Outcome of 25-gauge pars plana vitrectomy via a lateral approach without proptosis of the globe: A retrospective study in 72 dogs (78 eyes).

Objective: To evaluate the postoperative visual outcome and complications of 25-gauge pars plana vitrectomy (PPV) via a lateral approach without proptosis of the globe in dogs.

Medical records included signalment, follow-up time, etiology and duration of RRD, angle between the outermost trocar ports, immediate postoperative anatomic success rate, pre- and postoperative visual status, and postoperative complications.
