| Abstract;Purpose: Glaucoma screening by fundus photography is highly valued; its accuracy is also economically important. We investigated the screening accuracy of physician, ophthalmic residents, and glaucoma specialists, and examined the efficiency of screening training for ophthalmic residents. Methods: We selected 20 eyes of patients who consulted an ophthalmologist at our hospital after being diagnosed with possible glaucomatous cupping on health check. Of the 20 eyes, 11 were normal, 6 had normal-tension glaucoma, and 3 had primary openangle glaucoma. Digital slides were prepared from the fundus photographs of these eyes. In method 1, a physician, second-year ophthalmic residents, ophthalmologists, and glaucoma specialists judged glaucomatous changes after fundus photographs were presented on a CRT (cathode ray tube) monitor for a maximum of 20 seconds. In method 2, the same experiment was repeated with 10 first-year ophthalmic residents fur different times, at periods of 3, 4, 6 and 7 months. The 4- and 7-month experiments were performed immediately after the residents had received a lecture from a glaucoma specialist on detecting optic disc cupping. None of the judges were offered correct answers. Results: The sensitivity of the physician was 83.3% and was the highest. However, specificity was significantly higher in glaucoma specialists, ophthalmologists, and second-year residents, in descending order, compared to the physician. The sensitivity of the first-year residents was 67.8%, 91.1%, 74.4%, and 95.6%, and the specificity values were 52.7%, 57.3%, 73.6%, and 91.8% at 3, 4, 6, and 7 months, respectively. Sensitivity increased just after the first-year residents received the glaucoma detection lecture; however, specificity increased as their clinical experience increased. Numerous experiences observing normal eyes seemed to improve specificity. Ultimately, the accuracy of detection approximated that of the glaucoma specialists.... (author abst.) |
