Up to 25% of pediatric cataract cases are inherited. There is sparse information in the literature regarding the cost of whole-exome sequencing (WES) for suspected hereditary pediatric cataracts. Molecular diagnosis of suspected hereditary pediatric cataracts is important for comprehensive genetic counseling.

We aimed to identify the reports of symptoms of depression, anxiety, and stress among caregivers of children without visual impairment, with low vision, and with blindness and their relationship with the degree of social, emotional, material, and affective support. This cross-sectional and multicenter study was conducted in the municipality of Rio de Janeiro, Brazil, from 2019 to 2020. A questionnaire was applied to obtain caregivers' sociodemographic and economic data.

Methods: This prospective observational study was conducted in Rio de Janeiro, Brazil, between April 2016 and May 2019.
Hereditary hyperferritinemia-cataract syndrome (HHCS) is a rare, frequently misdiagnosed, autosomal dominant disease caused by mutations in the gene. It causes bilateral pediatric cataract and hyperferritinemia without iron overload. The objective of this case series, describing three Brazilian families, is to increase awareness of HHCS, as well as to discuss possible phenotypic interactions with concurrent mutations in , the gene associated with autosomal recessive inheritance hereditary hemochromatosis.

Children with congenital zika syndrome (CZS) may present a spectrum of neurological impairments with changes in tonus, posture, and movement similar to children with CP. However, the relationship between CZS and hip dysplasia has not been characterized.

Introduction: This study aimed to assess visual acuity (VA) in Congenital Zika Syndrome (CZS)-children to evaluate visual loss. To that end we evaluated 41 CZS - children, from Rio de Janeiro using Teller Acuity Cards.
Methods: To asses VA, we evaluated 41 CZS - children, from Rio de Janeiro using Teller Acuity Cards.
Purpose: To examine the epidemiological characteristics of children undergoing cataract surgery at a referral center in Sao Paulo State, Brazil, as well as the facts surrounding treatment delays.
Methods: In this transversal observational study, 240 operated eyes from 178 children undergoing cataract surgery were reviewed. The following aspects were analyzed: epidemiological and clinical characteristics, parental observations, red reflex test, operated eye, and age at cataract diagnosis and surgery.
Little is known about the impact of congenital Zika virus (ZIKV) exposure on growth in the first years of life. In this prospective cohort study,201 ZIKV antenatally-exposed children were followed at a tertiary referral center in Rio de Janeiro, Brazil. Eighty-seven were classified as congenital Zika syndrome (CZS) patients and 114 as not congenital Zika syndrome (NCZS); growth parameters were described and compared between groups and with WHO standard growth curves.

ROP is one of the leading causes of avoidable childhood blindness worldwide, especially in middle-income countries. The current ROP screening involves indirect binocular ophthalmoscopy (IBO) by ROP expert ophthalmologists.

Methods: These guidelines were developed based on the medical literature and clinical experience of an expert committee. PubMed/Medline searches were performed, with selected publications not restricted to systematic reviews, randomized controlled trials, or observational studies.
Up to 25% of pediatric cataract cases are inherited, with half of the known mutant genes belonging to the crystallin family. Within these, crystallin beta B3 () has the smallest number of reported variants. Clinical ophthalmological and genetic-dysmorphological evaluation were performed in three autosomal dominant family members with pediatric cataract and microphthalmia, as well as one unaffected family member.

We investigated the differences in adverse pregnancy/infant outcomes in two cohorts comprising 114 pregnant women with PCR-confirmed ZIKV infection in Rio de Janeiro, Southeastern Brazil ( = 50) and Manaus, in the north region of the country ( = 64). Prior exposure to DENV was evaluated through plaque reduction neutralizing antibody assays (PRNT 80) and DENV IgG serologies.

Background And Objective: Antenatal Zika virus (ZIKV) or toxoplasmosis infections may present with isolated eye abnormalities with absence of other apparent birth defects. The purpose of this article is to discuss the overlapping spectrum of clinical presentation and retinochoroidal scarring in congenital ZIKV and toxoplasmosis infections.
Patients And Methods: Prenatal ultrasound abnormalities seen from antenatal ZIKV and toxoplasmosis infections overlap and may include intracranial calcifications, microcephaly, and intrauterine growth restriction.
Background: There are limited data on the natural history of antenatal Zika virus (ZIKV) exposure in twin pregnancies, especially regarding intertwin concordance of prenatal, placental, and infant outcomes.
Methods: This prospective cohort study included twin pregnancies referred to a single institution from September 2015 to June 2016 with maternal ZIKV. Polymerase chain reaction (PCR) testing of maternal, placental, and neonatal samples was performed.
We report neurodevelopmental outcomes in 216 infants followed since the time of PCR-confirmed maternal Zika virus (ZIKV) infection in pregnancy during the Rio de Janeiro epidemic of 2015-2016 (refs. ). Neurodevelopment was assessed by Bayley Scales of Infant and Toddler Development, third edition (Bayley-III; cognitive, language and motor domains) in 146 children and through neurodevelopment questionnaires/neurological examinations in 70 remaining children.

The association of prenatal ultrasonographic findings with adverse neonatal outcomes, beyond structural anomalies such as microcephaly, has not been described to date.
Objective: To determine whether prenatal ultrasonographic examination results are associated with abnormal neonatal outcomes in Zika virus-affected pregnancies.
There are limited data on amniocentesis as a diagnostic tool for congenital Zika syndrome. Here we report on a prospective cohort of 16 women with suspected Zika virus infection in a highly endemic area, and discuss the role of amniocentesis in the prenatal diagnosis of fetal Zika infection.

Methods: Infants were examined following the ZIKV outbreak period at Instituto Fernandes Figueira/FIOCRUZ. Visual function was considered abnormal if an infant could not fix and follow a standardized high-contrast target (10 cm) by 3-6 months of age.
Unlabelled: : media-1vid110.1542/5804915134001PEDS-VA_2018-1104 OBJECTIVES: To characterize ophthalmic manifestations of confirmed or suspected antenatal Zika virus (ZIKV) exposure.
Methods: Infants with antenatal ZIKV exposure were referred for evaluation during the 2015-2016 Rio de Janeiro outbreak.
Zika virus (ZIKV) disease has become a global health emergency with devastating effects on public health. Recent evidences implicate the virus as an emergent neuropathological agent promoting serious pathologies of the human nervous system, that include destructive and malformation consequences such as development of ocular and fetal brain lesions, microcephaly in neonates, and Guillain-Barré syndrome (GBS) in adults. These neurological disorders of both central and peripheral nervous systems are thought to be associated to the neurotropic properties of the virus that has ability to infect neural stem cells as well as peripheral neurons, a hallmark of its pathogenicity.

Objective: To evaluate eye findings in a cohort of infants whose mothers had polymerase chain reaction-confirmed Zika virus infection during pregnancy.
Design, Setting, And Participants: In this descriptive case series performed from January 2 through October 30, 2016, infants were examined from birth to 1 year of age by a multidisciplinary medical team, including a pediatric ophthalmologist, from Fernandes Figueira Institute, a Ministry of Health referral center for high-risk pregnancies and infectious diseases in children in Rio de Janeiro, Brazil.
Background: Zika virus (ZIKV) has been linked to central nervous system malformations in fetuses. To characterize the spectrum of ZIKV disease in pregnant women and infants, we followed patients in Rio de Janeiro to describe clinical manifestations in mothers and repercussions of acute ZIKV infection in infants.
Methods: We enrolled pregnant women in whom a rash had developed within the previous 5 days and tested blood and urine specimens for ZIKV by reverse-transcriptase-polymerase-chain-reaction assays.
