Recently, optical coherence tomography (OCT) analysis has contributed greatly to the detection of posterior retinoschisis associated with optic disc pits. We report an unusual case of optic disc pit maculopathy.
A 37-year-old woman with a multilayered structure of posterior retinoschisis associated with a very small, shallow optic disc pit was treated.
The patient came to our clinic after a few weeks of decreased vision in her right eye. Fundus examination showed a shallow macular detachment with a tiny, shallow pit at the temporal edge of the optic disc. OCT revealed an unusual multilayered structure of retinoschisis connected to the optic disc. We performed vitrectomy with induction of the posterior hyaloid separation and gas tamponade. After vitrectomy, OCT showed a marked fluid resolution in the retinoschisis, and the patient's vision improved rapidly.
The multilayered separation of retinoschisis can be caused by traction of the optic disc with a tiny, shallow pit at the temporal edge of the disc.
最近，光学相干断层扫描（OCT）分析对视盘小凹相关的后部视网膜劈裂的检测有很大帮助。我们报告一例不寻常的视盘小凹黄斑病变病例。
一名37岁女性，患有与非常小且浅的视盘小凹相关的后部视网膜劈裂多层结构，接受了治疗。
患者右眼视力下降几周后前来我们诊所就诊。眼底检查显示黄斑浅脱离，视盘颞侧边缘有一个微小、浅的小凹。OCT显示与视盘相连的视网膜劈裂有不寻常的多层结构。我们进行了玻璃体切除术并诱导后玻璃体脱离和气液填充。玻璃体切除术后，OCT显示视网膜劈裂内的液体明显消退，患者视力迅速改善。
视网膜劈裂的多层分离可能是由视盘颞侧边缘微小、浅的小凹对视盘的牵拉引起的。
