  • Title: Pars plana vitrectomy for macular schisis associated with peripapillary intrachoroidal cavitation.
    Author: Yoshizawa C, Saito W, Noda K, Ishida S.
    Journal: Ophthalmic Surg Lasers Imaging Retina; 2014; 45(4):350-3. PubMed ID: 24972183.
    Abstract:
    A case of retinoschisis associated with peripapillary intrachoroidal cavitation (ICC) was successfully treated with pars plana vitrectomy. A 70-year-old woman developed macular elevation and peripapillary ICC in her right eye. Optical coherence tomography revealed retinoschisis with retinal detachment in the macula. A microhole was observed within the myopic conus. A narrow passage was observed linking the ICC with the schisis cavity, complicated by a peripapillary epiretinal membrane tissue adjacent to the passage. The patient underwent vitrectomy with removal of the membrane tissue. Complete regression of the retinoschisis was observed, with closure of the connection channel between the ICC and schisis cavity. These findings suggest that the communication channel between the vitreous and schisis cavities was formed due to the traction exerted by the membrane tissue on the ICC that had generated a connecting path to the schisis cavity.
