Abstract
To present a case of nasal vein occlusion that has not been reported after the coronavirus disease 2019 (Covid-19) pandemic. A 53-year-old patient reported a complaint of floaters after a recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. His best corrected visual acuity (BCVA) was 20/20 for both the eyes. On examination, a flame-shaped hemorrhage was observed in the left eye around the infero-nasal area adjacent to the optic disc. Temporal branch vein occlusion has been widely reported in association with SARS-CoV-2 infection. We emphasize that nasal vein occlusions triggered by Covid-19, which do not cause vision loss, should also be considered.

Complete Blood Count-Derived Inflammation Indices and Retinal Vein Occlusion: A Case-Control Study. Ophthalmol Ther 2022; 11:1241-1249. [PMID: 35503164 PMCID: PMC9114275 DOI: 10.1007/s40123-022-00511-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 04/08/2022] [Indexed: 11/26/2022] Open
Abstract
Introduction This study evaluated complete blood count-derived inflammation indices in patients with retinal vein occlusion (RVO). Methods Participants in this case–control study were 54 patients with RVO and 54 age- and sex-matched control subjects. All participants underwent a thorough ophthalmic examination, as well as blood sample testing for complete blood count. Comparison of all parameters derived from complete blood count as well as calculation of specific indices was performed between patients with RVO and controls. Results Patients with RVO presented significantly higher white blood cell count (p = 0.033), neutrophil count (p = 0.003), neutrophil-to-lymphocyte ratio (NLR, p = 0.002), red cell distribution width (RDW, p = 0.009), mean platelet volume (MPV, p = 0.023), and systemic immune-inflammatory index (SII, p = 0.007) compared to controls. Receiver operator characteristic curve (ROC) analysis showed that NLR was superior to other inflammatory indices, having the greatest area under the curve. The optimal cutoff value for NLR to predict RVO was 2.29 with 46.2% sensitivity and 77.8% specificity. Conclusion Patients with RVO presented increased NLR, RDW, MPV, and SII, providing evidence that inflammation plays an important role in the pathogenesis of RVO. Complete blood cell count-derived indices can be easily calculated and may serve as an easy, simple, and cost-effective tool to evaluate the degree of systemic inflammation in patients with RVO, so as to potentially guide treatment.

Abstract
This prospective comparative case series aims to compare best-corrected visual acuity (BCVA), retinal microvasculature, and retinal structural changes in patients treated with either ranibizumab or aflibercept for macular edema (ME) secondary to treatment-naïve branch retinal vein occlusion (BRVO) by optical coherence tomography angiography (OCTA). Ten patients were enrolled with macular capillary density of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) and foveal avascular zone (FAZ) measured in both eyes before and after treatment. Final central retinal thickness and BCVA improved significantly (p < 0.05), and densities of SCP and DCP of BRVO sectors were significantly lower at baseline than fellow eye counterparts and remained persistently lower during treatment, particularly in the aflibercept group (p < 0.05). SCP density, DCP density of both BRVO sectors (p = 0.0001, p < 0.0001), and non-BRVO sectors (p < 0.0001, p < 0.0001) were significantly correlated with final BCVA for diseased eyes. Using multivariate general linear model analysis, and including OCTA parameters only, but not all of the available clinical data, DCP density of BRVO sectors in both eyes was the most predictive factor for final visual outcome (probability p < 0.0001). OCTA offered further qualitative and quantitative evaluation of treatment-naïve BRVO. Judging by OCTA parameters, not only in the diseased eye but also in the fellow eye, DCP density of BRVO sectors was the most predictive factor of final visual outcome.

Abstract
Purpose The purpose of this review article is to provide a comprehensive review of the current applications of intravitreal DEX implant (Ozurdex®, Allergan Inc, Irvine, CA) for a variety of ophthalmic conditions – ranging from FDA approved indications to off-label uses. We have attempted to provide relevant evidence from the literature to help a reader develop an understanding of the biological and pharmacokinetic properties of DEX implant, its uses, and potential side effects. Methods PubMed searches were performed using the terms “Ozurdex”, or “intravitreal DEX implant”, AND “retinal vein occlusion”, or “diabetic macular edema”, or “uveitis”. The search was performed in July of 2021, with an additional search in October 2021. All original English language articles were considered for this review. Results DEX implant has evidence of efficacy in a variety of clinical situations including macular edema associated with retinal vein occlusion, diabetes, uveitis, and others. Safety concerns include cataract formation and progression, intraocular pressure elevation, complications related to intravitreal injection, and opportunistic infections secondary to steroid-induced immune suppression. Conclusion DEX implant is a useful tool in the management of several retinal disorders. Further studies are needed for head-to-head comparison with other treatment modalities and to determine its precise place in clinical practice.

Abstract
PURPOSE retinal vein occlusion (RVO) is classified as either branch (BRVO) or central (CRVO) RVO. The gold standard treatment for macular oedema (MO) secondary to RVO is intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. Our study aimed to compare ranibizumab and aflibercept outcomes over a maximum follow-up of five years. METHODS this retrospective study assessed treatment-naïve RVO patients. Active disease was treated with three loading injections followed by a pro-re-nata (PRN) regimen of an anti-VEGF agent. Visual outcomes and injection frequency were analyzed, with patients stratified according to RVO subtype, anti-VEGF agent used, baseline vision, and age. RESULTS 316 CRVO-affected eyes and 467 BRVO-affected eyes were analysed. Visual benefits between different treatments did not significantly differ, except in year 1 in ranibizumab-treated BRVO eyes. However, aflibercept-treated CRVO and BRVO eyes required significantly fewer injections during the follow up period. Furthermore, our results confirm that younger patients achieve better visual outcomes with fewer intravitreal injections. Overall, half of our patients did not require further injections after 1 year from diagnosis. CONCLUSION the results demonstrate that anti-VEGF treatment of RVO benefits vision for up to 5 years. Our findings are the first to suggest that compared to ranibizumab, fewer aflibercept injections may be required over five years follow up. Prospective randomised trials are needed to confirm this, alongside further attention to OCT scan features and the effect of patient demographics on treatment outcomes.

Abstract
Background To investigate microstructural alterations of white matter in retinal vein occlusion (RVO) patients by tract-based spatial statistics (TBSS) and diffusion tensor imaging (DTI). Material/Methods. DTI was performed on 14 RVO patients and 14 normal controls (HCs). We measured and recorded fractional anisotropy (FA) and radial diffusivity (RD) of white matter fibers and classified them through the receiver operating characteristic (ROC) curve and correlation analysis, respectively. Results The mean FA value of white matter in RVO patients is lower than the HCs, and the mean RD value in RVO patients increased, especially in the bilateral posterior thalamic, bilateral sagittal stratum, body of corpus callosum, cingulum, and fornix. The ROC curve of different brain regions showed high accuracy. Moreover, the mean FA and RD values were significantly correlated with visual and psychological disorders. Conclusion TBSS could be regarded as an important method to reveal the alterations of white matter in RVO patients, indicating the underlying neurological mechanism of the RVO.

Abstract
OBJECTIVE OR PURPOSE Branch retinal vein occlusion (BRVO) causes macular edema (ME) that can be controlled with anti-vascular endothelial growth factor (VEGF) treatments. However, these treatments are not curative, necessitating additional anti-VEGF treatments at recurrences. Long-term results, optimal anti-VEGF treatment regimens, and the comprehensive effects of ME recurrences are largely unknown. Thus, we aimed to examine the effects of foveal thickness (FT) fluctuation (FTF) on visual and morphologic outcomes following anti-VEGF treatments for BRVO-ME administered via a pro re nata regimen. DESIGN A retrospective, observational case series SUBJECTS, PARTICIPANTS AND/OR CONTROLS: This study analyzed 309 treatment-naïve patients (309 eyes) with BRVO-ME between 2012 and 2021 at a multi-center retinal practice. METHODS, INTERVENTION, OR TESTING FT was assessed via optical coherence tomography (OCT) at each study visit. MAIN OUTCOME MEASURES We evaluated the logarithm of the minimal angle of resolution best corrected visual acuity (logMAR BCVA) and the defect length of the foveal ellipsoid zone (EZ) band measured via OCT. RESULTS At baseline, the mean logMAR BCVA was 0.30±0.30 and the mean FT was 503±162 μm. The number of anti-VEGF injections for BRVO-ME was 5.8±4.6 during the mean follow-up period (50.6±22.2 months). At the final examination, the mean logMAR BCVA and FT values were significantly improved compared with the baseline. Multiple regression analyses showed that age, baseline logMAR BCVA, and FTF were significantly associated with the final logMAR BCVA (β=0.20, 0.35, and 0.30, respectively). FTF (divided into Groups 0-3 in ascending order of FTF) was significantly associated with the logMAR BCVA and the defect length of the foveal EZ band at the final examination. The defect lengths of the foveal EZ band were longitudinally shortened in Groups 0-1 and were slightly prolonged in Groups 2-3. The logMAR BCVA maintained improvements in Groups 0-1, and worsened slightly in Groups 2-3. CONCLUSIONS FTF was significantly associated with visual acuity and foveal photoreceptor status. Thus, may improve the morphologic and functional prognoses of eyes with BRVO by identifying the characteristics of eyes with a larger FTF, and consequently controlling the FTF more strictly.

