Ophthalmology News and Research

RSS

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Discovery has implications for research on restoring mobility to people who have lost motor functions due to spinal cord injury

Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain.

First-of-its-kind test on a microchip array will help diagnose retinitis pigmentosa

Rapid genetic testing for eye disease is becoming a reality, thanks to a technology developed at the University of Michigan Kellogg Eye Center.

Immune cells known as macrophages linked to growth of lymph vessels in eyes,

Scientists at Schepens Eye Research Institute have discovered that a particular immune cell contributes to the growth of new lymph vessels, which aid in healing. This cell, known as a macrophage, is called in by the body during the wound healing process.

Immunosuppressive drug mycophenolate mofetil may be effective in controlling inflammatory eye diseases

The immunosuppressive drug mycophenolate mofetil, used to prevent rejection of transplanted hearts, kidneys and livers, may also be effective in controlling inflammatory eye diseases, according to a study by Johns Hopkins' Wilmer Eye Institute.

First human gene mutation that causes extreme farsightedness

Working with an Amish-Mennonite family tree, Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness.

Researchers have discovered a gene linked to age-related maculopathy

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies.

Findings could lead to gene therapy cure for childhood blindness

In findings that could lead to curing some forms of congenital blindness through gene therapy, researchers at UCLA have discovered that RPE65, a gene missing in infants born with the blinding disease Leber congenital amaurosis, is also a key enzyme in the visual cycle. The identity of this enzyme has long been a mystery to scientists.

Cataracts a risk for pilots and astronauts

According to the results of a new study, airline pilots have a greater risk of developing cataracts because of exposure to cosmic rays while flying.

Airline pilots have an increased risk of nuclear cataracts

Airline pilots have an increased risk of nuclear cataracts [common type of cataract, associated with aging] compared with non-pilots, and that risk is associated with cumulative exposure to cosmic radiation, according to a study in the August issue of Archives of Ophthalmology.

New insight into age-related macular degeneration

Age-related macular degeneration is the leading cause of blindness in older adults, yet researchers are still in the dark about many of the factors that cause this incurable disease.

New compound ruboxistaurin may decrease vision loss in diabete

A multicenter international study chaired by a Joslin Diabetes Center investigator and reported in the July issue of the American Diabetes Association's journal Diabetes brings hopeful news to the 18 million people in the United States -- and millions more worldwide -- with type 1 or type 2 diabetes.

Nearly two million Americans are treated for eye injuries per year

Because eye injuries are rarely serious enough to require hospitalization, to understand the extent of eye injuries in the U.S., inpatient and outpatient facilities, in addition to other settings, must be considered, according to background information in the article.

Increasing stiffness of the aging eye may make older adults more susceptible to eye damage following trauma

Using a computer model of the eye, Stitzel and colleagues investigated possible injury mechanisms in the eyes of elderly individuals and the effects of lens stiffness on injury prediction by the model. The new data document that the risk of certain types of eye injury increases with age.

Children who were born prematurely are more likely to have eye problems

Eye and neurological problems are common in premature infants, according to background information in the article, but little is known about the effects of prematurity on visual acuity, the sharpness or clarity of vision.

Eyeballs substituted for a passkey or a fingerprint

With iris security identification recently in the news, the American Academy of Ophthalmology explained how an eyeball can be substituted for a passkey or a fingerprint.

New generation of lenses makes evolutionary leap in eliminating need for glasses

The need for reading glasses or bifocals as we age may begin fading from sight with the latest generation of intraocular lenses.

New approach to inhibiting blood vessel growth or angiogenesis

A manmade protein with a tail of amino acids delivered to target cells can dramatically reduce blood vessel growth that obstructs vision or feeds a tumor, researchers have found.

Allergies increase risk for corneal transplant rejection

Corneal transplant patients who suffer from eye allergies are at a significantly higher risk of transplant failure than those without allergies, UT Southwestern Medical Center researchers have shown.

22 May 2005

Common antibiotic called minocycline may slow or prevent diabetic retinopathy

The team found that minocycline, often used to treat acne, limits by about 50 percent the retinal damage caused by microglia. Microglia are cells that act as the "cleanup crew" for the Central Nervous System (CNS).

Green laser pointers can cause visible harm to the eye's retina

Mayo Clinic ophthalmologists have found commercially available Class 3A green laser pointers can cause visible harm to the eye's retina with exposures as short as 60 seconds. The findings will be published in the May issue of Archives of Ophthalmology.
