Methods: In this cross-sectional study, 106 of 272 cataract surgical centers in Iran were selected through multistage random cluster sampling from all provinces. In each province, the selected number of centers was proportionate to the number of cataract surgeries, and in each center, the selected number of charts was proportionate to the center’s number of cataract surgeries, from which we retrieved intraoperative complications.
Results: The prevalence of intraoperative complications of cataract surgery was 5.04% (95% confidence interval, CI, 3.53–6.54%) in 2006, which decreased significantly to 3.44% (95% CI 1.84–5.04%) in 2010. The most common complication was posterior capsular rupture/vitreous loss which decreased from 4.29% (95% CI 2.93–5.66%) in 2006 to 2.81% (95% CI 1.3–4.31%) in 2010. The next most common complication was suprachoroidal hemorrhage at 0.56% (95% CI 0.25–0.87%) in 2006 and 0.46% (95% CI 0.3–0.62%) in 2010. The least common complication concerned intraocular lens (IOL)-drop. Complications were seen most with lensectomy, while phacoemulsification caused the least complications. Mean hospitalization time in uncomplicated cases was 0.59 days (95% CI 0.58–0.61 days) and in complicated cases 1.14 days (95% CI 1.07–1.20 days; p < 0.001).
Conclusion: Complications of cataract surgery in Iran had a decreasing trend during 2006–2010. However, results from 2010 indicate that cataract surgical complications still need to be focused on. Hospitalization was longer for cases with complications, and further reducing this could help decrease costs of cataract surgery. 相似文献
Methods: Using the resources of the Rochester Epidemiology Project, a retrospective population-based, case-control study was performed. Cases included 6024 county residents aged 50 years and older who had first-eye cataract surgery between 1 January 2004 and 31 December 2011. Controls included residents who had never had cataract surgery and were matched to cases by age, sex, and index date within 1 month of surgery. Statin medications continuously prescribed for at least 1 year before the surgery date (cases) or index date (controls) were examined. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression models.
Results: There were 2557 (42%) statin users among cases having cataract surgery compared to 2038 (34%) statin users among controls never having had cataract surgery (p < 0.0001). Incident cataract surgery was significantly associated with increased odds of statin use (OR 1.29, 95% CI 1.19–1.55) after adjusting for age, sex, diabetes, cardiovascular disease, cerebrovascular disease, peripheral vascular disease, renal disease, oral and inhaled steroid use, and selective serotonin reuptake inhibitor use. The association was consistent in both subgroups of women (OR 1.34, 95%CI 1.22–1.49) and men (OR 1.17, 95% CI 1.05–1.30).
Conclusions: Incident cataract surgery was associated with increased odds of statin use, and underscores the possibility that increasing statin use could be contributing to rising rates of cataract surgery. 相似文献
Methods: A cross-sectional population-based survey was performed on a representative sample of urban and rural individuals aged ≥50 years of the province. Blindness was defined as presenting visual acuity (PVA) <3/60 in the better eye. Moderate visual impairment (MVI) and severe visual impairment (SVI) were defined as 6/60 ≤ PVA <6/18 and 3/60 ≤ PVA <6/60 in the better eye, respectively. Diabetes mellitus (DM) was determined based on random blood sugar (RBS) levels ≥200 mg/dL or a previous diagnosis. We used the Scottish grading system to grade DR.
Results: We invited 2975 individuals from 85 clusters. Age- and sex-adjusted prevalence and 95% confidence interval (CI) of blindness, SVI, MVI, and DM in 2587 participants (response rate: 86.9%) were 1.5% (95% CI: 1.1–2.0), 1.5% (95% CI: 0.9–2.0), 11.3% (95% CI: 9.9–12.7) and 21.4% (95% CI: 19.2–23.7), respectively. The leading causes of blindness were cataract (47.1%), age-related macular degeneration (14.7%) and DR (8.8%). Cataract surgery (CS) coverage was 69.3%. The main challenges for CS were cost and unawareness. The outcome of CS was good in 66.9% of operated eyes. Any DR and/or maculopathy were observed in 25.3% (95% CI: 21.0–29.5) of subjects including 12.6% (95% CI: 9.7–15.6) sight-threatening DR. In previously known DM cases, 215 (41.7%) had never undergone an eye examination for DR.
Conclusion: The proportion of avoidable blindness and DR is considerable in Gilan Province. 相似文献
Methods: A prospective study was carried out that included 102 eyes from 51 patients undergoing intraocular surgery between December 2016 and April 2017. In each patient, the surgical eye (control group) only received ocular irrigation and the opposite eye (study group) received ocular irrigation with eyelid margin cleaning. Normal saline solution was used in all procedures. In each group, samples from the lower eyelid margins and lower fornices were cultured before and after cleaning. Povidone iodine and antibiotic eye drops were instilled after specimen collection.
Results: The most common bacterial isolate of all groups was Staphylococcus spp. There were no statistically significant differences of positive cultures between the control and study groups in either lower eyelid margins (Odds ratio [OR], 2.19; 95% CI, 0.84–5.72) nor lower fornices (OR, 0.93; 95% CI, 0.43–2.00). In addition, there were no statistically significant differences of positive cultures between before and after eyelid cleanings from both lower eyelid margins (OR, 2.74; 95% CI, 0.53–14.24) and lower fornices (OR, 0.73; 95% CI, 0.21–2.57).
Conclusions: Eyelid margin cleaning with normal saline solution immediately before intraocular surgery did not help to decrease microbial loading on the ocular surfaces. The rate of bacterial contamination, however, was not increased which could be due to not performing eyelid compression. 相似文献
Methods: A population-based prevalence survey was conducted in each Kano LGA. We used a two-stage systematic and quasi-random sampling strategy to select 25 households from each of 25 clusters in each LGA. All consenting household residents aged 1 year and above were examined for trachomatous inflammation–follicular (TF), trachomatous inflammation–intense (TI) and trichiasis.
Results: State-wide crude prevalence of TF in persons aged 1–9 years was 3.4% (95% CI 3.3–3.5%), and of trichiasis in those aged ≥15 years was 2.3% (95% CI 2.1–2.4%). LGA-level age- and sex-adjusted trichiasis prevalence in those aged ≥15 years ranged from 0.1% to 2.9%. All but 4 (9%) of 44 LGAs had trichiasis prevalences in adults above the elimination threshold of 0.2%. State-wide prevalence of trichiasis in adult women was significantly higher than in adult men (2.6% vs 1.8%; OR = 1.5, 95% CI 1.3–1.7; p = 0.001). Four of 44 LGAs had TF prevalences in 1–9-year-olds between 10 and 15%, while another six LGAs had TF prevalences between 5 and 9.9%. In 37 LGAs, >80% of households had access to water within 30 minutes round-trip, but household latrine access was >80% in only 19 LGAs.
Conclusion: Trichiasis is a public health problem in most LGAs in Kano. Surgeons need to be trained and deployed to provide community-based trichiasis surgery, with emphasis on delivery of such services to women. Antibiotics, facial cleanliness and environmental improvement are needed in 10 LGAs. 相似文献
Methods: We used cross-sectional data from the 2006–2010 Behavioral Risk Factor Surveillance System to examine six measures of HRQoL: self-reported health, physically unhealthy days, mentally unhealthy days, activity limitation days, life satisfaction, and disability. Visual impairment was categorized as no, a little, or moderate/severe. We examined the association between visual impairment and HRQoL using logistic regression accounting for the survey’s complex design.