Abstract
Eye diseases are an important group of increasingly prevalent disorders that contribute very significantly to disability and represent a considerable health burden. Some data suggest that several of these diseases may be associated with sleep-disordered breathing, mainly obstructive sleep apnea (OSA), due to intermediate mechanisms, such as intermittent hypoxia or sleep fragmentation. The aims of this systematic review were to identify and critically evaluate the current evidence supporting the existence of a possible relationship between OSA and the more relevant eye diseases as well as to evaluate the potential pathogenic mechanisms. There is a body of largely low-level evidence for the association of OSA with glaucoma, nonarteritic ischemic optic neuropathy, central serous chorioretinopathy, and diabetic retinopathy. Meta-analysis of available case-control studies shows that OSA increases the risk of glaucoma (pooled odds ratio: 1.50; 95% confidence interval: 1.25 to 1.80; P < .001), nonarteritic ischemic optic neuropathy (3.62; 1.94 to 6.76; P < .001), and diabetic retinopathy (1.57; 1.09 to 2.27; P = .02). Moreover, several pathogenic pathways have been identified, mainly related to hypoxic damage, mechanical stress, systemic inflammation, oxidative stress, sympathetic tone, and endothelial dysfunction. In contrast, information about the effect of apnea-hypopnea suppression on the development and progression of eye damage is either nonexistent or of a very low level of evidence. In conclusion, OSA has emerged as an additional potential risk factor for many eye diseases, although their link is weak and contradictory, so further examination is required.

Abstract
RATIONALE Retinal vein occlusion (RVO) is the second commonest retinal vascular pathology, with macular edema (ME) as one of its major complications, which could finally cause vision loss. Anti-vascular endothelial growth factor (anti-VEGF therapy), as the standard therapy, has an unsustainable effect and needs repeated injections, which associates with frequent adverse events and significant economic burden. We reported a patient who had developed RVO and ME, and finally recovered after electroacupuncture treatment. PATIENT CONCERNS A 56-year-old woman complained a decrease of visual acuity in the right eye for 1 year. She received injection of 0.5 mg Conbercept, one of the anti-VEGF therapies, in the vitreous cavity 6 times in 1 year, and finally turned to acupuncture for help out of short-term effectiveness after each injection and high expenditure (CNY 40,800). No other severe medical history was reported. DIAGNOSIS Under comprehensive consideration of clinical manifestations and the results of fluorescein fundus angiography and optical coherence tomography, the patient was diagnosed with hemi-RVO and ME. INTERVENTIONS The patient received electroacupuncture 3 sessions per week throughout 8 months (93 sessions in total). OUTCOMES The visual acuity of the patient was improved from 0.6 to 0.9 after the 8-month electroacupuncture treatment and remained stable during the 24-month follow-up; the central retinal thickness remained stable between 350 and 414 throughout the treatment and follow-up periods. Patients regarded the vision-related quality of life as satisfactory. The total expenditure of electroacupuncture treatment was CNY 6045. The patient did not receive any Conbercept injection over the whole period of 32 months. No relevant adverse events occurred. LESSONS Electroacupuncture might be effective in alleviating the symptoms of hemi-RVO-associated ME, with a potential of long-lasting effect. The frequency of anti-VEGF therapy could be reduced to the most extent, and the possibility of recurrence could be reduced as well, resulting good economic benefits.

Sacconi R, Simona F, Forte P, Querques G. Retinal Vein Occlusion Following Two Doses of mRNA-1237 (Moderna) Immunization for SARS-Cov-2: A Case Report. Ophthalmol Ther 2021; 11:453-458. [PMID: 34881416 PMCID: PMC8654602 DOI: 10.1007/s40123-021-00441-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Accepted: 11/26/2021] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Published data on possible ocular adverse events potentially associated with vaccination with the SARS-Cov-2 mRNA-1237 vaccine are scarce. In this report, we describe the case of a patient who had a hemispheric retinal vein occlusion potentially associated with being vaccinated with the second dose of the SARS-Cov-2 mRNA-1237 vaccine. METHODS Case report including a discussion on multimodal imaging. RESULTS A 74-year-old woman presented with painless vision loss in the right eye experienced 48 hours after receiving a second dose of the mRNA-1237 vaccine. The patient was receiving oral anticoagulant therapy for atrial fibrillation. Her best-corrected visual acuity (VA) was 20/32, and fundus examination showed venous congestion and widespread blot haemorrhages in the inferior quadrants. Based on multimodal imaging evaluation, the diagnosis of hemispheric retinal vein occlusion was made. Due to the development of cystoid macular oedema with intraretinal fluid and the decline in VA, the patient was treated with two injections of intravitreal ranibizumab, leading to functional improvement and regression of oedema. CONCLUSIONS We report a case with retinal vein occlusion 48 hours after vaccination with the SARS-Cov-2 mRNA-1237 vaccine; however, the relationship between these two events remains unclear. Further research is warranted to better understand the potential link between retinal thrombotic events and vaccination.

Abstract
PURPOSE To describe the posterior ophthalmic manifestations of catastrophic antiphospholipid syndrome. METHODS Retrospective case series of patients presenting with catastrophic antiphospholipid syndrome and posterior segment ocular manifestations. The main outcomes were the type of posterior segment manifestations at catastrophic antiphospholipid syndrome diagnosis, specifically retinal vascular occlusion, vasculitis, or choroidopathy, and the final best-corrected visual acuity. RESULTS This study included 23 patients (11 cases treated by the authors and 12 published case reports); 21 (91%) of them female. Their median age at diagnosis was 28 years (range, 16-79 years). Ophthalmologic manifestations were usually bilateral (n = 19, 83%) and involved vascular occlusive retinopathy (n = 17, 74%), choroidopathy (n = 11, 48%), or retinal vasculitis (n = 1, 4%). Final best-corrected visual acuity was not significantly worse than the best-corrected visual acuity at diagnosis (P = 0.16). Retinal vascular occlusions were associated with poorer final visual acuity than choroidopathy (P = 0.002). After a median follow-up of 14 months (range, 2-132 months), nearly half the patients (n = 11, 48%) had permanent vision loss including best-corrected visual acuity of <20/400 for 4 patients. CONCLUSION Posterior ophthalmic manifestations of catastrophic antiphospholipid syndrome were mainly bilateral retinal vascular occlusion, which had the worst visual prognosis, followed by choroidopathy and retinal vasculitis. Permanent visual loss was common.

Association between capillary congestion and macular edema recurrence in chronic branch retinal vein occlusion through quantitative analysis of OCT angiography. Sci Rep 2021; 11:19886. [PMID: 34615979 PMCID: PMC8494742 DOI: 10.1038/s41598-021-99429-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 09/24/2021] [Indexed: 11/14/2022] Open
Abstract
This study aims to quantitatively investigate the optical coherence tomographic angiography (OCTA) findings of capillary congestion and its association with macular edema (ME) recurrence in chronic branch retinal vein occlusion (BRVO). We retrospectively reviewed the medical records of 115 consecutive patients with major ischemic BRVO who reached stable macula (without ME for two consecutive visits) at baseline (the first visit within the stable period). All patients were classified into a recurrence or non-recurrence groups depending on ME recurrence. Capillary congestion of deep capillary plexuses (DCP-C) and other abnormal capillary lesions were segmented, and their areas, vascular densities, and mean retinal thicknesses (MRT) were calculated. The main outcomes were differences between the two groups and risk factors for recurrence among baseline and OCTA parameters. A total of 76 eyes were included, of which 22 (28.9%) recurred. DCP-C existed in all eyes at baseline. MRT of DCP-C (p = 0.006) was greater in the recurrence group. Greater MRT of DCP-C (OR: 1.044; p = 0.002) and more frequent intravitreal injections (OR: 1.803; p < 0.001) were associated with a higher risk of relapsing ME. DCP-C may contribute to the anatomical stability of chronic BRVO and simultaneously be the source of ME.

