Abstract
PURPOSE Evaluate preoperative bilateral eye patching (BEP) on subretinal fluid and vision in acute primary rhegmatogenous retinal detachments (RRDs). METHODS Retrospective nonrandomized interventional study of 335 patients with RRD undergoing BEP until surgery (BEP cohort) and separated by the percentage of full-time compliance: high (≥90%), medium (>90% but ≥50%), and low (<50%). Those declining BEP were included (control). All underwent surgery and were followed for ≥3 months. Imaging was obtained immediately before surgery. Best-corrected visual acuity was measured at the longest follow-up and immediately before surgery. SRF and foveal status immediately before surgery were analyzed. RESULTS Two hundred and forty and 95 patients were in BEP and control cohorts, respectively. Thirty patients presented immediately before surgery for analysis. High (64%) and medium (35%) compliance showed significantly greater ( P < 0.01) SRF reduction compared with low (4%) and control (3%). Mac-off RRD showed significantly greater ( P < 0.01) foveal reattachment with high (29%) and medium (8%) compliance compared with low (2%) and control (1%). Mac-on RRD demonstrated no significant differences ( P ≥ 0.51) in final best-corrected visual acuity among high (0 logarithm of the minimum angle of resolution [logMAR] [median], 20/20 Snellen), medium (0.10 logMAR, 20/25 Snellen), low (0.10 logMAR), and control cohorts (0.10 logMAR). Mac-off RRD demonstrated significantly better final best-corrected visual acuity with high compliance (0.30 logMAR, 20/40 Snellen) compared with low (0.40 logMAR, 20/50 Snellen; P = 0.04) and control (0.60 logMAR, 20/80 Snellen; P = 0.02). CONCLUSION Preoperative BEP can stabilize or improve subretinal fluid in acute primary RRD. Patients with BEP >50% of the time experienced the greatest benefits.

Abstract
BACKGROUND AND OBJECTIVE The objective was to evaluate factors associated with clinical presentation of uveal melanoma (UM) during the initial two years of the coronavirus disease 2019 pandemic. PATIENTS AND METHODS This was a multi-site, retrospective cohort study of patients treated for uveal melanoma during the first (early) and second (late) year of the pandemic compared with the year prior (control). RESULTS A total of 48, 67, and 75 patients were in the control, early, and late cohorts, respectively. The early cohort had a higher frequency of large tumors (control: 29.2%, early: 40.3%, late: 29.3%; P < 0.001) at presentation. Both the early and late cohorts had higher rates of enucleation (control: 8.33%, early: 20.9%, late: 18.67%; P ≤ 0.0338) compared to the control cohort. CONCLUSIONS While there was an increase in large tumors along with a rise in enucleation during the first year of the pandemic, enucleation rates remained elevated even while tumor sizes normalized.

Abstract
PURPOSE To evaluate prophylactic treatment (PTx) of lattice degeneration (LD) on retinal tear (RT) and rhegmatogenous retinal detachment (RRD) risk in fellow eyes of patients after primary RRD repair in the first eye. METHODS This was a consecutive case series with cohort control involving patients with RRD repair from January 1, 2013, through December 31, 2017. Patients received PTx (PTx cohort) or no PTx (No-PTx cohort) in fellow eye with 5-year follow-up. Primary outcome measure was proportion with new fellow eye RT/RRD. Secondary outcomes included logarithm of minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) and status of myopia, posterior vitreous detachment, and pseudophakia. RESULTS Four hundred ninety-eight patients were divided into 146 and 352 in PTx and No-PTx cohorts, respectively. PTx cohort developed significantly ( P < 0.05) fewer RT/RRD (17%) than No-PTx cohort (41%). PTx significantly ( P < 0.05) lowered RT/RRD irrespective of posterior vitreous detachment and myopia status. PTx patients undergoing phacoemulsification demonstrated significantly ( P < 0.05) less RT/RRD (22%) than No-PTx cohort (31%). There was no significant ( P = 0.96) final BCVA difference between PTx (median = 0 logMAR) and No-PTx (median = 0 logMAR) cohorts. CONCLUSION PTx of asymptomatic fellow eye LD reduced RT/RRD risk.

