UNASSIGNED: An attachment with a +20-D lens was developed to take OCTA images of anterior segments, and it was used to obtain extended field images of the posterior segment in this study. Ten eyes of 5 individuals who did not have a history of ocular or systemic disease underwent wide-angle OCTA with a 12 × 12-mm center field using the PLEX Elite 9000 with and without the attachment. The ratio of the area of the center field to the area of the extended field with the attachment was calculated.
UNASSIGNED: The mean area of the center image was 125 disc areas and that of the field extended by the attachment was 210 disc areas. The mean ratio between the center field and the extended field was 1.67.
UNASSIGNED: The attachment involving the +20-D lens seems to be clinically useful to gain extended field images on wide-angle OCTA.
■开发了带有20-D透镜的附件,以拍摄前段的OCTA图像,在这项研究中,它被用来获得后段的扩展场图像。5名没有眼部或全身性疾病史的人的10只眼睛使用PLEXElite9000进行了具有12×12-mm中心视野的广角OCTA,无论有无附件。计算中心场的面积与具有附件的扩展场的面积之比。
■中心图像的平均面积为125个圆盘区域,附件扩展的区域的平均面积为210个圆盘区域。中心场和扩展场之间的平均比率为1.67。
■涉及20-D镜头的附件似乎在临床上可用于在广角OCTA上获得扩展场图像。
