Eye Examinations


Complete Eye Health Examinations are provided by Doctor Day and his Clinic Technicians. We use the latest instruments to ensure the best patient care possible. Through a series of tests, Doctor Day evaluates corrective needs along with complete eye health. He will examine your retina, optic nerve, macula, blood vessels and vitreous by utilizing the retinal scan (Eyescape) or dilation drops. He is also evaluating the surface of the eye for: dryness, disease, irritation, the eyelids, lashes and tear ducts to determine if there is any possible impairment to your eye health & vision clarity.


Yearly and bi-yearly eye examinations are necessary for all. Having 20/20 or better visual acuity, is not an indication that other eye health issues do not exist. Unlike the rest of the human body, the eyes rarely hurt when something is wrong. Glaucoma, Macular Degeneration and Diabetic Retinopathy for instance are all very serious eye conditions that generally are pain free and, if not treated in early stages, can cause irreversible and life-changing vision loss. The only way to catch these, and many more serious eye conditions at early stages, is to follow the Doctor's recommendation for yearly/bi-yearly eye health examinations.


Typically eye exams include:
 
Medical / Health History
Measurement of visual acuity
Pupil dilation or EyeScape (to evaluate the health of the eyes)
Intraocular pressure (a Glaucoma screening test)
Blood pressure
Visual field test
Analysis
Diagnosis
Prescription (lenses or medication) 


 



Digital Retinal Scan

 

The Digital Retinal Scan is advanced digital imaging that allows for a thorough retinal evaluation. By taking a digital fundus photo of the back of the eye, Dr. Day can detect and monitor ocular health by capturing a clear view of the optic nerve, blood vessels, macula and fovea. These images are stored and serve as a baseline measurement for future comparison. These photos will be kept as a permanent record allowing Dr. Day to view in detail the general health of the internal portion of the eye. This can be key to detecting Glaucoma, Macular Degeneration, Diabetic Retinopathy, High Blood Pressure, elevated Cholesterol, Retinal detachments and many more eye issues detectable at very early stages.

 

At this time a digital retinal scan costs $39.00 per patient. When considering that 90% of the time, electing for EyeScape will do away with the need to fully dilate your eyes, it is well worth the extra cost! This means you leave our office without the sensitivity and slightly blurred vision dilation drops can cause.

Children's Eye Examinations
 

Children’s Eye Examinations are provided in combination by Dr. Day, and his Clinic Technicians. Dr. Day along with the American Optometrist Association, recommends getting a child's' first eye examination as early as 6 months old (earlier if a problem is suspected) and no later than when the child starts Kindergarten. Sitting very close to a TV screen, shorter attention span, and difficulty learning can be signs of vision problems that parents often do not notice or attribute to poor vision. Also, more noticeable signs, such as a crossed or lazy eye need to be addressed early in development in order to have effective treatment.  

 

Dr. Day has fun, child friendly eye tests, as well as a wonderful selection of children’s frames. Please call East Main Vision Clinic to schedule your child’s eye examination today!
 


 

Findings from your Examination

 

What is 20/20 vision?

"20/20 vision" is commonly accepted as the standard of normal distance vision for a human being. Basically it means "good visual acuity at 20 feet." So if your vision is 20/20, you can read certain sizes of letters on a Snellen chart clearly at 20 feet or closer. But if your friend has 20/15 vision, his visual acuity is better than yours: you would have to stand 15 feet away from the chart to read the smaller letters that he can read while standing 20 feet away. Conversely, someone with 20/30 vision has worse distance vision than you.
 

By the way, visual acuity at a distance isn't the only measure of how good your vision is. You could have 20/20 distance vision but still have difficulty seeing at night because of poor contrast sensitivity. Or you could have near vision problems because you're over 40 and experiencing presbyopia.
 

MYOPIA or Nearsightedness

Myopia occurs when an eye is too long for the cornea's curvature. As a result, light rays entering the eye do not come to a sharp focus on the retina at the back of the eye. Instead, they focus further forward, producing a blurred image. People who are highly myopic have an increased risk of a retinal detachment resulting from the "pulling" on the retina.
 

