Background: Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015 to December 2020. Methods: Patient historical factors, intraoperative/postoperative complications, and outcomes of IOL type (anterior chamber IOL versus scleral sutured IOL versus scleral fixated IOL versus. sulcus) were assessed. Primary outcomes were rates of postoperative retinal tears and rhegmatogenous retinal detachment. Secondary outcomes were rates of intraoperative endolaser, intraoperative retinal tear, and further IOL surgery. Results: The incidence of intraoperative retinal tears was 7.3% and not significantly different between techniques. Rates of intraoperative endolaser use were 17.5% among all techniques and not significantly different between techniques. Rates of postoperative retinal tear were low (0%–2.7%). Rates of postoperative rhegmatogenous retinal detachment were not significantly different between techniques (anterior chamber IOL 9/198 [4.5%], SFIOL 1/54 [1.9%], scleral sutured IOL 14/274 [5.1%], sulcus 2/35 [5.7%], total 26/561 [4.6%], P = 0.79). Rates of repeat IOL surgery trended higher in sulcus lenses (anterior chamber IOL 5/198 [2.5%], SFIOL 4/54 [7.4%], scleral sutured IOL 16/274 [5.8%], sulcus 5/35 [14.3%], total 30/561 [5.3%], P = 0.12). Conclusion: Intraoperative endolaser use and intraoperative retinal tear are not uncommon in secondary IOL surgery and underscore the importance of careful vitreoretinal management among these patients.

Purpose: To evaluate anatomic outcomes and surgeon response following the use of microserrated (Sharkskin, Alcon, Forth Worth, TX) internal limiting membrane (ILM) forceps compared with conventional (Grieshaber; Alcon) ILM forceps for peeling of the ILM. Methods: Patients were prospectively assigned in a 1:1 randomized fashion to undergo ILM peeling using microserrated forceps or conventional forceps. Rates of retinal hemorrhages, deep retinal grasps, ILM regrasping, time to ILM removal, and surgeon questionnaire comparing the use of microserrated and conventional ILM forceps were analyzed. Results: A total of 90 eyes of 90 patients were included in this study. The mean number of deep retinal grasps was higher in the conventional forceps group (1.51 ± 1.70 vs. 0.33 ± 0.56, respectively [P < 0.0001]). The mean number of failed ILM grasps was higher with conventional forceps (6.62 ± 3.51 vs. 5.18 ± 2.06 [P = 0.019]). Microserrated forceps provided more comfortability (lower number) in initiating the ILM flap (2.16 ± 0.85 vs. 1.56 ± 0.76, P < 0.001), comfortability in regrasping the ILM flap (2.51 ± 1.01 vs. 1.98 ± 0.89, P = 0.01), and comfortability in completing the ILM flap (2.42 ± 1.03 vs. 1.84 ± 1.02, P = 0.01). Conclusion: Surgeons utilizing the microserrated forceps experienced fewer deep retina grasps and fewer failed ILM grasps compared with conventional ILM forceps. The microserrated forceps was also a more favorable experience subjectively among the surgeons.

Purpose of review To highlight the recent work published from the Primary Retinal Detachment Outcomes (PRO) Study Group. Recent findings The PRO database was a large dataset made up of patients with primary rhegmatogenous retinal detachments (RRD) who had surgical repair during 2015. The database was constituted of nearly 3000 eyes from 6 centers across the United States and included 61 vitreoretinal surgeons. Nearly 250 metrics were collected for each patient, creating one of the richest datasets of patients with primary rhegmatogenous detachments and their outcomes. The importance of scleral buckling was demonstrated, particularly for phakic eyes, elderly patients, and those with inferior breaks. 360° laser may result in poorer outcomes. Cystoid macular edema was common, and risk factors were identified. We also found risk factors for vision loss in eyes presenting with good vision. A PRO Score was devised, to predict outcomes based on presenting clinical characteristics. We also identified characteristics of surgeons with the highest single surgery success rates. Overall, there were no major outcome differences between viewing systems, gauges, buckles sutured vs. scleral tunnels, drainage method, and techniques to address proliferative vitreoretinopathy. All incisional techniques were found to be very cost-effective treatment modalities. Summary Numerous studies resulted from the PRO database that significantly added to the literature regarding the repair of primary RRDs in the current era of vitreoretinal surgery.

