Visual field loss after pars plana vitrectomy with air/fluid exchange.
OBJECTIVE
To report the postoperative finding of a dense, permanent, peripheral temporal visual field defect in the treated eyes of three patients who underwent pars plana vitrectomy with air/fluid exchange.


METHODS
The patient's charts were reviewed.


RESULTS
Visual field loss after pars plana vitrectomy and air/fluid exchange occurs and may be caused by mechanical trauma to the optic nerve head.


CONCLUSIONS
Great caution is advised when aspirating directly over the optic nerve with any extrusion instrument.
