[Visual field defect following macular hole surgery].

We report three patients with inferotemporal visual field defect following pars plana vitrectomy for idiopathic macular hole. Two patients complained of the visual field defect early in the postoperative period, and one patient was asymptomatic but showed abnormalities in perimetry. The visual field defect remained unchanged during a follow-up study of 4 to 12 months. It is possible that inadvertent damage to the optic nerve associated with air/ fluid exchange or hyaloid membrane stripping caused the characteristic visual field defect.
