The anterior part of the left eye was normal on slit lamp examination. Funduscopic examination revealed optic disc pit associated with macular detachment. The patient was treated with vitrectomy, internal limiting membrane (ILM) peeling and gas tamponade. One week after treatment, the patient presented with central visual disturbance and showed a full thickness macular hole in the left eye. Extensive ILM peeling and silicone oil instillation were performed and after 2 months, silicone oil removal was performed. The macular hole appeared to be closed and visual acuity improved to 0.2. Recurrence was not observed until 20 months after treatment.
