The vitreoretinal surgery for traumatic macular hole retinal detachment

Abstract

Objective To observe the clinical effect and visual function of vitrectomy combined with internal limiting membrane peeling for traumatic macular hole retinal detachment. Methods The clinical data of 30 eyes of 30 patients with traumatic macular hole retinal detachment who had undergone vitrectomy combined with internal limiting membrane peeling were analyzed retrospectively. The visual acuity and changes of macular area optical coherence tomonraphy (OCT) and multifocal electroretinogram (mfERG) in pre-operation and post-operation were observed.The follow-up time was 12 months. Results The retinal reattachment rate after surgery was 80.00%. Most of the patients achieved a better final visual acuity.Mf-ERG showed the response densities of ring 2, ring 3, and ring 4 areas of N1 wave and ring 2, ring 3, ring 4 and ring 5 areas of P1 wave in postoperative group were significantly increased while the latencies of ring 4 of N1 wave and the latencies of ring 3, ring 4 and ring 5 of P1 wave were significantly different with that of preoperative group (P<0.05). Conclusion Vitrectomy combined with internal limiting membrane peeling for traumatic macular hole retinal detachment is effective with fewer complications and can significantly improve visual function.
