    The use of optical coherence tomography angiography and optical coherence tomography to predict visual acuity in diabetic retinopathy

    Introduction Diabetic macular ischaemia (DMI) is associated with reduced visual acuity. Limitations exist in assessing the ischaemic component of diabetic retinopathy. Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique to distinguish retinal capillary layers and allow microvascular assessment. Evaluation of DMI is of prognostic significance when planning treatment regimens for diabetic maculopathy. The aims of this study were to evaluate OCTA to assess DMI and correlate findings with structural optical coherence tomography (OCT) features to predict visual acuity. Methods Cross sectional study of fifty-seven eyes ( n  = 57) of thirty-seven subjects with diabetic retinopathy. 26/57 (46%) eyes had ...