Abstract
This study evaluated longitudinal changes in peripapillary retinal nerve fiber layer (pRNFL) thickness in eyes affected with branch and central retinal vein occlusion (BRVO and CRVO, respectively) and fellow eyes. This retrospective case-control study included patients with newly diagnosed unilateral BRVO (46 patients) or unilateral CRVO (27 patients). The control group included 48 patients without abnormal findings on the fundus examination. Global and all-sector pRNFL thicknesses were greater in eyes with BRVO and CRVO than in fellow eyes at baseline; however, at 24 months, this difference remained only in the temporal sector of eyes affected with CRVO. Although the global pRNFL thicknesses of the fellow eyes in the BRVO and CRVO groups decreased significantly at 24 months compared to baseline (p = 0.001 and p = 0.011, respectively), there was no significant difference in the normal control group (p = 0.824). The global, inferior temporal, and inferior nasal pRNFL thicknesses at 12 and 24 months were significantly lower in the fellow eyes of the CRVO group than in those of the BRVO and normal control groups. The fellow eyes of patients with BRVO and CRVO suffered a significant reduction in pRNFL thickness compared to normal controls, indicating that they are susceptible to pRNFL damage.

ASSOCIATIONS WITH RECURRENCE OF MACULAR EDEMA IN BRANCH RETINAL VEIN OCCLUSION AFTER THE DISCONTINUATION OF ANTI VASCULAR ENDOTHELIAL GROWTH FACTOR. Retina 2021; 41:1892-1900.

Abstract
PURPOSE To identify factors predicting the recurrence of macular edema after the discontinuation of intravitreal antivascular endothelial growth factor injection in patients with branch retinal vein occlusion. METHODS This retrospective study included only subjects who had discontinued injections at 3 months after the final bevacizumab injection due to fully resolved macular edema. Fifty-two eyes meeting the criteria were included in the study and divided into two groups (recurrence and no recurrence). Clinical features and measurements of retinal thickness at the time of the diagnosis and when the decision to stop injections was made (stopping point) were analyzed. RESULTS At the stopping point, the no recurrence group showed a thinner parafoveal inner retina, better best-corrected visual acuity, and lower incidence of ellipsoid zone disruption in multivariate logistic regression analysis (all P < 0.05). Similarly, parafoveal inner retinal thinning of more than 30 µm, when compared with the corresponding region of the fellow eye or the unaffected region of the affected eye, was significantly related to less recurrence of macular edema. CONCLUSION Thinning of the parafoveal inner retina as well as better vision and intact outer retinal layers are associated with a lack of recurrence of macular edema. These findings suggest that inner retinal atrophy after branch retinal vein occlusion may result in a reduction in oxygen demand in the affected retinal tissue and less production of vascular endothelial growth factor.

Abstract
Purpose: This work aims to investigate real-world treatment patterns and outcomes in eyes with branch retinal vein occlusion in the antivascular endothelial growth factor (anti-VEGF) era. Methods: A retrospective, nonrandomized, comparative study was conducted on eyes diagnosed with branch retinal vein occlusion at a single tertiary center between 2009 and 2017. Medical history, treatment patterns, and visual acuity outcomes were examined. Subanalysis was performed for eyes that met the eligibility criteria for the BRAVO (Ranibizumab for the Treatment of Macular Edema Following Branch Retinal Vein Occlusion) trial. Results: A total of 315 eyes were included, of which 244 were treatment naive. In all eyes, the most common first treatment was the following: intravitreal bevacizumab (38.4%), aflibercept (15.1%), ranibizumab (8.1%), sectoral scatter laser (6.2%), and triamcinolone (3.1%). At 1 year, treatment-naive eyes had received an average of 2.43 anti-VEGF injections. During follow-up, treatment-naive eyes gained an average of 0.21 Early Treatment Diabetic Retinopathy Study lines. Forty eyes that met BRAVO trial criteria received an average of 5.05 anti-VEGF injections in the first year and gained an average of 1.83 Early Treatment Diabetic Retinopathy Study lines. Conclusions: This real-world cohort received fewer anti-VEGF injections at year 1 and experienced less improvement in visual acuity during the course of treatment than clinical trial participants. Trial-eligible patients received more injections and had greater visual gains than those who would not have been eligible for the trial.

Abstract
PURPOSES To quantitatively evaluate the vessel density of macular microvasculature, choriocapillary, and foveal avascular zone (FAZ) in both eyes of patients with unilateral retinal vein occlusion (RVO) using the optical coherence tomography angiography (OCTA) compared with the normal controls. METHODS A retrospective review was conducted on 72 patients with unilateral RVO (72 eyes with RVO and 72 RVO fellow eyes) and 72 healthy individuals (72 normal control eyes). The 3 × 3 mm macular angiogram was acquired using the OCTA. The vessel densities of the retinal superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillary plexus (CCP) were measured, and FAZ was quantified. RESULTS The RVO eyes compared to their fellow eyes, and the fellow eyes compared to the normal controls, showed a significantly lower vessel density in both the SCP and DCP in the whole image and parafovea (P < 0.05) and the CCP (P < 0.05), except for the foveal region (P > 0.05). No significant differences between the RVO eyes and the fellow eyes in the FAZ area and perimeter (P > 0.05) were observed, while the acircularity index in the RVO eyes was significantly higher than the fellow eyes (P < 0.05). Additionally, the FD-300 in the RVO eyes was significantly lower than their fellow eyes (P < 0.05). CONCLUSIONS The OCTA reveals that the macular microvasculature of the RVO fellow eyes can be impaired in both the superficial and deep retinal layer as well as the choriocapillary, suggesting the influence of systemic factors in the development of RVO.

Abstract
BACKGROUND We investigated the incidence and risk of retinal vein occlusion (RVO) in end-stage renal disease (ESRD) patients on dialysis in Korea. METHODS In this nationwide cohort study, we used Korean National Health Insurance Service data between 2004 and 2013 for analysis. ESRD patients who started dialysis from 2004 to 2013 and an equal number of controls were selected through propensity score matching. RVO incidence in both cohorts were calculated for 2004-2013 using washout data from 2003. The multivariable Cox proportional hazards model was used to assess the risk of RVO in dialysis cohort. The Kaplan-Meier method was used to generate the cumulative RVO incidence curve. Whether the dialysis modality affects the development of RVO was also evaluated. RESULTS In this study, 74,551 ESRD patients on dialysis and the same number of controls were included. The incidence of RVO was significantly higher in the dialysis cohort than in the control cohort (dialysis = 7.3/1,000 person-years [PY]; control = 1.9/1,000 PY; P < 0.001). The cumulative-incidence of RVO was also significantly higher in the dialysis cohort than in the control cohort (P < 0.001; log-rank test). However, there was no significant difference in the incidence of RVO between the two dialysis methods (P = 0.550; log-rank test). CONCLUSION This study provided epidemiological evidence that receiving dialysis for ESRD could increase the risk of developing RVO. We also found a rapid increase in the incidence of RVO with a longer dialysis period. These results strengthen the relationship between retinal vascular disease and renal function.

Abstract
OBJECTIVE To assess the association between use of sodium-glucose cotransporter 2 (SGLT2) inhibitors and retinal vein occlusion (RVO) using data from the National Health Insurance Service in South Korea. RESEARCH DESIGN AND METHODS We used an active comparator, new user design, and nationwide data from 2014 to 2017. Based on a 1:1 propensity score match, we included 47,369 new users of SGLT2 inhibitors and 47,369 users of other glucose-lowering drugs (oGLDs). In the matched sample, we used the Cox proportional hazards model to estimate hazard ratios (HRs) with 95% CIs for developing RVO. Based on the main outcome, exploratory subgroup analyses were undertaken. RESULTS During a follow-up of 2.57 years, the incidence rate of RVO was 2.19 and 1.79 per 1,000 person-years in patients treated with SGLT2 inhibitors and oGLDs, respectively. The new use of SGLT2 inhibitors was associated with an increased risk of RVO compared with oGLD use (HR 1.264 [95% CI 1.056, 1.513]). In the subgroup analyses, a significant interaction with SGLT2 inhibitors was observed for age and estimated glomerular filtration rate (eGFR); the HR for RVO was higher in patients aged ≥60 years and those with eGFR <60 mL/min/1.73 m2 than in others. CONCLUSIONS In a matched cohort study, we found that SGLT2 inhibitors were associated with a significantly increased risk of RVO. Older patients and those with chronic kidney disease were at higher risk for RVO.

