A prospective study led by Dr. Paul Mitchell of the University of Sydney, Australia, suggests that retinal micro-artery stenosis predicts an increased risk of open-angle glaucoma 10 years later. However, because glaucoma takes a long time to develop, it is unclear whether small arterial stenosis is its cause or part of its progression. ophthalmology.2013.120(1):84-90. detection of arterial diameter in the retina by computer imaging tools would allow effective identification of the risk of open-angle glaucoma. Many patients develop the disease without realizing it and are not seen until they develop severe visual impairment. Early detection gives the opportunity for early intervention.”
