OBJECTIVE To study the distribution of congenital/infantile cataract in the entire population of Denmark according to etiological and clinical classifications. DESIGN Population-based cohort study with retrospective chart review. PARTICIPANTS All children (0 to 17 years old) who were born between 1959 and 2001 and registered with congenital/infantile(More)
AIMS To estimate the occurrence of early cataract among patients with Down's syndrome and to evaluate the clinical characteristics of the cases. METHODS Cases with Down's syndrome were ascertained from a cohort of all Danish children between 0 and 17 years of age, who were diagnosed with cataract during the period 1977-2001 (n = 1027). Information on the(More)
PURPOSE Cataract decreases blue light transmission. Because of the selective blue light sensitivity of the retinal ganglion cells governing circadian photoentrainment, cataract may interfere with normal sleep-wake regulation and cause sleep disturbances. The purpose was to investigate the effect of cataract surgery on circadian photoentrainment and to(More)
AIM To study which eye-screening protocol prevails in Swedish maternity/neonatal wards, evaluate efficacy in a prospective study and compare results with earlier Swedish retrospective results. METHODS Surveys were sent in 2006 to maternity/neonatal and women's health departments regarding screening policy. Response frequency was 96% (122/127). Data were(More)
BACKGROUND Little is known about the aetiological factors underlying strabismus. We undertook a large cohort study to investigate perinatal risk factors for strabismus, overall and by subtype. METHODS Orthoptists reviewed ophthalmological records for Danish National Birth Cohort (DNBC) children examined for strabismus in hospital ophthalmology departments(More)
PURPOSE To investigate maternal, demographic, and pre- and perinatal risk factors for idiopathic congenital/infantile (ICI) cataract. METHODS Based on national registries, a cohort of all children born in Denmark and aged 0 to 17 years during 1977 to 2001 was established, and congenital/infantile cataract cases were identified. Cases of unknown/idiopathic(More)
PURPOSE To determine the incidence and cumulative risk of childhood cataract in Denmark during 1980 to 2000. METHODS A cohort of 2,616,439 Danish children born between 1962 and 2000 was followed from 1980 or from the day of birth, whichever occurred later, until their 18th birthday, death, emigration, or diagnosis of cataract, whichever occurred first.(More)
Raviola and Wiesel's monkey eyelid suture studies of the 1970s laid the cornerstone for the experimental myopia science undertaken since then. The aim has been to clarify the basic humoral and neuronal mechanisms behind induced myopization, its eye tissue transmitters in particular. Besides acquiring new and basic knowledge, the practical object of the(More)
PURPOSE To analyse and discuss screening for the detection of congenital cataract in two Nordic countries, Denmark and Sweden. METHODS Until 2011, in Denmark, no guideline concerning screening for congenital cataract existed. Since 2011, Danish guidelines regarding eye examination include examination with a pencil light at age 5 weeks, whereas newborn red(More)
Importance To our knowledge, there have been few population-based studies of strabismus incidence conducted. Our population-based study provides valuable data for health services planning and identifying research needs. Objective To determine the incidence and age distribution of strabismus, overall and by subtype, among children 7 years or younger. (More)
