Fig. 2From: Multifactor analysis of delayed absorption of subretinal fluid after scleral buckling surgeryMeasurement of choriocapillaris flow density Using the OPTOVUE HD Angio Retina mode the blood flow area was measured in the circular range of 1.50 mm radius of the choriocapillaris layer. CCFD was determined by dividing the blood flow area by the selected areaBack to article page