HYPEROPIA or Farsightedness

Hyperopia occurs when an eye is too short for the cornea's curvature. As a result, light rays entering the eye focus behind the retina instead of precisely on the retina, and a blurred image is produced. A person with hyperopia cannot see distant objects clearly. 
 

ASTIGMATISM or "Football-shaped" Cornea

Astigmatism is the result of having a cornea that is irregular in shape. The cornea is normally round. An astigmatic cornea is oblong or "football" shaped, resulting in a condition that generally causes eyestrain, headaches and blurry vision. Astigmatism is often associated with nearsightedness and farsightedness and is not considered a medical problem. 
 

PRESBYOPIA

Presbyopia is a condition in which the focusing ability of a person's eyes has decreased to the point where vision at his reading distance becomes blurred and difficult. You may  begin to notice early signs of Presbyopia around the age of 40.
 

Eye health concerns noted:

 

CATARACTS

A Cataract is a clouding or opacity of the natural internal lens of the eye, which causes a visual impairment.
The natural lens is located behind the iris, or "colored part" of the eye. The opacity may be a small dot or may involve the entire lens. The opacity in the lens causes the light entering the eye to be scattered, causing images to appear hazy or blurred. If your cataract is advanced, Dr. Day may suggest a surgical evaluation.
 

GLAUCOMA OR GLAUCOMA SUSPECT

Glaucoma is an eye disease in which pressure increases in the eye due to clogged or blocked passages. Fluid that normally drains through these passages begins to build up, and the increased pressure can damage the optic nerve. Open-angle glaucoma tends to develop without warning--often painlessly and with no symptoms. Because of this, it can cause damage and blindness more quickly when untreated. Risk factors for developing glaucoma include people over the age of 40; those who have a family history of glaucoma; those who are very nearsighted; diabetics; and African-Americans.
 

MACULAR DEGENERATION

The most common symptom of macular degeneration is blurred central vision; noticeably worse when reading. In addition, horizontal lines may appear wavy and/or distorted. The most common method of detecting macular changes is the Amsler Grid test. During an eye examination, you are asked to look at the grid's center dot and asked if you notice any wavy, distorted, missing, or broken lines on the grid. Any one of these irregularities may indicate changes within the macular region of the eye. Your ophthalmologist or optometrist will be able to confirm any suspicions of macular degeneration during a dilated retinal examination.
 

DRY EYE DISEASE

There is no known cure for dry eye. However, some dry eye symptoms are caused by medications, eye infections or wearing contact lenses. In these cases, simply eliminating the cause of dry eye will stop the problem. In many cases, however, dry eyes are a lifelong problem. You can relieve the symptoms, but not cure the original cause. Most eye care specialists recommend artificial tear products (ocular lubricants) for their patients with dry eyes. Follow your eye care specialist's recommendations in order to effectively relieve dry eye symptoms and avoid further damage to your eyes.
 

DIABETIC RETINOPATHY OR OTHER DIABETIC ISSUES

Diabetic Retinopathy is condition where a diabetic persons blood sugar gets too high. When this occurs, the high blood sugar level starts a series of events which end in damaged blood vessel walls. Blood vessels in the eye are small and delicate. As such, the blood vessels in the eye are easily damaged. The damaged vessels can then leak fluid or bleed, causing the retina to swell and form deposits known as exudates.
 

HYPERTENTION OR OTHER HIGH BLOOD PRESSURE ISSUES

Hypertension, or high blood pressure, is a disease that can have serious effects on many parts of the body, including the eyes. Hypertension causes damage to the tiny and fragile blood vessels that feed the retina.

What can be done? To reduce the risk of hypertensive eye disease, regular examinations by a physician are needed to monitor the condition. Hypertension must be controlled as much as possible and the key to control is to follow the advice of your physician.
