'Fluorescent' Retinal Cells Warn of Eye Disease

re equal to and often superior to the standard tests.

The researchers also found that FA data more accurately described the degree of disease in each patient's eye as compared to the standard vision tests. The patients with PTC had FA values that averaged 60 percent greater in the eye that was more severely affected, the study said. By contrast, an age-matched control group had no significant difference in FA values between their healthy eyes.

"Early treatment for eye disease is so important, and this study suggests that FA activity is a very good indicator of eye disease," Elner, an ophthalmologist and a pathologist, said in a prepared statement. "Cardiologists have long used blood pressure testing to head off heart disease. We believe that FA testing will likewise be a helpful diagnostic tool for eye doctors looking to prevent blindness."

Elner and Petty have patented the device and are investigating its use as a screening device in diabetes and major eye diseases.
