This study examined patients with permanent legal blindness in one eye after a previous eye surgery and those with permanent legal blindness in one eye for non-surgical reasons. The objective of this study was to assess the occurrence of complications both during and after surgery in patients undergoing phacoemulsification for cataracts or vitreoretinal surgery for retinal detachment in the fellow eye.
A retrospective study included 62 patients (group 1) with legal blindness in one eye, compared to 62 control patients (group 2) undergoing similar surgeries. Complications, history of complex surgery leading to legal blindness, and demographic characteristics were analyzed.
In group 1, the complication rate was significantly higher in patients who underwent both phacoemulsification and vitreoretinal surgeries than in group 2 (p < 0.05). In group 1, complications developed during surgery in the other eye in 28.1% of the patients whose permanent legal blindness stemmed from a complication in the previous surgery. In contrast, complications arose in the surgery of the other eye in 10% of patients whose permanent legal blindness did not result from any complications in the previous surgery. A statistically significant difference was observed between the two groups (P < 0.05).
In our study, if the cause of eye loss in patients with permanent legal blindness in one eye was a surgical complication, the possibility of complications during surgery in the other eye was high. Surgery can be planned at higher visual acuity levels in a patient who has lost one eye for reasons other than surgery. In patients who have lost one eye due to previous surgery, surgery for the other can be planned at lower visual acuity levels.
This is the first report to compare the rate of complications during and after surgery in patients with pre-existing permanent legal blindness in one eye who underwent cataract surgery and vitreoretinal surgery in the other.
本研究调查了既往眼部手术后单眼永久性法定失明的患者以及因非手术原因导致单眼永久性法定失明的患者。本研究的目的是评估在对另一只眼进行白内障超声乳化手术或视网膜脱离玻璃体视网膜手术的患者手术期间及术后并发症的发生情况。
一项回顾性研究纳入了62名单眼法定失明的患者（第1组），并与62名接受类似手术的对照患者（第2组）进行比较。分析了并发症、导致法定失明的复杂手术史以及人口统计学特征。
在第1组中，接受超声乳化手术和玻璃体视网膜手术的患者并发症发生率显著高于第2组（p < 0.05）。在第1组中，永久性法定失明源于既往手术并发症的患者中，28.1%在另一只眼手术期间出现并发症。相比之下，永久性法定失明并非由既往手术任何并发症导致的患者中，10%在另一只眼手术时出现并发症。两组之间观察到统计学显著差异（P < 0.05）。
在我们的研究中，如果单眼永久性法定失明患者的失明原因是手术并发症，那么另一只眼手术期间出现并发症的可能性很高。对于因非手术原因失去一只眼的患者，可以在较高视力水平时规划手术。对于因既往手术失去一只眼的患者，可以在较低视力水平时规划另一只眼的手术。
这是第一份比较既往单眼永久性法定失明患者在另一只眼进行白内障手术和玻璃体视网膜手术后手术期间及术后并发症发生率的报告。
