    ABSTRACT: Purpose: To examine the frequency and causes of visual impairment (VI) in a select population of Danish adults. Methods: A total of 3843 adults aged 20-94 years from the Danish General Suburban Population Study (GESUS) were included in the population-based, cross-sectional ophthalmological study, Danish Rural Eye Study (DRES). All DRES participants received a comprehensive general health examination preceding their eye examination, including measurement of best-corrected visual acuity (BCVA) for each eye, bilateral 45° retinal fundus photographs and further ophthalmological examination where indicated. Results: Overall, 3826 of 3843 participants (99.6%) had bilateral visual acuity measurements. The overall frequency of VI (BCVA <20/40 in the better-seeing eye) was 0.4% (95% confidence interval, CI, 0.2-0.7%; n = 15) among all DRES participants, 0.6% (95% CI 0.3-1.0%; n = 15) among participants >50 years and 3.7% (95% CI 2.1-6.5%; n = 11) in participants >80 years. The primary causes of VI in the better-seeing eye were age-related macular degeneration (AMD) in 46.7% (7/15) and cataract in 26.7% (4/15). A total of 43.3% (n = 115) of participants >80 years were pseudophakic in one or both eyes. The frequency of diabetes (HbA1c ≥48 mmol/mol or self-reported diagnosis) was 5.9% (n = 227), including 1.3% (n = 51) newly diagnosed in the GESUS. Of participants determined to have VI due to exudative AMD, 50% had received anti-vascular endothelial growth factor (VEGF) treatment. Conclusion: We report a relatively low frequency of VI among Danish adults over 59 years of age compared with that observed 10-15 years ago, which is both consistent with other recent Scandinavian studies and reflective of our relatively healthy and mobile population sample.

    ABSTRACT: Purpose: To examine whether there is an association between neighborhood deprivation and age-related eye diseases, particularly macular degeneration, cataract, diabetes-related eye complications, and glaucoma. Methods: The study population comprised a nationwide sample of 2,060,887 men and 2,250,851 women aged 40 years or older living in Sweden who were followed from 1 January 2000 until the first hospitalization/outpatient registration for age-related eye disease during the study period, death, emigration, or the end of the study period on 31 December 2010. Multilevel logistic regression was used to estimate the association between neighborhood deprivation and age-related eye diseases. Results: In men, the odds ratio (OR) for age-related eye diseases for those living in high-deprivation neighborhoods compared to those living in low-deprivation neighborhoods remained significant after adjustment for potential confounding factors (macular degeneration, OR 1.08, 95% confidence interval [CI] 1.03-1.12; cataract, OR 1.31, 95% CI 1.26-1.35; diabetes-related eye complications, OR 1.36, 95% CI 1.30-1.43; glaucoma, OR 1.11, 95% CI 1.06-1.15). In women, similar patterns were observed (macular degeneration, OR 1.11, 95% CI 1.07-1.15; cataract, OR 1.36, 95% CI 1.31-1.40; diabetes-related eye complications, OR 1.50, 95% CI 1.42-1.59; glaucoma, OR 1.12, 95% CI 1.08-1.17). Conclusion: Our results suggest that neighborhood deprivation is associated with age-related eye diseases in both men and women. These results implicate that individual-as well as neighborhood-level factors are important for preventing age-related eye diseases.

    ABSTRACT: To investigate seasonality in onset and incidence of central retinal vein occlusion (CRVO) in Stockholm, Sweden. A retrospective consecutive population-based case series of patients presenting to the emergency department with CRVO from January 2008 through December 2013 at the St Erik Eye Hospital. Date, age at occurrence and sex were recorded in the study cohort. A total of 854 patients presented with CRVO during the study period. Peak CRVO onset occurred during the winter/spring period and was significantly higher than during the summer/autumn period. The number of patients presenting by season were: 166 (28.8%, 95% confidence interval, CI, 25.3-32.6%) in winter, 172 (29.9%, 95% CI 26.3-33.7%) in spring, 131 (22.7%, 95% CI 19.5-26.3%) in summer, and 107 (18.9%, 95% CI 15.6-22.0%) in autumn (p < 0.0002). There were more males, accounting for 53.9% of subjects (460/856; p = 0.029). Mean annual incidence of CRVO was 2/10,000 for persons aged over 40 years, increasing from 0.25/10,000 at 45 years to 7/10,000 at 85 years (p < 0.001). The onset of CRVO in Stockholm, Sweden, had a significant seasonal pattern and most cases occurred during the winter-spring period. The highest incidence of CRVO was found in elderly people.

    ABSTRACT: To determine the prevalence and associated factors of pinguecula in a rural Chinese population aged ≥50 years in Eastern China. This cross-sectional, population-based survey included an age-stratified random sample of 1108 residents living in Lvxiang Town of Jinshan District. Participants were requested to complete a comprehensive questionnaire to collect demographic data, history of systemic diseases and lifestyle details. The presence of pinguecula on slit lamp examination was recorded. The prevalence of pinguecula and its associated factors were investigated by logistic regression models. Among 1108 eligible subjects, 959 participated in the study, with an average age of 65.1 ± 9.2 years (range 50-89 years). The overall age-adjusted prevalence of pinguecula in this population was 75.57% (95% confidence interval 71.79-79.35%). Logistic regression analysis revealed that age (p = 0.002) and working outdoors (daily sunlight exposure ≥2 hours; p = 0.001) were independent risk factors for pinguecula. In addition, sex, education level, alcohol intake, smoking and decreased tear break-up time did not have associations with the development of pinguecula after adjusting for age and outdoor work occupations. The prevalence of pinguecula was 75.57% in this Chinese population aged ≥ 50 years from a coastal rural area of Shanghai, Eastern China, which was higher than the majority of previous findings. Age and working outdoors were independent risk factors for pinguecula.

