Vitreoretinal surgery without schisis cavity excision for the management of juvenile X linked retinoschisis

Juvenile X linked retinoschisis (XLRS) is a congenital X linked recessive retinal disorder characterised by cystic maculopathy and peripheral schisis. This study presents the case of an 8-month-old boy with a documented positive family history of XLRS, with a large retinoschisis cavity affecting the macula, first in the left eye and 1 year later in the right eye. The patient underwent pars plana vitrectomy in both eyes using 23-G instruments, posterior hyaloid dissection, a small retinotomy, fluid drainage with a 42-G cannula, infrared diode laser and silicone oil as internal tamponade. The anatomical and functional outcomes at 3 years following the first surgery are described. To the authors' knowledge, there is no previously reported experience with this technique in patients with XLRS.
