“…In this study, the incidence of peripheral lesions (13.5%) was lower than in previous studies [12,13]. The difference rate was because we prioritized more peripheral retinal lesions----retinal holes/tears, peripheral lattice or pigmentary degeneration, vitreoretinal traction since those are considered risk factors for retinal detachment.…”

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.

“…These findings are consistent with those reported in past studies [ 17 – 19 ]. Employing eye steering techniques, changing patient positioning, and acquiring multiple images in a single imaging session may improve the success rate of high quality images in this patient population [ 20 – 23 ].…”

“…In difficult to image patient populations, UWF imaging was found to be a superior modality for viewing the posterior segment compared to clinical examination and standard fundus photography [ 24 ]. Previous studies have evaluated the sensitivity and specificity to detect retinal lesions using UWF imaging in various patient populations [ 22 , 23 , 25 , 26 ]. We did not evaluate the sensitivity and specificity of UWF imaging to dilated fundus examination or standard fundus photography in this study.…”

Background The ability to view the posterior segment in keratoprosthesis (Kpro) implanted patients is limited. The purpose of this retrospective, observational study was to investigate the use of ultra-wide field (UWF) scanning laser ophthalmoscopy imaging and its utility for serial evaluation of the retina and optic nerve in patients with either a Boston type I or II Kpro. Methods A retrospective chart review was performed for patients with a Boston type I or II Kpro seen at The Ohio State University Wexner Medical Center. Images were graded for quality by two masked observers on a defined four-point scale (“Poor”, “Fair”, “Good”, or “Very good”) and assessed for visible posterior segment anatomy. Interobserver agreement was described using the Kappa statistic coefficient (κ) with 95% confidence intervals. Results A total of 19 eyes from 17 patients were included in this study. Eighteen eyes had a type I Kpro, while one eye had a type II Kpro. UWF imaging from 41 patient visits were reviewed by two observers. Interobserver agreement between the two graders was fair for image quality (κ = 0.36), moderate for visibility of the macula with discernible details (κ = 0.59), moderate for visibility of the anterior retina with discernable details (κ = 0.60), and perfect agreement for visibility of the optic nerve with discernible details (κ = 1.0). In 6 eyes, UWF imaging was performed longitudinally (range 3–9 individual visits), allowing for long-term follow-up (range 3–46 months) of posterior segment clinical pathology. Conclusions UWF imaging provides adequate and reliable visualization of the posterior segment in Kpro implanted patients. This imaging modality allowed for noninvasive longitudinal monitoring of retinal and optic nerve disease in this selected patient population.

“…A recent study by Venkatesh et al . [ 23 ] noted that the reliability of the examination using Optos imaging for detecting peripheral lesions improved when the images were interpreted by a reader with prior retinal training. The tool is currently only good enough to detect the presence or absence of peripheral retinal lesions.…”

Some degenerations involving the peripheral retina can result in a rhegmatogenous retinal detachment. Currently, there are no clear guidelines for retinal screening and/or management of these peripheral retinal degenerations in patients with or without recent onset posterior vitreous detachment or in those prior to refractive surgery or intraocular procedures. This article aims to provide a set of recommendations for the screening and management of peripheral retinal degenerations based on a common consensus obtained from an expert panel of retinal specialists.
