Abstract Purpose:To discuss two cases of macular hole(MH)formation after vitrectomy and spontaneous closure.

Case 1:A 70-year-old man with epiretinal membrane(ERM)underwent a vitrectomy without internal limiting membrane(ILM)peeling combined with cataract surgery in the right eye. The axial length was 27.04 mm. The postoperative best-corrected visual acuity(BCVA)was 0.9, but ERM was slowly relapsing. At postoperative 3 years 6 month, his BCVA was 0.2 with an 80 μm MH(the base diameter was 1,100 μm). The MH closed spontaneously next month and the BCVA improved to 0.4 4 months later. However, at postoperative 4 years 1 month, the 95 μm MH(the base diameter was 1,020 μm)reopened and the BCVA declined to 0.2 2 months later. At postoperative 4 years 4 month, the patient underwent vitrectomy with ERM and ILM peeling and gas tamponade, resulting in return of MH closure and BCVA improvement to 0.6.

Case 2:A 55-year-old man with a macula-on rhegmatogenous retinal detachment had a vitrectomy combined with cataract surgery in the right eye. The axial length was 25.94 mm. The postoperative BCVA was 1.5. One year later, he presented with a small, 140 μm MH(the base diameter was 550 μm)and BCVA declined to 0.8. Two months later, the MH spontaneously resolved and BCVA improved to 1.2.

 In two cases, cystoid macular edema and ERM or preretinal tissue proliferation were found at the opening of the MH.

Conclusion:These cases suggest that the possible mechanism of MH formation following vitrectomy is tangential traction by ERM, and that of MH closure is bridging of the inner retinal tissue.
