To investigate the relationship between early postoperative macular morphology and postoperative visual acuity in eyes that had undergone successful macular hole (MH) surgery.
Pars plana vitrectomy and internal limiting membrane peeling were performed during surgery for idiopathic MHs on 25 eyes. The macular configuration was determined by optical coherence tomography, and best-corrected VA (BCVA) was measured postoperatively.
Eleven eyes had nearly normal foveal morphology (normal group) and 14 eyes had subretinal fluid or intraretinal cysts (abnormal group) at 1 month. Among the 14 eyes in the abnormal morphology group, normal foveal morphology was confirmed in 9 eyes 3 months and in the remaining 5 eyes 6 months after surgery. Mean BCVA improved significantly from the preoperative values in both groups 6 months after surgery.
The morphology of the macular area was abnormal in more than one half of eyes that had successful MH surgery 1 month after surgery. However, by 6 months, all eyes had normal macular configuration, and BCVA was not significantly different in the two groups. We conclude that an abnormal morphologic appearance of the macular area in the early postoperative period does not predict the final visual outcome.
探讨成功进行黄斑裂孔(MH)手术的患眼中,术后早期黄斑形态与术后视力之间的关系。
对25例特发性MH患者行玻璃体切割术及内界膜剥除术。通过光学相干断层扫描确定黄斑形态,并在术后测量最佳矫正视力(BCVA)。
术后1个月时,11只眼黄斑中心凹形态接近正常(正常组),14只眼存在视网膜下液或视网膜内囊肿(异常组)。在形态异常组的14只眼中,术后3个月时9只眼黄斑中心凹形态恢复正常,其余5只眼在术后6个月时恢复正常。术后6个月时,两组的平均BCVA均较术前显著提高。
超过半数成功进行MH手术的患眼在术后1个月时黄斑区形态异常。然而,到术后6个月时,所有患眼黄斑形态均恢复正常,且两组的BCVA无显著差异。我们得出结论,术后早期黄斑区形态异常并不能预测最终的视力结果。
