Uranus's and Neptune's Moons

When Voyager passed Uranus and Neptune back in the early 80's, did it get
close enough to their moons to see whether there were any tantalizing signs
of ice, or is it still unknown whether we have a complete catalog of all
the icy moons of the gas giants?

Yes, it did get close enough to image a number of these moons and determine
their size as well as resolve some surface detail. From their relatively low
density (most less than 2g/cc), at least a portion of their compositon appears
to be water ice. Our "catalog" may not be entirely complete, as a few more
moons have been discovered since the Voyager flyby. Clear skies to you.
