Answer

When laser photocoagulation is precluded in the presence of an opaque media, such as in cases of cataracts and vitreous hemorrhage, cryotherapy may be applied instead.

The principles behind the treatment are basically the same—that is, to ablate retinal tissue for oxygen demand to be decreased and to induce a chorioretinal adhesion, which could increase oxygen supply to the retina in the hope of preventing or down-regulating the vasoproliferative response.
