PURPOSE: To present the recruitment and testing methodology of the National Eye Health Survey (NEHS), a population-based study that aimed to determine the prevalence and causes of vision impairment and blindness in Australia. METHODS: Non-Indigenous Australians aged 50 years and older and Indigenous Australians aged 40 years and older were recruited using a door-to-door approach from 30 randomly selected geographical areas, stratified by remoteness. Participants underwent a vision examination, anterior segment assessment, intraocular pressure testing, perimetry, and fundus photography...

PURPOSE: To examine the association between xanthophyll intake and prevalent early age-related macular degeneration (AMD) using data from the Atherosclerosis Risk in Communities Study (n = 10,295). Potential effect modification by genetic polymorphisms and biomarkers of high-density lipoprotein (HDL) metabolism was explored. METHODS: Xanthophyll intake was assessed at visit 1 (1987-1989) using food frequency questionnaires. Prevalent early AMD was assessed at visit 3 (1993-1995) via retinal photographs...

PURPOSE: To determine the distribution of macular thickness in a healthy Iranian population aged 45-69 years and its association with certain determinants. METHODS: All participants underwent optometric examinations including measurement of uncorrected and corrected visual acuity, objective refraction by retinoscopy, and subjective refraction. Subsequently, all participants underwent slit-lamp biomicroscopy followed by fundus examination through direct and indirect ophthalmoscopy, and optical coherence tomography (OCT) imaging under pupil dilation...

PURPOSE: To evaluate the 4-year incidence and progression of and risk factors for diabetic retinopathy (DR) in an Indian population. METHODS: From a cross-sectional study of 1425 subjects with diabetes, 911 (63.9%) returned for 4-year follow-up. After excluding 21 with ungradable retinal images, data from 890 subjects were analyzed. Participants underwent examinations based on a standard protocol, which included grading of retinal photographs. RESULTS: The incidences of DR, diabetic macular edema (DME), and sight-threatening diabetic retinopathy (STDR) were 9...

PURPOSE: We aimed to evaluate changes in retinal, choroidal, ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL) thicknesses in genetically diagnosed adult patients with familial Mediterranean fever (FMF). METHODS: A total of 50 eyes of 50 genetically diagnosed patients with FMF and 50 eyes of controls were analyzed. Patients were recruited from the Genetic Diagnostic Center of Dışkapı Yıldırım Beyazıt Research and Training Hospital, Turkey.

PURPOSE: Facial palsy (FP) can result in serious ophthalmic sequelae including loss of vision. We describe the clinical characteristics of FP patients presenting for ophthalmologic evaluation and the timing for initiating ophthalmologic care. METHODS: We performed a retrospective review of 96 consecutive FP patients presenting between 1992 and 2015 at a tertiary eye center. The main outcome measures were time interval from the diagnosis of FP and onset of ocular symptoms to the initial ophthalmologic evaluation (IOE), and the severity of exposure keratopathy and eyelid malposition on IOE...

PURPOSE: To evaluate the relationship between retinal vascular caliber and kidney function in a cohort of Australian children and adolescents with type 1 diabetes. METHODS: This was a cross-sectional study of 483 children and adolescents with type 1 diabetes, aged 7-18 years. An audit of medical files of participants who attended the Royal Children's Hospital, Melbourne, between January 2009 and March 2014 was performed. Albumin to creatinine ratio (ACR) was acquired through spot urine samples and microalbuminuria was classified as ACR >3...

PURPOSE: An estimated 19 million children are visually impaired; of these, 1.4 million are irreversibly blind. A key challenge is to identify them early in life to benefit maximally from visual rehabilitation, and/or treatment. This aggregative review and structured literature analysis summarizes evidence of what it is about the key informant (KI) approach that works to identify children with blindness or severe visual impairment (B/SVI) in the community (for whom, to what extent, in what circumstances, in what respect, how and why)...

PURPOSE: We illustrate the effect of survival bias when investigating risk factors for eye disease in elderly populations for whom death is a competing risk. Our investigation focuses on the relationship between smoking and late age-related macular degeneration (AMD) in an observational study impacted by censoring due to death.

PURPOSE: We sought to determine the prevalence of trachoma in 44 Local Government Areas (LGAs) of Kano State, Nigeria. 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...

PURPOSE: To understand the prevalence, awareness, and risk factors for diabetic retinopathy (DR) among Chinese with known type-2 diabetes mellitus (T2DM) in eastern China communities. METHODS: A community-based survey including 913 patients with known T2DM was conducted in Suzhou, China. Diabetes was defined as hemoglobin A1c (hbA1c) ≥6.5%, use of diabetic medication or a physician diagnosis of diabetes. Retinal photographs were graded for the presence of DR using the Airlie House classification system...

PURPOSE: Age-related macular degeneration (AMD) is the leading cause of severe, irreversible vision loss in older adults. Evidence for an association between AMD and mortality remains inconclusive despite evidence for an association with cardiovascular and inflammatory diseases. We aim to compare all-cause, cardiovascular and cancer mortality between those with early or late AMD and control study participants. METHODS: A protocol was registered at PROSPERO (CRD42015020622)...
