ROCHESTER, Minn. — The Mayo Clinic Board of Trustees recognized four new named professorships, the highest academic distinction for faculty members at Mayo Clinic, during its quarterly meeting today.
Michael Brodsky, M.D., a physician with joint appointments in the Department of Neurology and Department of Ophthalmology, is recognized as the Knights Templar Eye Foundation, Inc. Professor in Ophthalmology Research. The Knights Templar Eye Foundation, incorporated in 1956, is a charity sponsored by the Grand Encampment of Knights Templar. The organization’s mission is to improve vision through research and education and by supporting access to care.
As a researcher, Dr. Brodsky focuses on evolutionary mechanisms of infantile strabismus (a condition in which the eyes are not properly aligned with one another); congenital optic disc anomalies; ocular motor physiology; nystagmus (a condition of involuntary eye movement acquired in infancy or later in life, that may result in reduced or limited vision); and other ocular motility disturbances. He has authored or co-authored several textbooks, including the definitive Pediatric Neuro-Ophthalmology.
He has also established a video-oculography laboratory at Mayo Clinic to study the role of binocular luminance disparity in infantile strabismus.
Douglas Husmann, M.D., Department of Urology, is recognized as the Anson L. Clark Professor in Urology. This professorship was established in 1974 by The Clark Foundation of Dallas, Texas, in memory of Anson L. Clark, M.D. Dr. Clark was a member of the Mayo Clinic staff in the section of special urology and an instructor in urology from 1931 to 1934.
As a urologist, Dr. Husmann’s clinical and research focus includes pediatric and reconstructive urology, and he has extensive experience in urologic reconstructive surgical procedures in both congenital abnormalities and traumatic injuries. He excels at translating basic science findings to the clinical arena. His work has resulted in numerous advances in the fields of androgen receptor physiology, the management of reproductive congenital abnormalities, traumatic genitourinary injuries and reconstructive urology.
ESTIMADA MAYO CLINIC:
¿Cuál es la causa de los ojos secos? ¿Existe algún tratamiento eficaz, aparte de constantemente aplicar gotas en los ojos para mantenerlos húmedos?
La sequedad de los ojos ocurre cuando no hay suficiente producción de lágrimas o éstas son de mala calidad. El tratamiento de los ojos secos suele incluir medicamentos, colirios y ungüentos; pero cuando los tratamientos normales no surten efecto, las nuevas terapias para un cierto tipo de sequedad de los ojos pueden ofrecer alivio.
A fin de mantener clara la visión y sentir comodidad en los ojos, es necesario que una capa homogénea de lágrimas cubra la superficie del ojo. Esa película lagrimal tiene tres componentes básicos: un estrato lípido, un estrato acuoso y un estrato de mucina. La sequedad de los ojos aparece cuando se presenta un problema con cualquiera de ellos. [...]
Most people have heard that carrots are good for their eyes, but do you know that other foods help protect vision and prevent eye disease? The National Eye Institute and other vision experts note that a healthy diet is an important factor in eye health. Researchers have found that certain nutrients with antioxidant properties are beneficial. These include carotenoid compounds such as beta-carotene, lutein and zeaxanthin, and vitamins C and E. Zinc and omega-3 fatty acids are also important for eye health.
Mayo Clinic eye and nutrition experts offer the following lists to help you choose foods for better eye health:

DEAR MAYO CLINIC: My grandson had a virus with flu symptoms. Then one of his eyes got very red, but it wasn’t itchy or mattered shut. When my daughter took him to the doctor, she was told it was the virus settling in his eye. But it wasn’t pink eye. What’s the difference between this type of eye infection and pink eye? Are the treatments different?
ANSWER: The two conditions you mention are both eye infections,
and they are actually also both forms of
pink eye. The difference is that the type of infection your grandson had is caused by a virus. The other is caused by bacteria. Viral eye infections typically do not require any treatment. Bacterial eye infections are usually treated with antibiotic eye drops.
Eye infections are common, especially in children. As in your grandson’s case, they often happen when a child has a cold. Both viral eye infections and bacterial eye infections are called conjunctivitis, or pink eye.
ANSWER: Dry eyes happen when your eyes do not make enough tears or when those tears are poor quality. Treatment of dry eyes often includes medication, eye drops or ointment. But new treatments for a certain type of dry eyes may provide relief when standard treatments fail.
To keep your vision clear and your eyes comfortable, you need a smooth layer of tears consistently covering the surface of your eyes. The tear film has three basic components: oil, water and mucus. Problems with any of these can cause dry eyes.
Symptoms of dry eyes often include blurry vision, eye redness, sensitivity to light, and a burning, gritty or scratchy feeling in your eyes. Dry eyes may cause excessive tearing in some cases. They can make it difficult to wear contact lenses, too. Medications, age, eyelid problems, environmental factors (such as climate) and excessive eye strain can all result in dry eyes.
For some people with chronic dry eyes, the problem stems from glands in the eyelids, called the meibomian glands. Normally, these glands make oil that slows the evaporation of tears. If the glands become blocked, tears do not contain enough oil. Then the tears evaporate too quickly, and eyes become dry. This type of dry eye condition is known as evaporative dry eye. Inflammation of the eyelid skin — a disorder called ocular rosacea — can often result in blocked meibomian glands. [...]
DEAR MAYO CLINIC: My 11-year-old began wearing glasses for nearsightedness when he was 7. Since then his prescription has gotten steadily worse. He has needed new glasses about every eight to ten months. His optometrist says this is not uncommon. But I’m worried. Is there an age a child’s eyesight typically stops changing? Should we take our son to see an ophthalmologist for a more thorough assessment?
ANSWER: From your description, your son’s changing eyesight sounds like it is within the normal range for a child his age. Unless he has other symptoms or other health problems that could be affecting his eyesight, it is unlikely that he needs a consultation with an ophthalmologist at this time.
Nearsightedness, or myopia, is a vision condition in which you can see objects that are near to you clearly, but objects farther away are blurry. Nearsightedness happens either when the cornea — the clear front surface of your eye — is curved too much or when your eye is longer than normal. That causes light coming into your eye to be focused in front of the retina at the back of your eye, instead of directly on the retina. The result is blurry vision.
Many children develop nearsightedness during the early elementary school years, often around age 6 or 7. The condition usually continues to get worse throughout the teen years as a child grows. An increase in nearsightedness often is most rapid during early adolescence, around ages 11 to 13 years. It tends to slow and then stabilize by the late teens or early 20s. [...]
Poison ivy grows as vines or low shrubs in most climates. Each leaf on a poison ivy plant has three smaller leaflets. Contact with any part of the poison ivy plant can cause red, swollen skin; blisters; and severe itching, sometimes within hours after exposure.
A poison ivy rash usually resolves on its own within a few weeks. In the meantime, control itching with an over-the-counter anti-itch cream, such as calamine lotion or hydrocortisone cream. An oatmeal bath and cool compress also might be helpful. Consult your doctor if you have a severe poison ivy rash or if the rash involves your eyes, face or genital area. Poison oak and poison sumac cause a similar rash.

PHOENIX — In a new Mayo Clinic study, researchers examined the physical act of reading to see if practicing eye movements in school could lead to better early reading fluency.
Saccades or rapid eye movements are required for the physical act of reading. Previous studies have shown that the ability to perform complex tasks such as saccadic eye movements are not fully developed at the age when children begin to learn to read. Eye movements in younger children are imprecise, resulting in the need for the eyes to go back to re-read text, leading to slower performance. When translated into the task of reading, it slows the reading rate and leads to poor reading fluency and may affect reading comprehension and academic performance. [...]