Abstract
INTRODUCTION The coronavirus pandemic created large shifts in utilization of hospital resources, patient presentations, and delivery of medical care. OBJECTIVES This retrospective study evaluated the ocular emergencies at a tertiary-care academic hospital in Wisconsin during the COVID-19-related "Safer at Home" order. METHODS Ophthalmology consultations performed March 23 through May 26, 2020, were compared to the same time period in the 4 preceding years and the subsequent year. Billing codes were obtained to evaluate the diagnoses and procedures performed during this time frame. RESULTS In 2020, 155 consultations were performed (42 emergency department, 113 inpatient), compared to a mean of 214 over the 5 other study years. The incidence rate ratio (IRR) of total consultations in 2020 was 0.72 (P ≤ 0.001) compared to previous years. Significantly fewer emergency department consultations were performed (IRR 0.62, P ≤ 0.001), while inpatient consultations were similar (IRR 0.88, P = 0.119). The most common diagnosis across all study years was fracture of the skull/orbit with injury to the eye/orbit. In 2020, 13% of consultations led to a procedure, compared to a total of 16% in the other years (IRR 0.59, P = 0.018). CONCLUSIONS This study demonstrated a 28% reduction in ophthalmology consultations at a major university hospital in Wisconsin during the COVID-19-related "Safer at Home" order, though the number of consultations leading to surgery were stable. This suggests that while patients with less acute needs may have deferred care, those requiring urgent surgery still presented to the emergency department. These data may help hospitals appropriately allocate eye care resources during future public health emergencies.

COVID-19 reduced scleral buckling training in fellows and shifted young ophthalmologists' preference toward vitrectomy: An Asia-Pacific survey. Clin Exp Ophthalmol 2023; 51:585-597.

Abstract
BACKGROUND To assess rhegmatogenous retinal detachment (RRD) surgery trends and training among young ophthalmologists (YOs, vitreoretinal fellows or attendings/consultants with ≤10 years of independent practice) and the impact of the COVID-19 pandemic. METHODS An anonymous online survey was completed by 117 YOs in the Asia-Pacific regarding their RRD surgery experiences in 2021-2022. RESULTS To achieve a 90% probability of surgical competency, 91 vitrectomy and 34 scleral buckling (SB) completions during fellowship were needed. In total, 49 (41.9%) YOs had fellowship affected by COVID-19. In the COVID versus pre-COVID era, however, the volume of SB completions per fellowship year decreased significantly (median [IQR] 3.3 [1.5, 9] vs. 13 [6.5, 23]; p < 0.001) and was lower than the required volume to achieve competency. YOs were less confident in conducting SB versus vitrectomy (3.5 ± 1.1 vs. 4.2 ± 0.8, p < 0.001), and they reported a decrease in the proportion of SB (-3.1%, p = 0.047) and an increase in the proportion of vitrectomy (+4.8%, p < 0.001) after the pandemic outbreak. Apart from RRD clinical characteristics, surgical confidence is among the main factors that affect surgical method decisions. During the pandemic, more YOs may have avoided SB due to the need for general anaesthesia, leading to longer surgical time and risk of viral transmission during intubation/extubation. CONCLUSIONS SB surgical exposure is suboptimal in most fellowship programs in the 11 Asia-Pacific countries/regions we surveyed and further declined during the COVID-19 pandemic. YOs are less confident in performing SB, leading to a trend toward primary vitrectomy since the COVID-19 outbreak.

Abstract
Purpose To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID-19 pandemic at a tertiary center in Taiwan. Methods Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan's first wave of domestic COVID-19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre-COVID year, 2019 (pre-COVID cohort, n = 121). Results The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single-surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487-8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720-0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ≤4 weeks but dropped to 83.3% in patients with duration >4 weeks. Conclusion During the COVID-19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons' decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.

