Generally, dilation of the pupil will last for three to six hours and will primarily affect your near or close up vision. However, it is not uncommon for dilation to last up to 24 hours for some patients depending on the eye drops used to achieve dilation. Different eye drops are used for various ages of patients. Most patients can drive home after their eye exam, and sunglasses are encouraged to be worn. Disposable sunglasses are provided for those patients who do not have sunglasses.

The macula is important to eyesight since it is the part of the eye responsible for detailed central or "straight ahead" vision. Although people with AMD rarely go completely blind because of this condition, they may find it difficult to read, recognize faces or colors, drive, and perform other daily functions that require central vision.

Driving laws vary from state to state and from country to country. In the State of Florida, drivers must have at least 20/40 vision in both eyes, with or without corrective lenses. If vision is 20/200 or worse in one eye, drivers must have 20/40 vision or better in the other eye. A doctor's referral may be required. For most people, diagnosis of cancer creates emotional distress. Fear of treatment and fear of the future can produce apprehension, anxiety, confusion and depression.

The eye has an internal pressure created by production of a clear fluid called aqueous humor. This fluid circulates through the eye and exits through the anterior chamber angle and ultimately drains into the blood stream. In glaucoma, the aqueous humor outflow is obstructed, resulting in increased eye pressure and, eventually, optic nerve damage.

Diabetes, a disease that prevents your body from making or using insulin to break down sugar in your bloodstream, can cause changes in nearsightedness, farsightedness, and premature presbyopia. In fact, the early signs of diabetes are often detected during eye examinations. Diabetes can lead to cataracts, glaucoma, and decreased eye-muscle coordination and cornea sensitivity.

This is when the esophagus enlarges over time, and is probably related to either too tight a Band, or possibly improper placement of the Band around the junction of the esophagus and stomach. This requires loosening or removal of the Band.

A hurricane may sustain an eye for several days. How long one might be in the eye if one were sitting in one place as the hurricane passed over, is a function of two things: How fast is the hurricane moving? Most hurricanes may move along at 10-20 mph, but in extreme cases, they could be moving as fast at 40 mph (pretty rare), or go much more slowly, or even stall out (“quasi-stationary” as they are called).

Please allow approximately two hours for the initial low vision evaluation. At that time an initial treatment plan including any recommended low vision devices will be discussed. Follow-up visits are scheduled on an as needed basis. Yes. Medicare considers a large portion of a low vision examination optical evaluation (or refraction).

Once the phase of eyesight loss is over, the eyesight usually stays the same. The loss of eyesight usually progresses rapidly over a period of

Cotton Wool Spots -- The most common eye problem from AIDS doesn't threaten vision. Your eye has an inner layer called the retina, which sends images to the brain and helps us see. AIDS can cause tiny amounts of bleeding and white spots in the retina. These white spots are called "cotton wool spots" because of the way they look. CMV Retinitis -- A serious eye infection of the retina is caused by CMV, the Cytomegalovirus (CMV). About 20-30% of people with AIDS have CMV.

Blue light is the shortest visible wavelength, and because of this, it is easily scattered and reflected. By wearing quality sunglasses, which absorb and block blue light before it reaches the retina, blue light is never allowed to cause distortion.

The human crystalline lens is a clear, flexible substance in the normal eye. It is situated just behind the pupil and constitute one of the main elements that focus incident light onto the retina. A cataract means the clouding or opacification of the crystalline lens which in most cases is due to aging. When a cataract is formed, the incident light become scattered or blocked, causing blur images on the retina hence poor vision.

Normally the images sent by each eye to the brain are identical. When they differ, double vision occurs. Rather than go through life with double vision, the brain soon learns to ignore the image sent by one and decides to "see" only with the good eye. The eye that is ignored becomes weaker from disuse.

Recent evidence suggests that open angle glaucoma is also part of NPS. Open angle Glaucoma is a condition caused by progressive blockage of the outflow of fluid from the front chamber of the eyes which can result in elevated intraocular pressure leading to narrowing of the visual field (tunnel vision) and eventually blindness if left untreated. Other ocular abnormalities occasionally associated with NPS include Keratoconus, Microcornea, Microphakia, cataracts and Ptosis.

Ocala Eye, we currently use the VISX S4™ Excimer Laser with pupil tracking. This laser uses Fourier Wavefront™ analysis and treatment, the most sophisticated Wavefront™ algorithm available in the U.S. today. The laser is kept in a dedicated laser suite with computerized climate control, constantly monitoring temperature and humidity to ensure the highest possible accuracy in our treatments.

A regular eye exam concentrates on diagnosing eye disease. A low vision exam focuses on designing specialized glasses and low vision devices to enhance remaining vision. A low vision exam, sometimes called a functional vision assessment, evaluates vision functioning and the effect it has on daily living activities, such as reading the newspaper or cooking. After an interview helps to determine the person's visual goals, a low vision specialist performs a detailed visual analysis.

This is a great question to answer for our patients who are already shopping at Costco or have a busy day and want to fit in an eye exam. Usually, from start to finish, your time with us will take 20-40 minutes. To see what is included in a comprehensive eye exam, see here. We have you fill out some simple paperwork, go through some pre-testing with our friendly office staff (Judy or Lisa) and then you meet with Dr. Hirano for the rest of your eye exam.

Amblyopia can cause blindness and brain damage if not treated. Some of the related conditions include anisometropia, where one eye is very near-sighted or far-sighted; strabismus where the eyes are misaligned or crossed; and media opacities where light is blocked, as in cataracts. Other eye conditions that can be identified with the PhotoScreener™ include hyperopia (far sightedness), myopia (near sightedness) and astigmatism.
