To compare idiopathic full-thickness macular hole (FTMH) closure rates and postoperative best-corrected visual acuity (BCVA) between spectral domain optical coherence tomography (SD-OCT)-guided facedown posturing and conventional 1-week facedown posturing after macular hole surgery.
A retrospective comparative study.
Thirty-one consecutive eyes that underwent surgery for FTMH between July 2013 and September 2014 were divided into 2 groups.
In the SD-OCT-guided group, SD-OCT was performed on the first day after surgery. If the macular hole was closed, the patient could assume any position but supine. If the hole was not closed on postoperative day 1, SD-OCT was performed daily for 1 week until the hole was closed, at which point the patient was asked to stop positioning. For the control group, patients were asked to keep facedown posturing for 1 week after surgery.
Mean length of follow-up for the SD-OCT-guided group and the control group was 188.3 (SD = 74.6) days and 216.7 (SD = 71.2) days, respectively. FTMH closure rate was 100% for both groups. Mean time for FTMH closure in the SD-OCT group was 1.2 days. There was no statistical difference in postoperative BCVA at the last visit between SD-OCT-guided (0.49 ± 0.3 logMAR) and control (0.50 ± 0.4 logMAR; p = 0.9422) groups.
No difference in FTMH closure rates was detected between the SD-OCT-guided facedown posturing group and the control group. SD-OCT-guided posturing may be used to shorten facedown positioning while maintaining a high success rate.
比较黄斑裂孔手术后,频域光学相干断层扫描(SD - OCT)引导下的俯卧位姿势与传统的术后1周俯卧位姿势对特发性全层黄斑裂孔(FTMH)的闭合率及术后最佳矫正视力(BCVA)的影响。
一项回顾性对照研究。
2013年7月至2014年9月间连续接受FTMH手术的31只眼睛被分为两组。
在SD - OCT引导组中,术后第一天进行SD - OCT检查。如果黄斑裂孔闭合,患者可采取除仰卧位以外的任何姿势。如果术后第1天裂孔未闭合,则每天进行SD - OCT检查,持续1周,直到裂孔闭合,此时要求患者停止姿势摆放。对于对照组,患者术后需保持俯卧位姿势1周。
SD - OCT引导组和对照组的平均随访时间分别为188.3(标准差 = 74.6)天和216.7(标准差 = 71.2)天。两组的FTMH闭合率均为100%。SD - OCT组FTMH闭合的平均时间为1.2天。SD - OCT引导组(0.49±0.3 logMAR)和对照组(0.50±0.4 logMAR;p = 0.9422)在最后一次随访时的术后BCVA无统计学差异。
SD - OCT引导下的俯卧位姿势组与对照组在FTMH闭合率上未发现差异。SD - OCT引导的姿势摆放可用于缩短俯卧位姿势时间,同时保持较高的成功率。
