The 300 consecutive patients over a 7-month observation period in 2018 were assessed in VCs by both OPs and medical retina consultants. The degree of agreement in treatment decisions between doctors and photographers, as well as adverse events, was recorded. The change in number of patients seen in VCs over two years was also measured.RESULTS: There was 100% agreement in management decisions between doctors and photographers during the 300-patient observation period. No adverse events were recorded. In 2017, 572 patients were seen in VCs by doctors. After OP clinics were introduced in 2018, this number increased by 24% to 709 patients seen by both photographers and doctors. There was a significant increase in mean number of patients seen per month between 2017(47.7±11.7) and 2018(59.1±14.4;P=0.045, 95%CI-22.5 to-0.296).CONCLUSION: OPs can manage certain medical retina patients in VCs appropriately and can increase clinic capacity significantly for particular conditions.展开更多
