PURPOSE
To report the incidence and clinical features of patients that experienced un-explained visual loss following silicone oil (SO) removal.
METHODS
Multicenter retrospective study of patients that underwent SO removal during 2000-2012. Visual loss of ≥2 lines was considered significant.
RESULTS
A total of 324 eyes of 324 patients underwent SO removal during the study period. Forty two (13%) eyes suffered a significant visual loss following SO removal. Twenty three (7.1%) of these eyes lost vision secondary to known causes. In the remaining 19 (5.9%) eyes, the loss of vision was not explained by any other pathology. Eleven of these 19 patients (57.9%) were male. The mean age of this group was 49.2 ± 16.4 years. Eyes that had an un-explained visual loss had a mean IOP while the eye was filled with SO of 19.6 ± 6.9 mm Hg. The length of time that the eye was filled with SO was 14.8 ± 4.4 months. In comparison, eyes that did not experience visual loss had a mean IOP of 14 ± 7.3 mm Hg ( < 0.0002) and a mean tamponade duration of 9.3 ± 10.9 months ( < 0.0001).
CONCLUSIONS
An un-explained visual loss after SO removal was observed in 5.9% of eyes. Factors associated with this phenomenon included a higher IOP and longer SO tamponade duration.
目的
报告硅油（SO）取出术后出现不明原因视力丧失患者的发生率及临床特征。
方法
对2000年至2012年期间接受SO取出术的患者进行多中心回顾性研究。视力下降≥2行被视为有显著意义。
结果
在研究期间，共有324例患者的324只眼接受了SO取出术。42只眼（13%）在SO取出术后出现了显著的视力丧失。其中23只眼（7.1%）因已知原因导致视力丧失。在其余19只眼（5.9%）中，视力丧失无法用任何其他病理情况解释。这19例患者中有11例（57.9%）为男性。该组患者的平均年龄为49.2±16.4岁。出现不明原因视力丧失的眼在眼内填充SO时的平均眼压为19.6±6.9mmHg。眼内填充SO的时间为14.8±4.4个月。相比之下，未出现视力丧失的眼的平均眼压为14±7.3mmHg（P<0.0002），平均填充时间为9.3±10.9个月（P<0.0001）。
结论
5.9%的眼在SO取出术后出现不明原因的视力丧失。与这种现象相关的因素包括较高的眼压和较长的SO填充时间。
