To assess impact of duration of macular detachment on visual outcome after scleral buckling for retinal detachment with macula off.
Prospective, descriptive case series was conducted at Ophthalmology Department Dow University of Health Sciences, Civil Hospital Karachi and Al Noor Eye Clinic Karachi from May 2012 to June 2013. Five groups were made according to period of macular detachment. Best corrected Visual acuity (BCVA) was main outcome measure. P value < 0.001 was considered significant.
Mean duration of macula off was 17.0±4.0 (SD) days. Mean pre-operative VA in patients with immediate, early, intermediate, delayed or late group were 2/60, 2/60, Counting figure (CF) 3 meters (m), CF2 m and Hand Movement (HM) respectively. Only 48.48% patients of those repaired within 7 to15 days had significantly better (P < 0.001) BCVA (6/9-6/18) than the other groups. Only 19.35% patients of intermediate group achieved BCVA 6/18-6/24 (P < 0.001) which was comparatively better than the delayed and late group.
Scleral buckle surgery for macular-off Rhegmatogenous Retinal Detachment has good post-operative visual outcomes if repaired within two weeks.
评估黄斑脱离时间对巩膜扣带术治疗黄斑脱离视网膜脱离后视力结果的影响。
这是一项在 2012 年 5 月至 2013 年 6 月在巴基斯坦卡拉奇的道大学健康科学大学、卡拉奇民事医院和 Al Noor 眼科诊所眼科进行的前瞻性、描述性病例系列研究。根据黄斑脱离时间将患者分为五组。最佳矫正视力（BCVA）是主要观察指标。P 值<0.001 被认为具有统计学意义。
黄斑脱离的平均时间为 17.0±4.0（SD）天。即时、早期、中期、延迟或晚期组患者的术前 VA 平均值分别为 2/60、2/60、3 米（m）数指、2m 数指和手动（HM）。只有 48.48%的患者在 7 至 15 天内进行修复，其 BCVA（6/9-6/18）明显更好（P<0.001），优于其他组。只有 19.35%的中期组患者获得了 6/18-6/24 的 BCVA（P<0.001），与延迟和晚期组相比，这一结果相对较好。
对于黄斑脱离的孔源性视网膜脱离，巩膜扣带术如果在两周内进行修复，术后视力结果良好。
