In 2020, Alzheimer's Disease International estimated that the number of people living with dementia worldwide – nearly 55 million in 2020 – will almost double every 20 years.

There is no single test that can show if a person has Alzheimer's, but doctors can almost always determine if a person has dementia, although it may be difficult to determine the exact cause. Diagnosing Alzheimer's requires careful medical evaluation, neurological testing, and sometimes brain imaging and blood tests to rule out other causes of dementia.

Most of the testing for early disease – MRI scans of the brain, brain PET scans looking for amyloid, and spinal taps looking for certain proteins in the spinal fluid – are not very accurate, and they are invasive and often expensive.

A few years ago, researchers have turned to findings in the eye to help with early detection and are hoping to find ways to make the diagnosis earlier when potential treatments may have a better outcome. There is also hope that these tests will be less expensive and invasive then the other options.

Have you ever wondered what happens to the visual system as we age? What does the term "second sight" mean? What is presbyopia? What are the eyes more susceptible to as the aging process occurs? What can be done to prevent certain aging factors of the eye? The answer lies in a theory known as apoptosis (no that's not the name of the latest pop artist).

Apoptosis is the pre-programmed life of every cell in our body. Most studies show that it's a function of our programmed DNA. It's the ability for cells to survive and thrive in the anatomical environment. The body's ability to withstand and thrive during the aging process depends on proper nutrition, good mental health, exercise, and adequate oxygen supply. That's why studies have shown smoking can shorten your life by a decade or more.

In regards to aging and the eye, there is a phenomenon during the 6th to 7th decade of life called "second sight."   This is simply progressive nearsightedness in older […]

We all know that during pregnancy, a woman's body goes through a great deal of change hormonally and physiologically.  But did you know her eyes change as well?  Below are some of the most common effects pregnancy can have on the eye.

• Corneal changes. In some cases, pregnancy can cause the cornea, the front window of the eye, to change curvature and even swell, leading to shifts in glasses and contact lens prescriptions. In addition, changes in the chemistry of the tear film can lead to dry eyes and contact lens intolerance. It is for these reasons that it is generally not recommended to have any new contact lens fitting or new glasses prescription checks until several months postpartum. We want to get the most accurate measurements possible.
• Retinal changes.  Many different conditions can affect the retina during pregnancy. If the pregnant woman has diabetes, diabetic eye disease can progress by 50%. In women with preeclampsia, a condition where blood pressure rises significantly, over 40% of women can show changes in the retinal blood […]
  

1. Vision is so important to humans that almost half of your brain’s capacity is dedicated to visual perception.

2. The most active muscles in your body are the muscles that move your eyes.

3. The surface tissue of your cornea (the epithelium) is one of the quickest-healing tissues in your body. The entire corneal surface can turn over every 7 days.

4. Your eyes can get sunburned. It is called photokeratitis and it can make the corneal epithelium slough off just like your skin peels after a sunburn.

5. Ommatophobia is the fear of eyes.

6. You blink on average about 15 to 20 times per minute. That blink rate may decrease by 50% when you are doing a visually demanding task like reading or working on a computer – and that’s one reason those tasks can lead to more dry-eye symptoms.

7. Your retinas see the world upside down, but your brain flips the image around for you.

8. If you are farsighted (hyperopia) your eye is short, and if you are shortsighted (myopia) your eye is long.

9. An eyelash has […]

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

Signs and symptoms can range from mild to severe.  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.

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, which include Cimetidine (Tagamet), Rantidine […]
