Eye Exams: Medical History

Pre-testing is a detailed process that gathers all necessary information for the optometrist in advance of the optometrist-administered eye examination. This process involves completing a detailed patient history, as well as a series of standard tests. Pre-testing is an essential part of the comprehensive eye exam process, providing valuable information and visuals for both the optometrist and the patient.

Information gained by asking specific questions, either of the patient or their caregivers, to obtain information useful in formulating a diagnosis and providing medical care to the patient. The medically relevant complaints reported by the patient are referred to as symptoms, in contrast with clinical signs, which are ascertained by direct examination. The medical history, together with the physical examination, enables the optometrist to form a diagnosis and treatment plan.

An autorefractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. It achieves this by measuring how light is changed as it enters a person's eye. Auto-refraction is used to provide the starting point for the optometrist in subjective refraction tests.

Keratometry is the measurement of the corneal curvature; corneal curvature determines the power of the cornea. Differences in optical power across the cornea results in astigmatism, so keratometry measures astigmatism. A keratometer is the diagnostic instrument used to perform keratometry and to assess the extent and axis of astigmatism.

Corneal pachymetry is the process of measuring the thickness of the cornea. A pachymeter is a medical device used to measure the thickness of the eye's cornea. Uses of the device include performing corneal pachymetry in advance of refractive surgery, screening for Keratoconus, and screening for patients suspected of developing glaucoma.

A tonometry test measures the intraocular pressure (IOP), or pressure inside your eye. This test checks for glaucoma, an eye disease that can cause blindness by damaging the optic nerve in the back of the eye. Tonometry measures IOP by evaluating the resistance of your cornea to pressure. A non-contact tonometry test uses a puff of air to create pressure against your cornea.

A visual field test detects dysfunction in central and peripheral vision due to medical conditions such as glaucoma, stroke, brain tumours, or other neurological deficits. FDT stands for the Frequency Doubling Technology deployed during the test. During a visual field test, flickering targets randomly appear to the patient. Patients click a button each time they see a target.

If a patient currently wears eyeglasses and the prescription of the lenses is unknown by the patient nor the doctor, then lensometry will be performed. A lensometer determines the sphere, cylinder, axis, and prism present in each lens. It also determines the focal power in multi-vision lenses (e.g., bifocals).

A colour blind test determines if you have a colour vision deficiency, or colour blindness. The most widely used screening test for colour blindness is the Ishihara Colour Vision Test, named after Japanese ophthalmologist Shinobu Ishihara. The Ishihara Colour Vision Test consists of a series of coloured plates comprising many dots of various colours, brightness, and sizes. The composition of circles enables a person with normal colour vision to see a single-digit or two-digit number, while a colour blind person will not.

Stereoscopic vision and depth perception testing is important for identifying diseases, such as amblyopia, strabismus, suppression, and stereopsis. Stereoscopic vision refers to how each eye may see an object from different angles but combines these angles to provide a three-dimensional image. During a stereoscopic vision test, the patient tries to identify the "raised" letter, shape, or animal as a means to measure depth perception and to evaluate if the patient's eyes are working together.

For Albertans between of the ages of 0-18 (i.e., children) and 65+ (i.e., seniors), Alberta Health Services covers the cost of one comprehensive eye exam per year along with all medically necessary examinations (e.g., infections, foreign body removal, sudden vision changes, etc.). For Albertans between the ages of 19-64 (i.e., Adults), only medically necessary optometric exams are covered by Alberta Health Services. Adult comprehensive eye exams typically range between $90-160, depending on the number and type of tests/digital scans performed, the advanced technologies (e.g., retinal photography and Optical Coherence Tomography) used to assess patient ocular health, examination length, and overall thoroughness. Several additional tests and scans are required for contact lens wearers and for those that have had corrective eye surgery; therefore additional fees apply.

Depending on the clinic, the number and type of tests/scans performed, the advanced technologies used to assess patient eye health, and thoroughness of the optometrist, an eye exam (including all pre-testing) can take between 10-60 minutes to perform.

Given that individuals only have two eyes, that eye diseases do not produce symptoms until their advanced stages, the importance vision is to quality life, livelihood, and lifestyle, and that once vision is lost it cannot be returned, it is recommended that individuals get an optometrist-performed eye exam annually.

Annual eye exams are especially important for children and seniors, and for those individuals with systemic conditions, such as diabetes.
