Peripheral visual field defects after macular hole surgery: a complication with decreasing incidence

Aim-To prospectively evaluate peripheral visual fields after vitrectomy for idiopathic macular holes. Methods-Goldmann perimetry was performed in 105 patients before, as well as 6 weeks and 12 months after macular hole surgery. Results-Only one patient (<1%) with a stage III macular hole developed an asymptomatic postoperative visual field defect. The scotoma was wedge-shaped, peripherally located in the temporal quadrant, and remained unchanged during the following 12 months. Conclusion-Peripheral visual field defects after macular hole surgery can be a complication of very low incidence. A rather low pressure set during air-fluid exchange as well as special aspects of the surgical technique may be responsible for this low incidence of peripheral visual field defects.
