In this study, the authors induced vitreous hemorrhages in both eyes of rabbits. Daily echographic control was carried out and when the formation of endovitreal membranes were seen, Nd:YAG laser photodisruption was performed in one eye of each rabbit, using the other eye as a control. The following results were obtained: Nd:YAG laser photodisruption of the vitreous hemorrhage in one eye of each rabbit led to much more rapid clearing than in the other (control) eye; the incidence of traction retinal detachment was much lower in the treated eyes compared with controls. The decision as to when to use photodisruption, based on ultrasonographic findings, was shown to be effective.
