Routine Eye Exams
Nashua Eye Associates doctors, The Nashua Optical Company, and the Contact Lens Center provide routine eye examinations and services for beneficiaries of most all insurances, including EyeMed and VSP.
The eye is a remarkable anatomic and physiologic structure. A routine eye examination is not only an ocular assessment; a good exam can provide insight into the function of a wide range of the full body systems. For example, a thorough eye exam is also an exam of the neurologic system, the skin, many hormone functions including thyroid and pituitary, the cardiovascular system, and the connective tissue. Eye examination findings have importance well beyond vision; high blood pressure, high cholesterol, diabetes, sickle cell disease, thyroid disease, clotting disorders, carotid artery blockage, and multitude of inflammatory diseases may be diagnosed with the help of an eye exam.
A routine eye exam begins with a measure of visual acuity, as will as a refraction, which is a measure of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The refraction is what is used to generate a glasses or contact lens prescription. Neurologic function is tested by measuring pupil size and reactivity to light, as well as eye alignment and muscle balance. The eye pressure is measured by a painless puff or blue light test, and is an important part of the evaluation for glaucoma. Peripheral vision is assessed to detect vision changes characteristic of optic nerve or brain problems such as stroke. The anatomy of the front part of the eye is evaluated using an eye doctor’s microscope, called a ‘slit lamp’. This includes viewing the lens for cataracts. The posterior part of the eye exam includes examination of the retina, the macula, retinal blood vessels, and the optic nerve.
A routine eye exam sometimes includes a dilated exam, which may allow for a more extensive view of the retina. Typically eye drops are used that last about 4 hours. Dilation causes some light sensitivity, so patients are more comfortable with sunglasses driving home in daylight.
A routine exam may be enhanced by imaging of the retina. Nashua Eye Associates offers Optomap retinal imaging, which is a valuable photographic baseline retina image. The optomap image does not require dilation and becomes part of a patient’s permanent office record. It provides a useful starting point to follow retina, macula, and optic nerve changes that may reflect macular degeneration, glaucoma, as well as other ocular disease.
Patients are asked to bring their current eye glasses to their eye exam. If a patient is unfamiliar with their medications, medication allergies, or medical history, a written summary is extremely useful. Young healthy patients with no history of eye problems can benefit from a routine eye exam every two or three years. Older patients should have an annual exam, as the risk of many common eye diseases increases with age.
