Abstract

Objectives: To investigate the macular imaging features in patients with unilateral myelinated retinal nerve fiber (MRNF) and high myopia syndrome.

Materials and methods: Six patients with unilateral MRNF and high myopia syndrome and 13 myopic controls were enrolled in this study. Spectral domain (SD) optical coherence tomography (OCT), SD enhanced depth imaging OCT, and OCT angiography (OCTA) imaging results of MRNF-affected eyes were compared with the fellow eyes and myopic controls.

Results: All patients had abnormal foveal reflex and/or ectopia. No significant difference in retinal thickness parameters were noted between the groups. In OCT scans, posterior vitreous detachment (PVD) was observed in 4 out of the 6 MRNF-affected eyes. Regarding OCTA parameters, only a significant increase in acircularity index was noted in myelinated eyes (p=0.01).

Conclusion: All patients demonstrated normal foveal contours, macular structure, and OCTA features except for a higher acircularity index. The incidence of PVD was notably increased in the myelinated eyes.

有髓视网膜神经纤维和高度近视综合征患儿的黄斑影像学特征。

目的：探讨单侧有髓鞘视网膜神经纤维（MRNF）和高度近视综合征患者的黄斑影像学特征。材料和方法：本研究纳入6例单侧MRNF和高度近视综合征患者和13例近视对照组。将受MRNF影响的眼睛的光谱域（SD）光学相干断层扫描（OCT）、SD增强深度成像OCT和OCTA成像结果与其他眼睛和近视对照进行比较。结果：所有患者均有中央凹反射异常和/或远视。两组之间的视网膜厚度参数没有显著差异。在OCT扫描中，6只受MRNF影响的眼睛中有4只观察到后玻璃体脱离（PVD）。关于OCTA参数，只有有髓眼的曲率指数显著增加（p=0.01）。结论：除了曲率指数较高外，所有患者的中央凹轮廓、黄斑结构和OCTA特征均正常。PVD的发生率在有髓鞘的眼睛中显著增加。

期刊介绍： The Turkish Journal of Ophthalmology (TJO) is the only scientific periodical publication of the Turkish Ophthalmological Association and has been published since January 1929. In its early years, the journal was published in Turkish and French. Although there were temporary interruptions in the publication of the journal due to various challenges, the Turkish Journal of Ophthalmology has been published continually from 1971 to the present. The target audience includes specialists and physicians in training in ophthalmology in all relevant disciplines.
