VISUAL EXAMINATION AND SPECIALIZED TESTING

Here’s a brief guide to the special eye tests your eye doctor may perform during an eye exam. In addition to a complete examination of your eye, your doctor may want to perform one of the following eye tests.

Glaucoma Testing (Applanation Method)

This eye test helps doctors diagnose glaucoma by measuring the amount of pressure needed to flatten a portion of the cornea. This is done by taking a thin strip of paper stained with the dye fluorescein. This dye stains the front of the eye and enables a better eye exam by the doctor. The patient is then given a local anesthesia in the form of drops and the pressure is measured using a tonometer.

Icare Tonometer

The Icare tonometer is the new technology being used now at Eye Associates to measure intraocular eye pressure.  The Icare tonometer does not require an anesthetic eye drop for the testing and there is no abrupt air puff used to get a reading.   The doctors of Eye Associates are happy that there is now a better alternative and is so much more comfortable for our patients to experience in our office.

Corneal TopographyCorneal Topo

During this eye test, a computer is used create a “map” of the curvature of the cornea. The computer analysis will show any distortions of the cornea such as scarring, as well as conditions such as astigmatism. This eye test is used to screen patients before they undergo any refractive surgery, as well as for fitting contact lenses and corneal transplants.

Fluorescein Angiogram Flour

This is an eye test used to evaluate the blood circulation in the retina. It is useful in helping diagnose diabetic retinopathy and retinal detachment. During this eye test, a special dye, called fluorescein, is injected into a vein in the arm. The dye quickly travels to the blood vessels inside the eye. Once it reaches the eye, a specialized camera equipped with special filters that highlight the dye is used to photograph the fluorescein as it circulates though the blood vessels in the back of the eye. This will enable the doctor to diagnose any circulation problems, swelling, leaking or abnormal blood vessels. If you need this procedure we will refer you out to our Retina Specialist.

Pupillary Dilation Test

During this eye test, the eye doctor places special drops in the eye that cause the pupil to dilate (expand). By dilating the pupils, your doctor can examine your retina for any signs of disease.

Refraction TestPhoropter

This eye test measures your ability to see objects at specificdistances. Often doctors will ask the patient to look at a chart, usually 20 feet away, and try to read it while looking through a special instrument known as a phoropter. The phoropter moves lenses of different strengths into place for the patient to look through. The doctor will ask you which of the choices looks clearer and based on these answers will determine the appropriate prescription needed for glasses or contacts. This eye test is useful in helping to diagnose presbyopia, hyperopia, myopia, and astigmatism.

Slit-lamp Examslit lamp

This eye test looks at the front of the eye by shining a beam of light shaped like a small slit on the eye. The eye doctor may also dilate your pupils while you are undergoing this eye exam. The eye test can be used to help diagnose cataracts, retinal detachment, macular degeneration, injuries to the cornea and presbyopia.

Tonometry

An eye test used to help diagnose glaucoma in which a small, smooth instrument known as a tonometer is lowered onto the surface of the eye in order to measure the pressure in the eye. Other methods of measuring eye pressure can also be used. The “air puff” tonometer measures the eye pressure indirectly by the eye’s resistance to a puff of air. It is less accurate but does not require anesthetic eye drops.

Ultrasound

An ultrasound eye test uses sound waves to provide a picture of the eye’s internal structure. It is useful in evaluating ocular tumors as well as the retina when it is being obscured by cataracts or a hemorrhage. This eye test will be given as part of preoperative evaluation for cataract surgery.

Visual Acuity Testing Snellen

A test of your visual acuity, or ability to see sharply and clearly at near and far distances, will be performed. Various eye tests can be used to determine the visual acuity of infants, children, and adults. These are fairly simple and can be performed by an ophthalmologist, optometrist, technician, nurse or optician. They do not, however, test for important functions of sight, like depth perception or color blindness. One common type of eye test used for children who cannot yet read is the Random E’s Visual Acuity Test. The patient is asked to identify the direction that the letter “E” opens to by holding out 4 fingers to mimic the letter “E.” This eye test is safe, there are no risks involved, and it works just as well as most other eye tests.

Visual Field Test Visual Field

A test used to measure peripheral (side) vision. When given this test, you will be asked to stare at on object in the center of your line of vision (either the doctor’s eyes, on a screen or using a computer program). As you are looking at the object, you will be asked to note when you see an object moving into your peripheral vision. This test is done to diagnose glaucoma or possible damage caused by a stroke.