Purpose: In this study, the authors aimed to identify the demographics of retinal detachment in children in the United States and to report the treatment modalities chosen by vitreoretinal surgeons and associated outcomes. Methods: This was a multicenter cohort analysis of the Vestrum Health LLC Database (Naperville, IL). Children (1–17 years) with rhegmatogenous retinal detachment, as identified by ICD10 and CPT codes, between January 2015 and August 2021 were enrolled. Demographic, comorbidity, visual acuity, and treatment modality data were analyzed. Results: A total of 168,152 RRDs were identified, of which 2,200 (1.3%) were aged 1 to 17 years. The mean age was 12.7 years, and 821 (37%) were women. The prevalence of rhegmatogenous retinal detachment increased with age (P = 0.009). Associated comorbidities included myopia (17.3%), ocular trauma (7.5%), and history of prematurity (5.7%). Laser retinopexy alone was used as the initial treatment modality in 19%, primary vitrectomy in 23%, primary scleral buckle in 25%, and vitrectomy with scleral buckle in 33%. The single surgery success rate for all procedures was 73.3%. Of the incisional surgical modalities, primary scleral buckling had the best single surgery success rate (79.0%) compared with vitrectomy alone (64.5%) and vitrectomy with scleral buckle (67.2%) (P < 0.001 and P = 0.004, respectively). Younger age resulted in worse SSSR overall (coefficient = 0.151, R2 = 0.746, P = 0.027). Conclusion: Rhegmatogenous retinal detachments in children increased with age. Myopia, trauma, and history of retinopathy of prematurity were common risk factors. Treatment techniques varied, but primary scleral buckling had the best anatomical and visual outcomes.

Purpose: Foveal herniation occurs when neuroretinal tissue protrudes through and above the level of an epiretinal membrane. This study describes the visual symptoms and spectral domain optical coherence tomography findings associated with foveal herniation and evaluates the postoperative visual, anatomical, and surgical outcomes. Methods: A multicenter retrospective review of patients diagnosed with epiretinal membrane identified 59 patients with preoperative foveal herniation on spectral domain optical coherence tomography. Data regarding visual symptoms, preoperative and postoperative best-corrected visual acuity (BCVA), central retinal thickness, macular volume, and size of foveal herniation were collected, and statistical analysis was performed. Results: A total of 58 of the 59 patients with foveal herniation underwent surgical epiretinal membrane peeling, with foveal contour restored in 53.5% of patients after surgery. Average BCVA improved from 20/80 to 20/40 Snellen equivalent at most-recent postoperative visit ( P < 0.0001). The average central retinal thickness decreased from 632 µ m to 432 µ m ( P < 0.0001) and the average macular volume decreased from 11.3 mm 3 to 9.5 mm 3 ( P < 0.0001) at 3 months postoperatively. Preoperatively, greater herniation height was associated with worse BCVA ( P = 0.008), greater central retinal thickness ( P = 0.01), retinoschisis, cystoid macular edema, foveolar detachment, ellipsoid zone abnormality, and external limiting membrane abnormalities ( P < 0.05). Postoperatively, there was a decrease in retinoschisis, cystoid macular edema, foveolar detachment, ellipsoid zone, and external limiting membrane abnormality ( P < 0.05) on spectral domain optical coherence tomography. Conclusion: Patients with larger foveal herniation height had greater preoperative central retinal thickness, worse preoperative and postoperative BCVA, and more intraretinal abnormalities on spectral domain optical coherence tomography. Surgical epiretinal membrane peeling in patients with foveal herniation resulted in a significant improvement in patients' BCVA and microstructural abnormalities.

Purpose: To characterize choroidal amyloid angiopathy (CAA) using late-phase indocyanine green angiography (ICGA). Methods: This was a multicenter retrospective observational case series on patients with transthyretin (ATTR) and AL amyloidosis who underwent ICGA. The timing of hyperfluorescence and longitudinal changes were analyzed. Results: Thirty-two patients (27 with ATTR and 5 with AL) with mean age of 58.9 ± 17.4 years were included. Hyperfluorescent spots in the very late phases of ICGA, corresponding to CAA, were observed in 49 of 55 eyes (89%). The median time to maximal staining was 672 (95% confidence interval, 644–752) seconds, which was significantly later than the initial staining (503 [95% confidence interval, 447–521], P < 0.0001; Wilcoxon signed rank test). In seven patients with ATTR amyloidosis who underwent follow-up of ICGA, the CAA was stable in two patients and improved in five patients during treatment. However, 3 patients (43%) had worsening vitreous opacities in both eyes, and 4 patients (57%) developed secondary open-angle glaucoma. Conclusion: Most patients with amyloidosis were found to have CAA on ICGA. Up to 12.5 minutes is required for maximal ICG staining. Choroidal amyloid angiopathy improved in most patients with systemic treatment and may serve as a marker of systemic disease status.
