Abstract
Purpose We aimed to determine the causal effects of physical activities with different frequencies, durations, and intensities on the risk of senile cataracts using Mendelian randomization (MR). Methods A bidirectional two-sample MR approach was used to determine the association between physical activity and senile cataract risk. Our primary analysis used the inverse variance weighted method, and secondary analyses included MR-Egger regression, MR-PRESSO, and Cochran's Q statistic to evaluate heterogeneity and pleiotropy. Causal estimates were presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). Results Genetically predicted moderate physical activity ≥ 10 min/wk (OR = 0.765, 95% CI = 0.627-0.936, P = 8.73E-03), vigorous physical activity ≥ 10 min/wk (OR = 0.691, 95% CI = 0.521-0.917, P = 1.04E-02), moderate-to-vigorous physical activity levels (OR = 0.552, 95% CI = 0.369-0.823, P = 3.75E-03), and overall acceleration average (OR = 0.952, 95% CI = 0.926-0.978, P = 3.80E-04) were associated with a decreased risk of senile cataract while walking ≥ 10 min/wk (OR = 0.972, 95% CI = 0.741-1.275, P = 8.36E-01) had no significant correlation. The reverse MR analysis showed no reversal causality from senile cataract to physical activity except for walking ≥ 10 min/wk (OR = 0.951, 95% CI = 0.923-0.979, P = 7.30E-04). Conclusions Our findings suggest that moderate to vigorous physical activity with higher frequency and longer duration will causally reduce the risk of senile cataracts, and there is no reverse causal relationship. Translational Relevance These findings underscore the potential of incorporating physical activity into preventive health strategies for senile cataracts.

Abstract
Hypertension, a disease whose prevalence increases with age, induces pathological conditions of ischemic vascular disorders such as cerebral infarction and myocardial infarction due to accelerated arteriosclerosis and circulatory insufficiency of small arteries and sometimes causes hemorrhagic conditions such as cerebral hemorrhage and ruptured aortic aneurysm. On the other hand, as it is said that aging starts with the blood vessels, impaired blood flow associated with vascular aging is the basis for the development of many pathological conditions, and ischemic changes in target organs associated with vascular disorders result in tissue dysfunction and degeneration, inducing organ hypofunction and dysfunction. Therefore, we hypothesized that hypertension is associated with all age-related vascular diseases, and attempted to review the relationship between hypertension and diseases for which a relationship has not been previously well reported. Following our review, we hope that a collaborative effort to unravel age-related diseases from the perspective of hypertension will be undertaken together with experts in various specialties regarding the relationship of hypertension to all pathological conditions.

[PMID: 38304745 PMCID: PMC10831806 DOI: 10.1016/j.eclinm.2024.102424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 12/23/2023] [Accepted: 01/03/2024] [Indexed: 02/03/2024] Open
Abstract
Background Liver disease is linked to series of extrahepatic multisystem manifestations. However, little is known about the associations between liver and eye diseases, especially cataract, the global leading cause of blindness. We aimed to investigate whether severe liver diseases, including non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease (ALD), viral hepatitis, and liver fibrosis and cirrhosis, were associated with an increased risk of the cataract. Methods A total of 326,558 participants without cataract at baseline enrolled in the UK Biobank between 2006 and 2010 were included in this prospective study. The exposures of interest were severe liver diseases (defined as hospital admission), including NAFLD, ALD, viral hepatitis and liver fibrosis and cirrhosis. The outcome was incident cataract. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). Each liver disease was first treated as a binary time-varying variable to investigate its association with cataract, and then was treated as a ternary time-varying variable to examine the recent (liver disease within 0-5 years) vs. long-term (liver disease > 5 years) state associations with the risk of cataract. Findings After a median follow-up of 13.3 years (interquartile range, 12.5-14.0 years), 37,064 individuals were documented as developing cataract. Higher risk of cataract was found in those with severe NAFLD (HR, 1.47; 95% CI, 1.33-1.61), ALD (HR, 1.57; 95% CI, 1.28-1.94) and liver fibrosis and cirrhosis (HR, 1.58; 95% CI, 1.35-1.85), but not in individuals with viral hepatitis when exposure was treated as a binary time-varying variable (P = 0.13). When treating exposure as a ternary time-varying variable, an association between recently diagnosed viral hepatitis and cataract was also observed (HR, 1.55; 95% CI, 1.07-2.23). Results from the combined model suggested they were independent risk factors for incident cataract. No substantial changes were found in further sensitivity analyses. Interpretation Severe liver diseases, including NAFLD, ALD, liver fibrosis and cirrhosis and recently diagnosed viral hepatitis, were associated with cataract. The revelation of liver-eye connection suggests the importance of ophthalmic care in the management of liver disease, and the intervention precedence of patients with liver disease in the early screening and diagnosis of cataract.

Abstract
Objective There are inconsistent findings on the association between obesity and age-related cataract (ARC). This systematic review was done to summarize available findings on the association between obesity [defined by body mass index (BMI)] and ARC by performing a dose-response meta-analysis on eligible prospective cohort studies. Methods We performed a systematic search in PubMed, Scopus, ISI Web of Knowledge, and Google Scholar until June 2022 to identify eligible publications. Results In total, 16 studies with a total sample size of 1,607,125 participants were included. Among all of these studies, there were 103,897 cases of ARC. In the follow-up periods ranging between 4 and 28 years, 4,870 cases of nuclear cataract, 1,611 cases of cortical cataract, and 1,603 cases of posterior subcapsular cataracts (PSC) were detected. By comparing the highest and lowest categories of BMI, we found that higher BMI was associated with an increased risk of ARC (RR: 1.18, 95% CI: 1.09-1.28) and PSC (RR: 1.44, 95% CI: 1.08-1.90). In the dose-response analysis, each 5 kg/m2 increase in BMI was associated with a 6 and 27% increased risk of ARC (RR: 1.06, 95% CI: 1.01-1.12) and PSC (RR: 1.27, 95% CI: 1.14-1.41), respectively. In addition, we found a positive association for cortical cataract among high-quality studies, in which higher BMI was associated with a 20% increased risk of cortical cataract (RR: 1.20, 95% CI: 1.02-1.42). In terms of nuclear cataract, we found no significant association either in the comparison between the highest and lowest categories of BMI or in the dose-response meta-analysis. Conclusion Obesity (defined by BMI) was associated with an increased risk of ARC, PSC, and cortical cataract in adults. However, such a positive association was not seen for nuclear cataract.

Abstract
Background Despite the well-established findings of a higher incidence of retina-related eye diseases in patients with diabetes, there is less investigation into the causal relationship between diabetes and non-retinal eye conditions, such as age-related cataracts and glaucoma. Methods We performed Mendelian randomization (MR) analysis to examine the causal relationship between type 2 diabetes mellitus (T2DM) and 111 ocular diseases. We employed a set of 184 single nucleotide polymorphisms (SNPs) that reached genome-wide significance as instrumental variables (IVs). The primary analysis utilized the inverse variance-weighted (IVW) method, with MR-Egger and weighted median (WM) methods serving as supplementary analyses. Results The results revealed suggestive positive causal relationships between T2DM and various ocular conditions, including "Senile cataract" (OR= 1.07; 95% CI: 1.03, 1.11; P=7.77×10-4), "Glaucoma" (OR= 1.08; 95% CI: 1.02, 1.13; P=4.81×10-3), and "Disorders of optic nerve and visual pathways" (OR= 1.10; 95% CI: 0.99, 1.23; P=7.01×10-2). Conclusion Our evidence supports a causal relationship between T2DM and specific ocular disorders. This provides a basis for further research on the importance of T2DM management and prevention strategies in maintaining ocular health.

