Vitrectomy with peripapillary internal limiting membrane peeling for macular retinoschisis associated with normal-tension glaucoma

Purpose: Although vitrectomy has been reported to be effective for the treatment of macular retinoschisis associated with glaucoma in a few case series, the surgical techniques have yet to be established. This article aimed to describe the cases of two patients with macular retinoschisis who underwent vitrectomy with peripapillary internal limiting membrane peeling around the defective area of the retinal nerve fiber layer. Observations: Both patients had been diagnosed with normal tension glaucoma and treated with eye drops to stabilize intraocular pressure. Progression of macular retinoschisis and accompanied vision loss were observed in both cases. Twelve months after the surgery, both patients had resolution of the retinoschisis and improvement in best corrected visual acuity. Conclusions and importance: Our surgical technique may be effective for the resolution of macular retinoschisis in eyes with normal tension glaucoma.