Abstract
BACKGROUND AND OBJECTIVE To characterize contrast sensitivity function (CSF) in patients with retinal vein occlusion (RVO) compared to age-matched controls using novel computerized contrast sensitivity (CS) testing with active learning algorithms. PATIENTS AND METHODS CSF was prospectively measured in RVO patients with visual acuity (VA) greater than 20/200 and age-matched controls using the novel Manifold Contrast Vision Meter implementing quantitative CSF testing. Outcomes included area under the Log CSF (AULCSF), contrast acuity (CA), and CS thresholds at 1, 1.5, 3, 12, and 18 cycles per degree (cpd). A sub-analysis was performed on RVO eyes with good acuity (VA ≥ 20/30). RESULTS Twenty-two eyes with RVO and 63 control eyes were included. Mean AULCSF (± standard deviation) in RVO eyes was 0.817 (0.28) compared to 1.217 (0.28) in controls (P < .0001). Mean contrast acuity in the RVO group was 1.054 (0.19) versus 1.286 ± 0.16 in controls (P < .0001). For individual spatial frequencies, CS loss at 6.0 cpd was most prominent in the RVO group. In 10 RVO eyes with VA of 20/30 or greater, mean AULCSF was 0.978 versus 1.217 in control eyes. (P = .008). CONCLUSIONS CSF in eyes with RVO was found to be significantly reduced compared to age-matched controls. CSF seems to be a promising visual function endpoint with potential applications in clinical practice and future clinical trials. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:392-400.].

Abstract
Retinal vein occlusion (RVO) is associated with atherosclerotic cardiovascular risk factors; however, its association with the specific markers of subclinical atherosclerosis has not yet been established. To investigate this association, we compared 70 patients with RVO to 70 age- and sex-matched patients without RVO. Low-density lipoprotein cholesterol (LDL-C) levels and brachial-ankle pulse wave velocity (baPWV) were significantly higher in the RVO group than in the control group. Carotid plaques (54.3% vs. 28.6%, p = 0.004) were more frequent in the RVO group. Multivariate logistic regression analysis showed that the presence of carotid plaques (odds ratio [OR]: 3.15, 95% confidence interval [CI] 1.38–7.16, p = 0.006), as well as smoking, LDL-C level, and baPWV were associated with RVO. Additionally, a multinomial logistic regression model showed that the presence of carotid plaques (OR: 3.94, 95% CI 1.65–9.41, p = 0.002) and LDL-C level were associated with branch RVO, whereas smoking and baPWV were associated with central RVO. In conclusion, RVO was associated with subclinical atherosclerosis markers, including carotid plaques and baPWV. These results support the hypothesis that atherosclerosis contributes to the etiology of RVO and suggest the evaluation of subclinical atherosclerosis in patients with RVO.

Abstract
PURPOSE Oxidative stress and inflammation have been implicated in the development of retinal vein occlusion (RVO). Oxidation-specific epitopes (OSEs) represent products of oxidative stress that can trigger vascular inflammation and thrombosis. Natural occurring antibodies have been shown to bind oxidation-specific epitopes thereby inhibiting their inflammatory potential and promoting their removal. METHODS This prospective cross-sectional study included 270 patients with RVO and 81 in-hospital control patients. We measured three types of serum levels of oxidation-specific epitope-specific immunoglobulin M and immunoglobulin G antibodies (anti-copper-oxidized LDL [CuOx-LDL], antiphosphocholine [PC], anti-malondialdehyde-modified LDL [MDA-LDL]). History of arterial hypertension, hyperlipidemia, myocardial infarction, diabetes mellitus, stroke, smoking status, and several laboratory parameters were determined to control for potential confounders. RESULTS Compared with controls, patients with RVO had significantly lower levels of immunoglobulin M and immunoglobulin G antibodies against CuOx-LDL and PC, and significantly lower levels of immunoglobulin G but not immunoglobulin M antibodies against MDA-LDL. The association between RVO patients and lower levels of these antibodies prevailed upon multivariable adjustment. CONCLUSION These prospective data show that antibodies against oxidation-specific epitope are lower in patients with RVO compared with control patients and support the concept that oxidative stress and inflammation play key roles in the development and subsequent complications in RVO.

A Multimodal Imaging-Based Deep Learning Model for Detecting Treatment-Requiring Retinal Vascular Diseases: Model Development and Validation Study. JMIR Med Inform 2021; 9:e28868. [PMID: 34057419 PMCID: PMC8204240 DOI: 10.2196/28868] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 04/18/2021] [Accepted: 05/03/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Retinal vascular diseases, including diabetic macular edema (DME), neovascular age-related macular degeneration (nAMD), myopic choroidal neovascularization (mCNV), and branch and central retinal vein occlusion (BRVO/CRVO), are considered vision-threatening eye diseases. However, accurate diagnosis depends on multimodal imaging and the expertise of retinal ophthalmologists. OBJECTIVE The aim of this study was to develop a deep learning model to detect treatment-requiring retinal vascular diseases using multimodal imaging. METHODS This retrospective study enrolled participants with multimodal ophthalmic imaging data from 3 hospitals in Taiwan from 2013 to 2019. Eye-related images were used, including those obtained through retinal fundus photography, optical coherence tomography (OCT), and fluorescein angiography with or without indocyanine green angiography (FA/ICGA). A deep learning model was constructed for detecting DME, nAMD, mCNV, BRVO, and CRVO and identifying treatment-requiring diseases. Model performance was evaluated and is presented as the area under the curve (AUC) for each receiver operating characteristic curve. RESULTS A total of 2992 eyes of 2185 patients were studied, with 239, 1209, 1008, 211, 189, and 136 eyes in the control, DME, nAMD, mCNV, BRVO, and CRVO groups, respectively. Among them, 1898 eyes required treatment. The eyes were divided into training, validation, and testing groups in a 5:1:1 ratio. In total, 5117 retinal fundus photos, 9316 OCT images, and 20,922 FA/ICGA images were used. The AUCs for detecting mCNV, DME, nAMD, BRVO, and CRVO were 0.996, 0.995, 0.990, 0.959, and 0.988, respectively. The AUC for detecting treatment-requiring diseases was 0.969. From the heat maps, we observed that the model could identify retinal vascular diseases. CONCLUSIONS Our study developed a deep learning model to detect retinal diseases using multimodal ophthalmic imaging. Furthermore, the model demonstrated good performance in detecting treatment-requiring retinal diseases.

Abstract
PURPOSE To evaluate the association between serum vitamin B12/folate and retinal vein occlusion (RVO). METHODS A comprehensive search of the PubMed database was performed, which identified 271 abstracts to be screened. Ten studies met our inclusion criteria and a meta-analysis of these comparative case-control studies was performed on the mean ± standard deviation serum vitamin B12 and folate levels, without language restrictions. Nine studies with 720 patients with RVO and 613 controls were included in the meta-analysis for vitamin B12, and 10 studies with 784 patients with RVO and 677 controls in the meta-analysis for folate. RESULTS There was no statistically significant difference between patients with RVO and controls in serum vitamin B12 levels (mean difference: - 40.25 pg/mL, p = 0.28), either central RVO (mean difference: - 18.24 pg/mL, p = 0.71) or branch RVO (mean difference: - 23.56 pg/mL, p = 0.48). On the contrary, the plasma folate level was significantly lower in RVO patients than in controls (mean difference: - 1.34 ng/mL, p = 0.001), as well as in patients with CRVO compared to controls (mean difference: - 1.48 ng/mL, p = 0.006), but not in BRVO patients (mean difference: - 0.72 ng/mL, p = 0.11). CONCLUSIONS RVO is associated with low serum folate levels, but not with serum vitamin B12 levels.

