Role of OCT-A in High Volume Clinics

Does OCT-A have a place in high-volume clinics? In this interview from ASRS 2016, Dr. Catherine Egan discusses her experience using OCT Angiography to monitor patients with diabetic retinopathy at Moorfields Eye Hospital. OCT-A may indicate areas of capillary non-perfusion in the macula or mid-peripheral areas that may not be detected by fundus photography, a symptom that was shown in the RISE and RIDE studies to greatly increase the risk of proliferation even with regular anti-VEGF therapy. As the imaging also provides OCT data, it can determine if a change in disease management is necessary due to new vessels breaching the internal limiting membrane. Dr. Egan uses OCT-A for patients who are unable to have a fluorescein angiogram due to allergies, pregnancy, time constraint or to help convince a hesitant patient to agree to a FA.
