The exact pathogenesis of central retinal detachment associated with optic disc pit is still unknown. Vitrectomy has proven to be the most effective therapy.
In two patients with macular detachment associated with optic disc pit, a pars-plana-vitrectomy with surgical posterior vitreous detachment and gastamponade was performed. We report on the interesting clinical course of these patients.
After the gas bubble was absorbed, we observed a displacement of the subretinal fluid inferiorly in both patients. Schisislike changes persisted in the macular area. After several months the subretinal fluid resolved completely.
The fluid displacement and the resolution-characteristics of the subretinal fluid after vitrectomy in cases of retinal detachment associated with optic disc pit are completely different from other rhegmatogenous retinal detachments. The gas bubble separates the central retinoschisis from the peripheral rhegmatogenous part. The reason for delayed resolution remains unclear. It may be due to tangential vitreous traction in the periphery.
与视盘小凹相关的中心性视网膜脱离的确切发病机制仍不清楚。玻璃体切除术已被证明是最有效的治疗方法。
对两名患有与视盘小凹相关的黄斑脱离的患者进行了经平坦部玻璃体切除术，包括手术性玻璃体后脱离和气体填塞。我们报告了这些患者有趣的临床过程。
气泡吸收后，我们观察到两名患者的视网膜下液均向下移位。黄斑区持续存在劈裂样改变。数月后视网膜下液完全消退。
与视盘小凹相关的视网膜脱离病例在玻璃体切除术后视网膜下液的移位和消退特征与其他孔源性视网膜脱离完全不同。气泡将中心性视网膜劈裂与周边孔源性部分分开。消退延迟的原因尚不清楚。可能是由于周边玻璃体的切线牵引。
