Periodic eye and vision exams are an important part of preventive health care. Many eye and vision problems have no obvious signs or symptoms and patients are unaware that problems exist until the conditions reach later stages. Early diagnosis and treatment of eye and vision problems by our doctors at the New Jersey Eye Center can allow you to maintain good vision and eye health. In certain cases this can prevent vision loss. Individual patient signs and symptoms, along with the professional judgment of our doctors, significantly influence the types of tests we will recommend to perform.
A comprehensive adult eye and vision examination may include, but is not limited to, the following tests:
Obtaining a thorough patient history helps to uncover any symptoms you may be experiencing and when the symptom(s) began. We also ask for the presence of any general health problems and medications taken to better diagnose any eye condition. We would like to know about any occupational or environmental conditions that may be affecting your vision. Our doctor will ask about any eye or vision problems you may be having and about your overall health, including previous eye conditions amongst family members.
Visual acuity measurements are taken to find out the clarity of your vision in both eyes. As part of the test, which you have probably taken before, we ask you to read letters from near & far charts. If the results of visual acuity testing for distance vision are 20/50, for example, it means that you will need to be at about twenty feet away from a letter to be able to read it, while a person with ideal vision can read it from a distance of fifty feet. When you hear a person has 20/20 vision, it means he/she has clear vision without glasses or contact lenses.
Preliminary testing usually include evaluation of specific aspects of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils respond to light.
We use this test to measure the curvature of your cornea by focusing a circle of light on it and measuring the reflection. Keratometry helps our doctors to find a contact lens that would best fit the specific shape of your eye.
This testing helps us to identify the appropriate lens power needed to compensate for any refractive error – most people suffer from one or a combination of nearsightedness, farsightedness, and astigmatism. Our doctor will place an instrument that contains a series of lenses in front of your eyes to determine which will give you the best corrected vision. In some cases we use another instrument that automatically evaluates the focusing power of the eye. This testing is often done without eye drops to determine how the eyes respond under normal seeing conditions.
These tests allow our doctors to see how well the eyes focus, move and work together. This testing looks for problems that keep your eyes from focusing effectively or situations where the patient has a difficulty in fully using both eyes at the same time.
Tonometry is a test that measures the pressure inside your eye. Elevated pressure can mean a higher risk to develop glaucoma. We will also perform external examination of the eye, including an evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue using bright light and magnification. Our doctors will also evaluate the lens, retina and posterior section of the eye through a dilated pupil that will allow them to better see the internal structures of your eye.
Additional tests may be needed based on the results of the previous steps to confirm or rule out possible problems, to clarify uncertain findings, or to provide a more in-depth assessment. In some cases we will recommend special examinations to diagnose glaucoma or diabetic retinopathy. At the end of all examinations, our doctor will assess and evaluate the results, offer a detailed diagnosis and develop a treatment plan that matches your individual eye conditions.
