The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500-7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 20–60 years old.

In the first day of the program he checked two patients, patient A and patient B. The test result showed that patient A had Retinitis, but patient B did not have Retinitis. Then next day 
David checked two other patients, patient C and patient D. Patient C was 40 years old, but patient D was 80 years old. He found both patient C and D had Retinitis.
Output (English): Will David find patient A is in risk of blindness or not in risk of blindness?
