Clinical application of the ultra-widefield laser ophthalmoscope to the preoperative examination of patients with rhegmatogenous retinal detachment

Objective To compare the usefulness of the ultra-widefield laser ophthalmoscope(Daytona)and the three-mirror contact lens for detecting preoperative retinal breaks in a patient with rhegmatogenous retinal detachment, evaluate their consistency, and analyze their related factors. Methods One hundred and eleven eyes of patients with rhegmatogenous retinal detachment were retrospectively reviewed. Retinal images of the patients were obtained with the Optomap ultra-widefield laser ophthalmoscope imaging system and their fundi were examined with a three-mirror contact lens by ophthalmologists. All patients had undergone vitrectomy. The findings from the Optomap retinal images and the three-mirror contact lens examination were compared with the findings of the pars plana vitrectomy(PPV). Results The consistency of the two methods was moderate for detecting rhegmatogenous retinal detachment(Kappa=0.447). The number of different types of retinal holes detected by the two methods was different. The detection of the round hole demonstrated the most significant difference. Few other types of holes were missed for the two methods. Conclusion The ultra-wide-angle laser scanning ophthalmoscope fundus examination system is moderately consistent with the three-mirror contact lens for the preoperative examination of rhegmatogenous retinal detachment, and it may miss more peripheral retinal tears and macular holes, especially peripheral round retinal holes.
