Glaucoma can have many causes. Some are common knowledge, such as cataracts and complications from high blood pressure or diabetes, but others can be surprising. Different types of eye injuries, OTC or prescription steroids, and eye melanomas can also cause you to develop this dangerous eye disease.
As we age, gravity affects every part of our body, even the skin and muscles of our eyes. The skin around our eyes loses elasticity and the muscle tone in our eyelids decreases. Over time, this may result in droopy eyelids, or ptosis.
The muscle that lifts the eyelid is called the levator muscle, and when it stretches or weakens it becomes harder to keep the eyes fully open. This may occur in one or both eyelids as we age. However, age is not the only cause of droopy eyelids. Ptosis can also be congenital when the levator muscle fails to develop properly in utero, as was the case with the famous actor, director, and producer Forest Whitaker.
In addition, medical conditions such as an eye injury, nerve damage, or tumors can cause the upper eyelid to droop lower than normal. Regardless of the cause, droopy eyelids are not just a cosmetic concern. If a droopy eyelid covers part of your pupil, then your vision will be affected. Ptosis can restrict or even completely block normal vision. (more…)
Your cornea is the clear, round dome that covers the eye’s iris and pupil. When there’s an imperfection in the curvature of your cornea, it’s called a corneal astigmatism. When the shape of your eye’s lens is distorted, it’s called a lenticular astigmatism.
Ideally, the cornea and lens are both smooth and curved symmetrically in all directions, which helps your eye focus, or refract, light rays sharply. But with either type of astigmatism, light rays are not refracted properly, so your vision for both near and far objects appears blurry or distorted. Objects may be blurry or appear to be taller, wider or thinner than they actually are.
Astigmatisms are common, but they’re also one of the most misunderstood refractive disorders. In addition to blurred or distorted vision, astigmatism can cause eye strain and headaches after prolonged periods of visual stimulation, such as from reading a book, looking at electronic screens, or watching a movie.

Detecting eye diseases as early as possible gives you the best chance of saving your sight. Some of the most common eye diseases can blind you before you ever notice the first symptoms.
The American Academy of Ophthalmology recommends that you get a comprehensive eye examination at age 40, which is when changes in your vision or early signs of disease typically begin. A comprehensive screening, which includes dilating the eyes, can help identify signs of eye disease at an early stage. Continue to have a comprehensive eye exam at least every two years after age 40, and at least once a year after age 50. (more…)
When it comes to preserving your eyesight, being proactive rather than reactive makes all the difference. Regular eye examinations are often put off until our vision becomes blurry or our eyes hurt or we have some other issue with our eyesight. But even if your vision seems perfectly fine, routine eye examinations are vitally important because they are often the only way to detect many of the worst eye diseases before they have robbed you of your sight.
Dr. Marc Bodenheimer says, “A lot of times, people will come in when they’re having problems and find out that if they’d come in two or three years sooner we could have kept them from having these problems. It makes it much more difficult to treat those problems at that point.” (more…)
March madness may be behind us, but one thing about the game is still a slam-dunk—basketball remains the leading cause of sports related eye injuries. As reported in the journal Pediatrics, basketball related eye injuries lead to the most emergency room visits among kids under the age of 17 in the U.S. Following closely behind are eye injuries sustained while playing baseball, softball, and from using non-powder guns, such as pellet guns or airsoft rifles. The most common types of eye injury for these activities are corneal abrasions.
But basketball related eye injuries certainly aren’t limited to kids or amateurs. Consider these scenarios:
With East Tennessee’s allergies kicking back into gear this spring, many people are wondering how to tell the difference between two of the most common eye related issues—ocular allergies and dry eye. If your eyes are red, itchy, burning, or gritty-feeling, it’s important to get to the root cause.
While some symptoms of dry eye and allergies are similar, there are clear distinctions between how to treat the two eye conditions. And actually, you can suffer from both ocular allergies and dry eye simultaneously. Let’s take a closer look at both conditions: (more…)
Many eye diseases have no early warning signs or symptoms, but a comprehensive eye exam can detect eye diseases in their early stages, before vision loss occurs. Early detection and treatment of any eye disease is the key to preventing vision loss, and ophthalmologists are trained to evaluate your eyes to degrees that go well beyond whether or not you need glasses.

March is Workplace Eye Wellness Month and, according to the American Academy of Ophthalmology, nearly 25,000 Americans visit the emergency room each year due to a workplace eye injury. In fact, the U.S. Department of Labor reports that eye injuries alone cost more than $300 million per year in lost production time, medical expenses, and worker compensation. Welders, construction workers, electricians, plumbers, and pipefitters are at the highest risk for workplace eye injuries.
Eye injuries range from scratches to severe trauma that can cause permanent damage, vision loss, and blindness. Common causes of workplace eye injuries include:
