Hi Buster!
Mommaduck makes some very good points about the night blindness and its effect on daily life (it sucks).
Its a year round thing like RP; until you have it;its hard to comprehend its limitations.
A normal person dark adapts in a max of 20 mins in a fixed environment (room)
an RP sufferer can take over 2 hours to adapt if at all!
Your relative also has a learning disability as well which could also effect his cognitive ability ?
(Cognitive impairment encompasses orientation (understanding of where, what and who the person is), attention, concentration and memory)
Also remember RP's effects vary throughout the day for example on a familiar route(also don't forget the severe restriction of visual field) :
Walk into the direction of the sun;extreme glare sensitivity; white out!
Turn left walk parallel to it down a road and after a time some perception returns;enter the shade of buildings;back in the dark/nothing! from that back in the bright light;white out.
Most RP's need controlled lighting environments to function.
He will also have no depth perception trying to follow a familiar route is not easy.

Buster does your relative use an orientation aid such as a guide cane or long cane as this would satisfy the help they need to follow a familiar route. Can they see to or does he need help to cross a road can he cooe with changes/obsticles.

Many thanks Matchseller for your detailed advice. I'll bear all this in mind until its time to next do wall to wall PIP - likely to be sometime in the not too distant future. For now, after recent form-filling - talk about burning the midnight candle - I need to put PIP to the back of my mind to avoid going mad.
