BACKGROUND/OBJECTIVE: Accurate localization of retinal holes is essential for successful scleral buckling (SB) surgery. We aimed to verify the feasibility of using ultra-wide-field (UWF) imaging for preoperative estimation of retinal hole location.
We observed 21 eyes from 21 patients with rhegmatogenous retinal detachment (RRD) who underwent successful SB. They were treated at the Department of Ophthalmology of the Second Hospital of Hebei Medical University between November 2020 and November 2021. UWF fundus photography using an Optos device was performed at different steering positions 1 day before, 1 day after, and 1 month after SB. Using the preoperative fundus images, we measured the transverse diameter of the optic disc (D1) and the distance from the centre of the retinal holes to the ora serrata (D2). The accurate transverse diameter of the optic disc (Dd) was measured preoperatively using optical coherence tomography. The same surgeon measured the scleral chord lengths intraoperatively from the limbus to the located retinal hole marked on the sclera using an ophthalmic calliper. Statistical software was used to analyze the consistency of scleral chord length between the retinal hole and the limbus, which was estimated by preoperative UWF imaging and was measured using an ophthalmic calliper intraoperatively.
There was no statistically significant difference in the scleral chord length between the retinal holes and the limbus, which was estimated by preoperative UWF fundus photography and was measured by the calliper during surgery.
It is feasible to locate retinal holes using UWF fundus photography before SB, which is helpful for quick localization, thereby reducing the learning curve of SB surgery.
背景/目的：准确定位视网膜裂孔对于巩膜扣带术（SB）的成功至关重要。我们旨在验证使用超广角（UWF）成像术术前估计视网膜裂孔位置的可行性。
我们观察了 2020 年 11 月至 2021 年 11 月在河北医科大学第二医院眼科接受成功 SB 治疗的 21 例（21 只眼）孔源性视网膜脱离（RRD）患者。在 SB 术前 1 天、术后 1 天和 1 个月，使用 Optos 设备进行 UWF 眼底摄影，在不同的转向位置进行观察。使用术前眼底图像，我们测量了视盘的横向直径（D1）和视网膜裂孔中心到锯齿缘的距离（D2）。使用光学相干断层扫描术（OCT）术前准确测量视盘的横向直径（Dd）。同一位外科医生使用眼科卡尺从角膜缘到标记在巩膜上的定位视网膜裂孔，术中测量从角膜缘到定位视网膜裂孔的巩膜弦长。使用统计软件分析术前 UWF 成像术估计的和术中使用眼科卡尺测量的视网膜裂孔与角膜缘之间巩膜弦长的一致性。
术前 UWF 眼底摄影术估计的和术中使用眼科卡尺测量的视网膜裂孔与角膜缘之间的巩膜弦长无统计学差异。
在 SB 术前使用 UWF 眼底摄影术定位视网膜裂孔是可行的，有助于快速定位，从而缩短 SB 手术的学习曲线。