Results: Overall, 23.0% of the participants reported a little difficult seeing, while 16.8% reported moderate/severe difficulty seeing. People aged 40–64 years with moderate/severe visual impairment had more frequent (≥14) physically unhealthy days, mentally unhealthy days, and activity limitation days in the last 30 days, as well as greater life dissatisfaction, greater disability, and poorer health compared to people reporting no or a little visual impairment. After controlling for covariates (age, sex, marital status, race/ethnicity, education, income, state, year, health insurance, heart disease, stroke, heart attack, body mass index, leisure-time activity, smoking, and medical care costs), and compared to people with no visual impairment, those with moderate/severe visual impairment were more likely to have fair/poor health (odds ratio, OR, 2.01, 95% confidence interval, CI, 1.82–2.23), life dissatisfaction (OR 2.06, 95% CI 1.80–2.35), disability (OR 1.95, 95% CI 1.80–2.13), and frequent physically unhealthy days (OR 1.69, 95% CI 1.52–1.88), mentally unhealthy days (OR 1.84, 95% CI 1.66–2.05), and activity limitation days (OR 1.94, 95% CI 1.71–2.20; all p < 0.0001).
Conclusion: Poor HRQoL was strongly associated with moderate/severe visual impairment among people aged 40–64 years. 相似文献
Method: Rapid assessment of refractive error (RARE) study following the RARE protocol was conducted in a northern district (i.e., Sirajganj) of Bangladesh (January 2010–December 2012). People aged 15–49 years were selected, and eligible participants had habitual distance and near visual acuity (VA) measured and ocular examinations were performed in those with VA<6/18. Those with phakic eyes with VA <6/18, but improving to ≥6/18 with pinhole or optical correction, were considered as RE and people aged ≥35 years with binocular unaided near vision of <N8 were considered presbyopic.
Result : A total of 3,043 people were examined, of which 143 had RE (4.7%, 95% CI: 3.9–5.5). Among people aged ≥35 years (n = 1402), 869 had presbyopia (62.0, 95% CI: 59.4–64.5). Spectacle coverage for RE and presbyopia were 13.3% (95% CI 7.7–18.9) and 3.2% (95% CI 2.2–4.6), respectively. “Unaware of the problem” was the main reason for not utilizing any optical services among the people with RE (92.8%) and presbyopia (89.5%). Extrapolating the survey findings to the 2011 national census data, the magnitude of RE among people aged 15–49 years in Bangladesh is estimated to be 3,493,980 people (95% CI 2,899,260–4,088,700), of whom 3,029,280 people do not use any spectacles.
Conclusion : The burden of RE and presbyopia is substantial in Bangladesh. Improving awareness and availability of refraction services is required to correct REs and presbyopia in Bangladesh. 相似文献
Methods: Through a cross-sectional study using randomized cluster sampling, 60 clusters were selected in Sari, a city in the North of Iran. In each cluster, 20 people over 54 years of age were chosen systematically and were invited to participate in the study. After enrollment, all participants had optometric and ophthalmologic exams including slit lamp biomicroscopy and fundoscopy.
Results: Of the 1185 selected persons, 937 (79.1%) participated in this study (age range 55–87 years). The prevalence of cataracts, AMD, glaucoma, and DR in at least one eye was 29.6% (95% confidence interval [CI] 26.6–32.5), 5.8% (95% CI: 4.3–7.3), 3.7% (95% CI: 2.5–5.0), and 2.7% (95% CI: 1.6–3.7), respectively. All prevalences significantly increased with aging. AMD was more prevalent in men (7.4%) than women (4.4%) (p = 0.054). Overall, 35.8% (95% CI: 32.7–38.8) of participants had at least one of the four conditions; this rate was 27.4% for the 55–59-year old age group and 52.4% for those over 75 years of age.
Conclusion: Overall, 35.8% of the studied population had at least one of the four diseases. Cataracts, followed by AMD, are the most common age-related eye diseases in the Iranian population, and thus, precise planning along with enhanced diagnostic and therapeutic facilities are necessary. 相似文献
Methods: Pre- and post-intervention study measuring visual function improvement following cataract surgery. Presenting visual acuity (VA) was measured and visual function documented using the Indian vision function questionnaire (IND-VFQ).
