Optomap ultrawide field imaging rapid screening peripheral retinal lesions before refractive surgery

Abstract

Purpose: The aim of this study was to assess the effectiveness of Optomap ultrawide field imaging for swiftly screening retinal lesions in individuals who have undergone refractive surgery. Methods: This retrospective study involved 400 eyes from 200 refractive surgery patients. All participants underwent post-dilated Optomap imaging and a 90D lens fundus examination conducted by a retinal specialist. The study focused on peripheral retinal lesions, including retinal holes/tears, peripheral lattice or pigmentary degeneration, and vitreoretinal traction, while excluding conditions like myopic conus, white without pressure, and snowflake degeneration. The 90D lens examination was established as the gold standard. Sensitivity and specificity of Optomap images were calculated and analyzed. The study compared the differences between the two screening methods for retinal lesions, utilizing the Chi-square test for statistical analysis. Results: Among the 400 eyes, the retinal specialist diagnosed peripheral retinal lesions in 54 eyes (13.5%) through dilated 90D examination and in 37 eyes (10.25%) through Optomap images. The difference between these two methods was not statistically significant (p=0.06). The overall sensitivity and specificity of the Optomap images were 75.9% and 95.31%, respectively. However, there were significant differences in the diagnosis of vitreous adhesion between the two methods (p=0.03). Conclusion: Optomap proves to be a convenient and effective tool for screening retinal lesions in refractive surgery patients. However, for cases involving peripheral vitreoretinal traction situated above or below the peripheral retina, a meticulous examination with the 90D lens fundus examination is recommended for comprehensive evaluation and accurate diagnosis.
