视网膜脱离伴脉络膜脱离的临床分析

伴脉络膜脱离的视网膜脱离发病占同期视网膜脱离的４．１５％。分析住院手术１３５眼，总痊愈率为６５．９３％，与同期不含脉络膜脱离的视网膜脱离成功率相比，复位率低且有明显差异（Ｐ＜０．０１）。将１３５例脉络膜脱离分为花边、半月、球形三型，花边型组手术成功率较高。放视网膜下液有很高的意外率，封闭了裂孔，可以完成环扎术，不放水更有利。对注气要慎重。术前术后要早用、用足激素，同时尽早手术以提高成功率。

High Frequency Color Doppler Image of Choroidal Detachment

Purpose:To study the Color Doppler Image(CDI)characteristics of choroidal detachment and the applied valus of CDI.Methods:Seventy-two cases(74eyes)of choroidal edtachment were studied retrospectively.Results:The typical ultragraph of chororidal detachment displayed one or several smooth hemispherical or lobuler circular thick bands,with convex side toward vitreous cavity,Most of the choroidal detachments were located before the equator,a few of them were beyond the equator.CDI displayed blood flow singnal in the band.Pulse Doppler showed the frequency spectrum features of retinal detachment band were similar to those of central retinal vessels,whereas the frequency spectum features of choroidal detachment bend resembled those of ciliary artery in some cases of retinal detachment(RD)accompanied by choroidal detachment.Conclusion:CDI could make a correct and precise diagnosis of choroidal detachment.Eye Science2000;16:61-64.

OCTA技术在原发性青光眼中的应用研究进展

随着科学的发展和社会的进步,近年关于原发性青光眼眼底血流动力学的研究有了革命性的突破,诞生了一种非侵入性的影像学辅助检查方法—光学相干断层扫描血管成像技术(OCTA)。该技术与传统的检查方法相比具有很多优点,其利用分频谱振幅去相关血管成像(SSADA)的方式获取眼底三维立体血流图像,可以分层并量化眼底血流密度,具有无创、迅速、可重复、分层成像和高分辨率等特点,可用于监测青光眼眼底血流的早期改变、病情进展及疗效评估。但OCTA在临床实际应用中目前还存在一定的缺陷,需要进一步研究,才能更广泛地应用于青光眼疾病的更多领域,本文就OCTA技术在原发性青光眼中的应用及研究进展做一综述。