Results: All 174 persons undergoing cataract surgery from November 2009 to January 2011 in Timor-Leste were included. Mean age was 65.4 years; 113 (64.9%) were male, 143 (82.1%) were from a rural background and 151 (86.8%) were illiterate. Pre-operatively, 77 of 174 patients (44.3%, 95% confidence interval, CI, 37.0–51.7%) were blind (VA ≤3/60), 77 (44.3%, 95% CI 37.0–51.7%) were visually impaired (VA <6/18–>3/60), while 20 (11.5%, 95% CI 7.4–16.9%) had presenting acuity ≥6/18 in the better eye. Following surgery, significant improvement in visual function was demonstrated by an effect size of 2.8, 3.7 and 3.9 in the domains of general functioning, psychosocial impact and visual symptoms, respectively. Four weeks following surgery, 85 patients (48.9%, 95% CI 41.5–66.3%) had a presenting VA ≥6/18, 74 (42.5%, 95% CI 35.3–45.9%) were visually impaired and 15 (8.6%, 95% CI 5.0–13.6%) were blind. IND-VFQ improvement occurred even in patients remaining visually impaired or blind following surgery.
Conclusion: In this setting, cataract surgery led to a significant improvement in visual function but the VA results did not meet World Health Organization quality criteria. IND-VFQ results, although complementary to clinical VA outcomes did not, in isolation, reflect the need to improve program quality. 相似文献
Methods: A cross-sectional interviewer-administered survey together with eye screenings was conducted among schoolchildren in the capital Yerevan and in Gegharkunik Province. The study used multi-stage random sampling to obtain the sample of 1260 schoolchildren. Study questionnaires were developed based on the Sydney Myopia Study questionnaire. Continuous reading was defined as the average number of hours spent reading or on near work without a break. Children underwent measurements of visual acuity using a Golovin-Sivtsev eye chart, cycloplegic retinoscopy, and dilated fundus examination.
Results: The mean age of the children was 13 years, and myopia was present in 18.1%. The prevalence of myopia was higher among Yerevan children (23.3%) than those living in Gegharkunik Province (12.5%). In the adjusted model, myopia was significantly associated with age (odds ratio, OR, 1.11, 95% confidence interval, CI, 1.04–1.18), region (OR 2.40, 95% CI 1.62–3.57), school achievement (OR 1.62, 95% CI 1.05–2.51), parental myopia (OR 2.89, 95% CI 1.79–4.69), and continuous reading (OR 1.99, 95% CI 1.31–3.02), but not near work (OR 0.97, 95% CI 0.89–1.05).
Conclusion: The study found that a positive family history of myopia and environmental factors had independent associations with myopia. The number of near work hours did not play a major role in the development of myopia, but length of time of focused continuous reading did. 相似文献
Methods: We used cross-sectional data from the 2006–2010 Behavioral Risk Factor Surveillance System to examine six HRQoL measures: self-reported health, physically unhealthy days, mentally unhealthy days, activity limitation days, life satisfaction, and disability. Visual impairment was categorized as no, a little, and moderate/severe. We examined the association between self-reported visual impairment and HRQoL using logistic regression accounting for the survey’s complex design.
Results: People with self-reported moderate/severe visual impairment had more frequent (≥14) physically unhealthy days, mentally unhealthy days, and activity limitation days in the last 30 days compared to those reporting a little or no visual impairment. After controlling for all covariates (age, sex, marital status, race/ethnicity, education, income, diabetes, heart disease, stroke, heart attack, body mass index, leisure time activity, smoking, and medical care cost concerns) and comparing to those with no self-reported visual impairment, people reporting a little visual impairment were more likely to have fair/poor health (odds ratio, OR, 1.2, 95% confidence interval, CI, 1.1–1.3), life dissatisfaction (OR 1.6, 95% CI 1.3–2.0), and disability (OR 1.5, 95% CI 1.3–1.6), and those with self-reported moderate/severe visual impairment had more fair/poor health (OR 1.8, 95% CI 1.6–2.0), life dissatisfaction (OR 2.3, 95% CI 1.8–2.9), and disability (OR 2.0, 95% CI 1.8–2.2). They also had more frequent physically unhealthy days (OR 1.9, 95% CI 1.7–2.1), mentally unhealthy days (OR 1.8, 95% CI 1.5–2.1), and activity limitations days (OR 1.9, 95% CI 1.6–2.2).
