Central and four gaze-steered UWF images.
Examples of the central image and four gaze-steered images (up, down, temporal, and nasal) taken during the UWF imaging examination.
Fig 2.
Four fundus quadrants and identification of retinal breaks.
We divided the fundus into the superior, inferior, temporal, and nasal quadrants, with the optic disc at the center. We then counted the retinal breaks (red circle) of the total fundus and the four quadrants.

Number of retinal breaks detected by indirect ophthalmoscopy and UWF imaging examinations by junior resident ophthalmologists.
For the indirect ophthalmoscopy examination, a total of 33 retinal breaks were detected in the 31 eyes. There were 5, 10, 11, and 7 retinal breaks detected in the superior, inferior, temporal, and nasal quadrants, respectively. For the UWF imaging, a total of 49 retinal breaks were detected in the 31 eyes, and there were 9, 13, 17, and 10 retinal breaks detected in the superior, inferior, temporal, and nasal quadrants, respectively. *P < .05, ** P < .01, ***P < .001, Fisher’s exact test.
Fig 4.
Number of retinal breaks detected by indirect ophthalmoscopy and UWF imaging examinations performed by senior resident ophthalmologists.
For the indirect ophthalmoscopy examination, a total of 22 retinal breaks were detected in the 22 eyes; there were 6, 2, 9, and 5 retinal breaks detected in the superior, inferior, temporal, and nasal quadrants, respectively. For the UWF imaging, a total of 27 retinal breaks were detected in the 22 eyes; there were 7, 3, 10, and 7 retinal breaks detected in the superior, inferior, temporal, and nasal quadrants, respectively.