GDX HRT RTA and OCT 

These technologies are used to help diagnose and treat many eye diseases, specifically Glaucoma and retinal disorders. This technology uses laser scans of the back of eye to accurately diagnosis eye diseases.

Retinal PhotographyREtina

We offer our patients access to one of the most informative diagnostic tools, the retinal photo.The detailed view of your retinal blood vessels it provides, helps us to rule out pathological changes due to high blood pressure; athero-sclerosis due to cholesterol plaque formation; sight-threatening diabetic changes; and other general health conditions. The photo also provides a magnified image of your optic nerves and maculae, which facilitates the diagnosis of glaucoma and macular degeneration in their early, most treatable stages. Small tears in the retina (which can usually be easily sealed with a laser) can also be detected before they progress to more extensive retinal detachments requiring surgery.   A baseline photo is recommended for all patients.

Corneal PachymetryC Pach

Corneal pachymetry can aid in the diagnosis of corneal thinning and is helpful to assess the function of the corneal endothelium (posterior layer of the cornea). This test is useful in assessing a patient’s eligibility for refractive surgery. Recently, corneal thickness has also been found to be useful in interpreting intraocular pressure.

Contact LensesContacts

Many changes have recently taken place in the contact lens industry. The biggest advance is the introduction of silicone plastics. Even though silicone materials have been around for some time, they didn’t work well for soft contact lenses because the stiffness of the plastic and the surface dryness lead to discomfort. The biggest advantage of silicone materials is that they allow a great deal of oxygen to flow through them. Just recently, lens manufacturers have developed ways to make them less stiff and more wettable, which makes them more comfortable.

The new Oasys lens from ACUVUE may be the best of the new wave of silicone soft contact lenses. Smooth and soft, many patients can hardly feel it when it’s on!

We have disposable lenses to correct astigmatism, bifocal, eye color enhancing , 1 day disposable and 30 day continuous wear. So whether you are an occasional wearer, new to contacts, require them for athletics, there are probably a type to fit your needs. Disposable lenses require less care and maintenance and afford the wearer the healthiest and most convenient way to wear contacts.

We carry specialty contact lenses such as: Bifocal, astigmatic, 30 day continuous wear, aspheric, gas permeable, 1 day disposable, keratoconus, post surgical, hard to fit, monthly and bi-monthly replacement.

Medical Eye Treatment

For most eye disorders such as: Pink eye, Glaucoma, Uveitis, Iritis, Dry eyes, Allergic Conjunctivitis, Blepharitis, Keratoconus and many more.

What is Laser Vision Correction?

It is a treatment designed to permanently reduce dependence on glasses or contact lenses for people whose eyes are nearsighted, farsighted, and/or astigmatic. A cool laser beam is used to reshape the cornea to improve the focusing ability of an eye.

Am I a Candidate for Treatment?

About seven out of ten people who wear glasses and/or contact lenses are candidates for laser vision treatment. You are a likely candidate if:

  • You have healthy eyes
  • You see clearly when you use your glasses and/or contact lenses
  • Your vision has been stable for a year

You fully understand the risks and benefits of treatment

The doctors and staff at Eye Associates have extensive laser vision co-management experience. We evaluate your eyesight to help you and the surgeon determine if laser vision correction is right for you. We work very closely with the surgeon before and after your treatment to achieve the best results possible. We do all of the pre-op and post-op procedures in our office. Usually, the only day you need to go anywhere else is on the day of your laser treatment, when you visit the nearby laser center.

What Testing is Involved?

  • Advanced Corneal Topography – This is a computerized mapping system of the cornea which takes over 8000 data points in a 12mm area. We do this test multiple times before and after laser vision correction to make sure your corneal shape is stable and distortion-free.
  • Corneal Pachymetry – This is an instrument which allows us to measure your corneal thickness in microns. With LASIK surgery, you must have adequate corneal thickness throughout the treatment zone in order to avoid problems in the future.
  • Comprehensive Pre-surgery Counseling and Testing – This includes an in-depth discussion of laser vision correction options and alternatives to laser treatment. It helps you make the right decision based upon honest assessment and realistic expectations.
