Abstract
Real-time fundus images captured to detect multiple diseases are prone to different quality issues like illumination, noise, etc., resulting in less visibility of anomalies. So, enhancing the retinal fundus images is essential for a better prediction rate of eye diseases. In this paper, we propose Lab color space-based enhancement techniques for retinal image enhancement. Existing research works does not consider the relation between color spaces of the fundus image in selecting a specific channel to perform retinal image enhancement. Our unique contribution to this research work is utilizing the color dominance of an image in quantifying the distribution of information in the blue channel and performing enhancement in Lab space followed by a series of steps to optimize overall brightness and contrast. The test set of the Retinal Fundus Multi-disease Image Dataset is used to evaluate the performance of the proposed enhancement technique in identifying the presence or absence of retinal abnormality. The proposed technique achieved an accuracy of 89.53 percent.

Abstract
INTRODUCTION Risk factors for retinal vein occlusion have been extensively studied, with varying population sizes. Smaller populations result in less certain measures of associations. The present review included studies with a relevant population size to identify clinically relevant risk factors for retinal vein occlusion. Understanding the risk factors of retinal vein occlusion is important for the management of these patients. AREAS COVERED A comprehensive literature review was conducted through a systematic literature search in PubMed and Embase. Additional studies were selected from cross references in the assessed studies. Weighted effect measures were calculated for all included risk factors.Risk factors associated with retinal vein occlusion included cardiovascular diseases, eye diseases, systemic diseases, medical interventions, and sociodemographic factors. EXPERT OPINION This review provided an extensive overview of a wide variety of risk factors increasing the risk of developing retinal vein occlusion. The severity of the identified risk factors indicated that these patients have been in contact with the health care system before their retinal vein occlusion event. Therefore, the clinical course for patients with retinal vein occlusion may benefit from a multidisciplinary collaboration between ophthalmologists and especially cardiologists.

Abstract
Retinal vein occlusion (RVO) is the second most prevalent retinal disease. Despite this, the pathogenic mechanisms and risk factors are not entirely clear. In this article, we review recent publications on the classification, pathogenesis, risk factors, ischemic changes, cytokines, and vital complications of RVO. Risk factors and cytokines are important for exploring the mechanisms and new treatment targets. Furthermore, risk factors are interrelated, making RVO mechanisms more complex. Cytokines act as powerful mediators of pathological conditions, such as inflammation, neovascularization, and macular edema. This review aims to summarize the updated knowledge on risk factors, cytokines of RVO and signaling in order to provide valuable insight on managing the disease.

Abstract
PURPOSE To investigate the association between proteinuria and the incidence of retinal vein occlusion (RVO) in individuals with preserved renal function. METHODS We conducted a retrospective cohort study from 2005 to 2020 using the JMDC Claims Database, a large database of health check-ups and administrative claims in Japan. Individuals who underwent annual health check-ups were included. Participants were classified into three groups based on the protein concentration in their urine: negative (≤10 mg/dl), trace (10-30 mg/dl) and positive (≥30 mg/dl). We estimated hazard ratios (HRs) for the development of RVO using Cox regression analyses with adjustment for baseline characteristics by the matching weights calculated from the multiple propensity scores. The cumulative incidence of RVO between the weighted groups was calculated using the Kaplan-Meier estimator. RESULTS There were 1 635 212 eligible participants, among whom 2360 developed RVO. The mean follow-up period was 1036 ± 951 days. The adjusted HRs for RVO were 1.10 (95% confidence interval 0.92-1.33) and 1.46 (1.19-1.78) in the groups with trace and positive proteinuria compared with negative proteinuria respectively. The cumulative incidence rates of RVO at 7 years were 0.40%, 0.43% and 0.55% in the groups with negative, trace and positive proteinuria, respectively. CONCLUSION Positive proteinuria was independently associated with an increased incidence of RVO in individuals with preserved renal function. Proteinuria may be a novel risk factor for RVO development.

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
It has been known that retinal vein occlusion (RVO) is associated with chronic kidney disease, especially end-stage renal disease (ESRD). However, little is known about the effect of kidney transplantation (KT) on RVO incidence in ESRD patients. This study aimed to compare the incidence of RVO in KT recipients (n = 10,498), matched ESRD patients (n = 10,498), and healthy controls (HCs, n = 10,498), using a long-term population-based cohort. The incidence of RVO was 2.74, 5.68, and 1.02 per 1000 patient-years, for the KT group, the ESRD group, and the HCs group, respectively. Adjusted hazard ratios for RVO development compared to the HCs group, were 1.53 and 3.21, in the KT group and the ESRD group, respectively. In the KT group, multivariable regression analysis indicated that an age over 50, a Charlson Comorbidity Index score over 4, and a history of desensitization therapy were associated with an increased risk of RVO. In summary, KT recipients have a lower risk for development of RVO than ESRD patients treated with dialysis. However, the risk is still higher compared to healthy people who have normal kidney functions.

