Abstract

Purpose : To compare the sensitivities of orthogonal, peripheral steering, and auto-montaged images with ultra-widefield (UWF) imaging and the factors influencing the ability to identify retinal tears.

Methods : 376 treatment-naïve eyes (349 patients) that underwent laser retinopexy for retinal tears/holes between 2015-2021 with available pre-treatment UWF orthogonal, steering and auto-montage. Imaging were graded by trained photographers and reviewed by a retinologist who cross-referenced clinical scleral-depressed examination/drawings to determine whether images visualized all retinal tears/holes. Total retinal area visualized was divided by its optic disc area (pixels,MATLAB) to calculate relative retinal area (RRA). Sensitivities refer to true positive rates of identifying all retinal tears.

Results : 162 eyes (154) patients met inclusion criteria. Orthogonal, steering, and auto-montage images showed sensitvities of 47.5%, 90.7%, and 80.0%, respectively. Useable surface area increased from orthogonal versus montage by 34.7%+/-26.5%(mean+/-SD), which increased deetection of tears by 90.8%(p=0.006). By linear probability model, vertical meridian tears decreased probability of 26.6%, 86.2%, and 68.7%, respectively(all p<0.001), and horizontal meridian tears increased the probability by 62.2%, 92.9%, and 85.5%(all P<0.001). Posterior to the equator tears in orthogonal images increased the probability (91.4%,p<0.001). Artifacts such as lids/lashes, reflection, and faceguard decreased the probability in steering by 28.6%, 50.0%, and 66.7% respectively(p=0.020,p=0.049, and p=0.016).

Conclusions : Utilizing peripheral steering and auto-montage increases RRA and sensitivity of identifying peripheral retinal tears/holes. Tears in horizontal meridians or posterior to equator increase probability of identification. Common UWF imaging artifacts can significantly limit the probability of identifying retinal tears.
