Comprehensive Eye Exam in Bayside, NY

Regular eye examinations are important in maintaining eye health. During a comprehensive eye examination, eye diseases or other abnormalities that are not yet causing symptoms can be detected. Early intervention is crucial in preventing vision loss from a disease such as glaucoma, which may not cause symptoms until significant and irreversible damage has taken place. Early detection of eye problems gives a patient a choice of treatment options, and reduces the risk of permanent damage.

Benefits of a Comprehensive Eye Examination

A comprehensive eye exam should be performed once every year. Children should have regular tests to ensure that their vision is normal so that their schoolwork does not suffer. Older adults are at higher risk for eye conditions such as glaucoma, macular degeneration and cataracts. During a comprehensive eye examination, simple refractive errors are detected, and serious eye problems or diseases, including the following, are diagnosed:

Even in younger, healthy adults who are asymptomatic, a regular eye examination is essential. Serious medical conditions, such as high cholesterol, diabetes and high blood pressure, can be detected, allowing patients to seek treatment early.

The Comprehensive Eye Examination Procedure

A comprehensive eye examination differs from a vision screening. The latter only tests visual acuity, and is commonly performed by a school nurse, optician, pediatrician or other healthcare provider.

In order to evaluate the eyes thoroughly and detect any problems, the following tests are performed:

• Visual acuity
• Visual field
• Retinal examination under pupil dilation
• Slit-lamp
• Tonometry (tests intraocular pressure (IOP))
• Keratometry (measures the curvature of the cornea)
• Refraction

Tonometry checks for the presence of glaucoma, and keratometry for astigmatism. All of the above tests are safe for all patients.

Possible Treatments

Based on the diagnostic findings of the examination, eyeglasses or contact lenses, medication for infection or inflammation, vision therapy, and vitamins or other supplements may be recommended. In some cases, eye surgery may be necessary.

Common Refractive Errors

The most common eye conditions diagnosed during a comprehensive eye exam involve refractive errors that cause blurry vision. These conditions affect millions of people in the United States, and often get progressively worse as patients age. Refractive errors are easily treated.

Myopia: Also known as nearsightedness or shortsightedness, myopia is a condition of the eyes in which nearby objects are clear, and distant objects are blurry. Almost a third of people in the United States have some degree of nearsightedness.

Hyperopia: Also known as farsightedness, hyperopia is a condition of the eyes in which the focus on distant objects is better than the focus on objects closer to the eye, making nearby objects appear blurry. The eye is designed to focus images directly on the surface of the retina; with hyperopia, light rays focus behind the surface of the retina, producing a blurry image.

Astigmatism: Astigmatism occurs when curvature of the eye is irregular. There are two types of astigmatism: corneal, in which the shape of the cornea (the clear covering of the eye) is irregular, and lenticular, in which the lens is imperfectly shaped. Corneal astigmatism is more common. Astigmatism can result in blurred vision at any distance.

Presbyopia: Presbyopia, meaning "old eye," is a condition in which the eyes lose their ability to focus on close objects. It is considered a normal part of the aging process. Symptoms typically begin when patients are between 40 and 45 years old.

All of these vision conditions can be effectively treated with either eyeglasses or contact lenses. Corrective lenses may need to be used only during certain activities, such as reading, watching television or driving, or may be needed at all times.

Comprehensive eye examinations are essential in checking for vision problems, eye diseases, refractive errors and overall health. How frequently the eyes should be examined is based on the patient's age and specific circumstances.
