Best's macular dystrophy (BMD) usually manifests with visual failure in the first or second decade of life; however, there is a large variability in expressivity of the disease, and some patients have no manifestation other than a pathological electro-oculogram (EOG). Autosomal dominant Best's vitelliform macular dystrophy (AD-BVMD) has a very specific phenotype that varies with the stage of the disease. In recent years, the authors have seen description of another clinical entity known as autosomal recessive BMD...

OBJECTIVES: Recent research has shown that concentric contact lenses (CLs) can be a way to control the progression of myopia. The purpose of the current study was to compare vision-related quality-of-life measures in children wearing distance single-vision (SV) spectacles versus MiSight CLs, a specific concentric design for myopia control. METHODS: Subjects aged 8 to 12 with myopia from -0.75 to -4.00 diopters (D) of sphere and astigmatism less than 1.00 D of cylinder were allocated to the lenses study group (MiSight) or control group (SV)...

Autism spectrum disorders (ASDs) are neurodevelopmental conditions characterized by impairments in social/communication abilities and restricted behaviors. The present study aims to examine color vision discrimination in ASD children and adolescents without intellectual disability. The participants were also subdivided in order to compare color vision thresholds of autistic participants and those who achieved diagnostic criteria for Asperger Syndrome (AS). Nine subjects with autism, 11 participants with AS and 36 typically developing children and adolescents participated in the study...

BACKGROUND: Hearing and vision impairments/problems are associated with increased risk of premature mortality in adulthood. One potential pathway explaining this association is reduced levels of physical activity. Reductions in activity levels due to sensory impairments may commence earlier in life; however, associations between sensory impairments/problems and activity levels in childhood are not well understood. OBJECTIVE: The objective of this study was to examine associations between hearing and vision problems and objectively measured activity levels in a representative sample of British children...

BACKGROUND: Vernal kerato-conjunctivitis (VKC) is an infrequent but serious form of allergic conjunctivitis common in warm and humid areas where air is rich in allergens. It affects both eyes asymmetrically. Although VKC is a self-limiting disease but visions affecting corneal complications influence the quality of life in school children. The aim of this study was to list the corneal complications due to this condition and to find out the extent of visual impairment among VKC patients...

BACKGROUND: Preparticipation physical examinations (PPEs) are required for children and adolescents before sports participation to identify at-risk athletes. These evaluations can be completed in a traditional office-based setting or in a station-based format. It is unclear if one format is superior to the other in identifying at-risk athletes. METHODS: We performed a retrospective chart review of children and adolescents between the ages 10 and 18 years who received their PPE in our office or in a station-based setting in a local high school between the years 2009 and 2015...

BACKGROUND: Congenital nasolacrimal duct obstruction (NLDO) is a common condition causing excessive tearing in the first year of life. Infants present with excessive tearing or mucoid discharge from the eyes due to blockage of the nasolacrimal duct system, which can result in maceration of the skin of the eyelids and local infections, such as conjunctivitis, that may require antibiotics. The incidence of nasolacrimal duct obstruction in early childhood ranges from 5% to 20% and often resolves without surgery...

INTRODUCTION: Fixational saccades are miniature eye movements that constantly change the gaze during attempted visual fixation. Visually guided saccades and fixational saccades represent an oculomotor continuum and are produced by common neural machinery. Patients with strabismus have disconjugate binocular horizontal saccades. We examined the stability and variability of eye position during fixation in patients with strabismus and correlated the severity of fixational instability with strabismus angle and binocular vision...

REVIEW
Tero T Kivelä, Theodora Hadjistilianou
From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary...

PURPOSE: There are no commercially available devices to measure visual fields in infants. We developed a device, "Pediatric Perimeter," that quantifies visual field extent (VFE) for infants. We describe the construction, validation, and use of this device. METHODS: A hemispherical dome with light emitting diodes (LEDs) was constructed. The LEDs were controlled using a computer program to measure reaction time (RT) to gross visual fields (GVF) and the VFE. Participants were tested in supine position in a dark room...

Tourette syndrome (TS) is a childhood-onset chronic disorder characterized by the presence of multiple motor and vocal tics. This study investigated the alterations of spontaneous brain activities in children with TS by resting-state functional magnetic resonance imaging (rs-fMRI). We obtained rs-fMRI scans from 21 drug-naïve and pure TS children and 29 demographically matched healthy children. The amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF) and regional homogeneity (ReHo) of rs-fMRI data were calculated to measure spontaneous brain activity...

Anatomical segmentectomy is an advantageous procedure because it spares healthy lung that has potential to show compensatory growth after lung resection and decreases the risk of air leak and residual resection, which becomes a problem in wedge resection. However, anatomical segmentectomy has not become a common procedure in pediatrics because it requires more complicated procedure than lobectomy or wedge resection, especially in patients with a history of pulmonary infection. In this case report, anatomical basal segmentectomy was safely performed with magnified vision by a hybrid video-assisted thoracic surgery (VATS) approach in a 6-year-old girl with intralobar pulmonary sequestration after severe pneumonia...

An eye tracking experiment explored the gaze behavior of deaf individuals when perceiving language in spoken and sign language only, and in sign-supported speech (SSS). Participants were deaf (n = 25) and hearing (n = 25) Spanish adolescents. Deaf students were prelingually profoundly deaf individuals with cochlear implants (CIs) used by age 5 or earlier, or prelingually profoundly deaf native signers with deaf parents. The effectiveness of SSS has rarely been tested within the same group of children for discourse-level comprehension...

Adaptive methods provide quick and reliable estimates of sensory sensitivity. Yet, these procedures are typically developed for and applied to the non-chemical senses only, i.e., to vision, audition, and somatosensation. The relatively long inter-stimulus-intervals in gustatory studies, which are required to minimize adaptation and habituation, call for time-efficient threshold estimations. We therefore tested the suitability of two adaptive yes-no methods based on SIAM and QUEST for rapid estimation of taste sensitivity by comparing test-retest reliability for sucrose, citric acid, sodium chloride, and quinine hydrochloride thresholds...

Childhood glaucoma poses a diagnostic and therapeutic challenge to ophthalmologists. Difficulty in examination and limitations on ability to perform structural and functional testing of optic nerve make diagnosis and verification of glaucoma control difficult in children. It is well known that an excessive loss of hyperopia is a useful sign in alerting the examining ophthalmologist to the possible diagnosis of glaucoma. We present an interesting case of juvenile onset glaucoma presenting with anisohypermetropic amblyopia in one eye and normal vision in the fellow eye that has glaucoma...

The aim of this study was to compare postural stability in a group of preterm-born children aged 4-6 years old and in a group of age-matched full-term control children by exploring both spatial and temporal analysis of the Center of Pressure (CoP). Twenty-nine children born prematurely (mean age: 5.38±0.17) and twenty-nine age-matched full-term control children participated in this study. Postural control was tested on both a stable and an unstable platform (from Framiral(®)) in three different visual conditions: eyes open fixating a target, eyes closed, and with vision perturbed by optokinetic stimulation...
