  • 简介:目的:研究巩膜扣带术(scleralbuckling,SB)联合玻璃注气术治疗孔源性视网膜脱离(rhegmatogenousretinaldetachment,RRD)的临床疗效及对患者血清中氨基酸、血管内皮生长因子(vascularendothelialgrowthfactor,VEGF)的影响。方法:回顾性分析我院收治的RRD患者150例150眼临床资料,将仅接受SB的患者81例81眼纳入未注气组,接受SB+玻璃注气术的患者69例69眼纳入注气组,比较组患者手术疗效和术前、术后血清中氨基酸、VEGF水平等情况。结果:组患者术后各时间点视网膜复位率比较,差异均无统计学意义(P>0.05);注气组术后1d眼压明显高于未注气组,差异有统计学意义(P<0.05),组患者术后5d眼压比较差异无统计学意义(P>0.05);组患者术后术眼裸眼视力较术前均明显改善,差异有统计学意义(P<0.05);术后5d,组患者血清中组氨酸、谷氨酸、苯丙氨酸、VEGF水平较术前均显著降低,差异有统计学意义(P<0.05),但组间比较差异无统计学意义(P>0.05);组患者血清中精氨酸、亮氨酸、异亮氨酸、甘氨酸水平与术前比较,差异无统计学意义(P>0.05);术后1mo,组患者视功能相关生活质量总分和各维目评分均较术前明显升高,差异有统计学意义(P<0.05),但组间各评分比较差异无统计学意义(P>0.05);注气组术后并发症总发生率为7.2%(5/69)与未注气组的9.9%(8/81)比较,差异无统计学意义(P>0.05)。结论:SB联合玻璃注气术有助于RRD患者视功能和眼压的早期恢复,降低血清中组氨酸、谷氨酸、苯丙氨酸、VEGF水平,且安全性较高。

  • 简介:目的比较周边虹膜切除术与超声乳化联合人工晶状植入术治疗早期原发性闭角型青光眼的临床效果。方法选择仅局部用药即可控制眼压在正常范围内的早期闭角型青光眼合并白内障患者48例(54眼),应用周边虹膜切除术对28例(32眼)早期闭角型青光眼进行手术治疗,其结果与同类病人(20例22眼)的超声乳化联合人工晶状植入术治疗结果进行比较。术前,术后个月内每周次,半年内每月次,半年后三个月次做眼压、裂隙灯检查直至1年。比较者在术后眼压控制、视力恢复及前房情况,并作统计学分析。结果应用周边虹膜切除术治疗组术后平均眼内压为15.2±3.1mmHg,而同类病人经超声乳化联合人工晶状植入术治疗后平均眼内压为14.9±2.6mmHg。分别经周边虹膜切除术和超声乳化联合人工晶状植入术治疗,类病人眼内压在术后早期无明显差异(P〉0.05)。经超声乳化联合人工晶状植入术治疗,18眼(81.8%)最佳矫正视力提高,0.4者占63.6%,经周边虹膜切除术治疗术后最佳矫正视力无明显提高,其中8眼视力不增反降,最佳矫正视力0.4者占18.8%,者差异有显著性(P〈0.05)。经周边虹膜切除术治疗术后中央前房深度无明显变化,而经超声乳化联合人工晶状植入术治疗术后中央前房深度显著加深,者差异性明显(P〈0.05)。结论原发性闭角型青光眼早期患者施行超声乳化联合人工晶状植入术,术后房角显著加宽,中央前房深度显著加深,矫正视力也不同程度提高,且并发症少。
