牙疼后急性黄斑旁中层黄斑病变1例
|
Abstract:
患者男性，因牙疼后出现右眼视力模糊，眼前固定性暗影遮挡，检查发现右眼底黄斑区下方约2/3 PD范围的三角形的黄白色病灶、其两旁小分支血管梗塞，经光学相干断层成像(optical coherence tomography, OCT)检查示黄斑区下方内核层带状高反射信号，诊断为急性黄斑旁中层黄斑病变(paracentral acute middle maculopathy, PAMM)，经活血化瘀，改善微循环，营养神经治疗后好转，患者视力改善。
A male patient developed blurred vision in his right eye and fixed shadow occlusion after toothache. A triangular yellow and white lesion with a range of 2/3 PD below the macular area of his right eye and infarction of small branches on both sides was detected by optical coherence tomography. OCT examination showed high banding reflex signal in the lower kernel layer of macular area, which was diagnosed as paracentral acute middle maculopathy (PAMM). After activating blood circulation and removing blood stasis, improving microcirculation, it was improved after neurotrophic therapy.
