Outdoor Caution

Eye On Your Health

Outdoor enthusiasts know that it is important to wear sunglasses that protect the eyes from the sun’s ultraviolet rays. Sailors, golfers, and other outdoor enthusiasts should also know that wraparound sunglasses help protect the eyes from developing a non-cancerous growth that often occurs among those who spend excessive amounts of time in sunny, sandy, dusty, windblown areas. A ‘’pterygium’’ is a raised triangular growth of abnormal tissue that forms on the thin tissue (conjunctiva) that covers the white part of the eye, most commonly on the nasal side. While no treatment is usually necessary, a developing pterygium may block vision and even alter the shape of the cornea to cause astigmatism. If so, it should be surgically removed.

Twitching’s Off Switch

Eye On Your Health

Blepharospasm is the technical name for eye twitching, something that may be nothing more than a nuisance but also quite disruptive. Occasional eye twitching does not require treatment other than stress reduction therapy. Unless the involuntary blinking or spasms of the eyelids are associated with Tourette’s syndrome or related neurological problems, which may require evaluation and treatment, the problem is not typically cause for concern. Otherwise, twitching caused by anxiety or rest may relieve fatigue. Blepharospasm is likely caused by abnormal function of the basal ganglion, which is the part of the brain responsible for controlling the eyelids’ muscles. If so, an injection of botox into the muscles is a considered treatment before undergoing myomectomy, the surgical removal of some of the muscles and nerves of the eyelids.

How The Brain Sees

Eye On Your Health

If you think about it, the eyes may be tasked with collecting imagery from the world around us. However, it is the brain’s job to make sense of the information collected by the eyes and enable us to see. Further, researchers wanted to know whether there is an area of the brain that is actually responsible for reading. Using functional MRI (fMRI) brain scans, it was found that people reading Braille activate the exact same part of the brain as sighted people use. This finding upends the conventional theory that the brain is divided into specialized regions which process the information they receive via one sense or another. According to this research, the brain is not so much a “sensory” machine as it is a “task” machine that can perform a function regardless of where the sensory input comes from.

More Than Mismatched Socks

Eye On Your Health

Color blindness may seem like a relatively innocuous malady, but it does pose some problems. Color blindness is generally passed from generation to generation and is more prevalent in men. People with color vision problems may find it difficult to distinguish between red and green stoplights and so have to concentrate more attentitively on their driving. Most color vision problems are inherited which means that the color sensing cone cells in the retina are not functioning properly, in which case there is no effective treatment other than wearing color enhancing lenses. But when color blindness is caused by cataracts, glaucoma, macular degeneration or diabetic retinopathy, addressing the underlying condition may help ease the symptoms.

Unsightly Bulges

Eye On Your Health

Keratoconus causes progressive thinning of the cornea, the transparent outer covering at the front of the eye. This leads to the development of a cone-like bulge, adversely altering vision. This condition occurs in about one in every 2,000 individuals, usually first diagnosed in patients in their late teens or early twenties. Initial symptoms usually include slight blurring and increased photosensitivity. Keratoconus may progress for a decade or two and then stabilize. Soft contact lenses may be used early on to correct mild nearsightedness and astigmatism, followed by rigid gas permeable (rgp) contacts if the cornea continues to thin and change shape. In severe cases, a corneal transplant may be required. A new treatment called corneal collagen cross linking may help strengthen the corneas of keratoconus patients. It involves a single application of riboflavin eye drops activated with low dose ultraviolet light for about a half hour.

When Parents See Red

Eye On Your Health

Conjunctivitis, or ‘’Pink Eye’’ as it is commonly known, is a common infectious eye disease among children at school or day care. The first symptom of conjunctivitis is eye discomfort followed by redness. The natural urge to rub the eyes can cause further inflammation of the conjunctive, the thin transparent membrane lining the inner surfaces of the eyelids, which fold back to cover the front surface of the eyeball. Also, discharges from the eyes during conjunctivitis cause crusts over the eyes. Treatment varies according to type. Bacterial conjunctivitis responds to prescription antibiotic drops or ointment, while viral conjunctivitis will disappear on its own. Both can be soothed with warm compresses to closed eyes.

Hardly Cause For Celebration

Eye On Your Health

Popped champagne corks can travel at speeds of 50 miles per hour. These traveling missiles can cause serious eye injuries and sometimes loss of vision when they hit the eye after exploding from bottles of sparkling wines. Being aware of this, every precaution should be taken when opening a bottle of the bubbly. First, never shake a bottle of the sparkly. To properly open a bottle, place a towel over the bottle to cover the cork, then firmly grasp the cork. Next, with the bottle pointed at a 45 degree angle and away from everyone, twist the cork slowly until it leaves the bottle, unable to fly because of the towel covering. In this way, a champagne celebration can be just that, and not a trip to the emergency room. Eye injuries associated with incorrect popping of champagne corks can and do lead to potentially devastating consequences, such as detached retina, scarring of the cornea, and acute glaucoma.

Talking Dirt

Eye On Your Health

Parents always tell their children to stop eating dirt for all the obvious reasons, and some legitimate not so obvious reasons. An internet survey of nearly 600 ophthalmologists revealed that 68 patients were affected by a parasite disease known as ‘’ocular toxocariasis’’ (OT) during a recent one year period. OT, which can occur when a person ingests dirt contaminated with microscopic toxocara eggs (which can come from the feces of an infected dog or cat), can lead to permanent vision loss. As a preventive measure, pet owners are urged to have their dogs and cats dewormed, properly dispose of pet waste, and restrict children’s play to clean, safe areas.

A Cataract Is Not A Tomato

Eye On Your Health

Ophthalmologists are often asked if a cataract must be “ripe” before surgery is elected. This notion stems from the fact that patients used to wait for their cataracts to harden, or “ripen” before they could have surgery. In those days, as various proteins in the normally flexible eye lens clumped together, and as the lens got stiffer, it was easier to remove a fairly intact lens through a relatively large incision. The best results were attained by extracting a solid lens that did not fall apart as it was lifted out. Today, lens “ripeness” is irrelevant as modern surgical procedure entails breaking up and suctioning out the clouded lens utilizing the “phacoemulsification” technique that requires a minuscule incision. There is no objective test to determine the need for cataract surgery. Patients must decide for themselves on the basis of their vision loss.

Clouded Thinking

Eye On Your Health

It would seem apparent that seniors would know of an eye condition which is a leading cause of blindness in their contemporaries. Yet, when older individuals express their knowledge of cataracts, misinformation abounds. An unfortunate aspect of this lack of knowledge of cataracts results in preventing those who need treatment from getting it by unrealistic expectations of treatment. Simply put, the U. S. National Eye Institute states that cataracts occur when the eye lens grow cloudy. Cataracts do not grow on top the eye. Nor should you wait until the eye lens becomes completely white before seeking surgical treatment. Cataracts can be removed and replaced with a clear, man-made lens with cataract surgery. With a 95% success rate, the surgery is generally performed under light sedation as an outpatient where the patient returns home the same day.
