00:10
So what could be changes observed in their retina? so there are several retinal disease which observed in case of age people.

So this is mainly due to the aging.
00:28
As the age is increased, there is gradual reduction.
00:35
So by increasing their age, gradual reduction in pupil size.
00:44
So the pupil is the one which help into the entering the light of into the eyes.
00:51
So the less light entered into the eyes.
00:56
So these go to the retina and we know the retina has this cell which is the rod and cold.

Cell.
01:04
So in case of aged people there is a decrease number in rod cell.
01:11
