Purpose: To report on the occurrence of postoperative visual axis opacification (VAO) in children younger than 5 years of age operated for cataract in Sweden, and to analyse correlations with age at surgery and surgical method.
Methods: Data were derived from the Swedish Pediatric Cataract Register (PECARE). All children operated on between 1 January 2007 and 31 December 2020 were included.
Aim: Analysis of age at time of detection and surgery of dense unilateral cataract and investigation of best-corrected visual acuity (BCVA) in a nationwide register-based cohort study, based on the routine of maternity ward eye screening.
Methods: Data were derived from the Paediatric Cataract Register (PECARE). All children (n = 54) diagnosed with dense congenital unilateral cataract between January 2007 and September 2014 who had surgery before 1 year of age, and for whom 5-year follow-up records were available, were included.
PECARE: Parental Feedback to Improve Congenital Cataract Care in Sweden.
J Pediatr Ophthalmol Strabismus
September 2022
Purpose: To analyze non-directed parental feedback to health care providers responsible for pediatric cataract care in Sweden.
Methods: A directed content analysis was used to analyze data consisting of text representing free comments provided by 40 parents. A deductive approach was employed by applying the model of balancing the child's inability and ability, which includes the categories mastering, collaborating, facilitating, and adapting.
Purpose: The aim was to report cumulative incidence and time of onset of postoperative glaucoma in a paediatric early cataract surgery cohort.
Methods: Data were retrieved from the Pediatric Cataract Register (PECARE), a prospective register of Swedish cataract operations before 8 years of age. All eyes with surgery between January 2007 and December 2014 and a registered follow-up were included.
Purpose: To analyze the incidence of adrenal suppression and the glucocorticoid (GC) dose per kilogram body weight given in infants treated with standard protocol for topical ophthalmic GCs after congenital cataract surgery.
Design: Retrospective, consecutive case series.
Participants: All children younger than 2 years of age who underwent operation for congenital cataract between January 2011 and May 2015 in 1 center.
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.
Aim: To report basic epidemiological data concerning surgically treated childhood cataract in Sweden and Denmark.
Methods: Data were derived from the Paediatric Cataract Register (PECARE), a binational, web-based surgical register representing Sweden and Denmark. All children operated before 8 years of age between 1 January 2007 and 31 December 2013 were included.
Purpose: To compare the long-term effect on circadian photoentrainment and sleep in patients implanted with neutral and blue-blocking intraocular lenses 1 year after cataract surgery.
Methods: Randomized, controlled trial involving 67 patients with age-related cataract. Intervention was cataract surgery with implantation of either a neutral or a blue-blocking intraocular lens (IOL).
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 determine any difference between blue-blocking and neutral intraocular lenses (IOLs).

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 reflex examination using a handheld ophthalmoscope is routine protocol in Swedish maternity wards.
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 research is to reduce the burden of human myopia around the world.

Methods: We included all children (aged 0 to 17 years) who during the time period of 1977 to 2005 underwent pediatric cataract surgery in Denmark, excluding cataract cases caused by trauma, or acquired systemic or acquired ocular pathology, and cases with ocular anomalies associated with the development of retinal detachment. Cases of cataract were ascertained from the mandatory Danish National Patient Register, and information on retinal detachment was based on medical chart review.
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).
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 or by ophthalmologists in private practice.
In a prospective, population-based cohort study, the authors investigated the effect of in-utero exposure to maternal smoking and consumption of alcohol, coffee, and tea on the risk of strabismus. They reviewed medical records for children in the Danish National Birth Cohort identified through national registers as possibly having strabismus. Relative risk estimates were adjusted for year of birth, social class, maternal smoking, maternal age at birth, and maternal coffee and tea consumption.

Methods: A population-based cohort of all children in Denmark aged 0 to 17 years during the period 1977 to 2001, who underwent surgery for pediatric cataract, was established by retrospective chart review. Glaucoma cases were defined as those in which glaucoma surgery (trabeculectomy and/or diode laser transscleral cyclophotocoagulation) was performed and/or permanent medical therapy prescribed after cataract surgery.
Purpose: To report central nervous system involvement after varicella zoster virus infection.
Methods: We evaluated the frequency and type of neurological complications in patients initially presenting with ophthalmic herpes zoster at an ophthalmological department in a Danish university hospital, over a 7-year period.
Results: Of the 110 immunocompetent patients who presented with initial ophthalmic zoster, six (5.
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 cause were included in the study.
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 cataract in Denmark during the period 1977 to 2001.
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. Cases were ascertained from the Danish National Register of Patients (NRP) and validated by reviewing the medical records.