Conclusion: Poor HRQoL is strongly associated with the severity of self-reported visual impairment among people aged ≥65 years. 相似文献
Methods: This was a cross-sectional population-based study using multi-stage cluster sampling from rural-dwellers of villages in the north and southwest of Iran. All participants underwent vision testing including measurement of visual acuity and refraction followed by slit lamp examination by an ophthalmologist through which the presence of corneal opacity was determined.
Results: The participants were 3314 people (response rate = 86.5%), and 56.3% were female. The prevalence of corneal opacity in at least one eye in the studied subjects was 1.68% (95% CI: 1.08–2.27%); 1.07% (95% CI: 0.04–3.43%) and 2.47% (95% CI: 1.49–3.43%) in women and men, respectively, and 1.45% (95% CI: 0.4–2.45%) and 1.97% (95% CI: 1.3–2.94%) in the southwest and north of the country, respectively. The prevalence of corneal opacity was related to male gender (OR = 2.06, 95% CI: 1.13–3.74) and age (OR = 1.06, 95% CI: 1.04- 1.09) but not with education level. The prevalence of visual impairment and blindness among cases with corneal opacity was 46.2% and 19.2%, respectively.
Conclusion: Given the high prevalence of corneal opacity in rural areas in Iran, it is essential to prioritize rural areas for allocation of resources and facilities for the diagnosis, screening, and necessary treatment measures. 相似文献
Methods: A retrospective review of medical records of 71 Jordanian patients (45 males and 26 females) diagnosed with retinoblastoma (114 eyes) between June 2003 and May 2013 was conducted. Patient sociodemographic and relevant characteristics were collected from records. Patients with bilateral retinoblastoma were treated with chemoreduction and focal consolidation. Lens-sparing radiation therapy and enucleation were reserved for eyes that failed chemoreduction combined with focal therapy. In cases of unilateral retinoblastoma, primary enucleation was recommended for eyes with advanced unilateral disease (Reese-Ellsworth classification groups IV and V). Kaplan-Meier survival and Cox regression multilevel analysis were used to analyze the data.
Results: Median age at diagnosis was 12 months. The follow-up period ranged from 0.25–160 months (mean 26.9 months). The Kaplan–Meier estimate of globe survival of the 114 eyes was 68.0% at 1 year, 63.3% at 2 years, and 62.1% at 5 years. The mean survival time was 101.6 months (95% confidence interval, CI, 87.6–115.6 months). In multivariable-adjusted analysis, advanced stage of the disease (hazard ratio, HR, 5.1, 95% CI 2.3–11.6), unilateral disease (HR 3.3, 95% CI 1.4–8.1), and delay in diagnosis (HR 2.4, 95% CI 1.1–5.5) were significantly associated with increased hazard of enucleation.
Conclusion: The overall ocular survival rate for eyes with retinoblastoma was close to regional and international figures. Disease stage, laterality, and delay in diagnosis were significant predictors of enucleation. 相似文献
Methods: Children suspected of having low vision were identified by KIs or Aravind Eye Hospital personnel in Coimbatore District. All identified children underwent a cycloplegic refraction and full eye exam. A primary cause of decreased vision was determined for each child. The prevalence of FLV was calculated for children 6–14 years old. Spectacles and low vision devices were provided free of charge.
Results: 345 children aged 6–14 years were referred and 231 had FLV. The positive-predictive value of KI referrals was 64.5%. The prevalence of FLV was 0.071% (7.1 per 10,000; 95% CI 0.062–0.080%) and ranged from 0.026% to 0.141% across the district’s blocks. Older children (age 11–14 years; OR 1.41; 95% CI 1.09–1.82) and males (OR 1.52; 95% CI 1.16–1.98) had greater odds of being diagnosed with FLV. The most common causes of FLV were retinal disorders (30.0%) and amblyopia (25.5%). Low vision devices were provided to 169 children who had a mean near and distance visual acuity improvement of 0.31 and 0.63 logMAR, respectively (p < 0.001).