Abstract
PURPOSE To investigate the clinical characteristics and prognostic factors of young patients with central retinal vein occlusion (CRVO). METHODS This retrospective cohort study involved treatment-naïve patients with CRVO. Medical records regarding basic demographics, predisposing factors, ocular characteristics, and treatments were reviewed and compared according to age at CRVO onset. RESULTS We enrolled 263 patients, of whom 69 were younger patients. Younger patients had higher prevalence of nontraditional risk factors including physical or psychological stress (P = 0.032), hematologic abnormalities (P = 0.003), and better visual acuity at baseline and last visit (all P < 0.001) and were unlikely to undergo intravitreal injections (47.8 vs. 68.6%, P < 0.001) during follow-up. Younger patients had higher prevalence of paracentral acute middle maculopathy (28.1 vs. 4.7%, P < 0.001). Older age (odds ratio = 1.165, P = 0.028), male sex (odds ratio = 7.074, P = 0.034), coexisting renal disease (odds ratio = 7.845, P = 0.050), and poor baseline visual acuity (odds ratio = 16.069, P = 0.002) were significant risk factors for poor visual outcomes in young CRVO patients. CONCLUSION Younger CRVO patients had a milder clinical course with fewer treatments and were more likely to have nontraditional risk factors than older patients.

Abstract
The world faces difficulties in terms of eye care, including treatment, quality of prevention, vision rehabilitation services, and scarcity of trained eye care experts. Early detection and diagnosis of ocular pathologies would enable forestall of visual impairment. One challenge that limits the adoption of computer-aided diagnosis tool by ophthalmologists is the number of sight-threatening rare pathologies, such as central retinal artery occlusion or anterior ischemic optic neuropathy, and others are usually ignored. In the past two decades, many publicly available datasets of color fundus images have been collected with a primary focus on diabetic retinopathy, glaucoma, age-related macular degeneration and few other frequent pathologies. To enable development of methods for automatic ocular disease classification of frequent diseases along with the rare pathologies, we have created a new Retinal Fundus Multi-disease Image Dataset (RFMiD). It consists of 3200 fundus images captured using three different fundus cameras with 46 conditions annotated through adjudicated consensus of two senior retinal experts. To the best of our knowledge, our dataset, RFMiD, is the only publicly available dataset that constitutes such a wide variety of diseases that appear in routine clinical settings. This dataset will enable the development of generalizable models for retinal screening.

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.

Abstract
Anterior ischemic optic neuropathy (AION) occurs due to hypoperfusion of the optic nerve and is a rare complication in patients receiving maintenance dialysis. To date, AION has only been reported in 22 children, all of whom were receiving peritoneal dialysis. We report the first case of AION in a 2-year 11-month-old child receiving chronic hemodialysis secondary to polycystic kidney disease from a phosphomannomutase 2 gene mutation. This case highlights the consideration for frequent blood pressure monitoring and ophthalmic screening in a certain cohort of children receiving chronic dialysis.

Abstract
This nationwide retrospective case-control study was aimed at elucidating the risk from cataract surgery in end-stage renal disease (ESRD) patients. Cataract surgery patients were identified using the diagnostic and procedural codes for International Classification of Diseases, 9th Revision, Clinical Modification from Taiwan’s National Health Insurance Research Database. ESRD patients were selected as cases, while propensity scores for age, sex, comorbidities and year-of-surgery-matched patients without chronic kidney disease constituted the controls. Patients who had undergone eye surgery within 3 years before cataract surgery were excluded. The main outcome measures were target cataract surgery-related complications within 3 months after surgery. A total of 352 cases and 1,760 controls were analysed. Patients with ESRD had a 5.06-fold (95% CI: 2.36–10.87; p < 0.001) risk of vitreous haemorrhage and a 2.74-fold (95% CI: 1.20–6.27; p = 0.017) risk of re-operation for dropped nucleus or vitreous complications. Non-diabetic ESRD patients had a 3.49-fold (95% CI: 1.36–8.91; p = 0.009) risk of corneal oedema. In conclusion, ESRD patients have a higher risk of vitreous haemorrhage, re-operation for dropped nucleus or vitreous complications and corneal oedema (non-diabetic patients) after cataract surgery. Pre-surgery corneal examination, surgery procedure and medication adjustment, closer and longer post-surgery follow-up may lower the risk and improve the visual outcome.