Abstract
Purpose To observe the changes in macular microvascular structure and the correlation between anatomy and visual function in patients with macular edema secondary to branch retinal vein occlusion (BRVO) treated with antivascular endothelial growth factor for one year. Methods This prospective study enrolled 39 patients (one eye per patient) who received intravitreal injections of ranibizumab for macular edema secondary to BRVO. All patients received a minimum of 3 initial monthly ranibizumab injections and criteria-driven pro re nata (PRN) dosing thereafter for visual acuity (VA) and central retinal thickness (CRT) stabilization. The follow-up period of this study was one year. The vascular density (VD) of the superficial retinal capillary plexus (SCP) and deep retinal capillary plexus (DCP), the foveal avascular zone (FAZ) area, the FAZ perimeter, the VD within a 300 μm wide ring surrounding the FAZ (FD-300), and the acircularity index (AI) were measured automatically by optical coherence tomography angiography (OCTA) at baseline, month 6, and month 12. Results Compared with those before treatment, the VD of the SCP significantly decreased 6 months after treatment (P < 0.05), while the area and perimeter of the FAZ increased significantly (P < 0.01). After 12 months of treatment, the area and perimeter of the FAZ increased significantly (P < 0.01). There was no significant difference in any parameters between 12 months and 6 months after treatment (P > 0.05). The change in BCVA was negatively correlated with the VD of the SCP at 12 months (P=0.0447, r = -0.3233). There was a relationship between the DBP and AI, and CRT was related to VD of DCP at baseline (P=0.028, 0.0209; r = 0.383, -0.384). The PERIM and AI at 12 months were significantly associated with the recurrence of macular edema, and the changes in vascular density in the SCP and PERIM were significantly associated with the number of injections within 12 months (P < 0.05). Conclusions One year after ranibizumab treatment, the area and perimeter of the FAZ were enlarged, while the VD of the SCP and DCP remained stable, which indicated that ranibizumab treatment did not improve macular blood supply and macular ischemia in BRVO patients.

Abstract
PURPOSE To demonstrate the effect of averaging multiple en face optical coherence tomography angiography images on the correlation between retinal microvasculature quantitative metrics and best-corrected visual acuity (BCVA) in eyes with retinal vein occlusion. METHODS A cross-sectional cohort with unilateral retinal vein occlusion was imaged in both eyes. Five 3 mm × 3-mm spectral domain optical coherence tomography angiography images were averaged, and quantitative parameters from averaged versus single images were correlated with logMAR BCVA. Regression analyses were performed to correlate quantitative metrics with BCVA. RESULTS Ten patients (5 male, average age 64.3 years) were included. Among retinal vein occlusion eyes, vessel length density was significantly less in averaged versus a single image for both the superficial retinal layer (15.5 ± 2.5 vs. 17.8 ± 2.4/mm, P = 0.05) and deep retinal layer (16.2 ± 1.4 vs. 18.5 ± 1.6/mm, P = 0.003). Multivariate linear regression showed an increased R value with averaging (0.93 to 0.95, for single and averaged groups, respectively). Foveal avascular zone circularity was associated with BCVA on single images (coefficient = -0.96, P = 0.002), but not with averaged images (P = 0.063). CONCLUSION Scan averaging of en face optical coherence tomography angiography images improves the clarity of vessels and may allow for more accurate quantification of vessel metrics. Quantitative metrics are significantly associated with BCVA, and averaging does not further improve this association compared with single-scan analysis.

Abstract
Aims To compare the relationship between the nonperfusion area (NPA) on ultra-widefield fluorescein angiography (UWFFA) and the nonflow area (NFA) on optical coherence tomographic angiography (OCTA) in retinal vein occlusion (RVO). Methods Cross-sectional study. 46 eyes of 46 RVO patients who underwent UWFFA and OCTA. NPA and ischemic index (ISI) were quantified on UWWFA. NFA, vessel density (VD) of the superficial capillary plexus (SCP), the deep capillary plexus (DCP), and the size foveal avascular zone (FAZ) on 3 ∗ 3 mm OCTA were measured. The association of the NPA and ISI on UWWFA and the parameters on OCTA were analyzed. Spearman correlation was used for statistical testing. Results The NPA and ISI on UWFFA were significantly correlated with the NFA on OCTA in RVO, and r values were 0.688 (p < 0.01) and 0.680 (p < 0.01), respectively. VD in the SCP of the temporal quadrant was negatively correlated with NPA and ISI, and r values were -0.346 (p < 0.05) and -0.337 (p < 0.05), respectively. VD in the DCP of the temporal quadrant was negatively correlated with the NPA, and the r value was -0.246 (p < 0.05). No significant correlation was found between the NPA and ISI on UWFFA and VD of other quadrants in the SCP or DCP and the FAZ area on OCTA. Conclusion NPA in the peripheral retina was correlated with NFA in macula. NFA detected by OCTA could be an indicator of the ischemic status in RVO.

Abstract
Background and Objective: To evaluate and compare the structural changes of retinal vasculature after intravitreal dexamethasone implant (Ozurdex) insertion and antivascular endothelial growth factor (anti-VEGF) injection in patients with branched retinal vein occlusion (BRVO) using optical coherence tomography angiography (OCTA).Study Design/Materials and Methods: We retrospectively analyzed 39 patients with unilateral BRVO. Subjects were divided into two groups according to treatment agent: Ozurdex (n = 18) and anti-VEGF (n = 21). Swept Source (SS) OCT and OCTA were performed and images were analyzed quantitatively using ImageJ (National Institutes of Health) software. Intravitreal implant and anti-VEGF injections were performed following a prn regimen. The specific anti-VEGF agent used was chosen among bevacizumab, ranibizumab and aflibercept.Results: Of the 39 patients (mean ± SD age, 70.0 ± 8.9 years [range, 48-89 years]; 20 men [51.0%]) with unilateral BRVO, in an independent two-sample t test, there was greater vascular reperfusion of the choriocapillaris slab in the intravitreal Ozurdex implant group than in the anti-VEGF group using the angiography mode (P = .013). Increased number of particles was more prominent in intravitreal anti-VEGF injection group than intravitreal Ozurdex implant group in outer retina slab of En-face mode (P = .039). There was no statistically significant difference between the 2 treatment groups in relation to the Early Treatment Diabetic Retinopathy Study (ETDRS) density map and other angiography slabs; and the superficial, deep, and outer retina.Conclusions: Results of a quantitative analysis of OCTA images using ImageJ software suggest that the intravitreal Ozurdex implant induced increased retinal vascular perfusion compared with anti-VEGF injection for the treatment of BRVO.

Abstract
PURPOSE To analyze the repeatability of vessel density (VD) measurements and manual foveal avascular zone (FAZ) measurements using optical coherence tomography angiography (OCTA) in patients with retinal vein occlusion (RVO) without macular edema. METHODS The study population consisted of patients with RVO and central macular thickness <300 μm. For each subject, measurements were performed twice with a 5-minute interval. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were calculated to analyze the repeatability of results obtained with the OCTA device. To identify factors related to repeatability, we performed Pearson correlation analyses based on the CV of potential factors. RESULTS A total of 48 eyes were included in the study. The ICCs of the VDs in superficial capillary plexus (SCP) and the deep capillary plexus (DCP) were 0.748 and 0.665, respectively, and the CVs of the VDs in SCP and DCP were 9.1% and 12.6%, respectively. The ICCs associated with the FAZ of the superficial layer (SFAZ) and that of the deep layer (DFAZ) were 0.965 and 0.956, respectively, and the CV of the SFAZ and DFAZ were 8.8% and 9.7%, respectively. From Pearson correlation analyses, OCTA quality was significantly correlated with the CV of the VDs of SCP and DCP. However, there were no variables that were significantly correlated with the CV of SFAZ and DFAZ, including OCTA quality. CONCLUSIONS VD measurements in the SCP layer using OCTA exhibited good repeatability, and VD measurements in the DCP layer exhibited relatively low repeatability compared to that of SCP layer measurements in patients with RVO without macular edema after treatment with bevacizumab. Manual measurement of the FAZ area in both SCP and DCP layers resulted in good repeatability. In addition, the repeatability of VD measurements in SCP and DCP layers was correlated with OCTA image quality.

Abstract
BACKGROUND/AIMS Clinical trials suggest anti-vascular endothelial growth factor is more effective than intravitreal dexamethasone as treatment for macular oedema secondary to branch retinal vein occlusion. This study asks if 'real world' data from a larger and more diverse population, followed for a longer period, also support this conclusion. METHODS Data collected to support routine care at 27 NHS (National Health Service) Trusts between February 2002 and September 2017 contained 5661 treatment-naive patients with a single mode of treatment for macular oedema secondary to branch retinal vein occlusion and no history of cataract surgery either during or recently preceding the treatment. Number of treatment visits and change in visual acuity from baseline was plotted for three treatment groups (anti-vascular endothelial growth factor (anti-VEGF), intravitreal dexamethasone, macular laser) for up to 3 years. RESULTS Mean baseline visual acuity was 57.1/53.1/62.3 letters in the anti-VEGF/dexamethasone/macular laser groups, respectively. This changed to 66.72 (+9.6)/57.6 (+4.5)/63.2 (+0.9) at 12 months. Adequate numbers allowed analysis at 18 months for all groups (66.6 (+9.5)/56.1 (+3.0)/60.8 (-1.5)) and for anti-VEGF at 36 months (68.0, +10.9) Mean number of treatments were 5.1/1.5/1.2 at 12 months, 5.9/1.7/1.2 at 18 months for all three groups and 10.3 at 36 months for anti-VEGF. CONCLUSIONS Visual acuity improvements were higher and more sustained with anti-VEGF. Higher treatment burden occurred with anti-VEGF but this reduced over 36 months. Patients with better vision at baseline than those in the clinical trials maintained high levels of vision with both anti-VEGF and dexamethasone.