Conclusions: This study reports a moderate prevalence of FLV and demonstrates the ability of KIs to identify school-age children with FLV in South India. The provision of basic low vision services can improve visual outcomes in this population. 相似文献
Methods: A total of 51 clusters of 80 people (all ages) were sampled with probability proportionate to size and compact segment sampling. Visual acuity (VA) was measured with a tumbling “E” chart. An ophthalmic nurse examined people with VA<6/18 in either eye. The presence of hearing and physical impairments were assessed using clinical examination, and self-reported visual problems using the Washington Group Short Set.
Results: In total, 4080 people were enumerated of whom 3567 were screened (response rate 87%). The overall prevalence of visual impairment was 2.3% (95% CI 1.8–3.0%) and blindness was 0.6% (0.3–1.0%). The prevalence of both blindness and visual impairment increased rapidly with age, so that the vast majority of cases of visual impairment (84%) and blindness (82%) were in people aged 50+. Posterior segment disease and cataract were the main causes of blindness and visual impairment, with refractive error also an important cause of visual impairment. Cataract surgical coverage (proportion of all cataracts that had received surgery) was relatively high (87% of people at VA<6/60). Post-surgery outcomes were poor, with 31% of operated eyes having VA<6/60. Among the 82 people with visual impairment, 22% had a physical impairment or epilepsy and 30% had a hearing impairment. Self-reported difficulties in vision were relatively closely related to clinical measures of visual impairment.
Conclusions: Ophthalmic programmes in Cameroon need to incorporate control of posterior segment diseases while also working to improve outcomes after cataract surgery. 相似文献
Methods: A retrospective cohort study of consecutive patients who underwent their first pars-plana vitrectomy for PDR between April 2004 and May 2005 was performed. Survival status on 1 May 2012 was the primary endpoint. The Kaplan-Meier life table method was used to determine survival rates. Univariate and multiple variable Cox proportional hazards regressions were used to identify risk factors for mortality.
Results: A total of 148 patients were included in the study, with a mean age of 54 years (range 20–80 years) at time of surgery. The 3-, 5- and 7-year survival rates were 94%, 86% and 77%, respectively (95% confidence interval, CI, 88–97%, 79–91% and 68–84%, respectively). Renal failure was the most common cause of death. The presence of limb ulcers at baseline was the most important prognostic indicator for mortality, with a hazard ratio of 3.13 (95% CI 1.46–6.71, p = 0.003) and a survival rate at 5 years reduced to 79%.
Conclusion: The 5-year survival rate remains comparable to those reported 20 years ago despite a lowering in threshold for vitrectomy and increased health awareness. Limb ulcers are strongly associated with increasing mortality. Clinicians should remain mindful of the systemic associations of diabetes particularly in advanced retinal disease. 相似文献
Methods: In the first phase of the Shahroud Eye Cohort Study, 5190 people in 300 clusters from Shahroud city in the northeast of Iran participated in the study. The second phase of the study was conducted 5 years later in 2014. Vision testing, refraction, slit lamp examination, and fundus examination were performed for all participants. In this study, XFS was determined by an ophthalmologist using slit lamp biomicroscopy.
Results: Of the 5190 first phase study participants, 4737 participated in the second phase (response rate 91.3%). In this study, the prevalence of XFS was 0.46% (95% confidence interval, CI, 0.24–0.68%) and the prevalence of bilateral XFS was 0.20% (95% CI 0.07–0.33%). XFS prevalence in men was 0.74% (95% CI 0.28–1.20%) and in women 0.26% (95% CI 0.07–0.45%). In a multivariable-adjusted logistic regression model, age, sex, diabetes, smoking status, dyslipidemia, and hypertension were entered into the model as covariables, where older age (odds ratio, OR, 1.18, 95% CI 1.08–1.28) was the only variable that remained significantly associated with XFS prevalence.
