Abstract:
AIM: To make a contrast and then analyze the difference of optical coherence tomography (OCT) before and after vitreomacular traction syndrome (VTS) was performed.METHODS: The clinical date of 11 evaluable eyes of 11 patients with VTS who were diagnosed by OCT and underwent 25G vitreous surgery from January 2013 to January 2014 were retrospectively analyzed.Patients were followed up for an average of 6mo, to observe the visual acuity and OCT examination of the patient before and after operation.We compared the changes of retinal thickness and local morphology before and after operation.RESULTS: After vitreous retraction, 6 eyes improved, 2 eyes do not improve.One eye received macular membrane traction, in the operation the macular epiretinal membrane peeling, retrial membrane stripping and the triamcinolone acetonide intravitreal injection were given, but after the operation, the vision does not improve.Two eyes received vitreous combined with retinal macular membrane traction.In the operation, macular epiretinal membrane stripping was given, after the operation, visual acuity improved.The proportion of those with visual acuity of 0.1 or more increased from 46% before to 73% after the operation.Before operations, the mean central macular thickness was 619.27±195.13μm, 239.12±143.84μm after, which decreased significantly (P<0.05).CONCLUSION: Vitrectomy can effectively relieve the vitreous traction of the macula, and can prevent further decline in visual acuity and reduce macular edema as well as improve the visual acuity of some patients.So, OCT has important guiding significance on the diagnosis and prognosis of this group.
