PURPOSE To determine if paracentral acute middle maculopathy (PAMM) and peripapillary intraretinal and subretinal fluid (IRF/SRF) could help distinguish between arteritic anterior ischemic optic neuropathy (A-AION) and non-arteritic AION (NA-AION) at an early stage. DESIGN Nested prospective cross-sectional diagnostic accuracy study. METHODS This study used single-center optical coherence tomography (OCT) data from 8 patients with A-AION and 24 patients with NA-AION from two prospective cross-sectional studies with consecutive sampling (ClinicalTrials.gov: NCT05248906 and NCT05305079). The diagnosis of A-AION was based on expert interpretation of biochemical markers of inflammation, temporal artery biopsy and positron emission tomography/computed tomography. The diagnosis of NA-AION was made in cases without suspicion or clinical evidence of A-AION and with confirmed neuroophthalmological expert diagnosis. For this substudy patients were also required to have an OCT scan in relation to the diagnosis of AION. Macular OCT scans were graded by two independent, masked graders for the presence of PAMM and for IRF/SRF. The extension of IRF/SRF was assessed using an Early Treatment Diabetic Retinopathy Study (ETDRS) grid. RESULTS PAMM was found in 50% of patients with A-AION and in 0% of patients with NA-AION (P = 0.0019). In the setting of AION, the sensitivity of PAMM for the diagnosis of A-AION was 50% (95%CI: 16 to 84%) while the specificity was 100% (95%CI: 86 to 100%). Conversely, peripapillary IRF/SRF with extension into the ETDRS grid was observed in 83% of patients with NA-AION but in 0% of patients with A-AION (P =0.000047). The sensitivity of central macula-involving IRF/SRF for the diagnosis of NA-AION was 83% (95%CI: 63 to 95%), while the specificity was 100% (95%CI: 63 to 100%). Combining the two biomarkers, 75% of patients with AION could be classified based on OCT alone. CONCLUSION PAMM appears to be a biomarker of A-AION while extensive peripapillary fluid appears to be a biomarker of NA-AION. Combining OCT biomarkers might allow for early classification of AION and warrants further prospective studies.

结合中央旁急性中黄斑病变和周围液作为前部缺血性视神经病变的生物标志物:前部缺血性视神经病变中的 OCT 生物标志物。



目的 确定中央旁急性中黄斑病变 (PAMM) 和周围视网膜内和视网膜下液 (IRF/SRF) 是否有助于在早期区分动脉炎性前缺血性视神经病变 (A-AION) 和非动脉炎性 AION (NA-AION)。设计 嵌套前瞻性横断面诊断准确性研究。方法 本研究使用了来自两项连续采样的前瞻性横断面研究 (ClinicalTrials.gov: NCT05248906 和 NCT05305079) 的 8 例 A-AION 患者和 24 例 NA-AION 患者的单中心光学相干断层扫描 (OCT) 数据。A-AION 的诊断基于对炎症生化标志物、颞动脉活检和正电子发射断层扫描/计算机断层扫描的专家解释。NA-AION 的诊断是在没有 A-AION 怀疑或临床证据且经神经眼科专家确诊的病例中做出的。对于该子研究,患者还需要进行与 AION 诊断相关的 OCT 扫描。黄斑 OCT 扫描由两名独立的蒙面分级员对 PAMM 和 IRF/SRF 的存在进行分级。使用早期治疗糖尿病视网膜病变研究 (ETDRS) 网格评估 IRF/SRF 的扩展。结果 在 50% 的 A-AION 患者和 0% 的 NA-AION 患者中发现 PAMM (P = 0.0019)。在 AION 的情况下,PAMM 诊断 A-AION 的敏感性为 50% (95% CI: 16 至 84%),而特异性为 100% (95% CI: 86 至 100%)。相反,在 83% 的 NA-AION 患者中观察到周围 IRF/SRF 延伸到 ETDRS 网格,但在 0% 的 A-AION 患者中观察到 (P =0.000047)。 累及中央黄斑的 IRF/SRF 诊断 NA-AION 的敏感性为 83% (95% CI: 63 至 95%),而特异性为 100% (95% CI: 63 至 100%)。结合这两种生物标志物,75% 的 AION 患者可以单独根据 OCT 进行分类。结论 PAMM 似乎是 A-AION 的生物标志物,而广泛的周围液似乎是 NA-AION 的生物标志物。结合 OCT 生物标志物可能允许对 AION 进行早期分类,并保证进一步的前瞻性研究。
