Clinical Utility of Ultra-Widefield Imaging with the Optos Optomap Compared with Indirect Ophthalmoscopy in the Setting of Non-Traumatic Rhegmatogenous Retinal Detachment.

Purpose: To evaluate the clinical utility of ultra-widefield imaging as an adjunctive tool in the diagnosis, management, and follow-up of eyes with non-traumatic rhegmatogenous retinal detachment.

Methods: Retrospective chart review of patients with a rhegmatogenous retinal detachment who received ultra-widefield imaging with the Optos® Optomap® P200Tx. Comparisons were made between UWF imaging and indirect ophthalmoscopy for features of detachments, including extent of detachment, holes, retinopexy, and related pathology.

Results: Thirty-six eyes of 34 patients were included. Preoperatively, ultra-widefield imaging more precisely documented the extent of retinal detachments in the superior, inferior, and nasal quadrants in 13.9% of cases. Ultra-widefield imaging failed to detect retinal holes in the superior and inferior quadrants in 11.1% and 19.4% of cases, respectively. In postoperative imaging, UWF photos did not detect retinopexy which was ophthalmoscopy-visible both superiorly and inferiorly in 19.4% of cases. The mean differences in clock hours of the detachments as documented on the clinical exam compared to ultra-widefield imaging in the superior, inferior, temporal, and nasal quadrants were -0.18 ± 0.84, 0.41 ± 1.16, 0.08 ± 1.08, and -0.13 ± 2.25 hours, respectively.

Conclusion: Ultra-widefield imaging is a useful adjunct for documentation of rhegmatogenous retinal detachments and their postoperative repair. However, detection of retinal holes, tears, and postoperative scarring is poor, especially in the inferior and superior periphery.
