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 center field to the area of the extended field with the attachment was calculated. Results: 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. Conclusions: The attachment involving the +20-D lens seems to be clinically useful to gain extended field images on wide-angle OCTA.
