PURPOSE
To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD).
METHODS
The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD.
RESULTS
A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the asymptomatic left eye. One year later, the left eye developed a macular PVD, and OCT measurements showed a 16.7% decrease in the central foveal thickness, and increases in the pit depth by 20.5%, foveola diameter by 14.7%, and pit volume by 19.4%. The thicknesses of the macular subfields of the Early Treatment Diabetic Retinopathy Study were decreased by 13.0% in the central subfield and by 1.4%-6.6% in the other subfields.
CONCLUSION
The deepening and widening of the fovea after a macular PVD indicate that a PVD can alter the shape of the fovea.
目的
展示一例无症状性黄斑部玻璃体后脱离（PVD）后黄斑中心凹形态发生改变的病例。
方法
通过频域光学相干断层扫描（OCT）图像确定自发性黄斑PVD前后的黄斑中心凹形态。
结果
一名66岁男性，右眼有单侧黄斑裂孔，左眼无症状性黄斑部出现PVD。一年后，左眼发生黄斑PVD，OCT测量显示中心凹厚度减少16.7%，凹坑深度增加20.5%，中心小凹直径增加14.7%，凹坑体积增加19.4%。糖尿病视网膜病变早期治疗研究中黄斑亚区的厚度在中心亚区减少了13.0%，在其他亚区减少了1.4%-6.6%。
结论
黄斑PVD后黄斑中心凹的加深和扩大表明PVD可改变黄斑中心凹的形态。
