Hello. I am 49 years old. I had a retina surgery on my left eye about 4 years back followed by a cataract surgery on the same eye within a gap of 6 months . My mother also had done the same surgery but at the age of 70 unlike me.i have always stayed n a routine checkup thrice a year. This time after having a close look in my eyes my doctor said that CDR is 0.3 for my right eye and 0.4 for my left eye. He said that this is the onset of glaucoma. I am very much worried please help me.
