目的：分析局部治疗无效的糖尿病视网膜病变（DR）眼的脉络膜血管层：分析局部治疗无效的糖尿病视网膜病变（DR）眼脉络膜血管层的解剖结构：方法：回顾性临床病例对照研究：方法：该研究共纳入了 228 名未接受过治疗的 DR 患者的 328 只眼睛和 174 名健康对照者的 192 只轴向长度匹配的眼睛。使用增强型深度成像光学相干断层扫描（EDI-OCT）对脉络膜结构进行定量分析。每个脉络膜血管层被分为脉络膜瓣、Sattler层和Haller层，然后使用二值化技术计算脉络膜面积（CA）、管腔面积（LA）、基质面积（SA）和脉络膜中心厚度（CCT）。LA 与 CA 的比值被定义为 L/C 比值：在脉络膜瓣中，轻度/中度非增殖性DR（mNPDR）组的CA明显低于对照组，而所有DR组的SA都明显高于对照组（P均<0.01）。所有 DR 组的 L/C 比值都明显低于对照组（P < 0.01）。在 Sattler 层，重度 NPDR（sNPDR）组和 PDR 组的 CA、LA 和 SA 明显高于对照组（P＜0.01）。在霍勒层，PDR 组的 L/C 比值明显偏高（P < 0.05）：二值化方法得出的DR患者脉络膜参数与DR的分期有关，其中绒毛膜管腔在所有DR分期中都有所减少。DR晚期眼球中出现的CA扩张主要是由于Sattler层和Haller层发生了变化。

<div><h3>Objective</h3><div>This study aims to assess morphometric variations in bony nasolacrimal ducts (BNLDs) and sinonasal anatomy in Asian patients with unilateral primary acquired nasolacrimal duct obstruction (PANDO) through computed tomography (CT).</div></div><div><h3>Methods</h3><div>We enrolled 34 patients with unilateral PANDO who underwent endoscopic dacryocystorhinostomy, alongside 34 age- and sex-matched control patients without documented epiphora complaints. We compared BNLD and sinonasal parameters on CT images between the affected and unaffected sides of PANDO patients and the control group.</div></div><div><h3>Results</h3><div>The entrance area of the BNLD was larger on the affected side of unilateral PANDO patients compared to both the unaffected side (<em>p</em> = 0.012) and the control group (<em>p</em> = 0.046). The open angle in the coronal plane was greater on both the affected (<em>p</em> = 0.044) and unaffected side (<em>p</em> = 0.028) than in the control group. Minimal area and distal area in the axial plane showed no differences among the 3 groups. Paranasal parameters did not differ between the study and control groups. More patients in the study group had superiorly located nasal septum deviation than the control group (<em>p</em> = 0.048). A trend suggested that more patients in the study group had anteriorly located nasal septum deviation than the control group (<em>p</em> = 0.056), although not reaching statistical significance.</div></div><div><h3>Conclusion</h3><div>The increased angular tilt in PANDO patients could impede fluid drainage from a fluidics standpoint. The larger BNLD area on the affected side reflects inflammation-induced osteolysis. Additionally, sinonasal variations, particularly nasal septum deviation at the anterior and superior half, have been identified as contributing to a higher risk of PANDO.</div></div><div><h3>Objectif</h3><div>Notre étude a eu recours à la tomographie assistée par ordinateur pour évaluer les variations morphométriques du canal nasolacrymal osseux (CNLO) et de l'anatomie nasosinusienne chez des patients asiatiques présentant une sténose acquise non spécifique du canal lacrymonasal (PANDO, pour <em>primary acquired nasolacrimal duct obstruction</em>) unilatérale.</div></div><div><h3>Méthodes</h3><div>Nous avons recruté 34 patients atteints d'une PANDO unilatérale qui ont subi une dacryocystorhinostomie endoscopique ainsi que 34 sujets témoins sans larmoiement avéré et appariés pour l’âge et le sexe.
