Temporary resolution of foveal schisis following vitrectomy with silicon oil tamponade in X‑linked retinoschisis with retinal detachment.

X‑linked retinoschisis (XLR) is an uncommon bilateral vitreoretinal dystrophy characterized by typical foveoschisis in all patients that may be associated with peripheral retinoschisis. A young male with XLR with retinal detachment in his right eye underwent 23 gauge pars plana vitrectomy with silicone oil tamponade. Postoperatively, best‑corrected visual acuity (BCVA) improved to 20/120 with an attached retina. Spectral‑domain optical coherence tomography showed macular thinning with the collapse of the schitic cavities with silicone oil in situ. Following silicone oil removal at 6 months follow‑up, the retina remained attached with a BCVA of 20/80 however the foveal schitic cavities reappeared. This unusual course has not been described previously.
