Early Predictor for Glaucoma

A new study finds that certain changes in blood vessels in the retina can be an early warning that a person is at increased risk for glaucoma. Using diagnostic photos and other data from the Australian Blue Mountains Eye Study, the researchers showed that patients who had abnormally narrow retinal arteries when the study began were also those who were most likely to have glaucoma at its 10-year endpoint. If confirmed by future research, this finding could give ophthalmologists a new way to identify and treat those who are most vulnerable to vision loss from glaucoma.
