The outcome and advantage of vitrectomy for traumatic macular hole

Purpose To observe the clinical effect and the advantage of vitrectomy for traumatic macular hole(MH).Methods Retrospectively study a series of 11 patients(11 eyes)of traumatic macular hole.Vitrectomy,inner limiting membrane(ILM)peeling and long-term gas temponade were performed.The vision outcome was statistically analyzed.OCT was used to observe the change of macular hole.Results The age was 16-56 months(36 ± 12.61)yrs.The course from trauma to operation was 1-12(4.59 ± 4.18)months.The pre-operative best corrected visual acuity(BCVA)was O.02-0.15,main(LogMAR 1.12 ± 0.26)and the post-operative one was 0.02 ～ 0.8,main(LogMAR 0.80 ± O.45),which was statistically improved(t = 3.761,P = 0.004).The size of mactlar hole was 336-1020 μm,main(671.36 ± 220.87)μm.The hole was closed in 10 eyes and it was still exist in 1 eye in which the size was 1020 μm preoperatively.The time for macular hole close was 5-30 d,main(17.42 ± 10.44)d.The visual acuity was increased for 0-2 lines in the patients older than 40 years,mainly(1 ± 1)line,in which the hole closed in 20-30 days(mean 26.5 ± 4.43 d).It was 2-8 lines in patients of ＜40 years old,and the hole closed in 5-28 d(main 14.8 ± 8.47 d).Conclusion Vitrectomy combined with ILM peeling can successfully seal the traumatic macular hole in short time and significantly improve the vision outcome.The bigger hole is difticulte to close,and the vision prognosis was poor in big hole and old patient.
