Some health issues are not so plain to see:
1. Arterial plaques. Atherosclerosis is the disease process that causes cholesterol plaques to form in arteries, including the carotid arteries in the neck and the coronary arteries. Bits of cholesterol (usually from the carotids) can break away from these plaques and travel via the bloodstream to the eye, where they lodge in small arteries in the retina, the delicate network of blood vessels and nerve cells at the back of the eye. Kastl explains that these minute yellowish blockages, known as Hollenhorst plaques, can be evidence of severe atherosclerosis. Ultrasound testing of the carotid arteries may be needed to pinpoint the plaque or plaques.
2. Optic nerve abnormalities. The optic nerve, which transmits visual information from the retina to the brain, is visible at the rear of the eye. It’s supposed to be pink. A pale optic nerve can be an early manifestation of MS, as well as evidence of a brain tumor or aneurysm, Williams says.
Retinal defects. Various medical conditions, notably diabetes and high blood pressure, can damage the blood vessels and nerves in the retina (as well as elsewhere in the body). This retinal damage — which can cause blindness — can take several forms, including tiny hemorrhages, leaks of yellowish fluid, and puffy-looking whitish patches known as cotton wool spots, Iwach says. White patches on the retina can also be a manifestation of cytomegalovirus infection — possibly a sign of AIDS. In some cases, the retina is overgrown with tangled and highly fragile blood vessels — the result of a process known as neovascularization.
If you notice one of the signs listed above in your own eyes, alert your doctor. We look at the physical findings and then listen to the patient’s story line and family history. Then we decide what testing is necessary. The last thing you want to do is ignore one of these signs — especially one that has shown up recently.

Some ocular manifestations of systemic disease can be seen only by a trained specialist during the course of an eye exam. Others are plain for all to see. Here are 8 of the most common eye signs and what they might be saying about your health:
1. Bloody eye. The eye’s transparent outer layer, called the conjunctiva, is nourished by numerous tiny blood vessels. If these burst, blood may pool on the white of the eye (sclera). A subconjunctival hemorrhage, as it is known among doctors, can be caused by a blow to the eye but in most cases has no obvious cause. In rare instances, a subconjunctival hemorrhage can be a sign of severe high blood pressure or a platelet disorder, which can interfere with clotting.
2. Bulging eyes. Though prominent eyes may simply be a family trait, eyes that appear to bulge may be evidence of thyroid disease. Abnormal levels of thyroid hormone cause tissues surrounding the eye to swell, making it appear that the eye is bulging.
3. Different colored eyes. Also called heterochromia iridis, this condition is usually inherited. A change in color may be due to bleeding, a foreign body in the eye, glaucoma, inflammation in the eye or other conditions such as Waardenburg syndrome or neurofibromatosis.
4. Droopy eyelid. This condition, known among doctors as ptosis, can be simply a sign of aging. But in rare cases it is evidence of a brain tumor or a neuromuscular disease known as myasthenia gravis (MG). MG is an autoimmune disorder that weakens muscles throughout the body.
5. Pupil abnormalities. The pupils of healthy people are usually (but not always) symmetrical. They’re usually of the same size, and they usually show the same reaction upon exposure to light. If one pupil is bigger than the other, or if one pupil shrinks less, or more slowly, on exposure to light, there could be an underlying medical problem. Possibilities include stroke, brain or optic nerve tumor, brain aneurysm, syphilis, and multiple sclerosis (MS). Finally, many medications — including illicit drugs — can cause the pupils to appear unusually small or large, says Peter Kastl, MD, PhD, professor of ophthalmology, Tulane University School of Medicine.
6. Rings on the cornea. A rare hereditary disorder known as Wilson’s disease can cause copper to accumulate in various tissues, including those in the brain and liver. Copper deposits sometimes form on the inner surface of the cornea (though they appear to a casual observer to be on the iris, the colored disk that surrounds the pupil). These “Kayser-Fleischer rings” are themselves harmless. But without appropriate treatment, Wilson’s disease can be fatal.
7. Thickened eyelid. In very rare cases, a thickening or deformation of the eyelid is a sign of neurofibromatosis, a rare hereditary disorder marked by the growth of tumors along nerve fibers (the tumors themselves are called plexiform neurofibromas). Joseph Merrick, the 19th Century Englishman known as the Elephant Man, was long thought to have had neurofibromatosis. Experts now believe that he suffered from another rare condition known as Proteus Syndrome.
8. Yellow eyes. Diseases of the liver, including hepatitis and cirrhosis, can turn the scleras yellow. The color is caused by the buildup of bilirubin, a compound created by the breakdown of hemoglobin, the oxygen-carrying molecule inside red blood cells. The medical term for yellow eyes is scleral icterus — even though it’s not actually the scleras that turn yellow, but the conjunctiva.




