slight detachment of retina results in a decrease in lenght from the optic center and the subject exhibits
a. near sightedness(ans)
b.far sightedness
c.strabismus
d.nystagmus

since there is decrease in the length between the optic center and retina, the image will be formed behind the retina, so this is a clear case of far sightedness.
