Objectives

Narrative objectives1

Accurate scleral marking of retinal breaks is essential for successful scleral buckling. The aim of this study was to investigate if wide-field fundus images obtained with an Optos are useful for preoperative estimation of distance from limbus to retinal breaks.

Baseline Characteristics

Subjects
The subjects included patients whose fundus images that were taken with the method described in Image Acquisition allowed identification of retinal breaks, and who underwent explant scleral buckle surgery using silicone sponge primarily for rhegmatogenous retinal detachment, with anatomically successful repair between January 2016 and June 2017 at the Department of Ophthalmology, Kyushu University Hospital. Patients who required simultaneous cataract surgery and/or pars plana vitrectomy were excluded. The total number of eyes included for analysis was 29 eyes of 26 patients.

Outcome measures

In the wide-field fundus images obtained with the software, we determined the center of the disc and the center of the vortex vein ampulla located in the same quadrant as the retinal tears as described previously. In the preoperative fundus images, we measured distances from the fovea to the center of retinal tears (TM), to the center of the vortex vein ampulla (VM), and to the center of the optic disc (DM1). In the postoperative fundus images, we measured distances from the fovea to the center of optic disc (DM2). The average distance from the fovea to the posterior edge of scleral buckle (BM) was calculated by averaging the distances measured from the fovea to three different buckle edges. A representative image taken from case number 19 (Table 1) illustrates these distance measurements in the wide-field fundus images obtained with the Optomap auto-montage software
