is because of defective function or diseases affecting the retinal cells which are responsible for night vision called as rods. Six toes and fingers along with the night blindness is seen together in some syndromes like Moon biedel syndrome
, where the affected patient will have retinitis pigmentosa
and polydactyly or six fingers and toes.
Unfortunately there is no cure for this syndrome, but definitely progression of vision loss
can be delayed by treatment depending on the severity of involvement.
Hence I advice you to consult your eye doctor preferably retina specilaist for examination and opinion depending on the severity of the disease.
