The iris does not become transparent, but there I sloss of the pigment on
the back of the iris. However, that is not the major reason for the vision
problems.
There is lack of pigment under the retina. In addition, most cases have
macular hypoplasia; poor development of the macula - the region of the
retina responsible for sharp vision and color vision. This usually limits
vision to about 20/200 or so. This poor vision causes loss of the vision
"lock", allowing nystagmus to occur. Many are hyperopic, and benefit from
eyeglass correction, particularly with a tint (brownish-red is usually
preferred) to hep reduce the light overload.
