眼底彩色照相和光相干断层扫描评价眼外伤玻璃体视网膜手术后黄斑前膜

目的 探讨眼底彩色照相和光相干断层扫描图像(OCT)评价眼外伤患者玻璃体视网膜手术后黄斑前膜的临床意义。 方法 采用眼底彩色照相和OCT，观察我院2003年7月至2004年9月收治的139例(139只眼) 眼外伤患者玻璃体视网膜手术后的黄斑部形态。 结果 手术后1、2、3、6、12个月眼底彩色照相分别检查出黄斑前膜5、8、17、19、20只眼，OCT检查分别为7、10、20、26、27只眼，差异无统计学意义（χ2＝0.173，P＞0.05）。OCT检查发现8只眼（29.63%）黄斑前膜与视网膜完全粘附，27只眼（44.44%）神经上皮层水肿，黄斑中心凹厚度(290.18±288.05) μm。 结论 眼底彩色照相和OCT可以用于眼外伤患者玻璃体视网膜手术后的早期和长期随访。OCT对黄斑前膜结构和状态的了解，对其治疗有重要指导意义。 (中华眼底病杂志, 2006, 22: 236-238)

Fundus photochromy and optical coherence tomography in epimacular membrane of traumatic eyes following virtreoretinal surgery

Objective To evaluate the clinical application value of ocular fundus photochromy and optical coherence tomography (OCT) in epimacular membrane of traumatic eyes following vitreorential surgery. Methods Ocular fundus photochromy and OCT were used to observe the morphological changes of macula in 139 consecutive patients with unilateral ocular trauma after vitreoretinal surgery between July 2003 and September 2004. Results At the 1st, 2nd, 3rd, 6th, and 12th month postoperatively, epimacular membranes were found in 5, 8, 17, 19, 20 patients, respectively by using photochromy; and in 7, 10, 20, 26, 27 patients, respectively by using OCT. There was no significant difference in epimacular membrane between photochromy and OCT(χ2＝0.173，P>0.05). The results of OCT showed that epimacular membranes completely adhered to the macular region in 8 patients（29.63%）, and retinal neurosensory layer swelled in 12 patients（44.44%）with the fovea thickness of (290.18±288.05) μm. Conclusion Ocular fundus photochromy and OCT are helpful in observing and discovering the epimacular membrane after virtreoretinal surgery of the patients with traumatic retinal detachment during the early and long-term follow-up period; and OCT can provide important information of the structue and position of these epimacular membranes hence to conduct to appropriate treatment. (Chin J Ocul Fundus Dis, 2006, 22: 236-238)