    ABSTRACT: To determine factors associated with angle-closure disease, particularly in those with structural or functional damage to the eyes, in an elderly Chinese population. A total of 460 individuals aged over 72 years were recruited. The association of angle-closure diseases, including primary angle-closure suspect (PACS), primary angle-closure (PAC) and primary angle-closure glaucoma (PACG), with various systemic and ocular characteristics was evaluated using multivariate logistic regression analyses. Of 374 phakic subjects, 199 (53.2%) had angle-closure disease, including 135 PACS, 46 PAC, and 18 PACG. The majority of those with untreated PACG (10/13, 76.9%) had presenting intraocular pressure (IOP) < 20 mmHg. Independent risk factors for angle-closure disease were lower Van Herick grading, shallower central anterior chamber depth (ACD), and higher post-mydriatic IOP (all p < 0.05). Central and peripheral ACD estimation correlated weakly, only 60.8% of angle-closure eyes had generalized narrowing of ACD as a Van Herick grading ≤2 and central ACD ≤ 2.83 mm. A criterion considering either central or peripheral ACD identified 91% of angle-closure eyes, including all PACG. A higher post-mydriatic IOP was associated with a diagnosis of PAC or PACG among angle-closure eyes (p = 0.002). Both central and peripheral ACD should be evaluated and shallowing of either one should be an indication for gonioscopic examination to maximize detection of angle-closure disease in elderly Chinese persons. PAC and PACG were associated with higher post-mydriatic IOP than PACS, although subjects with PACG frequently presented with normal IOP.

    ABSTRACT: To report on the accuracy of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for identifying patients with polymyalgia rheumatica (PMR) and concurrent noninfectious inflammatory ocular conditions in a large healthcare organization database. Queries for patients with PMR and uveitis or scleritis were executed in two general teaching hospitals' databases. Patients with ocular infections or other rheumatologic conditions were excluded. Patients with PMR and ocular inflammation were identified, and medical records were reviewed to confirm accuracy. The query identified 10,697 patients with the ICD-9-CM code for PMR and 4154 patients with the codes for noninfectious inflammatory ocular conditions. The number of patients with both PMR and noninfectious uveitis or scleritis by ICD-9-CM codes was 66. On detailed review of the charts of these 66 patients, 31 (47%) had a clinical diagnosis of PMR, 43 (65%) had noninfectious uveitis or scleritis, and only 20 (30%) had PMR with concurrent noninfectious uveitis or scleritis confirmed based on clinical notes. While the use of ICD-9-CM codes has been validated for medical research of common diseases, our results suggest that ICD-9-CM codes may be of limited value for epidemiological investigations of diseases which can be more difficult to diagnose. The ICD-9-CM codes for rarer diseases (PMR, uveitis and scleritis) did not reflect the true clinical problem in a large proportion of our patients. This is particularly true when coding is performed by physicians outside the area of specialty of the diagnosis.

    ABSTRACT: Prospective data to examine the association of homocysteine with age-related macular degeneration (AMD) are limited. We examined the prospective relation of plasma homocysteine level and AMD in a large cohort of apparently healthy women. We evaluated the relationship between baseline levels of plasma homocysteine and incident AMD among 27,479 female health professionals aged 40 years or older. Main outcome measures were total AMD, defined as self-report documented by medical record evidence of an initial diagnosis after randomization, and visually significant AMD, defined as confirmed incident AMD with visual acuity 20/30 or worse attributable to this condition. During an average 10 years of follow-up, a total of 452 cases of AMD, including 182 cases of visually significant AMD, were documented. Women in the highest versus lowest quartile of plasma homocysteine had modestly, but statistically non-significant, increased risks of total AMD (hazard ratio, HR, 1.24, 95% confidence interval, CI, 0.95-1.63; p for trend 0.07) and visually significant AMD (HR 1.41, 95% CI 0.92-2.17; p for trend 0.052) in age- and treatment-adjusted analyses. These prospective data from a large cohort of apparently healthy women do not support a strong role for homocysteine in AMD occurrence.

    ABSTRACT: The prevalence and determinants of sudden vision loss (SVL) are unknown in African Americans (AAs). Since SVL can be cardiovascular disease (CVD)-related and CVD is highly prevalent in AAs, we examined the prevalence of and CVD factors related to self-reported SVL lasting 24 hours or longer in the cohort of AAs enrolled in the Jackson Heart Study (JHS). The study population comprised 5301 participants enrolled from 2000-2004 in the metropolitan area of Jackson, MS, USA. All participants who responded to the question "Have you ever had any sudden loss of vision or blurring, lasting 24 hours or longer?" on the baseline stroke questionnaire were included in the study. We estimated the prevalence of SVL and used regression modeling to identify CVD factors independently related to SVL. A total of 5262 participants were included, of which 63% (3334/5262) were female. The prevalence of SVL was 3.6% (193/5262) overall (4.4% in females and 2.4% in males), and 8.7% (84/965) in patients with diabetes mellitus. Factors independently related to SVL included coronary heart disease (odds ratio, OR, 1.69, 95% confidence interval, CI, 1.12-2.56), cerebrovascular disease (OR 2.81, 95% CI 1.76-4.47), diabetes (OR 2.85, 95% CI 2.05-3.94), hypertension (OR 1.64, 95% CI 1.09-2.45), female sex (OR 1.82, 95% CI 1.24-2.67), and income less than US$50,000 (OR 2.05, 95% CI 1.28-3.30). In this cohort of AAs, self-reported SVL lasting 24 hours or longer was highly prevalent in women and those with diabetes and was independently related to sex, CVD, CVD risk factors and household income.
