摘要

背景和目的：视网膜血管疾病与较低的分形维度（FD）有关。我们分析了鸟枪状脉络膜视网膜病变（BSCR）的断裂维度：这是一项回顾性队列研究。我们进行了光学相干断层血管造影（OCTA），并使用 ImageJ 分析了浅层毛细血管丛（SCP）、深层毛细血管丛（DCP）和绒毛膜（CC）的 FD。对于每个血管层，我们分析了是否存在 BSCR、受试者的年龄、性别和是否患有糖尿病，以确定哪些因素可以预测较低的 FD：我们将 28 只患有 BSCR 的眼睛（14 名患者）与 34 只对照组眼睛（17 名患者）进行了比较。在 SCP（1.584 [± 0.126] vs 1.706 [± 0.118]，P < 0.001）、DCP（1.637 [± 0.134] vs 1.780 [± 0.096]，P < 0.001）和 CC（1.884 [± 0.063] vs 1.917 [± 0.047]，P = 0.036）中，BSCR 的平均 FD 较低。SCP的FD每增加一年降低（0.005 [P = 0.014]）。男性患者的 FD-DCP 较低（0.101 [P = 0.043]）：结论：在 BSCR 中，分形分析表明 SCP、DCP 以及较小程度上的 CC 受到了严重影响。[眼科手术激光成像视网膜2024;55:XX-XX]。

Fractal Changes of the Retinal Microvasculature in Birdshot Chorioretinopathy.

Background and objective: Retinal vascular disorders are associated with lower fractal dimension (FD). We analyzed FD in birdshot chorioretinopathy (BSCR).

Patients and methods: This was a retrospective cohort study. We performed optical coherence tomography angiography (OCTA) and analyzed FD of the superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC) using ImageJ. For each vascular layer, we analyzed the presence of BSCR, subjects' age, sex, and presence of diabetes mellitus to determine which may predict lower FD.

Results: We compared 28 eyes (14 patients) with BSCR to 34 control eyes (17 patients). Mean FD of BSCR was lower in SCP (1.584 [± 0.126] vs 1.706 [± 0.118], P < 0.001), DCP (1.637 [± 0.134] vs 1.780 [± 0.096], P < 0.001), and CC (1.884 [± 0.063] vs 1.917 [± 0.047], P = 0.036). FD of SCP was lower per increasing year (0.005 [P = 0.014]). Male patients had lower FD-DCP (0.101 [P = 0.043]).

Conclusion: In BSCR, fractal analysis showed significant involvement of the SCP, DCP, and to a lesser extent the CC. [Ophthalmic Surg Lasers Imaging Retina 2024;55:646-651.].