Abstract
PRCIS For patients with glaucoma, metabolic syndrome was associated with higher intraocular pressure and greater central corneal thickness. Patients with metabolic syndrome were more likely to have ocular hypertension. PURPOSE The purpose of this study was to determine whether glaucomatous optic neuropathy, also known as glaucoma, and ocular hypertension are more likely to occur in patients with metabolic syndrome. PATIENTS AND METHODS Patients in Olmsted County, MN, were identified as having metabolic syndrome based on diagnosis codes, laboratory values, and/or medication use to meet 3 or more of the 5 standard criteria for diagnosing metabolic syndrome: systemic hypertension, hyperglycemia, hypertriglyceridemia, reduced high-density lipoprotein cholesterol, and central adiposity defined by increased body mass index. Patients with glaucoma, including primary open angle, low tension, pigment dispersion, and pseudoexfoliation, were identified using diagnostic codes. The charts of patients with glaucoma were individually reviewed to collect visual acuity, intraocular pressure, cup to disc ratio, central corneal thickness, visual field mean deviation, retinal nerve fiber layer thickness, and treatment of intraocular pressure. Patients with ocular hypertension were separately identified and similarly evaluated. RESULTS For patients with glaucoma, those with metabolic syndrome had higher intraocular pressure and greater central corneal thickness compared with those without metabolic syndrome. After adjustment for central corneal thickness, there was no longer a significant difference in intraocular pressure between groups. Metabolic syndrome was also associated with the diagnosis of ocular hypertension, and although central corneal thickness trended higher in patients with metabolic syndrome, it did not attain statistical significance. CONCLUSION In Olmsted County, though metabolic syndrome was associated with ocular hypertension and higher intraocular pressure in patients with glaucoma, the results were likely related to a thicker central corneal in this patient population.

Abstract
Cataract is the leading cause of blindness worldwide, and metabolic syndrome (MetS) is a known risk factor. In this study, we investigated the association between the risk of cataract with MetS and its components in a large-scale study. Data were derived from the Taiwan Biobank, and 121,380 individuals were included. The NCEP-ATP III criteria modified for use in an Asian population were used to define MetS and its components. The occurrence of cataract was identified through a standardized interview and self-reported questionnaire. Multivariable analysis showed that MetS (OR, 1.129; 95% CI, 1.0175−1.184; p < 0.001), low high-density lipoprotein (HDL)-cholesterol (OR, 1.057; 95% CI, 1.005−1.113; p = 0.032), and hyperglycemia (OR, 1.162; 95% CI, 1.108−1.218; p < 0.001) were significantly associated with cataract. Furthermore, a stepwise increase in the prevalence of cataract corresponding to the number of MetS components was found. The presence of three MetS components (vs. 0; OR, 1.103; 95% CI, 1.024−1.188; p = 0.010), four MetS components (vs. 0; OR, 1.137; 95% CI, 1.040−1.242; p = 0.005), and five MetS components (vs. 0; OR, 1.208; 95% CI, 1.059−1.378; p = 0.005) were significantly associated with cataract. In conclusion, significant associations were found between a high incidence of cataract with MetS and its components, including low HDL-cholesterolemia and hyperglycemia. Further, a stepwise increase in the prevalence of cataract corresponding to the number of MetS components was also found. The results of this study indicate that MetS may increase the development of cataract in Taiwan.

Abstract
PURPOSE To analyse if patients with diabetic retinopathy (DR) subjected to cataract surgery differ in outcome compared to patients without DR with regard to best-corrected visual acuity (BCVA), deviation from target refraction, intraoperative difficulties and risk of complications. METHODS A register-based study from the Swedish National Cataract Register (NCR) during the years 2015-2017 including 358 040 cataract procedures. Patients with other ocular pathology than cataract and DR were omitted from outcome analyses. RESULTS Diabetic retinopathy was reported in 13 724 of all eyes (3.8%). Preoperative BCVA was significantly worse in DR patients than in patients without DR, 0.54 ± 0.33 compared to 0.40 ± 0.27 (logMAR, mean ± SD, p < 0.001). The same was evident for postoperative BCVA, 0.15 ± 0.25 for DR patients versus 0.06 ± 0.13 (p < 0.001). The improvement in BCVA was slightly better in DR than in non-DR, -0.40 ± 0.32 (logMAR; mean ± SD) versus -0.35 ± 0.27, p < 0.001. The absolute mean biometry prediction error was 0.42 ± 0.50 diopters (D) in DR and 0.43 ± 0.71 D in non-DR patients, p = 0.768. One or more intraoperative difficulties, including mechanical pupil dilation, capsular stain, hooks at capsulorhexis margin or capsular tension ring, had an adjusted odds ratio (OR) of 1.75 (95% confidence interval [CI] 1.61-1.90, p < 0.001) in DR versus non-DR cases and the rate of posterior capsular tears (PCR) had an adjusted OR of 1.76 (95% CI 1.40-2.20, p < 0.001). CONCLUSION Eyes with DR have inferior pre- and postoperative BCVA compared to non-DR eyes. There is little difference in improvement of BCVA and no difference in absolute mean biometry prediction error. Importantly, intraoperative difficulties and PCRs are almost twice as common in DR patients, strongly indicating that these patients should be managed by experienced surgeons.

Yuan S, Wolk A, Larsson SC. Metabolic and lifestyle factors in relation to senile cataract: a Mendelian randomization study. Sci Rep 2022; 12:409. [PMID: 35013517 PMCID: PMC8748724 DOI: 10.1038/s41598-021-04515-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Accepted: 11/30/2021] [Indexed: 12/29/2022] Open
Abstract
We conducted a Mendelian randomization study to determine the associations of body mass index (BMI), type 2 diabetes (T2D), systolic blood pressure (SBP), coffee and alcohol consumption and smoking initiation with senile cataract. Independent single nucleotide polymorphisms associated with the metabolic and lifestyle factors at the p < 5 × 10-8 were selected as instrument variables. Summary-level data for senile cataract were obtained from the FinnGen consortium (20,157 cases and 154,905 non-cases) and UK Biobank study (6332 cases and 354,862 non-cases). Higher genetically predicted BMI and SBP and genetic predisposition to T2D and smoking initiation were associated with an increased risk of senile cataract. The combined odds ratios were 1.19 (95% confidence interval (CI) 1.09-1.29; p < 0.001) per one standard deviation increase in BMI (~ 4.8 kg/m2), 1.13 (95% CI 1.04-1.23; p = 0.004) per 10 mmHg increase in SBP, 1.06 (95% CI 1.03-1.09; p < 0.001) per one unit increase in log-transformed odds ratio of T2D, and 1.19 (95% CI 1.10-1.29; p < 0.001) per one standard deviation increase in prevalence of smoking initiation. Genetically predicted coffee consumption showed a suggestive association with senile cataract (odds ratio per 50% increase, 1.18, 95% CI 1.00-1.40; p = 0.050). This study suggests causal roles of obesity, T2D, SBP and smoking in senile cataract.

Abstract
Background Body mass index (BMI) has been reported to be associated with age-related cataract, whereas its impact on early onset cataract (EOC) remains unknown. Methods A total of 73,007 individuals aged 45–55 years who had no previous cataract surgeries at baseline were enrolled from the population-based 45 and Up Study. BMI was calculated based on self-reported height and weight from the baseline questionnaire. Data on cataract surgeries were obtained from the Medicare Benefits Schedule database. EOC was defined as cataract surgically treated prior to 65 years of age. A Cox proportional hazards regression was used to assess the association between BMI and the incidence of EOC during the follow-up. Results A total of 1,764 participants underwent cataract surgery over 643,717 person-years of follow-up. No significant association was observed between BMI and EOC (P for trend 0.35). Among participants who drank 5 to 7 alcoholic drinks per week, a 73% and 27% reduction in the risk of EOC was observed in participants with a BMI of 18.5–19.99 and 25.0–27.49 kg/m2, respectively, compared to those with a BMI of 20.0–22.49 kg/m2. Conclusions No association was identified between BMI and the incidence of EOC. Moderate alcohol intake may be protective against EOC.

