Vitrectomy combined with glial tissue removal at the optic pit in a patient with optic disc pit maculopathy: a case report

INTRODUCTION We present a case of a man with optic disc pit maculopathy, whose vision improved after vitrectomy combined with glial tissue removal from the optic pit area, and without the use of photocoagulation. CASE PRESENTATION A 45-year-old man complained of blurred vision, and ophthalmoscopy revealed a retinal detachment and retinoschisis extending from an optic disc pit through the macula in his left eye. He was diagnosed with optic disc pit maculopathy, and vitrectomy was performed. A posterior vitreous detachment was created, glial tissue at the optic pit was removed, and octafluoropropane (C3F8) was injected as a gas tamponade. The retinal detachment and retinoschisis disappeared after six months, and vision improved to 20/20 without any visual field defects (Goldmann perimetry). A cataractous lens was extracted 2 years after the vitrectomy, and vision has remained 20/20 for 10 years without any recurrence. CONCLUSION The removal of glial tissue during vitrectomy may be beneficial in patients with optic disc pit maculopathy.
