【 摘 要 】

Purpose: The inverted internal limiting membrane (ILM) flap technique is generally used to treat refractory macular holes (MHs). Recently, a case of macular pucker formation outside the ILM flap after using silicone oil was reported. Although the pucker formation was attributed to the silicone oil use in that case, here we report two cases of macular pucker that occurred after the inverted ILM flap technique was performed without silicone oil. In one case, the ILM flap and proliferated tissue was removed, followed by their histopathological examination. Observations: Two patients with MH underwent vitrectomies using the inverted ILM flap technique. In both patients, the visual acuity worsened postoperatively, and macular pucker formation, associated with the ILM flap, was observed. In one patient, visual acuity improved after ILM flap removal, and histopathological examination of the specimen indicated strong cellular proliferation between the ILMs. Conclusions and Importance: Following the inverted ILM flap technique, macular pucker may occur even without the use of silicone oil. Removal of the flap and associated proliferative tissue was effective and resulted in no recurrence of MH or pucker. Ophthalmologists should consider the possibility that tissues on the ILM may lead to macular pucker formation especially inside the flap, in the area between the ILMs.
