At Kirkland Vision Center, we provide technically advanced and comprehensive eye exams to evaluate not just the health of your eyes and the quality of your vision but your overall health. We also use the most technically advanced equipment available including the Humphrey Visual Field Analyzer and the Retinal Fundus Camera.

Depending on your current vision needs, your examination will include the following procedures.

Visual Acuity Test

Eye chart assessment has been a standard vision test for many years. You will be asked to read a projected eye chart to measure your distance vision and a small card chart to measure your near vision.

Cover Test

Another test we use is one that determines how your eyes work together. You will be asked to focus on a small object first at a distance and then close up. You will also be asked to cover each eye alternately while staring at the object.

There is more to this test than meets the eye. We will be observing how much movement or effort each eye exerts when uncovered.

This simple test reveals very subtle misalignments in your binocular vision. Misalignments prevent your eyes from focusing together and can even cause amblyopia or lazy eye. This test is especially important in children’s eye exams.

Slit-Lamp (Biomicroscope) Examination

This magnified, three-dimensional (3-D) view of your eyes is used to determine your overall eye health. We use fluorescein dye drops to assist with observation and better enable us to detect foreign bodies in the eyes as well as infections and injuries.

While you sit comfortably in an exam chair, we will exam the following structures of your eye:

  • Cornea (the clear, outer covering)
  • Drainage angle (where fluid drains from the eyes)
  • Iris (colored portion)
  • Lens (biconvex transparent body behind the iris)
  • Optic nerve (the nerve that transmits visual information from the retina to the brain)
  • Vitreous gel (the fluid in the middle of the eye)
  • Retina (the light-sensitive lining in the back of the eye)

Tonometry (Glaucoma) Test

Tonometry is commonly known as the “air puff” test and is used to determine the intraocular pressure (fluid pressure) inside the eye. Elevated pressure in the eyes can result in glaucoma, a serious condition that causes damage to the optic nerve and, if left untreated, can lead to vision loss.

While you sit comfortably in an exam chair with your chin on a chin rest and your head against a band for proper alignment, an automated discharge of air will contact the surface of your eye. Based upon your eye’s resistance to the puff of air, the tonometer calculates the pressure. This test is painless as only air touches the eye but the sudden burst of air can be alarming. It poses no risk and has no aftereffect.

In addition to using the tonometer machine, we also use an applanation tonometer to determine the force necessary to flatten the corneal surface. In this test, we will use eye drops that numb the eye so you will not experience any discomfort. Then we will examine the eye using a bright-blue glowing probe to manually measure the intraocular pressure.

Both tonometry tests are painless and take just a few seconds to perform.

Humphrey Visual Field Test

The Humphrey Visual Field Instrument is a diagnostic device to test your complete visual field including your peripheral vision.

This simple and painless test exposes the eyes to repeated light stimuli of varying intensities in different areas in the field of vision. The fields are charted based upon your perceptions of the lights and compares those perceptions to the accepted norm for persons in your age range.

The results reveal the amount of visual damage you are experiencing and allow for the early diagnosis and management of a large number of health and neurological conditions including optic nerve damage, intracranial tumors and risk factors for strokes and multiple sclerosis. It is considered the gold standard for managing glaucoma.

Retinal Fundus Camera.

The Retinal Fundus Camera is a low power microscope with a camera that photographs the interior surface (or fundus) of the eye: the retina, optic disc, macula and posterior pole. The use of this technology enables us to monitor your eyes over an extended period and more accurately analyze the progression of disease.

 Pupil Dilation

In order to get a better view of the minute internal structures in the back of your eyes, your comprehensive exam will likely necessitate the use of dilating drops. Dilation is very important for those patients with risk factors and can help diagnosis such conditions as diabetes, high blood pressure, infectious diseases, macular degeneration, retinal detachment, eye tumors and vasculitis.

You should bring sunglasses to your appointment to wear after you leave.

If you require corrective lenses, your exam will also include the following tests to assist in determining the most effective corrective lens prescription for your eyes:

  • Retinoscopy
  • Refraction
  • Autorefractors and Aberrometers
