To describe vitreoretinal imaging of eyes with vitreomacular abnormalities using high-resolution coronal-plane optical coherence tomography (OCT) scanning combined with simultaneous scanning laser ophthalmoscope (SLO) imaging.
A SLO-OCT (OTI, Canada) was used to scan 835 eyes in 736 patients with vitreomacular interface abnormalities including epiretinal membranes, macular hole, incomplete posterior vitreous detachment, vitreomacular traction syndromes and diabetic and cystoid macular oedema in a retrospective study. The longitudinal-B scan images and the transverse -C scan images in the coronal plane were used to describe vitreomacular interface abnormalities. The SLO-OCT simultaneously produces a confocal image of the retina.
The longitudinal "B" scan and en-face "C" scan images allowed identification of tractive forces of epiretinal membrane, contour of the hyaloid membrane and changes in inner retinal surface. A simultaneously obtained OCT scan and SLO image of the fundus offered exact co-localisation of retinal structures and vitreomacular interface abnormalities.
Scanning the vitreomacular interface by using combined OCT and SLO enables the visualisation and better understanding of various vitreomacular interface abnormalities, due to the ability to colocalise pathology on OCT with retinal vascular landmarks and the ability to visualise pathology from a new perspective, coronal plane parallel to retinal surface.
使用高分辨率冠状面光学相干断层扫描（OCT）联合同步扫描激光眼底镜（SLO）成像来描述患有玻璃体黄斑异常的眼睛的玻璃体视网膜成像。
在一项回顾性研究中，使用SLO-OCT（加拿大OTI公司）对736例患有玻璃体黄斑界面异常（包括视网膜前膜、黄斑裂孔、不完全性玻璃体后脱离、玻璃体黄斑牵引综合征以及糖尿病性和囊样黄斑水肿）的患者的835只眼睛进行扫描。利用冠状面的纵向B扫描图像和横向C扫描图像来描述玻璃体黄斑界面异常。SLO-OCT可同时生成视网膜的共焦图像。
纵向“B”扫描和正面“C”扫描图像能够识别视网膜前膜的牵引力、玻璃体膜的轮廓以及视网膜内表面的变化。同时获得的OCT扫描和眼底SLO图像可实现视网膜结构与玻璃体黄斑界面异常的精确共定位。
通过联合使用OCT和SLO扫描玻璃体黄斑界面，能够可视化并更好地理解各种玻璃体黄斑界面异常，这是因为它有能力将OCT上的病变与视网膜血管标志进行共定位，并且有能力从与视网膜表面平行的冠状面这一新视角来观察病变。