Abstract
Background This study evaluated the effects of dexamethasone intravitreal implant on treatment-naïve branch retinal vein occlusion (BRVO)-induced macular edema (ME), and the risk factors for earlier repeated treatment. Methods Patients treated from 2013 to 2016 were enrolled. The patients’ demographics, medical history, best-corrected visual acuity (BCVA), and central retinal thickness (CRT) were recorded. Risk factors for repeated treatment were identified using a Cox proportional hazard model and logistic regression. Results 29 patients (mean age: 58.64 ± 13.3 years) were included; 44.8% received only one injection, while 55.2% received two or more. The mean initial CRT was 457.8 ± 167.1 μm; the peak CRT and final CRT improved significantly to 248.9 ± 57.9 μm and 329.2 ± 115.1 μm, respectively. The peak BCVA improvement and final improvement were 29.5 ± 23.5 approximate ETDRS letters and 19.8 ± 24.4 letters, respectively, with 62.1% of patients improving by more than 15 letters. Older age, higher initial CRT, and diabetes were the risk factors for multiple injections. Conclusion Dexamethasone intravitreal implant results in significant peak CRT and BCVA improvements, while older age, higher initial CRT, and diabetes are risk factors for repeated injections. The optimal retreatment schedule for these patients should be further explored.

Abstract
Purpose: The purpose of this study was to evaluate health-related quality of life in patients with retinal vein occlusion (RVO) and investigate the possible risk factors for poor quality of life in patients with RVO.Methods: Participants in the study were 67 patients with RVO, 42 male and 25 female, mean-aged 73.1 ± 10.9 years, and 70 sex- and age-matched controls. Demographic data, lifestyle factors and medical history were recorded. All patients underwent best-corrected visual acuity measurement, dilated fundoscopy and optical coherence tomography. All participants completed two questionnaires assessing quality of life (EQ-5D, NEI VFQ-25). Risk factors for health-related quality of life in RVO patients were investigated.Results: Patients with RVO exhibited significantly lower composite score for VFQ-25 compared to controls (74.1 ± 3.8 vs. 91.7 ± 3.9 for patients and controls, respectively, p < .001). In addition, RVO patients had significantly lower EQ-5D Index score compared to controls (0.88 ± 0.15 vs. 0.92 ± 0.12 for patients and controls, respectively, p = .043). Risk factors associated with quality of life in patients with RVO were found the alcohol consumption, the presence of thyroidopathy, coagulation disorders, visual acuity in the eye with RVO, central retinal thickness, the type of edema, the presence of ischemia and the condition of external limiting membrane. In multivariate analysis, only alcohol consumption and visual acuity in the eye with RVO were found to be independent risk factors, affecting quality of life in RVO patients.Conclusions: Patients with RVO presented lower quality of life in comparison with controls. Potential risk factors should be taken into account and their early detection may improve quality of life in such patients and lead to targeted health policies.

Abstract
Purpose To investigate the characteristics of the retinal periarterial capillary-free zone (paCFZ) with wide-field swept-source optical coherence tomography angiography (SS-OCTA) in eyes with branch retinal vein occlusion (BRVO). Methods Seventy treatment-naïve eyes with BRVO and 35 healthy eyes were included. The paCFZ areas, artery calibers, and areas of the major arteries in the unaffected quadrants of BRVO eyes were measured in 12 × 12-mm SS-OCTA images and compared with those of the contralateral eyes and healthy eyes. Other multimodal imaging data were collected. Results There were no significant differences in the unaffected artery caliber or area among the three groups (all P > 0.05). The unaffected paCFZ areas and the ratios of the unaffected paCFZ area to the counterpart artery area (paCFZ/artery area) of the major arteries were significantly larger than those in the contralateral or healthy eyes (all P < 0.05). Subgroup analysis revealed that the paCFZ/artery area value differed significantly between ischemic and nonischemic BRVO eyes (P < 0.01). The paCFZ/artery area value was positively correlated with logMAR best-corrected visual acuity, symptom duration, central macular thickness, and retinal nonperfusion area in BRVO. Conclusions Quantitative SS-OCTA measurements confirmed enlarged paCFZs along the unaffected major retinal arteries in BRVO eyes. The paCFZ parameters were correlated with symptom duration, retinal ischemia, and visual function. Translational Relevance Retinal periarterial capillary-free zones in BRVO can be non-invasively measured by SS-OCTA, assisting in clinically identifying retinal ischemia and evaluating visual function.

Abstract
PURPOSE To compare the efficacy of intraoperative intravitreal dexamethasone implant for macular edema secondary to diabetic retinopathy (DME), retinal vein occlusion (RVO), and noninfectious posterior uveitis. METHODS A retrospective review of 62 patients (29 men and 33 women; mean age 51.19 ± 14.41 years; 65 eyes) was performed. Best-corrected visual acuity (in logarithm of the minimal angle of resolution), central foveal thickness, intraocular pressure, and postoperative edema-free period were postoperatively assessed up to 1 year. The preoperative and postoperative numbers of other intravitreal injections needed were compared. RESULTS Best-corrected visual acuity gradually improved in the DME group (from 0.87 to 0.51) but failed to improve from Month 3 onward in the RVO and uveitis groups. Central foveal thickness decreased in all groups, especially in the DME group (from 550.93 to 338.10 μm). Edema-free period was longest in the DME group (19.34 ± 15.12 months), followed by the uveitis (12.91 ± 7.85 months) and RVO (8.50 ± 8.76 months) groups. Subjects in the uveitis group used more intraocular pressure-lowering agents (1.00 ± 1.27) than those in the DME (0.13 ± 0.49) and RVO (0.36 ± 0.79) groups. Increased intraocular pressure events were most frequent in postoperative Week 1, especially in the uveitis group. CONCLUSION Vitrectomy combined with intravitreal dexamethasone implant for DME, RVO, and noninfectious posterior uveitis had a favorable clinical outcome.

Abstract
A 53-year-old man presented to his optician with blurring of vision in the right eye and was diagnosed to have branch retinal vein occlusion. Over the following 3 months, he had further progressive visual impairment due to right central retinal vein occlusion (CRVO) and then left CRVO. Soon thereafter, during a hospital admission for infected submandibular gland, he was noted to have secondary hypothyroidism and persistent hypokalaemia which led to the diagnosis of Cushing's syndrome. This case was unusual as the patient did not manifest any classical features of Cushing's syndrome at the time of presentation with bilateral CRVO, and only 3 months later had dramatic weight loss, muscle weakness and acute psychosis. He received intravenous etomidate and underwent emergency transsphenoidal hypophysectomy with dramatic clinical and biochemical improvement and complete visual recovery in the left eye but unfortunately vision in the right eye remained limited to hand movements.

Abstract
Purpose The pathomechanism leading to retinal vein occlusion (RVO) is unclear. Mechanical compression, thrombosis, and functional contractions of veins are discussed as the reasons for the increased resistance of venous outflow. We evaluated changes in the retinal venous pressure (RVP) following intravitreal injection of anti-vascular endothelial growth factor (VEGF) agent to determine the effect on RVO-related macular edema. Methods Twenty-six patients with RVO-related macular edema (16 branch RVOs [BRVOs] and 10 central RVOs [CRVOs], age 72.5 ± 8.8 years) who visited our hospital were included in this prospective study. Visual acuity (VA), intraocular pressure (IOP), central retinal thickness (CRT) determined by macular optical coherence tomography, and RVP measured using an ophthalmodynamometer were obtained before intravitreal injection of ranibizumab (IVR) and 1 month later. Results Comparison of the BRVOs and CRVOs showed that VA was significantly improved by a single injection in BRVOs (P < 0.0001; P = 0.1087 for CRVOs), but CRT and RVP were significantly decreased without significant difference in IOP after the treatment in both groups (P < 0.0001). Conclusion The anti-VEGF treatment resulted in a significant decrease in the RVP, but the RVP remained significantly higher than the IOP. An increased RVP plays a decisive role in the formation of macula edema, and reducing it is desirable.

