Rahul was only six-months-old when his family realised that his eyes didn’t respond to visual stimuli the same way as compared to other kids his age. For almost four years, they ran from pillar to post and got numerous tests done with no success. While some doctors deemed it as a passing phase, others failed to diagnose what his condition was all about.
It was only in 1998 when a four-year-old Rahul was taken to Chennai-based Shankar Netralaya, was he diagnosed with a congenital retinal condition that he had been affecting his vision from birth.
