All patients revealed grade I NS based on the Emery–Little classification. Mean patient age and refractive value just after surgery were 56.07 years and −0.33 diopters (D) in the DR group, and 57.06 years and −0.96 D in the non-DR group.Results: The Emery–Little classification in the DR group at 6 and 24 months postoperative were grade I (13 eyes)/grade II (one eye) and grade I (eleven eyes)/grade II (three eyes), respectively. Mean refractive values in the DR group at 6, 12, and 24 months postoperative were +0.28 D, +0.27 D, and +0.37 D, respectively. The Emery–Little classification in the non-DR group at 6 and 24 months (or preoperative for patients undergoing cataract surgery) were grade I (five eyes)/grade II (eight eyes) and grade I (zero eyes)/grade II (eight eyes)/grade III (five eyes), respectively. The mean refractive value in the non-DR group at 6 months postoperative was −3.20 D. All eyes exhibited myopic changes and progression of NS.Conclusion: The findings of this study show that the progression of NS postvitrectomy is mild, even for DR patients 50 years of age or older, thus suggesting the need to reconsider the indications for simultaneous cataract surgery with vitrectomy.Keywords: Emery–Little classificationIkeda TMinami MNakamura KKida TFukumoto MSato TIshizaki EDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2014, Iss default, Pp 959-963 (2014)
