title: Local biometric features and visual prognosis after surgery for treatment of myopic foveoschisis.
abstract: OBJECTIVE
  To identify the local biometric factors associated with postoperative best-corrected visual acuity (BCVA) after surgical treatment of myopic foveoschisis by using spectral-domain optical coherence tomography.
  
  
  METHODS
  Eleven eyes of 10 patients that underwent vitrectomy combined with internal limiting membrane peeling for treatment of myopic foveoschisis were investigated. We measured the height and lateral width of the foveal detachment, subfoveal choroidal thickness, and height of the posterior staphyloma using spectral-domain optical coherence tomography.
  
  
  RESULTS
  Foveal detachments found in 8 eyes were not significantly related to postoperative BCVA. Intraclass correlation coefficients of spectral-domain optical coherence tomography measurements were substantial to nearly perfect (0.786-0.951). The postoperative BCVA 12 months after surgery was significantly correlated with age (r(s) = 0.616, P = 0.044), preoperative BCVA (r(s) = 0.833, P = 0.001), preoperative subfoveal choroidal thickness (r(s) = -0.661, P = 0.027), and posterior staphyloma height (r(s) = 0.642, P = 0.033). Neither postoperative BCVA nor changes in BCVA showed significant correlations with the axial length or height or lateral width of the foveal detachment.
  
  
  CONCLUSIONS
  These results at least raise the possibility that a thin choroid and likely severe posterior staphyloma before surgery can predict postoperative BCVA after vitrectomy for the treatment of myopic foveoschisis.
