Eye Examination

Do it for each other

Examination of the Eye: A complete eye examination:

Eye Examination, Eye Tests, Dilated Retinal Fundus examination are all part of a complete eye exam which involves a series of tests designed to evaluate your vision and check for eye diseases. Examination of eye, reading the Eye chart, and a Dilated Retinal Fundus examination are just a small part of a complete eye examination.

Periodic eye and vision examinations are an important part of preventive health care. Many eye and vision problems have no obvious signs or symptoms. As a result, individuals are often unaware that problems exist. Early diagnosis and treatment of eye and vision problems are important for maintaining good vision and eye health, and when possible, preventing vision loss.

A comprehensive adult eye and vision examination may include, but is not limited to, the following tests. Individual patient signs and symptoms, along with the professional judgment of the doctor, may significantly influence the testing done.

Patient History :

A patient history helps to determine any symptoms the individual is experiencing, when they began, the presence of any general health problems, medications taken and occupational or environmental conditions that may be affecting vision. Dr. Duplessie will ask about any eye or vision problems you may be having and about your overall health. He will also ask about any previous eye or health conditions of you and your family members.

Visual Acuity

Reading charts are often used to measure visual acuity.

Visual acuity measurements evaluate how clearly each eye is seeing. As part of the testing, you are asked to read letters on distance and near reading charts.

When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet in order to see it clearly. Normal distance visual acuity is 6/6 or 20/20.

Keratometry

This test measures the curvature of the cornea. This measurement is particularly critical in determining the proper fit for contact lenses and to determine if a patient can have lasik.

Refraction

Refraction is determining if there is a need for glasses [a refractive error] with a phoropter

Autorefractor

Refraction is conducted to determine the correct glasses or contact lens prescription to for a refractive error (nearsightedness, farsightedness, or astigmatism). The patient’s responses fine tune the result to get the the clearest vision.

 

Eye Focusing, Eye Teaming, and Eye Movement Testing

Assessment of accommodation, ocular motility and binocular vision determines how well the eyes focus, move and work together. In order to obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work together.

 

Tonometry

measures eye pressure. Elevated pressure in the eye signals an increased risk for glaucoma.

Slit Lamp Examination:

External examination using a microscope called a slit lamp permits evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue.

Fundus Examination – Examination of the Retina and Optic Nerve:

Evaluation of the lens, retina and posterior section of the eye should be done through a dilated pupil to provide a better view.

Additional testing may be needed based on the results of the previous tests to confirm or rule out possible problems, to clarify uncertain findings, or to provide a more in-depth assessment.