[PMID: 31508535 PMCID: PMC6726921 DOI: 10.1016/j.ajoc.2019.100549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Revised: 04/26/2019] [Accepted: 08/26/2019] [Indexed: 10/26/2022] Open
Abstract
PURPOSE In this study, we report a case of branch retinal artery occlusion (BRAO) in the contralateral eye the day after aflibercept treatment during systemic heparin administration. OBSERVATIONS A 63-year-old woman with diabetic macular edema underwent repeated intravitreal injection of anti-VEGF drugs (0.5mg ranibizumab or 2mg aflibercept) for her left eye. The day after intravitreal injection of aflibercept, she presented with sudden painless blurred vision that was limited to the inferior visual field defect in the contralateral eye (right eye) during hemodialysis with the anti-coagulant heparin. Optical coherence tomography angiography (OCTA) showed decreased artery perfusion and the patient was diagnosed with contralateral BRAO. CONCLUSIONS Previous in vitro and in vivo studies have reported that the Fc portion of anti-VEGF drugs activates platelets with heparin. Therefore, careful anti-VEGF drug selection may be necessary in cases with concomitant heparin treatment.

Abstract
Eyes and kidneys have numerous structural, developmental, physiologic, and pathogenic pathways in common, suggesting that many kidney and eye diseases may be interlinked. Studies suggest that the prevalence of eye diseases and vision impairment are higher among persons with end-stage kidney disease and earlier stages of chronic kidney disease (CKD) than in those without. Ocular morbidity in persons with CKD and end-stage kidney disease may be due to the following risk factors: (1) underlying conditions and risk factors for CKD such as diabetes or hypertension, (2) metabolic disorders associated with CKD, (3) uremia and anemia, and (4) CKD treatment. Among the chief eye diseases, diabetic retinopathy and age-related macular degeneration are most consistently associated with CKD. Further research for eye diseases such as glaucoma and cataract is needed to determine their relationships with CKD. Despite the high prevalence and burden of vision impairment among persons with CKD, eye screening in patients with CKD is not currently recommended as standard practice. This review suggests that patients with CKD should be encouraged to undergo a complete eye examination. Furthermore, physicians should be aware that patients undergoing dialysis may develop acute eye problems such as acute glaucoma, and appropriate referral to ophthalmologists should be considered in those with a history of glaucoma or recent ocular surgery. Interdisciplinary collaboration between nephrologists and ophthalmologists will ensure enhanced and appropriate management of patients with CKD.

Chang YS, Weng SF, Chang C, Wang JJ, Chen HI, Ko SY, Tu IT, Chien CC, Wang JJ, Wang CM, Jan RL. Risk of serous retinal detachment in patients with end-stage renal disease on dialysis. PLoS One 2017; 12:e0180133. [PMID: 28658289 PMCID: PMC5489197 DOI: 10.1371/journal.pone.0180133] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Accepted: 06/10/2017] [Indexed: 11/18/2022] Open
Abstract
The aim of this retrospective, nationwide, matched cohort study was to investigate the association of serous retinal detachment with having end-stage renal disease (ESRD) while on dialysis. The cohort study included 94,024 patients with ESRD on dialysis registered between January 2000 to December 2009 in the Taiwan National Health Insurance Research Database. An age- and sex-matched control group comprised 94,024 patients selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. Twenty-seven ESRD patients and 11 controls developed serous retinal detachment (P < 0.001) during follow-up, demonstrating a significantly increased risk of serous retinal detachment in patients with ESRD on dialysis compared with controls (incidence rate ratio = 3.39, 95% confidence interval [CI] = 1.68–6.83). After adjustment for potential confounders, patients were 3.86 times more likely to develop serous retinal detachment than the full cohort (adjusted HR = 3.86, 95% CI = 1.15–12.96). In conclusion, patients with ESRD on dialysis demonstrate an increased risk of serous retinal detachment. Interdisciplinary collaboration between nephrologists and ophthalmologists is important to deal with serous retinal detachment in patients with ESRD on dialysis and prevent impairments of visual acuity.
