Clinical imaging tools have become an integral part of ophthalmic practice, serving to identify, document and monitor pathology as well as provide useful aids for patient counselling. Of the growing suite of imaging modalities at the disposal of clinicians, retinal photography, optical coherence tomography (OCT), fluorescein fundus angiography (FFA) and B‐scan ultrasonography are central to the management of patients with diabetic retinopathy. A number of clinical studies, chiefly case series, have demonstrated substantial agreement between non‐mydriatic UWF imaging and both mydriatic clinical biomicroscopy and seven‐field stereophotography for diabetic retinopathy severity grading. Ultrasonography plays an important role in the assessment of diabetic retinopathy when opacification of the ocular media precludes a satisfactory view of the retina. FFA has been an important diagnostic technique for diabetic retinopathy since its advent in 1959. Furthermore, diabetic macular ischaemia demonstrated on fluorescein angiography has been linked with the disruption of photoreceptors on OCT.