Abstract
AIMS To investigate the risk of retinal vein occlusion (RVO) in new-onset diabetes mellitus (DM) patients. METHODS This nationwide, retrospective, matched cohort study included 240,761 DM patients registered between January 2003 and December 2005 in the Longitudinal Cohort of Diabetes Patients database. An age- and sex-matched control group comprising 240,761 non-DM patients (case: control = 1:1) was selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient from the index date until December 2013 was collected. The incidence and risk of RVO were compared between the two groups. Cox proportional hazard regression analysis was performed to calculate the adjusted hazard ratio (HR) for RVO after adjustment for potential confounders. The RVO cumulative incidence rate was obtained using Kaplan-Meier analysis. RESULTS During the follow-up period, 1,456 DM patients developed RVO (491, central retinal vein occlusion; 965, branch retinal vein occlusion). There was a significantly elevated risk of RVO in DM patients compared with the controls (incidence rate ratio = 1.91, 95% confidence interval [CI] = 1.75-2.08). Patients with DM showed significant risk of RVO after adjustment for potential confounders (hypertension, hyperlipidemia, congestive heart failure, coronary artery disease, and chronic renal disease) in the full cohort (adjusted HR = 1.76, 95% CI = 1.61-1.93). Additionally, patients with hypertension had a significantly higher risk of RVO than patients without hypertension after adjustment for other confounders in the cohort (adjusted HR = 1.50, 95% CI = 1.36-1.65). CONCLUSIONS We found that patients with DM have increased risks of RVO. In addition to blood pressure control, we recommend educating patients with DM about RVO, to prevent its subsequent occurrence.

Abstract
The purpose of this study was to determine the efficacy of combined intravitreal bevacizumab and triamcinolone in the treatment of macular edema due to retinal vein occlusion. A prospective randomized trial was conducted in the Department of Ophthalmology, Osijek University Hospital Centre in Osijek including 51 patients divided into three groups depending on the drug received. The first group received 1.25 mg intravitreal bevacizumab, the second group received 1 mg intravitreal triamcinolone, and the third group received a combination of 1.25 mg bevacizumab and 1 mg intravitreal triamcinolone on the same day. Changes in the central macular thickness, intraocular pressure and visual acuity were monitored during the follow up period. The retinal perfusion status was evaluated by fluorescein angiography. The group that received combined treatment had better outcome in terms of reduction of macular thickness. There was no statistically significant intraocular pressure elevation among the three treatment groups or within each group of patients. A positive trend regarding visual improvement was observed in the group receiving combined treatment in spite of the lowest initial visual acuity, highest value of macular thickness and longest mean duration of symptoms. In conclusion, combined treatment with bevacizumab and triamcinolone for the treatment of retinal vein occlusion is more potent, safe, efficient and cost-effective. It can also be recommended because fewer injections are needed in patients undergoing treatment for macular edema.

Abstract
Purpose: We hypothesized that the thickness map from macular ganglion cell analysis (GCA) acquired from spectral-domain optical coherence tomography can be used to differentiate retinal vein occlusion (RVO) from glaucoma. Methods: In this retrospective case control study, 37 patients with resolved RVO and 74 patients with primary open-angle glaucoma (POAG) were enrolled. Two independent examiners diagnosed patients with RVO or POAG based on the topographic pattern in the GCA thickness map. Inter-observer agreement for a decision between RVO and POAG was assessed using kappa statistics. Diagnostic specificity and accuracy were calculated. Results: Inter-observer agreement was good, with a kappa value of 0.765 (95% confidence interval, 0.634–0.896, p < 0.001). The diagnostic specificity of RVO from POAG using the GCA thickness map was 93.2% and diagnosis accuracy was 80.4%. Conclusions: An irregular GCA thickness map represents a simple and convenient differential diagnostic clue to distinguish RVO from POAG.

[PMID: 32991963 DOI: 10.1016/j.ygeno.2020.09.055] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Revised: 09/07/2020] [Accepted: 09/23/2020] [Indexed: 10/23/2022]
Abstract
Hyperlipidemia-induced retinal vascular dysfunction is a complex pathological process. circRNAs are important regulators of biological processes and disease progression. However, the expression pattern of circRNAs in hyperlipidemia-induced retinal vascular dysfunction remains unclear. Herein, we used a murine model of hyperlipidemia and identified 317 differentially expressed circRNAs between hyperlipidemic retinas and normolipidemic retinas by circRNA microarrays. GO analysis indicated that the host genes of dysregulated circRNAs were targeted to cell differentiation (ontology: biological process), cytoplasm (ontology: cellular component), and protein binding (ontology: molecular function). Pathway analysis revealed that circRNAs-mediated network was mostly enriched in focal adhesion signaling. Notably, circLDB1 was significantly up-regulated in the serum of coronary artery disease patients and aqueous humor of age-related macular degeneration patients. circLDB1 regulated endothelial cell viability, proliferation, and apoptosis in vitro. Thus, circRNAs are the promising targets for the prediction and diagnosis of hyperlipidemia-induced vascular diseases.

[DOI: 10.1136/bjophthalmol-2020-316947] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 08/11/2020] [Accepted: 09/14/2020] [Indexed: 11/04/2022]
Abstract
AimsTo investigate the association between incident retinal vein occlusion (RVO) and the subsequent development of cancer.MethodsIn this nationwide population-based retrospective study using 2002–2013 National Health Insurance Service database which covers the entire South Korean population, 186 701 incident RVO patients and their 1:1 propensity-score matched controls were included. We defined the fixed cohort from January 1st, 2004 to December 31st, 2013; the cohort included patients who suffered incident RVO after entering the cohort and their matched controls, and excluded patients having any cancer history before entering the cohort. The association of RVO and cancer was assessed by time-varying covariate Cox regression models; Model 1 included RVO as a time-varying covariate, Model 2 included Model 1 plus demographic information and Model 3 included Model 2 and comorbidities.ResultsRVO was associated with an increased risk of subsequent cancer (HR=1.29; 95% CI, 1.26–1.31 in Model 1), which was consistent in Models 2 and 3. The incidence rate of overall cancer during the study period was 25.55 (95% CI, 25.19–25.91) per 1000 person-years in the RVO group and 18.62 (95% CI, 18.46–18.79) per 1000 person-years in the control group. In the subgroup analysis, haematological malignancies showed the highest association with RVO (HR=1.65; 95% CI, 1.49–1.83).ConclusionPatients with RVO have an increased risk of subsequent cancer development even after adjusting for demographic factors and comorbidities. Further study is warranted to elucidate these associations to provide proper recommendations for RVO patients regarding the cancer screening.

Abstract
PURPOSE Intravitreal ranibizumab (RNB) and dexamethasone intravitreal implant (DII) were developed in the recent past and has been widely used for macular edema secondary to BRVO. We aimed to assess the efficacy and safety of intravitreal ranibizumab (RNB) compared to dexamethasone intravitreal implant (DII) in patients with macular edema secondary to branch retinal vein occlusion (BRVO). METHODS We performed a comprehensive search on topics that assess RNB and DII in patients with macular edema secondary to BRVO from several electronic databases. RESULTS There were 678 subjects from five studies. Ranibizumab was associated with a greater increase in best-corrected visual acuity (BCVA; mean difference 9.13, I2: 0%) compared to DII. Ranibizumab also demonstrated a greater ⩾10 (OR 2.76, I2: 0%) and ⩾15 letters (OR 2.78, I2: 0%) gain. RNB has better BCVA (logMAR scale) improvement at 6 months' follow up (mean difference -0.15, I2: 64%) in favor of RNB. Higher IOP was found in DII group on follow-up (mean difference -2.92, I2: 89%) and RNB has lesser IOP ⩾10 mmHg increase compared to DII (OR 0.08, I2: 0%). Cataract formation and/or progression was less in RNB (OR 0.53, I2: 75%). The need for rescue laser was similar the two groups. CONCLUSION Intravitreal RNB was more effective with less pronounced effect on IOP and cataract formation and/or progression compared to DII for patients with macular edema secondary to BRVO.

