Two-field retinal photography, a screening tool for detecting diabetes-related retinopathy, might provide a useful alternative to routine exams by eye doctors for people with diabetes, say researchers in the Netherlands, writing in the December 2001 issue of Diabetes Care.
Lead researcher Catharina Stellingwerf, MD, of the University Hospital of Groningen told Diabetes Health that two-field retinal photography involves photographing the retina—which is susceptible to vascular problems in people with diabetes-using a camera on a slitlamp.
“Two pictures are taken of each eye: one of the central retina and one of the retina next to the optic nerve,” says Stellingwerf. The procedure can be performed by a primary care doctor, and the pictures are then sent to an ophthalmologist, who can check for any signs of vascular damage caused by diabetes.