Abstract
Purpose To examine the association between adiposity by differing measures and incident cataract and identify important factors contributing to the association. Methods Our analysis included 153,139 adults from the UK Biobank, aged 40 to 70 years at baseline (2006-2010). Cataract was ascertained using hospital inpatient, and self-reported data until the early of 2021. Anthropometric measures, body fat percentage, and glycosylated hemoglobin (HbA1c) were measured at baseline. Results During a median follow-up of 10.9 years, 15,255 cases of incident cataract were documented. HbA1c was an important contributor to the association between obesity and incident cataract. Obesity; defined by body mass index was associated with an increased risk of cataract (hazard ratio [HR], 1.21 95% confidence interval [CI], 1.16-1.26), and this association was attenuated but remained significant after additional adjustment for HbA1c (HR, 1.05; 95% CI, 1.00-1.10). Similar results were observed for obesity defined by waist circumference or waist-to-hip ratio. Obesity defined by fat percentage was associated with an increased risk of cataract before but not after adjustment for covariates. The association between obesity defined by body mass index and incident cataract was positively significant in individuals with normal HbA1c (HR, 1.07; 95% CI, 1.02-1.13), but inversely significant in those with prediabetes (HR, 0.80; 95% CI, 0.67-0.96) or diabetes (HR, 0.74; 95% CI, 0.61-0.89). Conclusions Anthropometric measurements are more predictive of cataract than bioelectrical impedance measures. Diabetes plays an important role in the association between obesity and incident cataract.

Abstract
BACKGROUND Obesity is a public health challenge worldwide. The relationship between obesity and age-related eye diseases including cataract, glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy (DR) have remained elusive. DESIGN AND METHODS We conducted a systematic review of three electronic databases for longitudinal population-based studies that described associations between measures of obesity including body mass index (BMI), waist-circumference (WC), and waist-to-hip ratio (WHR), and age-related eye diseases. RESULTS Our search yielded 1731 articles, of which 14, 10, 16 and 8 articles met our eligibility criteria for cataract, glaucoma, AMD and DR, respectively. BMI-defined obesity was positively associated with incident cataract, incident AMD and incident DR in Western populations, but in Asian populations associations for incident AMD were not significant and associations for incident DR were inverse. WC-defined obesity was associated with incident glaucoma in non-Western populations. WHR-defined obesity but not BMI-defined obesity was associated with the incidence or progression of AMD in two Western studies. CONCLUSIONS Overall, we found strong evidence supporting associations between obesity and age-related eye diseases. Further research on the association of abdominal obesity and effect of weight loss and physical activity on age-related eye diseases is warranted to support clinical and public health recommendations.

Abstract
PURPOSE To identify risk factors associated with lens opacities in Chinese Americans. METHODS A cross-sectional population-based study of 4,582 Chinese Americans ≥50 years residing in Monterey Park, California. Participants completed a comprehensive clinical examination with lens assessment using the Lens Opacities Classification System II, with lens opacities defined by a grade ≥2 in either eye. Participants were considered to have nuclear-only, cortical-only, or posterior subcapsular (PSC)-only if that was the only type of opacity present in both eyes. RESULTS Cortical-only opacity was associated with older age, diabetes mellitus (OR 1.5, 95%CI 1.1-2.1), and family history of cataracts (OR 1.5, 95%CI 1.2-1.9). Nuclear-only opacity was associated with older age, diabetes mellitus (OR 1.4, 95%CI 1.1-1.9), greater waist-to-hip ratio (OR 1.2, 95%CI 1.1-1.4), and high-density lipoprotein (OR 1.1, 95%CI 1.02-1.2). Mixed-type opacities were associated with older age, greater waist-to-hip ratio (OR 1.3, 95%CI 1.1-1.6), and higher HbA1 c (OR 1.3, 95%CI 1.1-1.4). Taller height (OR 0.7, 95%CI 0.6-0.8), greater weight (OR 0.98, 95%CI 0.97-0.99), and higher diastolic pressure (OR 0.98, 95%CI 0.96-0.99) were protective. CONCLUSION CHES identified a strong, dose-response association between age and all types of prevalent lens opacities, which suggests an increasing cataract burden in Chinese Americans based on aging populations. CHES results demonstrate general consistency with previous population-based studies in regard to more sedentary lifestyle exposures (e.g., Westernized lifestyle) and prevalent cortical-only, nuclear-only, and mixed-type opacities, yet also identified further sedentary lifestyle exposures associated with prevalent lens opacities. Improved glycemic control and a more active lifestyle that minimizes factors contributing to metabolic syndrome may help reduce the burden of vision loss associated with lens opacities.

Abstract
Metabolic syndrome (MetS) has emerged as a worldwide health hazard of the modern lifestyle, representing a cluster of metabolic abnormalities and a risk factor for cardiovascular disease. Eye diseases, such as diabetic retinopathy, central retinal artery occlusion, cataract, age-related macular degeneration, glaucoma, and dry eye syndrome have been linked with many of MetS components. Their relationship with MetS itself is, however, a recent topic of investigation. This review aims to gather published evidence supporting associations between ocular findings and MetS and to explore the related physiopathological processes that congregate in this syndrome and lead to these diseases. Despite compiling interesting and compelling evidence, it raises awareness to the need of further studies in this field to keep solidifying these associations and unveiling the pathological processes that support them. It ultimately targets MetS patients as a population of individuals who are at increased risk of developing age-related eye diseases and vision loss.

Abstract
AIM To summarize quantitatively the prospective association between physical activity and age-related cataract (ARC) risk. METHODS PubMed, Embase, Web of Science, and Cochrane Library were systematically searched for all relevant follow up studies until July 2019. Multivariable-adjusted relative risks (RRs) and corresponding 95% confidence intervals (CIs) from individual studies were used to calculate the overall summary estimates. The dose-response relationship was assessed using generalized least-squares trend estimation. RESULTS Six prospective cohort studies, involving 19 173 cases in 6.2-12.1y follow up of 171 620 participants, were included in the analysis. Increased physical activity was significantly associated with reduced risk of ARC by 10% (RR: 0.90; 95%CI: 0.81, 0.99, P=0.04). Stratified analysis by assessment method for physical activity suggest that studies using metabolic equivalent (MET) per day tended to report a slightly stronger association with ARC (RR: 0.85; 95%CI: 0.81, 0.90, P<0.001) than studies which assessed activity by weekly activity (RR: 0.96; 95%CI: 0.89, 1.03, P=0.24). Dose-response analysis indicated that the risk of ARC decreased by 2% (RR: 0.98; 95%CI: 0.98, 0.99, P<0.001) for every 6 METs per day increase in activity. CONCLUSION The findings from this Meta-analysis provide additional evidence that increased physical activity is inversely associated with ARC risk dose-responsively.

Abstract
PURPOSE To investigate effect of metabolic syndrome on blood pressure during cataract surgery with topical anesthesia. DESIGN A single-centered, retrospective case series. METHODS Consecutive patients who were hospitalized and underwent phacoemulsification and insertion of intraocular lens with topical anesthesia in October 2016 were included. Perioperative blood pressure and pulse pressure were compared between patients with metabolic syndrome (metabolic group) and sex- and age-matched patients without metabolic syndrome (nonmetabolic group) at six time points: on admission, in the morning of the operation, 2 hours before the operation, at the point of entering the operation room, during the operation, and after the operation. Perioperative use of etizolam and nicardipine was compared between the two groups. RESULTS Thirty patients in the metabolic group and 30 in the nonmetabolic group were included. There was no difference in changes compared with the values on admission in systolic pressure and pulse pressure at any examination point between the two groups. There was no difference in changes in diastolic pressure between the two groups, except for at 2 hours before the operation (1.4 ± 9.6 mm Hg in the metabolic group vs -6.2 ± 8.5 mm Hg in the nonmetabolic group; P = 0.044). The number of patients who were administered etizolam was 5/30 (16.7%) in the metabolic group and 2/30 (6.7%) in the nonmetabolic group, showing no significant difference. No patients were administered intravenous nicardipine in either group. CONCLUSIONS Well-controlled metabolic syndrome did not affect the changes in perioperative blood pressure during cataract surgery with topical anesthesia.

