【摘要】：目的使用深部增强成像频域光学相干断层扫描(enhanced depth imaging spectral domain optical coherence tomography,EDI SD-OCT)观察孔源性视网膜脱离成功复位1 a以上低视力患眼黄斑中心凹下脉络膜厚度(subfoveal choroidal thickness,SFCT),分析其与低视力的关系。方法将南昌爱尔眼科医院2010年1月到2014年3月孔源性视网膜脱离成功复位术后1 a以上最佳矫正视力(best corrected visual acuity,BCVA)0.3的患者72例(72眼)纳入研究。行双眼BCVA及EDI SD-OCT扫描SFCT检查。分析患眼与对侧健眼术后末次随访的BCVA与SFCT的相关性。结果患眼术后末次随访SD-OCT检查显示,72眼中,黄斑中心凹正常者3眼(4.2%);外层视网膜微结构异常者69眼(95.8%)。患眼术后末次随访BCVA,转换为5分记录视力为3.59±0.51,同期健眼为4.94±0.11;患眼术后末次随访SFCT为(164.47±62.95)μm,对侧健眼SFCT为(235.47±42.40)μm;患眼与对侧健眼术后末次随访BCVA、SFCT差异均有统计学意义(均为P0.05)。患眼术后末次随访BCVA与SFCT有相关性(P0.05)。患眼黄斑区外层视网膜微结构异常眼与正常眼的BCVA、SFCT差异均无统计学意义(均为P0.05)。结论孔源性视网膜脱离成功复位术后1 a以上低视力眼的SFCT薄,且与BCVA存在相关性;其视力的恢复可能要晚于EDI SD-OCT下观察到的外层视网膜微结构的恢复。
[Abstract]:Objective to observe the macular subfoveal choroidal thickness (subfoveal choroidal thickness,SFCT) in patients with rhegmatogenous retinal detachment (RRD) by deep enhanced imaging frequency domain optical coherence tomography (enhanced depth imaging spectral domain optical coherence tomography,EDI SD-OCT) after successful reattachment for more than a year. The relationship between low vision and low vision was analyzed. Methods from January 2010 to March 2014, 72 patients (72 eyes) with best corrected visual acuity (best corrected visual acuity,BCVA) 0.3 after successful reattachment of rhegmatogenous retinal detachment were enrolled in the study. Binocular BCVA and EDI SD-OCT scanning SFCT were performed. To analyze the correlation between BCVA and SFCT in the last follow-up between the affected eyes and the contralateral eyes. Results in 72 eyes, 3 eyes (4.2%) had normal macular fovea and 69 eyes (95.8%) had abnormal outer retinal microstructure. The final follow-up of SD-OCT showed that the macular fovea was normal in 3 eyes (4.2%). The recorded visual acuity was 3.59 卤0.51 at the last follow-up, 4.94 卤0.11 for the healthy eyes, (164.47 卤62.95) 渭 m for the SFCT and (235.47 卤42.40) 渭 m for the contralateral healthy eyes, and (164.47 卤62.95) 渭 m for the last follow-up of the eyes. The visual acuity (BCVA,) was (235.47 卤42.40) 渭 m for the contralateral healthy eyes. There was significant difference in BCVA,SFCT between the affected eyes and the contralateral eyes in the last follow-up (P0.05). There was a correlation between BCVA and SFCT in the last follow-up (P0.05). There was no significant difference in BCVA,SFCT between eyes with macular retinal microstructural abnormalities and normal eyes (P 0.05). Conclusion SFCT is thin in low vision eyes more than one year after successful reattachment of rhegmatogenous retinal detachment, and it is correlated with BCVA, and the recovery of visual acuity may be later than that of outer retinal microstructure observed under EDI SD-OCT.
