Imaging in diabetic retinopathy

Abstract

Imaging in diabetic retinopathy (DR) has developed over the years and the advantages are multifold. Various imaging modalities are currently available, which is of great diagnostic and prognostic value in the management of DR. Optical coherence tomography (OCT) has revolutionized the management of diabetic maculopathy. OCT has now become indispensable for initiating and assessing diabetic macular oedema (DMO) while on treatment with intravitreal injections. Recent introduction of optical coherence tomography angiography (OCTA) has significantly reduced the need for fundus fluorescein angiography (FFA) for macular ischaemia and proliferative retinopathy. Ultra-wide field (UWF) imaging modalities for colour fundus and UWF FFA are very useful to document and assess overall retinal state highlighting the periphery. Bscan ultrasonography of the fundus is an useful tool to assess retinal status in proliferative DR with vitreous haemorrhage.

“…These images capture essential structures within the eye, including blood vessels, the optic disc, and the macula. The information derived from these structures in retinal images is instrumental in diagnosing and treating a range of retinal conditions [3] , [4] , [5] .…”
