Dry eye is a very common problem that affects women more than men and becomes more prevalent as people get older.

It can present in many ways, with symptoms that can include a foreign body sensation, burning, stinging, redness, blurred vision, and dryness. Tearing is another symptom and occurs because the eye initially becomes irritated from the lack of moisture and then there is a sudden flood of tears in response to the irritation.

Unfortunately, this flood of tears can wash out other important components of the tear film that are necessary for proper eye lubrication. Signs and symptoms can range from mild to severe.

There are medications that have the potential to worsen the symptoms of dry eye. Here are some of the broad categories and specific medications that have been known to potentially worsen the symptoms:

• Blood Pressure Medications – Beta blockers such as Atenolol (Tenormin), and diuretics such as Hydrochlorothiazide.
• GERD (gastro-esophageal reflux disorder) Medications – There have been reports of an increase in dry eye symptoms by patients on these medications, […]
  

We are frequently asked if it’s wise to have cataract surgery if you have Macular Degeneration.

Let’s start with some background.

1. Cataracts and Age-related Macular Degeneration (AMD) are both leading causes of visual impairment in the elderly population.
2. Cataracts develop when the normal clear lens gets cloudy with age. This is correctable with cataract surgery, which involves replacing the cloudy lens with a clear, artificial lens.
3. While cataracts affect the front part of the eye, AMD causes damage to the retina, which is the inner back lining of the eye.

In the past, there was a concern about cataract surgery causing progression of AMD. It was thought that there was an inflammatory component to AMD and the normal inflammatory response after cataract surgery may lead to AMD progression.

But studies have looked at patients who underwent cataract surgery compared to patients who didn't have cataract surgery and the progression of AMD was not significantly different between the two groups. However, those patients with AMD who underwent cataract surgery had a significant improvement in vision.

One of the hardest questions eye care professionals routinely have to deal with is when to tell people with visual difficulaties that they need to stop driving.

Giving up your driving privilege is difficult to come to terms with if you have a problem that leads to permanent visual decline.

The legal requirements for visual acuity vary from state to state. For example, in New Jersey the legal requirement to drive, based on vision, has been 20/50 vision or better with best correction in one eye for a “pleasure” driving license. For a commercial driving license, the requirement is 20/40 vision or better in both eyes.

In some states there is also a requirement for a certain degree of visual field (the ability to see off to the sides).

According to the Insurance Institute for Highway Safety, the highest rate of motor vehicle deaths per mile driven is in the age group of 75 and older (yes, even higher than teenagers). Much of this increased rate could be attributable to declining vision. There are also other […]

We have all heard the term ”Love is in the Air,” but can love really be in the eyes? Actually, Science has proven it so. Certain chemicals (or endorphins) that produce the emotion of love can be emitted through emotions expressed in the eyes. There are physiological changes in the eyes that occur when love is expressed between two individuals. Love for a romantic partner, a family member, or a favorite pet can all cause the same physical response: the pupil (black part in the center of the eye) dilates.

The size of the pupil can be an indication of emotional responses and messages. According to Scientific American, the autonomic nervous system (ANS), which directs our fight or flight response, causes the pupil to have a quick dilating response. The ANS is also in charge of heart rate and perspiration, and when a person is extremely interested in another person, the pupil has a dilating effect that is slightly less than the pupillary light reflex. This bounce in size is an automated response that gives scientists indication of […]

It's pretty common for eye doctors to have older patients come in asking if the white part of their eye, the sclera, has a growth or is turning a gray color.

Usually, the culprit is senile scleral plaque, which is commonly seen in people over the age of 70. It is a benign condition and more commonly seen in women.  This condition is symmetrically found on both sides of the eye and is due to age-related degeneration and calcification of the eye muscle insertion into the eye.  In one study, the size of the senile scleral plaque increased as the person aged and was not associated with any medical conditions.  People are asymptomatic, as the plaques do not affect vision and no treatment is needed.

Another commonly asked question is: Why is the colored part of my eye turning white?  

The colored part of the eye is the iris, which is covered by a clear layer called the cornea.  It is actually the edge of the cornea that attaches to the white part of the […]

Recent Census Bureau data shows a population of approximately 71 million baby boomers (the generation born from 1946-1964). What does that have to do with low vision you may ask? Approximately 40 million people worldwide have some sort of blindness, and aging increases the incidence of macular degeneration and other vision impairment that qualifies them as “low vision” persons.

Low vision is a condition of the eye in which the vision falls below 20/70 in the better seeing eye. It impairs the recipients, rendering them unable to perform daily tasks that others take for granted. With this rising aging population, the awareness of low vision therapy, diagnosis, and treatments are more widely available.

Low vision treatment can help people recover from decreased visual function due to retinal disease, brain injury, neurological damage, and other causes.

It is not only the elderly population that is affected–approximately 20% of low vision patients are children under the age of 18. Childhood genetic disorders of the eye such as retinitis pigmentosa, albinism, Bests disease, ROP, rod/cone disorders, and glaucoma are […]

When confronted with a diagnosis of Age Related Macular Degeneration (AMD), it's natural to wonder what you should do.  Here are some treatment options for both Dry and Wet Age Related Macular Degeneration.

Dry AMD Treatments

Nutrition Supplements

The Age-Related Eye Disease Study 2 (AREDS2) showed that people at high risk of developing advanced stages of AMD benefited from taking dietary supplements. Supplements lowered the risk of macular degeneration progression by 25 percent. These supplements did not benefit people with early AMD or people without AMD.

Following is the supplementation:

• Vitamin C – 500 mg
• Vitamin E – 400 IU
• Lutein – 10 mg
• Zeaxanthin – 2 mg
• Zinc Oxide – 80 mg
• Copper – 2 mg (to prevent copper deficiency that may be associated with taking high amount of zinc)

Another study showed a benefit in eating dark leafy greens and yellow, orange and other fruits and vegetables. These vitamins and minerals listed above are recommended in addition to a healthy, balanced diet.

It is important to remember that vitamin supplements are not […]

There have been studies undertaken over the past several years to try and understand if there are any of our day-to-day activities that either help or hurt the management of glaucoma.

Most of the studies demonstrated very little impact on the course of glaucoma. Here are some of the things researches have looked at.

Aerobic exercise: This means doing something at least four times per week for more than 20 minutes at a time that raises your pulse rate to a level that makes your heart work harder. Going from a sedentary lifestyle to active one with aerobic exercise resulted in a very slight decrease in baseline eye pressure.

Yoga: A study conducted at the Mount Sinai Health System (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144505) showed a significant increase in eye pressure with any head-down positioning. People with glaucoma would be wise to avoid any exercise that involves a position where your head is lower than your heart.

Weight lifting: Holding your breath while exerting yourself (called the Valsalva maneuver), is also a time when your eye pressure can go sky high. […]
