Diabetics can have leakage at the macular, the central part of one’s eyesight, which usually presents with blurred vision. The ophthalmologist can detect this clinically, by using an optical coherence tomography (OCT) scan of the macular. If the leakage is too close to the central vision, laser is not suitable and the ophthalmologist may suggest an injection of anti-VEGF (protein inhibitors like Avastin or Lucentis for vascular endothelial growth factor) or cortisone into the eye.
