METHODS： One hundred and sixty-two consecutive patients （170 eyes） after primary operation for IMH were enrolled. Outcomes were classified as anatomical success when both IMH closure and restoration of the outer retinal structure were achieved. ＂Prospective＂ group included 108 patients （115 eyes） followed with optical coherence tomography （OCT） and microperimetry for ly after surgery. Potential prognostic criteria, except microperimetry data, were tested in ＂retrospective＂ group （54 patients, 55 eyes）. Prognostic value of each parameter was determined using receiver operating characteristic （ROC） analysis. Combined predictive power of the best prognostic parameters was tested with the use of linear discriminant analysis. RESULTS： IMH closure was achieved in 106 eyes （92%） in the prospective group and 49 eyes （89%） in the retrospective group. Despite anatomical closure, the outer retinal structure was not restored in two eyes in the first group and in one eye in the second group. Preoperative central subfield retinal thickness demonstrated the best discriminatory capability between eyes with anatomical success and failure： area under the ROC-curve （AUC） 0.938 （95% Ch 0.881-0.995）, sensitivity 64% at fixed specificity 95% （cut-off value 300um） in the prospective group; sensitivity 57% and specificity 90% in the retrospective group. Other continuous parameters except tractional hole index （AUC： 0.796, 95% Ch 0.591- 1.000） had significantly lower AUCs （P〈0.05）. The best combination of the parameters, established by discriminant analysis in the prospective group, could not confirm its predictive value in the retrospective group. CONCLUSION： Preoperative central subfield retinal thickness is a strong and probably the best predictor of anatomical results of IMH surgical treatment.展开更多
