My father, who is 76 years old, has been diabetic for the last 25 years. He takes medicine and controls it within the range throughout. Around 20 years back, he had a cataract operation in both the eyes. There is no IOL. His eye problem started before two years. Due to which, there is blurred vision. In the left eye, he has some vision, but in the right eye, the vision is very poor. According to the physicians, there is a cyst on the retina and for which they advise to inject Accentrix or Avastin. I am sending his FFA and OCT report. Kindly give your expert advice on the treatment and in which eye it is needed earlier. Among the two medicines, which is more suitable for my father?