Abstract
BACKGROUND The relationship between gout medication use and cataract development is controversial. Moreover, limited clinical studies have evaluated this relationship. AIM To assess the effects of colchicine, allopurinol and benzbromarone on the risk of cataract in patients with gout. DESIGN Population-based nested case-control study. METHODS We enrolled 7900 patients who had received a new diagnosis of cataract >3 years after gout diagnosis into the study group and 33 475 patients who did not receive a diagnosis of cataract into the control group by matching for age, sex and the year of gout diagnosis at a ratio of 1:1. We used World Health Organization's defined daily dose (DDD) as a measure to assess the dosage of colchicine, allopurinol and benzbromarone exposure. Logistic regression was used to estimate crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of cataract. RESULTS The risk of cataract significantly increased in patients who received colchicine at a cumulative DDD of ≥66.5 (OR = 1.17, 95% CI = 1.01-1.36, P = 0.041). In the age-stratified analysis, patients with gout aged >60 years had a higher risk of cataract (OR = 1.27, 95% CI = 1.06-1.53, P = 0.011) than did patients aged <60 years. Allopurinol and benzbromarone had no association with cataract. CONCLUSIONS In this population-based nested case-control study, we observed that colchicine use increased the risk of cataract in patients with gout, especially in those aged >60 years who received colchicine at a cumulative DDD of >66.5.

Schizophr Res 2019; 212:150-156. [PMID: 31395489 DOI: 10.1016/j.schres.2019.07.049] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2018] [Revised: 03/04/2019] [Accepted: 07/28/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Long-term cataract risks associated with first-generation antipsychotics (FGAs) and second-generation antipsychotics (SGAs), and their associations with metabolism-related diseases are not yet elucidated. METHODS Using Taiwan National Health Insurance data, we conducted a propensity score matched population-based cohort study consisting of 10,014 patients with newly diagnosed schizophrenia from 2005 to 2009 and followed them until the end of 2013. A Cox hazard model with metabolism-related diseases as time-dependent covariates was adapted to estimate the hazard ratio (HR) of cataracts between SGAs and FGAs groups. RESULTS During the 8-year follow-up, patients receiving SGAs were associated with a higher risk of cataract than those receiving FGAs with an adjusted HR of 1.59 (95% confidence interval [CI] = 1.06-2.36). Patients receiving high-metabolic-risk SGAs (clozapine and olanzapine) showed the highest risk of cataracts among SGAs when compared with those receiving FGAs (aHR = 2.57, 95% CI: 1.35-4.88). SGAs demonstrated a stronger contribution in the risk of cataract in patients without diabetes mellitus (DM) and hyperlipidemia than in those developed these diseases. Patients who developed DM or hyperlipidemia after receiving antipsychotics had an approximately 2.5-fold increased cataract risk over those who did not develop these diseases. CONCLUSIONS Regardless of the condition of metabolic-related diseases, SGAs were independently associated with an increased risk of cataract. DM and hyperlipidemia developed after antipsychotics contributed to the risk of cataract risk.

Abstract
BACKGROUND Decreased light reception because of cataracts leads to potential circadian misalignment, resulting in exacerbation of atherosclerosis; however, little is known about the association between cataracts and atherosclerosis in populations.Methods and Results:In this cross-sectional study, cataracts were graded using slit lamp biomicroscopy with the Lens Opacities Classification System III and carotid atherosclerosis was assessed based on carotid intima-media thickness (IMT) measured using ultrasonography of the common carotid artery in 442 elderly participants (mean age, 70.0 years). Cataract was defined as nuclear cataract grade ≥3.0, cortical cataract grade ≥2.0, or posterior subcapsular cataract grade ≥2.0 in both eyes. The mean and maximal carotid IMT was 0.86±0.15 mm and 1.07±0.29 mm, respectively. In multivariable analysis adjusted for potential confounders, the mean and maximal carotid IMT were significantly greater in the cataract group than in the non-cataract group by 0.04 mm (95% confidence interval (CI), 0.01-0.06) and 0.07 mm (95% CI, 0.01-0.12), respectively. Logistic regression analysis adjusted for confounders revealed a significantly higher odds ratio for carotid atherosclerosis (maximal carotid IMT ≥1.1 mm) in the cataract group than in the non-cataract group (odds ratio, 1.78; 95% CI, 1.14-2.78). CONCLUSIONS Cataracts may be independently associated with subclinical carotid atherosclerosis in the elderly population, indicating a need for further prospective studies.

Abstract
PURPOSE To evaluate the relationship between metabolic syndrome and some of its components with the incidence of cataract extraction. METHODS A population-based prospective cohort with a total of 45 049 men, aged 45-79 years, from the Cohort of Swedish Men completed in 1997 a self-administered questionnaire concerning anthropometric measurements and lifestyle factors. The men were followed from 1 January 1998 through 31 December 2012, and the cohort was matched with registers of cataract extraction. The main outcome measure was incident cases of age-related cataract extraction. RESULTS Over the 15-years of follow-up, 7573 incident cases of cataract extraction were identified. After controlling for potential confounders, the association between single components of metabolic syndrome, abdominal adiposity, diabetes and hypertension and risk of cataract extraction was rate ratio (RR): 1.04; 95% confidence interval (CI): 0.99-1.10, RR: 1.77; 95% CI: 1.64-1.92 and RR: 1.06; 95% CI 1.00-1.13, respectively. The risk of cataract extraction increased with increasing numbers of metabolic syndrome components (p < 0.0001). Men aged 65 years or younger at baseline with all three components of the metabolic syndrome had a relative risk of 2.43 (95% CI: 1.95-3.01) for cataract extraction. CONCLUSION In this cohort of middle-aged and elderly men, metabolic syndrome with the combination of abdominal adiposity, diabetes and hypertension was associated with an increased risk for cataract extraction, especially among men aged 65 years or younger. These findings put emphasis on the importance of weight control and healthy lifestyle behaviours in order to prevent cataract.

Abstract
Cigarette smoking increases the risk of developing both cataract and chronic obstructive pulmonary disease (COPD). The prevalence of cataract and the clinical characteristics of COPD patients with cataract were retrospectively investigated in a 2-year observational COPD cohort. We analyzed 395 patients with complete data on ophthalmologic evaluation (319 subjects with COPD and 76 subjects at risk of COPD). There was no difference in the prevalence of cataract between COPD patients and those at risk (47.0% vs. 42.1%, p = 0.44). Age ≥ 75 years, low body mass index, and hypertension were independently associated with cataract as a comorbidity in COPD. The incidence of exacerbation within 2 years was significantly higher in COPD patients with cataract than those without cataract (36.6% vs. 18.3%, p = 0.0019). COPD patients with cataract exhibited significantly higher COPD assessment test score compared to those without cataract (13.7 ± 8.9 vs. 11.5 ± 7.2, p = 0.0240). Overall St George's Respiratory Questionnaire score and each component were significantly worse in COPD patients with cataract compared to those without cataract. COPD patients with cataract exhibited poor health-related quality of life and frequent exacerbations. The association between cataract and exacerbations of COPD deserves further attention.

