Common Eye Condition Linked to Elevated Eye Pressure
Posted 10 Nov 2010 by Drugs.com
WEDNESDAY, Nov. 10 – A eye condition called corneal arcus may be associated with elevated eye pressure, which in turn is a risk factor for glaucoma, a new study suggests. It also found that corneal arcus – in which a ring of fats accumulates around the cornea – appears to be common in middle-aged and older adults. Corneal arcus may be associated with cardiovascular disease. Researchers examined the eyes of 3,015 people, aged 40 to 80, and found that corneal arcus was present in the right eyes of 57.9 percent of them. After adjusting for a number of factors, the researchers found that eyes with corneal arcus tended to have higher intraocular (inside the eye) pressure, thicker corneas and altered corneal curvatures. "There is no known explanation for the association of corneal arcus with higher intraocular pressure," wrote Dr. Renyi Wu, of the Singapore Eye Research Institute, and ... Read more

Relieving Eye Pressure May Slow Glaucoma
Posted 9 Aug 2010 by Drugs.com
MONDAY, Aug. 9 – Patients with glaucoma who have more rapid visual field change than other patients may benefit from a reduction of pressure within the eyeball, new research suggests. In the study, 216 patients with open-angle glaucoma were given standard treatment for controlling intraocular pressure (a targeted reduction of 30 percent or more) and were followed up with re-examination every four months. Patients whose glaucoma continued to progress received treatment to achieve an additional 20 percent or more reduction in intraocular pressure. Being older and having abnormal levels of anticardiolipin antibody (which is an antibody directed against a certain protein in the body) were associated with a more rapid rate of visual change. But reducing intraocular pressure appeared to slow the rate at which some of these patients experienced declines in visual field, the study authors ... Read more