Are the eyes “windows to the soul,” as the ancient proverb has it? Maybe, but they are certainly portals through which one can glimpse signs of certain health problems — not only eye disorders like cataracts and glaucoma, but also systemic illnesses like diabetes mellitus and cardiovascular disease. Sometimes the signs of these diseases are visible in, on, or around the eyes long before symptoms appear.

“The eyes truly are unique real estate,” says Andrew Iwach, MD, associate clinical professor of ophthalmology at the University of California San Francisco and executive director of the Glaucoma Center of San Francisco. “They’re the only place in the body where you can see a bare nerve, a bare artery, and a bare vein without doing any cutting. And the disease processes we see occurring in the eye are probably occurring in the rest of the body.”

The list of systemic diseases that can have ocular manifestations is a long one; in addition to diabetes and cardiovascular disease, it includes aneurysms, HIV, cancer, and rare hereditary diseases. The list is one reason eye experts recommend periodic eye exams.

“Everyone should have a comprehensive eye exam by age 40,” says Ruth D. Williams, MD, an ophthalmologist and glaucoma specialist in Wheaton, Ill., and, like Iwach, a spokesperson for the American Academy of Ophthalmology. “People who have a family history of eye problems should be seen earlier, and anyone who is having eye trouble should see a doctor right away. But people shouldn’t wait until they experience symptoms to see a doctor, because many eye problems are silent,” meaning they cause no symptoms.

Dry eye symptoms may include any of the following:

-stinging or burning of the eye;
-a sandy or gritty feeling as if something is in the eye;
-episodes of excess tears following very dry eye periods;
-a stringy discharge from the eye;
-pain and redness of the eye;
-episodes of blurred vision;
-heavy eyelids;
-inability to cry when emotionally stressed;
-uncomfortable contact lenses;
-decreased tolerance of reading, working on the computer, or any activity that requires sustained visual attention;
-eye fatigue.
NOTE: If symptoms of dry eye persist, contact Dr. Landrio to get an accurate diagnosis of the condition and begin treatment to avoid permanent damage.




A drooping eyelid can stay constant, worsen over time (progressive), or come and go (intermittent). It can be one-sided or on both sides. When drooping is one-sided (unilateral), it is easy to detect by comparing the two eyelids. Drooping is more difficult to detect when it occurs on both sides, or if there is only a slight problem.

A furrowed forehead or a chin-up head position may indicate that someone is trying to see under their drooping lids. Eyelid drooping can make someone appear sleepy or tired.

Drooping lids are either present at birth (congenital) or develop later in life. A drooping eyelid is not a reason to panic, but you should report it to your doctor.

Causes can include:
Drooping eyelids may be due to a variety of conditions include aging, diabetes, stroke, Horner syndrome, myasthenia gravis, or a brain tumor or other cancer that affects nerve or muscle reactions. Below are some common causes.

Both eyelids drooping:
Medical problem, such as myasthenia gravis
Migraine headaches
Normal aging process
Normal variation of the eyelids

One eyelid drooping:
Growth in the eyelid, such as a stye
Medical problem
Nerve injury
Normal aging process
Normal variation

Contact Dr. Landrio if:

1. Eyelid drooping is affecting your appearance or vision
2. One eyelid suddenly droops or closes
3. It is associated with other symptoms, such as double vision

-Men are more likely to sustain an eye injury than women.

-Most people believe that eye injuries are most common on the job — especially in the course of work at factories and construction sites. But, in fact, nearly half (44.7 percent) of all eye injuries occurred in the home, as reported during the fifth-annual Eye Injury Snapshot (conducted by the American Academy of Ophthalmology and the American Society of Ocular Trauma).

-More than 40 percent of eye injuries reported in the Eye Injury Snapshot were caused by projects and activities such as home repairs, yard work, cleaning and cooking. More than a third (34.2 percent) of injuries in the home occurred in living areas such as the kitchen, bedroom, bathroom, living or family room.

-More than 40 percent of eye injuries every year are related to sports or recreational activities.

-Eyes can be damaged by sun exposure, not just chemicals, dust or objects.

-Among all eye injuries reported in the Eye Injury Snapshot, more than 78 percent of people were not wearing eyewear at the time of injury. Of those reported to be wearing eyewear of some sort at the time of injury (including glasses or contact lenses), only 5.3 percent were wearing safety or sports glasses.
