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.

Reparative cells offers new avenue for fighting multiple sclerosis

Plaques that form around the nerve cells of people with multiple sclerosis are apparently what disable people with the disease. But partly developed reparative cells within the plaques provide hope for a treatment, a UT Southwestern physician reports in the New England Journal of Medicine.

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.