Abstract
Purpose: To study epidemiology and clinical findings of cataract in HIV+ patients. Methods: A total of 32 HIV+ patients, 11 with uveitis/retinitis before surgery and 21 without, mean follow-up 44.9 ± 36.6 months, and 114 HIV- patients, 57 with uveitis/retinitis before surgery and 57 without, were retrospectively compared. Results: Visual acuity improved in all HIV+ patients (p < 0.001), who were younger (p = 0.01) and more frequently males (p = 0.027). HIV+ patients with uveitis prior surgery improved less (p = 0.046) than HIV- (p < 0.001); their anterior chamber inflammation was similar to baseline. Male sex (p = 0.005), younger age (p < 0.001), dyslipidaemia (p = 0.058), HBV+ (p = 0.037), and unilateral cataract (p = 0.001) were more frequent in HIV+ patients with senile cataract, but they showed the same postoperative course as HIV- patients. Conclusion: Cataract surgery in HIV+ patients is safe and effective. Uveitis prior to surgery did not significantly affect the postoperative course. Systemic comorbidities are more frequent in HIV+ patients with senile cataract than in HIV- subjects.

Abstract
The purpose of this study is to track the trends of low visual acuity (VA) from 2005 to 2014, and to investigate its associations with systemic blood pressure (BP) components among adolescents in Northeast China. A total of 55320 students of Han nationality aged 13 to 18 years were included. There has been a significant increase in the prevalence of low VA, with 31.3% in 2005, 40.2% in 2010 and 43.4% in 2014. In multivariable-adjusted logistic regression models, each 1-mm Hg increment in systolic BP (SBP) was associated with 0.8% (95% confidence interval [CI]: 0.1–1.6%), 0.5% (95% CI: 0.1–0.9%) and 1.1% (95% CI: 0.6–1.6%) increased odds of low VA for males in 2005, 2010 and 2014; each 1-mm Hg increment in pulse pressure (PP) was associated with 1.6% (95% CI: 0.7–2.5%), 0.8% (95% CI: 0.4–1.2%) and 1.2% (95% CI: 0.7–1.7%) increased odds of low VA. Higher PP categories had greater odds for low VA compared with the reference group. Similar associations were not observed for females. We conclude that higher prevalence of low VA was significantly associated with higher SBP and PP in males. Furthermore, there was a dose-dependent association between the prevalence of low VA and the levels of PP.

Abstract
AIMS We assessed the long-term risk of cataract following a pregnancy complicated by gestational diabetes. METHODS We carried out a longitudinal cohort study of 1,108,541 women who delivered infants between 1989-2013 in Quebec, Canada, with follow-up extending up to 25years later. The cohort included 71,862 women with gestational diabetes and 5247 with cataracts. We used Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of gestational diabetes with subsequent risk of cataract, adjusted for age, parity, socioeconomic status, time period, comorbidity, and type 2 diabetes. RESULTS Women with gestational diabetes had an elevated incidence of cataract (22.6 per 1000) compared with no gestational diabetes (15.1 per 1000), with 1.15 times the risk (95% CI 1.04-1.28). Women with gestational diabetes who subsequently developed type 2 diabetes had a higher risk of cataract compared with no gestational and type 2 diabetes (HR 3.62, 95% CI 3.01-4.35), but women with gestational diabetes who did not develop type 2 diabetes continued to be at risk (HR 1.12, 95% CI 1.00-1.25). CONCLUSIONS Gestational diabetes may be an independent risk factor for cataract later in life, although risks are greatest for women who subsequently develop type 2 diabetes.

Abstract
Background This study sought to identify multimorbidity patterns and determine the association between these latent classes with several outcomes, including health, functioning, disability, quality of life and use of services, at baseline and after 3 years of follow-up. Methods We analyzed data from a representative Spanish cohort of 3541 non-institutionalized people aged 50 years old and over. Measures were taken at baseline and after 3 years of follow-up. Latent Class Analysis (LCA) was conducted using eleven common chronic conditions. Generalized linear models were conducted to determine the adjusted association of multimorbidity latent classes with several outcomes. Results 63.8% of participants were assigned to the “healthy” class, with minimum disease, 30% were classified under the “metabolic/stroke” class and 6% were assigned to the “cardiorespiratory/mental/arthritis” class. Significant cross-sectional associations were found between membership of both multimorbidity classes and poorer memory, quality of life, greater burden and more use of services. After 3 years of follow-up, the “metabolic/stroke” class was a significant predictor of lower levels of verbal fluency while the two multimorbidity classes predicted poor quality of life, problems in independent living, higher risk of hospitalization and greater use of health services. Conclusions Common chronic conditions in older people cluster together in broad categories. These broad clusters are qualitatively distinct and are important predictors of several health and functioning outcomes. Future studies are needed to understand underlying mechanisms and common risk factors for patterns of multimorbidity and to propose more effective treatments.

Abstract
This study was attempted to address the association between early onset cataract (EOC) and ischemic stroke. Using the Longitudinal Health Insurance Database 2000, we established an EOC cohort and a comparison cohort by using 4-fold propensity score matching according to age, gender and comorbidities to detect the incidence of ischemic stroke. A Cox model was used to express the risk of ischemic stroke for the EOC patients compared with the comparison cohort. After adjusting for age, gender and comorbidities of hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, asthma, chronic obstructive pulmonary disease, chronic kidney disease, heart failure, obesity, and atrial fibrillation, the EOC patients had a 1.48-fold higher risk of ischemic stroke than the comparison cohort, but it was not statistically significant. A non-significant increase in the risk of subsequent ischemic stroke development for the EOC patients is demonstrated in this study.

[PMID: 27899314 DOI: 10.1016/j.ajog.2016.11.1043] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2016] [Revised: 11/15/2016] [Accepted: 11/21/2016] [Indexed: 11/18/2022]
Abstract
BACKGROUND Pregnancy-related risk factors for cataract are understudied, including the possibility that preeclampsia increases the risk of cataract later in life. OBJECTIVE We sought to evaluate the long-term risk of cataract extraction following a preeclamptic pregnancy. STUDY DESIGN We carried out a historic cohort study of 1,108,541 women who delivered at least 1 infant in any hospital in the province of Quebec, Canada, from 1989 through 2013, including 64,350 with preeclampsia and 5732 with cataract extractions. We categorized preeclampsia by onset time and severity, and followed up women for up to 25 years after delivery. We calculated the incidence of inpatient cataract extraction for women with and without preeclampsia, and used Cox proportional hazard models to estimate hazard ratios and 95% confidence intervals for later risk of cataract extraction, adjusting for age at first delivery, total parity, metabolic disease, asthma, socioeconomic deprivation, and time period. RESULTS Women with preeclampsia had a higher incidence of cataract extraction compared with no preeclampsia (21.0 vs 15.9/1000) and 1.20 times the risk (95% confidence interval, 1.08-1.34). Women with early-onset preeclampsia had 1.51 times the risk of cataract extraction compared with no preeclampsia (95% confidence interval, 1.14-2.00), whereas women with late-onset preeclampsia had 1.16 times the risk (95% confidence interval, 1.04-1.30). Risk was elevated by about 20% for both severe and mild preeclampsia. Preeclampsia with diabetes was associated with significantly greater risk (hazard ratio, 4.32; 95% confidence interval, 3.60-5.19). CONCLUSION Women with preeclampsia, particularly preeclampsia of early onset or with diabetes, may have greater risk of cataract later in life. The underlying pathways linking preeclampsia with cataract require further investigation.

