myopia/nicotine

Tobacco regulation efforts have been criticized by some academic economists for failing to provide adequate welfare-analytic justification. This paper attempts to address these criticisms. Unlike previous research that has discussed second-hand smoke and health care financing externalities, this

OBJECTIVE To investigate prevalence and risk factors for myopia, hyperopia and astigmatism in southern India. METHODS Randomly sampled villages were enumerated to identify people aged ≥40 years. Participants were interviewed for socioeconomic and lifestyle factors and attended a hospital-based

To investigate the association of passive tobacco smoke exposure with early-onset myopia among three-year-old children in Singapore. Pregnant mothers who attended their first trimester clinic at two major maternity units were recruited into the GUSTO birth cohort. The current analysis comprised 572

Despite the high prevalence and public health impact of refractive errors, the mechanisms responsible for ametropias are poorly understood. Much evidence now supports the concept that the retina is central to the mechanism(s) regulating emmetropization and underlying refractive errors. Using a

OBJECTIVE To establish the prevalence, severity, and risk factors for diabetic retinopathy in a representative sample of Victorian residents aged 40 years and older. METHODS A population based, cluster sampling method was used to recruit 4744 participants (86% participation rate). Nine randomly

Purpose: To establish a scoring system to triage patients presenting with symptoms of flashes and floaters to allow safe differentiation between those with retinal tears and detachments, versus uncomplicated posterior vitreous detachments

The eyes are exposed to multiple environmental factors, which affect visual development, comfort, and visual health. While overexposure to sunlight can cause ocular surface and retinal pathologies, insufficient exposure to daylight could significantly contribute to myopia progression. New artificial

This review of recent articles on ocular toxicology concentrates on undesirable effects on the eye induced by systemically used xenobiotics. These effects include the corticosteroid-induced glaucoma and cataracts (especially in children), chloroquine-induced heart block and retinopathy, its possible

OBJECTIVE To evaluate possible risk factors for multiple retinal tears in patients with acute posterior vitreous detachment. METHODS Three hundred and seventy-six consecutive patients presenting with symptoms of floaters and/or flashes were examined. The associations of retinal tears with the

OBJECTIVE Peripheral defocus, higher-order aberrations, and accommodation interact with pupil size to influence retinal image quality and possibly eye growth. Iridectomy (ID) provides a fixed, enlarged pupil. Results from in vitro studies suggest that ID may reduce or eliminate accommodation in the

PurposeTo investigate the association between urinary cotinine levels as an objective biological marker for exposure to nicotine and refractive status.Patients and methodsThis cross-sectional study analyzed data from the Korea National Health and Nutrition Examination Survey between 2008 and 2011. A

OBJECTIVE Motivated by pharmacologic findings linking nicotinic acetylcholine receptors to eye development in chicks, the authors studied whether the refractions of children who were passively exposed to cigarette smoke by their parents differed from those of nonexposed children. METHODS A

OBJECTIVE To evaluate the link between primary open-angle glaucoma (POAG) and potential genetic and environmental risk factors. METHODS A case/control study was carried out using 175 POAG patients and 175 controls, all Caucasians of at least 40 years of age. The diagnosis of POAG was established
