An Attachment Including a +20-D Lens to Gain Extended Field Images in Wide-Angle Optical Coherence Tomography Angiography
Purpose: This article evaluates the clinical usefulness of an attachment involving a +20-D lens to gain extended field images on wide-angle optical coherence tomography angiography (OCTA). Methods: 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 ...
