The evaluation of assistant effect of intraoperative optical coherence tomography in vitreous retinal surgery for macular disease / 中华眼底病杂志

ABSTRACT

Objective To evaluate the assistant effect ofintraoperative OCT (iOCT) in vitreous retinal surgery for macular disease.Methods A retrospective case study.A total of 71 patients (71 eyes) with macular disease who underwent vitrectomy in Eye Hospital of Wenzhou Medical University at Hangzhou from June 2015 to September 2016 were collected.There were 24 males (24 eyes) and 47 females (47 eyes),aged from 25 to 78 years,with the mean age of 63.35± 10.01 years.Among 71 eyes,there were 26 eyes with idiopathic macular hole,42 eyes with idiopathic epiretinal membrane,3 eyes with vitreomacular traction syndrome.The examination of iOCT was performed on the patients during 23G minimally invasive vitreoretinal surgery combined with internal limiting membrane peeling.Use observational method to compare the difference between result of iOCT and observation under the microscope,record the change of treatment strategy.Results Eight eyes (11.27％) iOCT results were different from the surgeon's observation,which including 5 eyes (62.50％) with idiopathic macular hole,2 eyes (25.00％) with idiopathic epiretinal membrane,1 eye (12.50％) with vitreomacular traction syndrome.The treatment strategy was changed in 8 eyes (11.27％) based on iOCT result,which including 5 eyes (62.50％) with idiopathic macular hole,2 eyes (25.00％) with idiopathic epiretinal membrane,1 eye (12.50％) with vitreomacular traction syndrome.Conclusions iOCT can help the surgeon find some subtle morphological changes which can hardly be seen by eyes.The surgeon can change and optimize the treatment strategy based on the result of iOCT.
