A 65-year-old patient complained of central metamorphopsia and presented an intraretinal cyst with a yellow ring in the fovea of the right eye. His best-corrected visual acuity was 20/32 in that eye. Optical coherence tomography (OCT) 3 showed an enlarged pseudocyst at the outer retina of a stage 1B macular hole; the foveal roof was intact where the vitreous was attached reflecting a perifoveal posterior vitreous detachment. Six months later, OCT 3 showed bridging by centripetal protrusion in the outer fovea inside the pseudocyst with a residual defect in the foveal photoreceptor layer. Eighteen months after the initial visit, spectral-domain OCT showed bridging of the outer retina inside the pseudocyst at the hyper-reflective line representing the external limiting membrane; the roof of the pseudocyst was more elevated with posterior hyaloid adhesion and there was a smaller residual defect in the foveal photoreceptor layer. This case demonstrates that spontaneous closure in the outer retina may develop in some cases of stage 1B macular holes without vitreofoveal separation.
一位65岁的患者主诉有中心性视物变形,右眼黄斑中心凹可见一个带有黄色环的视网膜内囊肿。该眼最佳矫正视力为20/32。光学相干断层扫描(OCT)3显示1B期黄斑裂孔外视网膜有一个扩大的假性囊肿;黄斑中心凹顶部完整,玻璃体附着处反射出中心凹周围玻璃体后脱离。6个月后,OCT 3显示假性囊肿内中心凹外有向心性突出形成桥接,黄斑感光层有残余缺损。初诊18个月后,频域OCT显示假性囊肿内代表外界膜的高反射线处外视网膜桥接;假性囊肿顶部因后玻璃体粘连而抬高更明显,黄斑感光层残余缺损较小。该病例表明,在一些没有玻璃体黄斑分离的1B期黄斑裂孔病例中,外视网膜可能会自发闭合。