Abstract
OBJECTIVE To evaluate the impact on trends in clinical presentation of acute, primary rhegmatogenous retinal detachments (RRD) from early to late phases of the COVID-19 pandemic. METHODS This study was a single-center, consecutive case series of 1,727 patients treated after vaccine availability ("late"; 3/29/21 to 9/26/21), corresponding time frame in previous year of pandemic ("early"; 3/30/20 to 9/27/20), and prior to pandemic ("pre"; 4/1/19 to 9/29/19). Primary outcome was proportion of patients presenting with macula-off RRD. Secondary outcomes included best-corrected visual acuity (BCVA) and primary proliferative vitreoretinopathy (PVR). RESULTS While macula-off RRD rates were significantly (P < 0.0001) elevated in early and late cohorts compared to the pre cohort, only the early cohort showed a significant (P < 0.0001) increase in both primary PVR presentation and complex RRD repair. Patients lost to follow-up in early cohort were significantly (P < 0.0001) higher than others. Early cohort showed significantly (P < 0.0001) worse final BCVA compared to others. CONCLUSION Patients in late pandemic were less likely to exhibit clinical features of worse RRD disease and have improved visual outcomes compared to those in early pandemic.

Abstract
BACKGROUND Proliferative vitreoretinopathy (PVR) is a blind-causing disease initiated by the activation of retinal pigmented epithelium (RPE) primarily induced by TGF-β families. Migrasome is a recently discovered type of extracellular vesicle related to cell migration. RESULTS Here, we used ex vivo, in vitro, and in vivo models, to investigate the characteristics and functions of migrasomes in RPE activation and PVR development. Results indicated that the migrasome marker tetraspanin-4 (TSPAN4) was abundantly expressed in human PVR-associated clinical samples. The ex vivo model PVR microenvironment is simulated by incubating brown Norway rat RPE eyecups with TGF-β1. Electron microscope images showed the formation of migrasome-like vesicles during the activation of RPE. Further studies indicated TGF-β1 increased the expression of TSPAN4 which results in migrasome production. Migrasomes can be internalized by RPE and increase the migration and proliferation ability of RPE. Moreover, TSPAN4-inhibited RPE cells are with reduced ability of initiating experimental PVR. Mechanically, TSPAN4 expression and migrasome production are induced through TGF-β1/Smad2/3 signaling pathway. CONCLUSION In conclusion, migrasomes can be produced by RPE under PVR microenvironment. Migrasomes play a pivotal role in RPE activation and PVR progression. Thus, targeting TSPAN4 or blocking migrasome formation might be a new therapeutic method against PVR.

Abstract
INTRODUCTION COVID-19 has had a tremendous impact on our everyday life. A growing body of evidence indicates that subsequent lockdowns and fear of exposure may have impacted patient care. We analyzed data on incidence and time to surgery in cases of rhegmatogenous retinal detachments (RRD) at three defined time points before, during, and 1 year after the first lockdown period in Germany. METHODS In this single-center study, we identified all patients who were admitted and treated for a primary RRD in April and May 2020, the time of the first lockdown period in Germany, and compared them with cases of the same time period in the years 2019 and 2021. The time from first occurrence of symptoms to surgery as well as visual outcome was analyzed. RESULTS A total of 192 patients presented to our tertiary academic referral center with a RRD during the months of April and May in 2019 (72 patients), 2020 (62 patients), and 2021 (58 patients) and were included in this study. There were no significant differences with regard to gender and age. In 2019, the time interval between occurrence and presentation to our hospital amounted to a mean of 5.96 days and in 2021 to mean of 5.45 days. However, in 2020, the time between occurrence and presentation was significantly longer with a mean of 15.36 days. The number of patients presenting with a macula-on retinal detachment was also lowest in 2020 (39.2%) compared to 2019 (50.7%) and 2021 (50.0%). Furthermore, with 1.24 logMAR the mean BCVA upon initial presentation was lower in 2020 compared to 0.93 logMAR in 2019 and 1.06 logMAR in 2021. Six to twelve weeks following surgery, visual acuity had improved in 56.1% of patients in 2019 and 60.0% of patients in 2021 as compared to 59.0% in 2020. CONCLUSION We found significant differences in terms of elapsed time from first symptoms to surgical management for patients in 2020 in comparison with the same time period in 2019 and 2021. Less strict lockdown policies appear to impact patient behavior and patient care. Further measures, such as questionnaires, might help address which measures may provide safer circumstances for patients to consult health care providers in the case of future strict lockdowns.

