Abstract

Objective: To compare the intraoperative and postoperative findings of 27-gauge pars plana vitrectomy (PPV) with those of 25-gauge PPV for the treatment of canine rhegmatogenous retinal detachment (RRD).

Methods: Dogs that underwent 27- or 25-gauge PPV for the treatment of RRD were included. The surgical procedure was divided into 4 sections (1, trocar placement; 2, vitrectomy and retinal reattachment; 3, silicone oil injection; and 4, scleral suturing). We compared intraoperative findings, anatomical and visual success rates, and postoperative complications between the 2 groups.

Results: 19 eyes (18 dogs) that underwent 27-gauge PPV and 20 eyes (19 dogs) that underwent 25-gauge PPV were included. Section 1 was significantly shorter with 27-gauge PPV than with 25-gauge PPV (4.1 ± 0.9 minutes vs 8.9 ± 2.0 minutes), but the overall surgical time was not significantly different. As for intraoperative findings, in section 2, 27-gauge PPV had significantly more incidents (5 eyes vs 0 eyes). The anatomical success rate was 100% in both groups, and the visual success rate was 78.9% for 27-gauge PPV and 85.0% for 25-gauge PPV, with no significant difference. There was no significant difference in the incidence of each postoperative complication between the 2 groups.

Conclusions: 27-gauge PPV was associated with shorter operative time in section 1 and more incidents in section 2 compared with 25-gauge PPV, but there were no significant differences in overall operative time or surgical outcomes.

Clinical relevance: 27-gauge PPV may be considered as a treatment option for canine RRD.

27号与25号玻璃体切割治疗犬孔源性视网膜脱离的比较。

目的：比较27号玻璃体切割（PPV）与25号玻璃体切割（PPV）治疗犬孔源性视网膜脱离（RRD）的术中、术后表现。方法：包括接受27或25号PPV治疗RRD的狗。手术过程分为4个部分(1，套管针置入；2、玻璃体切除和视网膜再植；3、硅油注入；4、巩膜缝合)。我们比较了两组的术中表现、解剖和视觉成功率以及术后并发症。结果：包括19只眼（18只狗）和20只眼（19只狗）进行了27号PPV和25号PPV。27径PPV组第1节明显短于25径PPV组（4.1±0.9分钟vs 8.9±2.0分钟），但总体手术时间无显著差异。至于术中发现，在第2节中，27号PPV的发生率明显更高（5只眼vs 0只眼）。两组解剖成功率均为100%，27号PPV的视觉成功率为78.9%，25号PPV的视觉成功率为85.0%，差异无统计学意义。两组术后各并发症发生率比较，差异无统计学意义。结论：与25径PPV相比，27径PPV在第1节的手术时间更短，在第2节的事件更多，但在总手术时间和手术结果上没有显著差异。临床相关性：27号PPV可能被认为是犬RRD的一种治疗选择。
