Here we document 2 cases of macular schisis-like appearance in high myopia analyzed with spectral domain optical coherence tomography (SDOCT).
In Case 1, a 58-year-old patient with high myopia manifesting a recent onset of decreased vision in the right eye (OD) is presented. In Case 2, a 45-year-old patient with a lifelong history of no light perception and high myopia OD is presented.
In Case 1, biomicroscopy found a posterior staphyloma associated with subtle retinal thickening in the patient's right eye. SDOCT confirmed the presence of macular traction associated with a schisis-like appearance. In Case 2, a posterior staphyloma associated with significant macular thickening was observed during biomicroscopy. SDOCT found macular traction and a schisis-like appearance.
These presentations are consistent with myopic traction maculopathy. Few myopic traction maculopathy cases have been studied with SDOCT. The time domain optical coherence tomography and SDOCT analysis suggests that the etiology of this condition may be secondary to preretinal and extraretinal traction exhibited in degenerative high myopia.
本文记录了2例高度近视患者黄斑劈裂样外观的病例，并采用频域光学相干断层扫描（SDOCT）进行分析。
病例1为一名58岁高度近视患者，近期右眼（OD）视力下降。病例2为一名45岁患者，右眼自幼无光感且患有高度近视。
病例1中，生物显微镜检查发现患者右眼存在后巩膜葡萄肿，并伴有细微的视网膜增厚。SDOCT证实存在与劈裂样外观相关的黄斑牵拉。病例2中，生物显微镜检查观察到后巩膜葡萄肿伴有明显的黄斑增厚。SDOCT发现黄斑牵拉和劈裂样外观。
这些表现符合近视性牵拉性黄斑病变。很少有近视性牵拉性黄斑病变病例采用SDOCT进行研究。时域光学相干断层扫描和SDOCT分析表明，这种情况的病因可能继发于退行性高度近视中视网膜前和视网膜外的牵拉。
