Leber hereditary optic neuropathy is characterized by bilateral, painless loss of vision in children and young adults (generally up to 25 years old). Since its first description in 1871, the understanding of its etiology and pathogenesis has improved considerably. The article considers Leber neuropathy from the points of view of ophthalmology, neurology and molecular genetics, and presents data on experimental treatment methods, one of which is undergoing clinical trial.

BACKGROUND: Globally, complications of prematurity are the leading cause of death in children under five. Preterm infants who survive their first month of life are at greater risk for various diseases and impairments in infancy, childhood and later life, representing a heavy social and economic burden for families, communities and health and social systems. Kangaroo mother care (KMC) is recommended as a beneficial and effective intervention for improving short- and long-term preterm birth outcomes in low- and high-income settings...

BACKGROUND: Endemic Burkitt's lymphoma is found predominantly in malaria holoendemic zones, typically in the tropical rain forest of Africa. It usually presents as an extra-nodal tumour in children and young adults with predilection for jaws and soft tissues of the abdomen. Clinical features depend on the primary tumour site, extent of the disease and histologic subtype. Acute blindness as a presentation sign is rare. CASE PRESENTATION: A 13 year old African female presented to our facility with a 3 week history of painful abdominal distention, and loss of vision of the left eye...

Macular corneal dystrophy (MCD) is an autosomal recessive hereditary disease. In most cases, various mutations in carbohydrate sulfotransferase 6 (CHST6) gene are the main cause of MCD. These mutations lead to a defect in keratan sulfate synthesis. Retinitis pigmentosa (RP) is another eye disorder with nyctalopia as its common symptom. It has been shown that more than 65 genes have been implicated in different forms of RP. Herein, we report on a 9-member family with 2 girls and 5 boys. Both parents, one of the girls and one of the boys had normal eye vision and another boy had keratoconus...

BACKGROUND AND AIMS: Astonishing drawing capacities have been reported in children with early visual impairments. However, most of the evidence relies on single case studies. Hitherto, no study has systematically jointly investigated, in these children, the role of (1) the severity of the visual handicap, (2) age and (3) practice in drawing. The study aimed at revealing the specificities of the drawing in children deprived from vision, as compared to children with less severe visual handicap and to sighted children performing under haptic or usual visual control...

PURPOSE: To quantify the improvements in visual performance for both distance and near tasks attained by children with bilateral chorioretinal coloboma (CRC) with use of low-vision aids (LVAs). METHODS: This was a hospital-based, cross-sectional, interventional case series of children with bilateral CRC. Demographic data were collected through a structured questionnaire and review of medical records. Distance and near best-corrected visual acuity, contrast sensitivity, and reading speed were evaluated with refractive correction alone and with the use of LVAs (Keplerian telescopes for distance; handheld magnifiers and a tinted lens [400 nm filter] for near)...

Introduction and Objectives: Open dismembered pyeloplasty has been the gold standard treatment for ureteropelvic junction obstruction in children. Laparoscopic pyeloplasty (LP) is becoming a standard procedure, but its acceptance is slow. We report our method for minilaparoscopy (MLP) in children using a tansperitoneal approach with the patient in the lateral flank decubitus which we found technically advantageous. Materials and Methods: Retrospective review of the records of 52 children and adolescents up to 18 years of age who underwent transperitoneal MLP at our institution during March 2012-October 2017 A 5 mm trocar is placed for the camera at the site of the umblicus by open technique, two 3 mm trocars placed in the upper and lower quadrants of the abdomen...

Neuronal ceroid lipofuscinoses (NCLs) are a group of fatal, inherited lysosomal storage disorders mostly affecting the central nervous system of children. Symptoms include vision loss, seizures, motor deterioration and cognitive decline ultimately resulting in premature death. Studies in animal models showed that the diseases are amenable to gene supplementation therapies, and over the last decade, major advances have been made in the (pre)clinical development of these therapies. This mini-review summarises and discusses current gene therapy approaches for NCL targeting the brain and the eye...