Conclusion: The prevalence of XFS in this study was very low. Similar to other studies, age was a factor associated with this syndrome. 相似文献
Methods: A total of 1015 residents of Kashi participated in this 2013 cross-sectional study. To evaluate clinical characteristics, each subject completed (1) a dry-eye questionnaire detailing symptoms of dry eye, (2) Schirmer’s I-test (SIT), (3) tear-film break-up time (BUT) test, and fluorescein staining of the cornea. Dry eye was defined as the existence of dry eye symptoms and at least two positive clinical signs. Data were analyzed using SPSS software. The prevalence and risk factors of dry eye were evaluated using a multivariate model.
Results: Overall, 282 (27.8%) of the 1015 participants were diagnosed with dry eye (95% confidence interval (CI): range, 25.5–30.1). The prevalence of dry eye among Han persons (37.9 %) (95% CI: range, 35.8–40.0) was higher than that among Uyghurs (21.8%) (95% CI: 19.6–24.0) (p < 0.05). The prevalence of dry eye was 25.6% (95% CI: range, 23.3–27.8) among men and 28.7% (95% CI: 26.5–30.9) among women (p > 0.05). Risk factors for dry eye included ethnicity, age, occupation, arthritis, and dry mouth.
Conclusions: Our study revealed a higher prevalence of dry eye among Han than Uyghur persons in Kashi. Dry eye was significantly associated with environment and ethnicity. 相似文献
Methods: A protocol was registered at PROSPERO (CRD42015020622). A systematic search of Medline (Ovid), PubMed, and Embase (Ovid) was conducted on 6 June 2015. Reference lists from identified studies and four clinical trial registries were searched for additional studies. Participants were required to be over the age of 40 years, and AMD status must have been objectively assessed. The Risk Of Bias In Non-Randomized Studies – of Interventions (ROBINS-I) tool was used to assess the risk of bias. Random-effects meta-analyses were performed.
Results: A total of 12 reports from 10 studies were included in the meta-analysis. Late AMD was associated with elevated rates of all-cause (nine studies, hazard ratio (HR) 1.20, 95% confidence interval, CI, 1.02–1.41) and cardiovascular mortality (six studies, HR 1.46, 95% CI 1.13–1.98), but early AMD was not (all-cause mortality, 10 studies, HR 1.06, 95% CI 0.98–1.14; cardiovascular mortality, five studies, HR 1.12, 95% CI 0.96–1.31). There was no evidence of an association between early or late AMD and cancer mortality (early AMD, three studies, HR 1.17, 95% CI 0.78–1.75; late AMD, three studies, HR 1.01, 95% CI 0.77–1.33).
Conclusion: Late AMD is associated with increased rates of all-cause and cardiovascular mortality, suggesting shared pathways between late AMD and systemic disease. 相似文献
Methods: This case-control study comprised 165 subjects (57 patients with nAMD and 108 controls). Controls were matched to cases by age and sex. Participants completed a questionnaire that included questions about sleep duration and quality. Four categories of sleep duration were established; <6 hours, 6–7 hours, 7–8 hours and >8 hours. Association of sleep duration and nAMD was assessed by logistic regression analysis. Multiple logistic regression models were performed to control for possible confounders.
Results: We found a significant association between short sleep duration and nAMD (for <6 hours, odds ratio, OR, 3.29, 95% confidence interval, CI, 1.32–8.27; for 6–7 hours, OR 2.25, 95% CI 0.80–6.32; and for >8 hours, OR 1.39, 95% CI 0.53–3.73) compared with the reference category of 7–8 hours. This association remained significant after adjustment for confounders (<6 hours, OR 3.09, 95% CI 1.20–7.97). In addition, a borderline significant association was observed between self-reported very bad sleep quality and nAMD (OR 2.84, 95% CI 1.02–7.88). The highest rate of sleep medication use was found in the nAMD group (p < 0.001).
Conclusion: Our findings provide evidence to support an association between short sleep duration and nAMD. Considering strategies to improve sleep in these patients may prevent the negative effects of sleep deficiency. 相似文献
