Retinal detachment and retinoschisis associated with optic disc pit in peripapillary staphyloma

Purpose: To determine the characteristics and clinical course of an eye with a peripapillary staphyloma and an optic disc pit associated with a retinal detachment (RD) and retinoschisis. Observations: A 44-year-old woman had a peripapillary staphyloma with a shallow RD and retinoschisis in her right eye. The optic disc was located in the peripapillary staphyloma with steep walls, and an optic disc pit was located on the temporal area of the optic disc cup. Optical coherence tomography (OCT) revealed a separation of the lamina cribrosa, herniated retinal tissue, and a subarachnoid space corresponding to the optic disc pit. Pars plana vitrectomy with laser photocoagulation around the temporal margin of the peripapillary staphyloma was performed to treat the RD, and the treatment was successful. Conclusion and importance: Clinicians should be aware that eyes with a RD and retinoschisis associated with a deep peripapillary staphyloma and an optic disc pit exist. The RD and retinoschisis can be successfully treated by vitrectomy.