Abstract
OBJECTIVE To identify the association between cataract and the subsequent atrial fibrillation (AF) risk. PATIENTS AND METHODS Our retrospective cohort study was designed to analyze the Longitudinal Health Insurance Database 2000 of the Taiwan National Health Insurance program. We established a cataract cohort (n=39,347) and a noncataract cohort (n=39,347) to observe the incidence of AF. The cataract cohort included patients who were newly diagnosed with cataract from January 1, 2000, to December 31, 2010. Propensity score matching was used to form matched sets of participants with cataract and participants without cataract who share a similar value of propensity score. Univariable and multivariable Cox proportional hazards regression models were used to assess the association between having a cataract and AF. RESULTS The median (range) follow-up period was 6.52 years (range, 3.76-9.19 years) and 5.88 years (range, 3.12-8.66 years) for the cataract and noncataract cohorts, respectively; the cumulative incidence curves of AF indicated that the cataract cohort had a significantly higher risk of developing AF than did the noncataract cohort (P<.001). Moreover, the risk of AF was 1.32-fold (95% CI, 1.18-1.48) higher in patients with cataract with surgery and was 1.21-fold (95% CI, 1.06-1.37) higher in patients with cataract without surgery than in patients without cataract. CONCLUSION The present study is the first to report that cataract is associated with an increased risk of AF.

Abstract
BACKGROUND Association between cataract and the risk of ischemic heart disease (IHD) development is not completely clear. PURPOSE The primary aim of the study was to evaluate the association between cataract and the risk of incident IHD. The secondary aim was to investigate the subsequent IHD risk of patients with cataracts undergoing cataract surgery. METHODS Retrospective data from the Longitudinal Health Insurance Database 2000 (LHID2000) was analyzed. Study participants were composed of patients with cataracts (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] code 366) (n = 32,456), and a comparison cohort without the cataracts (n = 32,456) from 2000 to 2010. Cox proportional hazards regression was used to address the hazard ratio (HR) of IHD associated with cataract. RESULTS Within 12 years of follow up, the overall incidence rates of IHD were 24.2 per 1000 person-years in the cataract cohort and 18.2 per 1000 person-years in the noncataract cohort with an adjusted hazard ratio (aHR) of 1.35 (95% CI = 1.29-1.41; P < 0.001). Furthermore, the cataract patients undergoing cataract surgery were associated with a higher risk of IHD compared with those cataract patients without surgery (aHR = 1.07, 95% CI: 1.01-1.14; P < 0.05). CONCLUSIONS Our finding suggested that patients with cataracts are at an increased risk of subsequent IHD development.

Abstract
PURPOSE We conducted this study to evaluate the risk of peripheral artery occlusive disease (PAOD) among patients with cataracts. METHODS We analyzed the data from Taiwan National Health Insurance Research Database. Study participants were classified into the cataract group and the non-cataract group between 2000 and 2010. All patients were observed from the index year until PAOD diagnosis, loss to follow up, or the end of 2011. Both study groups were 1:1 matching based upon a propensity score. We used a cox proportional hazards regression model to assess the hazard ratio (HR) and 95% confidence interval (CI) of PAOD for the cataract cohort compared with the non-cataract cohort. RESULTS After adjustment for age, sex and comorbidities, the risk of PAOD was significantly higher in the cataract cohort [adjusted HR (aHR)=1.48, 95% CI=1.38-1.58] than the non-cataract cohort. CONCLUSIONS We found that patients with cataracts had a 1.48-fold increased risk of developing PAOD compared to the non-cataract patients.

Abstract
Metabolic syndrome is becoming a worldwide medical and public health challenge as it has been seen increasing in prevalence over the years. Age-related eye diseases, the leading cause of blindness globally and visual impairment in developed countries, are also on the rise due to aging of the population. Many of the individual components of the metabolic syndrome have been shown to be associated with these eye diseases. However, the association of metabolic syndrome with eye diseases is not clear. In this review, we reviewed the evidence for associations between metabolic syndrome and certain ocular diseases in populations. We also reviewed the association of individual metabolic syndrome components with ocular diseases due to a paucity of research in this area. Besides, we also summarised the current understanding of etiological mechanisms of how metabolic syndrome or the individual components lead to these ocular diseases. With increasing evidence of such associations, it may be important to identify patients who are at risk of developing metabolic syndrome as prompt treatment and intervention may potentially decrease the risk of developing certain ocular diseases.

Abstract
OBJECTIVE To investigate whether routine eye screening by an ophthalmologist in patients with HIV-1 infection is clinically useful. METHODS A single-center, retrospective study in Tokyo, Japan. HIV-1-infected patients aged over 17 years who visited our clinic for the first time between January 2004 and December 2013 and underwent full ophthalmologic examination were enrolled. At our clinic, ophthalmologic examination, including dilated retinal examination by indirect ophthalmoscopy was routinely conducted by ophthalmologists on the first visit. The prevalence of ophthalmologic diseases and associated factors including the existence of ocular symptoms were analyzed. RESULTS Of the 1,515 study patients, cytomegalovirus retinitis (CMV-R) was diagnosed in 24 (2%) patients, HIV retinopathy (HIV-R) in 127 (8%), cataract in 31 (2%), ocular syphilis in 4 (0.3%), and uveitis with unknown cause in 8 (0.5%). Other ocular diseases were diagnosed in 14 patients. The CD4 count was <200 /μL in all CMV-R cases and 87% of HIV-R. The prevalence of any ocular diseases, CMV-R, and HIV-R in patients with CD4 <200 /μL were 22%, 3%, and 15%, respectively, whereas for those with CD4 ≥200 /μL were 5%, 0%, and 2%, respectively. No ocular symptoms were reported by 71% of CMV-R cases and 82% of patients with any ocular diseases. CONCLUSIONS Routine ophthalmologic screening is recommended for HIV-1-infected patients with CD4 <200 /μL in resource-rich settings based on the high prevalence of ocular diseases within this CD4 count category and because most patients with ocular diseases, including those with CMV-R, were free of ocular symptoms.

Abstract
AIM To determine the effect of metabolic syndrome on age-related cataract formation. METHODS We analyzed data for 2852 subjects [41.8% men and 58.2% women; mean (±SD) age, 52.9±13.9y], taken from the Korea National Health and Nutrition Examination Survey 2008. Metabolic syndrome was diagnosed by criteria proposed by the Joint Interim Societies. Cataract was diagnosed by using the Lens Opacities Classification System III. The association between metabolic syndrome and cataract was determined using age-adjusted and multivariable logistic regression analyses. RESULTS In multivariable analyses, men with metabolic syndrome had a 64% increased risk of nuclear cataract [odds ratio (OR), 1.64; 95% confidence interval (CI), 1.12-2.39]. Women with metabolic syndrome had a 56% increased risk of cortical cataract (OR, 1.56; 95% CI, 1.06-2.30). Men and women with metabolic syndrome had a 46% (OR, 1.46; 95% CI, 1.01-2.12) and 49% (OR, 1.49; 95% CI, 1.07-2.08) increased risk of any cataract, respectively. The prevalence of nuclear and any cataract significantly increased with an increasing number of disturbed metabolic components in men, and prevalence of all types of cataracts increased in women. Men using hypoglycemic medication had an increased risk of nuclear (OR, 2.62; 95% CI, 1.41-4.86) and any (OR, 2.27; 95% CI, 1.14-4.51) cataract, and women using antidyslipidemia medication had an increased risk of cortical (OR, 2.18; 95% CI, 1.12-4.24) and any (OR, 2.21; 95% CI, 1.14-4.26) cataract. CONCLUSION Metabolic syndrome and its components, such as abdominal obesity, high blood pressure, and impaired fasting glucose, are associated with age-related cataract formation in the Korean population.

