I think this would depend entirely on how the sensory impairment came about, since most genetic problems are not isolated, but carry a bunch of other related problems (all of which can impact intelligence).
Lose your eye sight in an accident? I would grant there is likely no difference on average.
Otherwise, the null hypothesis is that intelligence (and a whole host of other problems) are likely worse, on average.
