions and subjective refractions together during a comprehensive exam to determine your eyeglasses prescription.

Cover test

While there are many ways for your eye doctor to check how your eyes work together, the cover test is the simplest and most common.

During a cover test, the eye 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 target. As they do this, eye doctors observe how much each eye has to move when uncovered to pick up the fixation target. The test is then repeated as you focus on a near object.

Cover tests can detect even very subtle misalignments that can interfere with your eyes working together properly (binocular vision) and cause amblyopia or “lazy eye.”

Slit-lamp examination

The slit lamp is an instrument that the eye doctor uses to examine the health of your eyes. Also called a biomicroscope, the slit lamp gives your doctor a highly magnified view of the structures of the eye, including the lens behind the pupil, in order to thoroughly evaluate them for signs of infection or disease.

The slit lamp is basically an illuminated binocular microscope that’s mounted on a table and includes a chin rest and head band to position the patient’s head properly. With the help of hand-held lenses, your doctor can also use the slit lamp to examine the retina (the light-sensitive inner lining of the back of the eye.)

Pupil dilation

Your comprehensive exam may include the use of dilating drops. These medicated eye drops enlarge your pupil so your doctor can get a better view of the internal structures in the back of the eye. Dilating drops usually take about 20 minutes to start working. When your pupils are dilated, you will be sensitive to light, because more light is getting into your eye. You may also notice difficulty reading or focusing on close objects. These effects can last for up to several hours, depending on the strength of the drops used.

If you don’t have sunglasses to wear after the exam, disposable sunglasses will be provided to help you drive home. Dilation is very important for people with risk factors for eye disease, because it allows for a more thorough evaluation of the health of the inside of your eyes.

Often times the Optomap may be used in lieu of dilation.

Optomap Retinal Imaging Is Available At Our Denver Eye Care Clinic

The Optomap Retinal Exam captures a digital image of the retina, revealing important information for the comprehensive evaluation of your eyes. The Optomap Retinal Exam aids in the detection and diagnosis of serious eye conditions such as diabetic retinopathy, retinal detachments, macular degeneration, and other pathologies such as melanomas. In most cases, Optomap photography can replace your need for dilation.

The Optomap Exam is an additional fee of $35. While not covered by insurance, it is preferred by most patients in order to avoid the inconvenience of dilation.
