To evaluate the possible hemodynamic changes following strabismus surgery via optical coherence tomography angiography.
Thirty-two eyes of 16 patients who underwent strabismus surgery in one eye were included in the study. Fellow eyes were used as a control group. The vessel densities of the superficial and deep capillary plexus and superficial and deep foveal avascular zones were measured preoperatively and 3 months postoperatively.
The mean superficial and deep foveal avascular zones measurements were 0.84 ± 0.09 and 0.76 ± 1.13 mm, respectively. The mean vessel density of the superficial capillary plexus was 1.23 ± 0.12 and 11.13 ± 1.04 mm preoperatively in the 1- and 3-mm zones, respectively, whereas the mean vessel density of the deep capillary plexus was 1.13 ± 0.16 and 10.11 ± 1.28 mm preoperatively. Postoperatively, the mean superficial and deep foveal avascular zones changed to 0.20 ± 0.13 and 0.23 ± 0.12 mm, respectively. Postoperatively, the mean vessel density of the superficial capillary plexus changed to 1.47 ± 0.11 and 12.75 ± 1.10 mm, and the mean vessel density of the deep capillary plexus changed to 1.56 ± 0.12 and 13.91 ± 1.35 mm in 1- and 3-mm zones, respectively. There was a statistically significant increase in vessel density measurements of the superficial and deep capillary plexus, and a statistically significant decrease in measurements of the superficial and deep foveal avascular zone postoperatively (P < .05). In the fellow eyes, there was no statistically significant change in any of the measurements (P > .05).
Following strabismus surgery, vessel density of the fovea may increase and the foveal avascular zone may decrease according to optical coherence tomography angiography measurements. [J Pediatr Ophthalmol Strabismus. 2019;56(2):95-100.].
通过光学相干断层扫描血管造影术评估斜视手术后可能出现的血流动力学变化。
本研究纳入了16例单眼接受斜视手术患者的32只眼。对侧眼作为对照组。术前及术后3个月测量浅表和深部毛细血管丛以及浅表和深部黄斑无血管区的血管密度。
浅表和深部黄斑无血管区的平均测量值分别为0.84±0.09和0.76±1.13mm。术前，1mm和3mm区域浅表毛细血管丛的平均血管密度分别为1.23±0.12和11.13±1.04mm，而深部毛细血管丛的平均血管密度为1.13±0.16和10.11±1.28mm。术后，浅表和深部黄斑无血管区的平均值分别变为0.20±0.13和0.23±0.12mm。术后，1mm和3mm区域浅表毛细血管丛的平均血管密度分别变为1.47±0.11和12.75±1.10mm，深部毛细血管丛的平均血管密度分别变为1.56±0.12和13.91±1.35mm。术后浅表和深部毛细血管丛的血管密度测量值有统计学显著增加，浅表和深部黄斑无血管区的测量值有统计学显著降低（P<.05）。在对侧眼中，任何测量值均无统计学显著变化（P>.05）。
根据光学相干断层扫描血管造影术测量结果，斜视手术后黄斑的血管密度可能增加，黄斑无血管区可能减小。[《小儿眼科与斜视杂志》。2019；56(2)：95 - 100。]
