Posterior microphthalmos is a rare congenital malformation characterized by normal anterior segment dimensions with an abnormally small posterior segment resulting in high hyperopia. Reduced visual acuity in these cases is sometimes caused by the presence of papillomacular retinal folds. We report two cases of posterior microphthalmos in which the papillomacular folds could be visualized on spectral domain optical coherence tomography with sufficient detail to illustrate that only the layers of neural retina within the external limiting membrane were involved.
后部小眼球是一种罕见的先天性畸形,其特征为眼前节尺寸正常而后节异常小,导致高度远视。这些病例中的视力下降有时是由视乳头黄斑视网膜皱褶的存在引起的。我们报告了两例后部小眼球病例,其中视乳头黄斑皱褶在光谱域光学相干断层扫描上能够清晰显示,足以表明仅外部限制膜内的神经视网膜层受累。