Abstract
The aim of this study was to investigate the association of central and abdominal obesity with the prevalence of cataracts in a middle-aged Korean population. This retrospective cross-sectional study was based on the data collected from the Korea National Health and Nutrition Examination Survey 2008–2009, in which 4,914 subjects were examined. Ophthalmological examinations were performed to determine the presence of a nuclear, cortical, or posterior subcapsular cataract. Both general obesity (a body mass index ≥25 kg/m2) and abdominal obesity (a waist circumference ≥90 cm for men and ≥80 cm for women) were significantly associated with the occurrence of cataracts among middle-aged women [adjusted odds ratio (aOR), 1.32; 95% confidence interval (CI), 1.03–1.69; and aOR, 1.40; 95% CI, 1.06–1.85, respectively], while abdominal obesity was significantly inversely associated with the occurrence of cataracts among middle-aged men (aOR, 0.76; 95% CI, 0.58–1.01; and aOR, 0.66; 95% CI, 0.49–0.89, respectively). We report a difference in the association between obesity and the prevalence of cataracts based on gender.

Abstract
Background Cataract is the major cause of blindness across the world. Many epidemiologic studies indicated that hypertension might play an important role in the development of cataract, while others not. We therefore conducted this meta-analysis to determine the relationship between risk of cataract and hypertension. Methods Retrieved studies on the association of hypertension with cataract risk were collected from PubMed, Web of Science and the Cochrane Library during June 2014 and were included into the final analysis according to the definite inclusion criteria. Odds ratio (OR) or risk ratio (RR) were pooled with 95% confidence interval (CI) to evaluate the relationship between hypertension and cataract risk. Subgroup analyses were carried out on the basis of cataract type, race and whether studies were adjusted for main components of metabolic syndrome (MS). Results The final meta-analysis included 25 studies (9 cohort, 5 case-control and 11 cross-sectional) from 23 articles. The pooled results showed that cataract risk in populations with hypertension significantly increased among cohort studies (RR 1.08; 95% CI: 1.05–1.12) and case-control or cross-sectional studies (OR 1.28; 95% CI: 1.12–1.45). This association was proved to be true among both Mongolians and Caucasians, and the significance was not altered by the adjustment of main components of MS. Subgroup analysis on cataract types indicated that an increased incidence of posterior subcapsular cataract (PSC) resulted among cohort studies (RR 1.22; 95% CI: 1.03–1.46) and cross-sectional/case-control studies (OR 1.23; 95% CI: 1.09–1.39). No association of hypertension with risk of nuclear cataract was found. Conclusions The present meta-analysis suggests that hypertension increases the risk of cataract, especially PSC. Further efforts should be made to explore the potential biological mechanisms.

Abstract
OBJECTIVE To examine the association of total and specific types of physical activity, including walking or bicycling, exercising, work or occupational activity, home or housework, and leisure time inactivity with the risk of age-related cataract in women and men. DESIGN Population-based prospective cohort study. PARTICIPANTS A total of 52 660 participants (23 853 women and 28 807 men) 45 to 83 years of age from the Swedish Mammography Cohort and the Cohort of Swedish Men. METHODS Physical activity was assessed using a self-administered questionnaire at baseline. Cataract diagnosis and extraction were identified through linkage to registers. MAIN OUTCOME MEASURES Incident age-related cataract diagnosis and cataract extraction. RESULTS During a mean 12.1 years of follow-up (between January 1, 1998, and December 31, 2011; 634 631 person-years), 11 580 incident age-related cataract cases were identified. After adjusting for potential confounders, the highest quartile of total physical activity was statistically significantly associated with 13% decreased risk of cataract compared with the lowest (hazard ratio [HR], 0.87; 95% confidence interval [CI], 0.82-0.92). Walking or bicycling (>60 minutes/day vs. hardly ever; HR, 0.88; 95% CI, 0.82-0.95) and work or occupational activity (heavy manual labor vs. mostly sitting; HR, 0.84; 95% CI, 0.78-0.91) also were associated with decreased risk of cataract. Exercise training and home or housework were not associated with cataract risk. Leisure time inactivity was associated with increased risk of cataract (>6 vs. <1 hours/day; HR, 1.27; 95% CI, 1.07-1.50). The HR for high long-term total physical activity compared with low levels both at 30 years of age and at baseline was 0.76 (95% CI, 0.69-0.85). CONCLUSIONS Our findings indicate that high total physical activity, especially in the long term, and such specific types of physical activity as walking or bicycling and work or occupational activity, may be associated with decreased risk of age-related cataract. Conversely, high inactivity levels may be associated with increased risk of cataract.

[PMID: 24450445 PMCID: PMC4317801 DOI: 10.1111/cas.12360] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2013] [Revised: 01/17/2014] [Accepted: 01/18/2014] [Indexed: 01/16/2023] Open
Abstract
Early-onset cataracts are associated with insufficient antioxidative activity, and, therefore, a potential risk of cancer. This study investigated the risk of cancer after being diagnosed with early-onset cataracts. Retrospective claims data from the Taiwan National Health Insurance Research Database were analyzed. Study subjects were comprised of patients with early-onset cataracts, aged 20–55 years (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] code 366.00, 366.01, 366.02, 366.03, 366.04, 366.09, 366.17 and 366.18) and newly diagnosed between 1997 and 2010 (n = 1281), and a comparison cohort without the disease (n = 5124). Both cohorts were followed up until 2010 to estimate the incidences of cancer. We used the Poisson regression model to compare incidence rate ratios and the 95% confidence interval (CI). Cox proportional hazards regression was used to assess the hazard ratio (HR) of cancer associated with early-onset cataracts. The overall incidence rate of all cancers was 2.19-fold higher in the early-onset cataract cohort than in the comparison cohort (8.06 vs 3.68 per 1000 person-years) with an adjusted HR of 2.13 (95% CI = 1.48, 3.07). The site-specific analysis also showed a strong relationship, with adjusted HR of 3.24 ((95% CI = 1.30, 8.10) for head and neck cancer, 3.29 (95% CI 1.16, 9.31) for hepatoma and 3.19 (95% CI 1.34, 7.58) for breast cancer. The present study suggests that patients with early-onset cataracts are at an increased risk of being diagnosed with cancer in subsequent years.

Abstract
Background Age-related cataract (ARC) is the leading cause of blindness in the world. The relationship between body mass index (BMI) and risk of ARC is controversial across observational studies. We therefore performed this meta-analysis to evaluate the association between BMI and risk of ARC. Methods Eligible studies were identified through an electronic search of PubMed, Embase and the Cochrane Library. We pooled study-specific relative risks (RRs) and 95% confidence intervals (CIs) to determine the risk of ARC associated with BMI categories and per 1 kg/m2 increase in BMI. Results A total of 17 prospective cohort studies were included in the meta-analysis. The pooled RRs of ARC were 1.08 (95% CI, 1.01–1.16) for overweight and 1.19 (95% CI, 1.10–1.28) for obesity compared with normal weight. These findings were robust when stratified by sex, sample source, outcome types and confounders, while significantly differed by assessment of BMI and ARC, and duration of follow-up. The summary RR suggested that per 1 kg/m2 increase in BMI was associated with a 2% increased risk of ARC (RR 1.02, 95% CI 1.01–1.03). Pooled estimates of RRs consistently indicated a trend for subjects with a high BMI to develop posterior subcapsular cataracts (RR 1.19, 95% CI 1.06–1.35, for overweight; RR 1.50, 95% CI 1.24–1.81, for obesity; RR 1.04, 95% CI 1.01–1.06, per 1 kg/m2 increase in BMI) other than nuclear or cortical cataracts. Conclusions The overall findings suggest that elevated BMI may increase the risk of ARC, especially posterior subcapsular cataracts. Further trials are needed to investigate the effect of weight reduction in obese populations on the risk of ARC.

