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.

Study finds light sensing cells develop before vision

Investigators at Washington University School of Medicine in St. Louis have found that cells making up a non-visual system in the eye are in place and functioning long before the rods and cones that process light into vision.

Fee-for-service associated with a significantly higher rate of cataract surgery

A system in which physicians are reimbursed for each procedure they perform (fee-for-service) is associated with a significantly higher rate of cataract surgery and related surgical costs, compared to a system in which physicians receive a lump sum for each patient they manage (contact capitation), according to a study in the December issue of Archives of Ophthalmology.

Retinal imaging technology helps heart

Routine visits to an Optometrist may soon provide us with diagnosis of vision complications and screening for cardiovascular disease.

Study of 30-day extended wear contact lenses

A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive 24-hour periods.

Recognizing facial expressions is separate from identifying familiar faces in autism or Asperger's

In contrast to previous reports, for those with autism or Asperger's syndrome, recognizing facial expressions is separate from identifying familiar faces, according to a study published in Neurology, the scientific journal of the American Academy of Neurology.

Chlamydia pneumoniae may cause vision problems

Researchers at the Massachusetts Eye and Ear Infirmary (MEEI) have found that Chlamydia pneumoniae, a bacterium linked to heart disease and capable of causing chronic inflammation, was present in the diseased eye tissue of five out of nine people with neovascular, or "wet," age-related macular degeneration (AMD).

Fndings shed some light on the brain mechanisms involved in schizophrenia

Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers.

Treating malignant melanoma of the uvea with radiation therapy can spare patients from significant vision loss

Treating a rare form of eye cancer with radiation therapy can spare patients from significant vision loss, according to new research at Wake Forest University Baptist Medical Center.

New glaucoma risk calculator

High eye pressure is the leading risk factor for glaucoma, and is the only modifiable one. If glaucoma is untreated, vision loss may continue, leading to blindness in some individuals.

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.

11 Aug 2005

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.
