    4. Optical coherence tomography angiography of foveal neovascularisation in proliferative diabetic retinopathy

      Optical coherence tomography angiography of foveal neovascularisation in proliferative diabetic retinopathy
      A 52-year-old man, a known case of type 2 diabetes mellitus and hypertension, who presented to us with bilateral diminution of vision since 1year. He was diagnosed as a case of bilateral proliferative diabetic retinopathy and hypertensive retinopathy. A non-invasive imaging modality, optical coherence tomography angiography (OCTA), detected foveal neovascularisation in a background of diffuse diabetic macular oedema which would have been obscured by other investigations like fluorescein angiography.
