Abstract: Objective: To study how to use the ultra-widefield scanning laser ophthalmoscope and the operator to move the position to perform fundus examinations on patients with an abnormal iris structure whose iris is incomplete and whose iris has other visual markers. Methods: In this case series study, twenty-nine patients (29 eyes), who underwent ultra-widefield scanning laser ophthalmoscopy in the First Affiliated Hospital of China Medical University from March 27, 2020 to August 11, 2020, were examined with the eye position adjustment method. Among the 29 cases, there were 8 cases (8 eyes) after trabeculectomy, 10 cases (10 eyes) after laser rhizotomy, 7 cases (7 eyes) after vitrectomy and 4 cases (4 eyes) with iris pigmented nevus. Results: After adjusting the eye position of the patients, so that the direction of the iris reconstruction structure is on one side of the examination surface, and the pupil is on the main body of the examination surface, fundus images were successfully acquired in all 29 patients (29 eyes) with abnormal iris. And the average number of quadrants of fundus images of all four diseases was 2.93, and the images reached the approximate wide-angle range (about 60°-100° fundus range), that can basically satisfy the needs of a clinical fundus examination. Conclusions: The method of adjusting the eye position by the operator can be used for ultra wide angle fundus examination of patients with abnormal iris structure, and the range of fundus image obtained is higher than that of ordinary fundus examination, which expands the scope of indications of orburg examination.