Abstract
PURPOSE Previous studies examining the association of retinal vein occlusion (RVO) and cardiovascular events have been inconsistent and have mostly focused on stroke and myocardial infarction. The goal of this study is to use meta-analysis to examine the available evidence examining the association of RVO with incident cardiovascular events and mortality. METHODS Systematic review and meta-analysis of all longitudinal cohort studies published in PubMed, Embase, and the Cochrane Library from inception to April 7, 2018, that evaluated the association of baseline RVO and incident cardiovascular events and/or mortality, that provided multivariate-adjusted risk estimates with 95% confidence intervals (95% CIs), and that had average follow-up ≥1 year. The Newcastle-Ottawa scale was used to assess study quality. Multivariate-adjusted risk estimates with 95% CI along with study characteristics were extracted from each study, and pooled risk ratios (RRs) with 95% CI were generated using a random-effects model with inverse-variance weighting to account for heterogeneity. Main outcomes were incident stroke (fatal or nonfatal), myocardial infarction, heart failure, peripheral arterial disease, all-cause mortality, and cardiovascular mortality. RESULTS Fifteen cohort studies with a total of 474,466 patients (60,069 with RVO and 414,397 without RVO) were included. Each study had Newcastle-Ottawa scale score ≥6, indicating moderate-to-high quality. Retinal vein occlusion was associated with increased risk of stroke (RR = 1.45; 95% CI, 1.31-1.60), myocardial infarction (RR = 1.26; 95% CI, 1.17-1.37), heart failure (RR = 1.53; 95% CI, 1.22-1.92), peripheral arterial disease (RR = 1.26; 95% CI, 1.09-1.46), and all-cause mortality (RR = 1.36; 95% CI, 1.02-1.81), but was not associated with increased risk of cardiovascular mortality (RR = 1.78; 95% CI, 0.70-4.48). CONCLUSION This review suggests patients with RVO have an increased risk of cardiovascular events and all-cause mortality. More studies are needed to determine the highest risk periods for cardiovascular events and mortality after RVO and whether immediate cardiovascular evaluation and intervention will improve outcomes.

Abstract
Purpose: To provide a detailed review on the therapeutic efficacy of conbercept for the management of ocular vasculopathies. Methods: A comprehensive literature search of various electronic databases was performed. Results: Ocular vasculopathy is one of the major causes of visual impairment and blindness which includes a range of disorders. Vascular endothelial growth factor (VEGF) regulates angiogenesis, enhances vascular permeability, and drives the formation of neovascularization. Anti-VEGF therapy has been shown to prevent vision loss or potentially improve vision in patients with exudative or neovascular retinal disease. The most recent anti-VEGF drug in China is conbercept. In the USA and Europe, bevacizumab is the most recently approved anti-VEGF agent. Conclusions: Conbercept serves as another anti-VEGF option for patients with neovascular AMD and other retinal vascular disorders. There have not been many clinical trials that study conbercept as compared with other currently available anti-VEGF drugs. There is a need for large-scale, well-designed, randomized clinical trials to ensure its long-term safety and efficacy and to determine if it has any advantages over other anti-VEGF agents.

Abstract
OBJECTIVE Although several risk factors for retinal vein occlusion (RVO) are known, what triggers RVO is unclear in many cases. We aimed to evaluate the relevance of multiple risk factors in patients with RVO. METHODS The Gutenberg RVO Study is an observational case-control study that assessed thrombophilic, cardiovascular, ophthalmic, and drug-related risk factors in participants with RVO and the same number of matched controls. Conditional logistic regression analysis was chosen to estimate the risk of RVO due to several risk factors. RESULTS Of 92 patients with RVO, 46 (50%) had central RVO, 31 (33.7%) had branch RVO, and 15 (16.3) had hemi-RVO. Systemic hypertension was associated with RVO [any RVO: odds ratio (OR): 1.81; 95% confidence interval (CI): 1.14-2.88; branch RVO: OR: 2.56; 95% CI: 1.08-6.10]. The most frequent combinations of risk factors were hypertension with dyslipidemia (33 of 92, 35.9%) and hyperhomocysteinemia and high levels of factor VIII (10 of 92, 10.9%). An increase in the risk sum score by one additional risk factor corresponded to ORs of 1.74 (95% CI: 1.31-2.32) for cardiovascular risk factors, 1.38 (95% CI: 1.04-1.82) for thrombophilic risk factors, and 1.43 (95% CI: 1.20-1.70) for the total number of risk factors for RVO. CONCLUSION Cardiovascular risk factors are more important than other risk factors for the presence of RVO. The risk of RVO increased by approximately 40% with any additional risk factor and by 70% with any additional cardiovascular risk factor.

Abstract
A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion. Her left vision was 20/50, and schisis was observed inferotemporally. She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane. Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery. However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers. She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion. After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery. The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.

Abstract
AIMS Hyperreflective foci (HF), detected in the retina of diabetic patients, suggest the presence of microglial activation and migration, while controversies still remain for the origin of HF to be precursors of hard exudates. We investigated the presence of HF and their association with dyslipidemia in serous retinal detachment (SRD)-type diabetic macular edema (DME). METHODS Forty-two eyes in 42 patients with diabetic retinopathy (DR) and 22 eyes in 22 patients with branch retinal vascular occlusion (BRVO) showing macular edema were included in this study. The medical records and OCT findings were retrospectively reviewed in patients with SRD-type DME and compared with those with BRVO. The mean number of HF, the mean choroidal thickness, and lipid profiles were analyzed and compared between groups. RESULTS The mean number of HF was significantly higher in DR group compared to BRVO group. Significant correlation of HF was noted with triglycerides (r = 0.523, P = 0.002). Triglycerides were significantly associated with HF by linear regression (β = 0.012, 95% CI 0.001-0.024, P = 0.034) and remained significantly associated by multiple linear regression (β = 0.014, 95% CI 0.003-0.025, P = 0.014). CONCLUSIONS HF on OCT of DME patients could be indicative of activated microglia. HF are associated with dyslipidemia, especially high triglycerides, suggesting inflammatory reaction from dyslipidemia in diabetic retina.

Abstract
This study was performed to evaluate clinical characteristics of branch retinal vein occlusion (BRVO) patients with increased retinal haemorrhage during macular oedema (MO) treatment. Patients were divided into increased and non-increased retinal haemorrhage groups. The former group was sub-divided based on the degree of increase: < 50% or ≥ 50%. Baseline characteristics, clinical data, and best vision achieved before and after increased retinal haemorrhage were assessed. Sixty-eight eyes of 68 patients were included. Forty-six eyes were non-increased, 11 eyes experienced < 50% increase in retinal haemorrhage, and 11 eyes had ≥ 50% increase. Ischaemic BRVO was related to increased haemorrhage based on the multivariate analysis. The ≥ 50% increase group exhibited higher baseline central subfield macular thickness (CSMT), poorer baseline best corrected visual acuity (BCVA), and longer mean periods between the final intravitreal injections and the time increased retinal haemorrhages were observed, compared to the < 50% group. The best vision achieved before and after increased haemorrhage was significantly worse in the ≥ 50% group. In conclusion, the ischaemic type of BRVO is related to increased retinal haemorrhage during MO treatment, and a ≥ 50% increase in haemorrhages is associated with higher CSMT and poorer BCVA at baseline, with poor visual gain.

Abstract
OBJECTIVES We performed this meta-analysis to assess the correlation of retinal vein occlusion (RVO) and chronic kidney disease (CKD). METHODS We searched PubMed, Embase, Web of Science and Cochrane Library for population-based studies reporting the CKD as associated factor to RVO, central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). Then we pooled the data for analysis. RESULTS After screening potential literature, 12 eligible studies with 23,656,214 individuals were finally included in quantitative synthesis. The pooled prevalence (95% confidence interval [CI]) of CKD in RVO group was 10.9% (95% CI: 6.6%, 15.1%). The pooled prevalence of any RVO in end stage renal disease (ESRD) group was 1.8% (95% CI: 1.6%, 2.1%). The prevalence of CKD was significantly higher in subjects diagnosed with RVO than non-RVO participants (odds ratio [OR]: 3.30; 95% CI: 2.28, 4.76; p < 0.001). CRVO subjects had a higher prevalence of CKD than BRVO patients (OR: 2.17; 95% CI: 1.28, 4.66; p = 0.004). In a similar manner, compared to non-ESRD subjects, ESRD patients had significantly higher prevalence of RVO (OR: 2.19; 95% CI: 1.97, 2.43; p < 0.001), CRVO (OR: 2.61; 95% CI: 2.17, 3.15; p < 0.001) and BRVO (OR: 2.01; 95% CI: 1.76, 2.30; p < 0.001). CONCLUSION The prevalence of CKD increases in RVO patients, especially in CRVO. And in turn, the prevalence of RVO also increases in ESRD patients. The data support a correlation of RVO and CKD.
