概括

在手术内光学连贯断层扫描 (OCT) 的指导下,精确的 suturing 显著加快角膜的解决方案和裂愈合在急性 edematous keratoconus 患者. 这种技术改善了随后的深层层状角膜整形和视觉敏度的结果.

科学领域:

眼科医生眼科眼科
角膜外科手术角膜外科手术
医疗成像医学成像

背景情况:

严重的急性 edematous keratoconus 在治疗中提出了挑战.
后方弹性层裂是这种情况的一个关键特征.
精确的手术修复对于视力恢复至关重要.

研究的目的:

评估后方弹性层裂的精确合的临床疗效,以手术内光学连贯断层扫描 (OCT) 为指导.
评估OCT指导接,前腔穿孔/排水和角膜热角膜整形术的综合方法,用于严重的急性 edematous keratoconus.
为了比较接组和对照组之间的视觉结果和角膜愈合.

主要方法:

一项非随机对照试验,涉及31名患有急性 edematous keratoconus 的患者.
研究组 (18名患者) 接受了OCT指导的精确 suturing,前腔穿刺/排水和角膜热角质造形术.
对照组 (13名患者) 没有进行 suturing; 应用标准治疗.

主要成果:

与对照组 (P<0.05) 相比,接组显示角膜胀的分辨率 (2.50天 vs. 7.00天) 和裂愈合 (7.50天 vs. 14.00天) 显著更快.
手术后的中角膜厚度在 suturing 组显著减少.
一年后的术后视力敏度在接组显著改善 (0.23±0.12对比0.33±0.11,P<0.05).

结论:

在OCT指导的精确合,与其他程序相结合,有效治疗严重的急性 edematous keratoconus.
这种技术迅速缓解角膜胀,促进裂愈合.
这种方法可以在随后的状角膜整形手术中改善视觉结果.

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