Treatment and prevention of pathological mitochondrial dysfunction in retinal degeneration and in photoreceptor injury. Biochem Pharmacol 2022; 203:115168. [PMID: 35835206 DOI: 10.1016/j.bcp.2022.115168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 07/05/2022] [Accepted: 07/06/2022] [Indexed: 11/19/2022]
Abstract
Pathological deterioration of mitochondrial function is increasingly linked with multiple degenerative illnesses as a mediator of a wide range of neurologic and age-related chronic diseases, including those of genetic origin. Several of these diseases are rare, typically defined in the United States as an illness affecting fewer than 200,000 people in the U.S. population, or about one in 1600 individuals. Vision impairment due to mitochondrial dysfunction in the eye is a prominent feature evident in numerous primary mitochondrial diseases and is common to the pathophysiology of many of the familiar ophthalmic disorders, including age-related macular degeneration, diabetic retinopathy, glaucoma and retinopathy of prematurity - a collection of syndromes, diseases and disorders with significant unmet medical needs. Focusing on metabolic mitochondrial pathway mechanisms, including the possible roles of cuproptosis and ferroptosis in retinal mitochondrial dysfunction, we shed light on the potential of α-lipoyl-L-carnitine in treating eye diseases. α-Lipoyl-L-carnitine is a bioavailable mitochondria-targeting lipoic acid prodrug that has shown potential in protecting against retinal degeneration and photoreceptor cell loss in ophthalmic indications.

Am J Ophthalmol 2022; 242:7-17. [PMID: 35609676 PMCID: PMC9122843 DOI: 10.1016/j.ajo.2022.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 05/13/2022] [Accepted: 05/13/2022] [Indexed: 12/01/2022]
Abstract
PURPOSE Evaluate factors associated with coronavirus 2019 (COVID-19) vaccine hesitancy and clinical trends in primary rhegmatogenous retinal detachments (RRDs) during the first year of vaccine availability. DESIGN Single-center, clinical cohort study. METHODS Consecutive patients from December 14, 2020, to December 12, 2021, presenting vaccinated (Prior-), subsequently vaccinated (Later-), or remaining unvaccinated (Never-Vax). Primary outcome was proportion with macula-off (mac-off) RRD. Secondary outcomes included logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), primary proliferative vitreoretinopathy (PVR), proportion lost to follow-up, and distance traveled. RESULTS 1047 patients were divided into 391 Prior-, 252 Later-, and 404 Never-Vax cohorts. Significantly greater proportions of Later- and Never-Vax cohorts presented with mac-off RRDs (Prior-Vax = 44.5%; Later-Vax = 54%, P < .0001; Never-Vax = 57.9%, P < .0001) and primary PVR (Prior-Vax = 4.3%; Later-Vax = 13.6%, P < .0001; Never-Vax = 17.1%, P < .0001) compared to Prior-Vax cohort. Significantly greater proportion of Never-Vax cohort (7.7%, P < .0001) were lost to follow-up compared to Prior- (2.3%) and Later-Vax (2.2%) cohorts. Never-Vax cohort (median = 35 miles) traveled farther compared to Prior- (median = 22.3 miles; P < .0001) and Later-Vax cohorts (25.45 miles; P = .0038). Prior-Vax cohort had significantly better (P < .05) initial (median = 0.30 logMAR) and final (0.18 logMAR) BCVA compared to Later- (Initial: 0.54 logMAR; Final: 0.30 logMAR) and Never-Vax (Initial: 0.70 logMAR; Final: 0.40 logMAR) cohorts. CONCLUSIONS COVID-19 vaccine hesitancy is associated with worse clinical presentation and outcomes for primary RRD.
