白内障超声乳化术后黄斑区光学相干断层扫描观察

正常对照组黄斑区厚度(144.5±15.3)μm,白内障患者术前黄斑区厚度(143.9±16.8)μm,术后1周厚度(156.8±35.6)μm,术后1个月厚度(150.5±34.1)μm,超声高能量组术后1周厚度(171.6±31.5)μm,术后1个月厚度(169.8±30.5)μm,低能量组术后1周厚度(155.5±19.2)μm,术后1个月厚度(153.6±18.8)μm。13只眼出现房水中度闪光,术前厚度(142.8±10.5)μm,术后1周(196.4±35.7)μm。超声乳化白内障吸除术可导致术眼黄斑中心凹视网膜厚度增加及黄斑水肿;术中高超声能量可明显影响术后黄斑中心凹视网膜的厚度;术后黄斑中心凹视网膜厚度是预测术后视功能恢复的有效指标。

Observation of spectral-domain optical coherence tomography scanning after phacoemulsification cataract surgery

The preoperative mean fovea thickness was(143.9±16.8) μm and the normal control group was(144.5±15.3) μm.The mean fovea thickness was(156.8±35.6) μm at 1 week after operation,and(150.5±34.1) μm at 1 month after operation.13 eyes with Tyndall sign(+ +),the mean postoperative fovea thickness was(142.8±10.5) μm,1 week later,thickness was(196.4±35.7) μm.In lower phaco power group,the mean fovea thickness at 1 week after operation was(155.5±19.2) μm and it was(153.6±18.8) μm at 1 month after operation.In the higher phaco power group,the mean fovea thickness at 1 week after operation was(171.6±31.5) μm and it was(169.8±30.5) μm at 1 month after operation.The retinal thickening and macular edema can be found after uncomplicated phacoemulsification.The higher phaco power results in significant inflammation and thicker retina.The visual consequences are proportional to the degrees of macular thickening.