Abstract
Background To assess the socio-demographic and health-related risk factors associated with cataract subtypes in Korea. Methods A total of 11,591 participants (aged ≥40 years) were selected from the Korean National Health and Nutrition Examination Survey between 2008 and 2010. The Korean Ophthalmologic Society conducted detailed ophthalmologic examinations on these participants based on the Lens Opacity Classification System III. Risk factors for developing any type of cataract, and its subtypes (nuclear, cortical, posterior subcapsular and mixed), were identified from univariate and multivariate logistic regression analysis. Results The prevalence of cataracts was 40.1% (95% CI, 37.8 − 42.3%) in participants over 40 years old. Older age, lower monthly household income, lower education, hypercholesterolemia, hypertension, and diabetes mellitus (DM) were independent risk factors for development of any cataract. Older age, lower monthly household income, lower education, hypercholesterolemia, and DM were independent risk factors for development of pure cortical cataracts. Older age, lower education, metabolic syndrome, and DM were independent risk factors for development of pure nuclear cataracts. Older age and DM were independent risk factors for development of pure posterior subcapsular cataracts. Older age, lower monthly household income, lower education, and DM were independent risk factors for development of mixed cataracts. Conclusion Although socioeconomic disparities are related to cataract development, this study identified several “modifiable” risk factors that may help to lower the incidence of cataracts and associated vision loss. Improved control of blood pressure, blood, glucose, and cholesterol may help to reduce the incidence of cataracts in the general Korean population.

Abstract
Purpose To explore the relationship of the metabolic syndrome (MetS) and its components with age-related cataract in a representative Korean population. Methods We analyzed the data from the Korea National Health and Nutrition Examination Surveys (2008–2010). A total of 11,076 adults (4,811 men and 6,265 women) aged 40 and over who completed ophthalmologic examination were evaluated. Cataract was defined as the presence of cortical, nuclear, anterior (sub)capsular or posterior subcapsular cataract, from slit-lamp examination or previous cataract surgery. MetS was defined according to the Joint Interim Statement proposed in 2009 from the International Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute. Results The prevalence of cataract and MetS in this population was 39.4% (37.1% for men and 41.6% for women) and 38.5% (37.6% for men and 39.4% for women), respectively. Cataract prevalence tended to increase with the number of MetS components in both genders (both P< 0.001). After being controlled for confounders, however, MetS was significantly associated with cataract only in women (adjusted odds ratio (aOR), 1.24; 95% confidence interval (CI), 1.02–1.50]. Reduced HDL cholesterol, elevated fasting glucose, and elevated triglycerides were also significantly associated with cataract in women (aOR, 95% CI; 1.27 (1.07–1.50), 1.23 (1.01–1.50), and 1.26 (1.04–1.52), respectively). In the subgroup analysis for cataract subtype, MetS and reduced HDL cholesterol were significantly associated with nuclear cataract in women (aOR, 95% CI; 1.25 (1.07–1.55) and 1.25 (1.03–1.52), respectively). However, such associations were not found in men. Conclusions Our results suggest that MetS and its components appear to be associated with age-related cataract only among Korean women, especially in nuclear cataract.

Abstract
BACKGROUND Calcium is considered an important factor in the development of both osteoporosis and cataract. This study evaluated the association between osteoporosis and cataracts. OBJECTIVE To evaluate the prevalence of osteoporosis among patients undergoing cataract surgery, and the association between the two. PATIENTS AND METHODS This was a retrospective observational case-control study, conducted in the Central District of Clalit Health Services (a district of the largest health maintenance organization in Israel). All Clalit members in the district older than 50 years who underwent cataract surgery from 2000 to 2007 (n=12,984) and 25,968 age- and sex-matched controls comprised the sample. Electronic medical records of all patients in the study were reviewed. The main outcome measure was the prevalence of osteoporosis and the odds ratio of having osteoporosis among cataract patients compared with controls. RESULTS Demographically, 41.8% were men with a mean age of 68.7 ± 8.2 years. A logistic regression model for osteoporosis showed that age, female sex, higher socioeconomic class, smoking, chronic renal failure, hyperthyroidism, rheumatoid arthritis, inflammatory bowel diseases, and cataract are all associated with increased prevalence of osteoporosis. Obesity is a protective factor for osteoporosis. In all age-groups, osteoporosis was more prevalent in cataract patients than in the control group. CONCLUSION Among other well-known risk factors, osteoporosis is associated with the presence of cataracts. Common pathophysiological associations with both conditions, such as calcium imbalance, hormonal abnormalities, and shared genetic predisposition, are discussed.

Abstract
Metabolic syndrome is a cluster of diseases including central obesity, dyslipidemia, hyperglycemia, and high blood pressure. People with metabolic syndrome have been shown to be at an increased risk of developing cardiovascular disease, beyond the risk associated with individual components of the syndrome. The association of diabetes and hypertension with retinopathy, cataract, and raised intraocular pressure is well known. This review highlights the association of metabolic syndrome, including all its components, with various ocular conditions such as retinopathy, central retinal artery occlusion, cataracts, and raised intraocular pressure.

Abstract
PURPOSE To investigate whether the statin class of drugs reduces the risk of cataract extraction. DESIGN Case-control study. METHOD setting: Kaiser Permanente Southern California, which provides prepaid healthcare for 3.2 million residents by 6000 physicians. patient population: Eligible patients were those who had 5+ years of continuous enrollment in 2009. Cases were 13 982 patients who underwent cataract surgery in their first eye in 2009. Controls were the 34 049 patients who had an eye examination, but did not undergo cataract surgery or have a diagnosis of cataract in their medical record. observation procedure: The primary source of data to assess cataract surgery, treatment with statins, and other risk factors is the electronic database of Kaiser Permanente. main outcome measure: Use of the statin class of drug. RESULTS Patients who had cataract surgery were older, were more likely to be white, and appeared to have more coronary artery disease but less diabetes. The proportion of statin users appeared to be greater among those with cataract surgery (64.3%) compared to those without a diagnosis of cataract or cataract surgery (55.5%). After adjustment for age, sex, race, smoking status, diabetes, and coronary artery disease, longer-term statin use was found to be protective against cataract extraction (OR: 0.93, P = .02), while shorter-term use was associated with cataract surgery (OR: 1.11, P < .0001). Age-stratified logistic regression analysis showed that statin use of 5 years or more was protective against cataract surgery in the younger age group (50-64 years), while shorter-term use (<5 years) was associated with an increased risk of surgery in both the younger and older age groups (60+ years). CONCLUSION The current study finds that recent longer-tem statin use was protective against cataract surgery in younger patients (50-64 years of age), while shorter-term use was associated with an increased risk of surgery. One strength of the current study is information on the large number of incident cases of cataract extraction and the electronic database on drug use. Additional studies will be needed to understand the difference in effect between longer- and shorter-term users of statins.

Abstract
Vitamin deficiencies are prevalent in celiac disease (CD) and are associated with cataract formation, but it is unknown whether persons with CD are at increased risk of cataract. The authors' objective in this population-based cohort study was to determine the risk of cataract among persons with biopsy-verified CD. Data on CD were collected from reports on small intestinal biopsies performed between July 1969 and February 2008 in the 28 regional pathology departments in Sweden. The authors identified 28,756 persons with CD (villous atrophy, Marsh pathology stage 3). For each person with CD, Statistics Sweden selected up to 5 controls matched for age and sex from the Total Population Register. Data on cataract were obtained from the Swedish National Hospital Discharge Register and the National Day-Surgery Register. Cox regression analysis was used to estimate the risk of cataract. During a median follow-up period of 9 years, the authors identified 1,159 cataracts among persons with CD (909 were expected) (hazard ratio = 1.28, 95% confidence interval: 1.19, 1.36). The absolute risk of cataract was 397/100,000 person-years in CD, with an excess risk of 86/100,000 person-years. In conclusion, this study found an increased risk of developing cataract in patients with CD.
