To assess the utility of swept-source optical coherence tomography (SS-OCT) in visualizing macular hole (MH) closure through gas-filled eyes on postoperative day (POD) 1 using a dual scanning protocol.
We examined 30 consecutive patients with full-thickness MH who underwent standard vitrectomy with SF6 (25%) gas tamponade between July 2015 and April 2016. SS-OCT imaging was performed using horizontal raster and 16-line radial scans with manual delicate focusing to evaluate MH closure status.
On POD1, optically clear images with visualization of all retinal layers at the fovea were obtained in 80% of eyes, of which 71% achieved complete MH closure. Reasons for unsuccessful imaging included: hyphema (two eyes), dense cataract (two eyes), and gas meniscus interference (two eyes).
SS-OCT with dual scanning protocol and manual delicate focusing enabled consistent early visualization of foveal architecture for assessment of MH closure through gas-filled eyes. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:392-398.].
采用双扫描方案,评估扫频源光学相干断层扫描(SS-OCT)在术后第1天通过充气眼观察黄斑裂孔(MH)闭合情况的效用。
我们检查了2015年7月至2016年4月期间连续30例接受标准玻璃体切除术并使用25%六氟化硫(SF6)气体填塞的全层MH患者。使用水平光栅和16线径向扫描进行SS-OCT成像,并手动精细聚焦以评估MH闭合状态。
在术后第1天,80%的患眼中获得了在中央凹处所有视网膜层均清晰可见的图像,其中71%实现了MH完全闭合。成像失败的原因包括:前房积血(2只眼)、致密白内障(2只眼)和气体弯月面干扰(2只眼)。
采用双扫描方案和手动精细聚焦的SS-OCT能够在早期持续清晰显示中央凹结构,以评估充气眼中的MH闭合情况。[《眼科手术、激光与视网膜成像》。2017年;48:392 - 398。]
