Aim: This qualitative study explored the lived experiences of the patients with microphthalmia and anophthalmia and their parents, focusing on the healthcare, school settings and daily life challenges to improve patient management.

Methods: In-depth interviews were conducted in Stockholm, Sweden, from October 2022 to June 2023. Participants were recruited through the St Erik Eye Hospital database (2008-2022), and the data was analysed using reflexive thematic analysis.

Article Synopsis
  • Spontaneous bleeds are a major cause of mortality in children with Alagille syndrome (ALGS), particularly affecting girls more than boys, as shown by a systematic review of vascular events.
  • Research using Jag1 mouse models revealed they experienced vascular abnormalities, including brain bleeds and blood vessel issues, which could exacerbate with high blood pressure.
  • Retinography was found to be an effective non-invasive tool for examining vascular characteristics in ALGS patients, highlighting significant sex differences in vascular conditions in this disorder.

Congenital optic disc malformations can cause visual impairment. Diagnostics can be challenging during early infancy and childhood and visual prognosis difficult to predict; optical coherence tomography may be of value. The children often have coexisting comorbidities like pituitary hormone deficiency, neurodevelopmental disorders, and neurological impairments, and evaluation by a pediatrician should be performed.

Brain injuries due to abusive head trauma (AHT) in infants are not rare and they are probably under-diagnosed. Retinal hemorrhages (RH) constitute a cardinal symptom of AHT and AHT is the most common cause of RH in infants next to childbirth. Retinoschisis with or without retinal folds is highly suggestive of AHT and never seen secondary to childbirth.

Non-graft-vs.-host disease (non-GVHD) ocular complications are generally uncommon after hematopoietic cell transplantation (HCT), but can cause prolonged morbidity affecting activities of daily living and quality of life. Here we provide an expert review of non-GVHD ocular complications in a collaboration between transplant physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

Ocular graft-versus-host disease (GVHD) occurs in more than half of patients who develop chronic GVHD after allogeneic hematopoietic cell transplantation (HCT), causing prolonged morbidity, which affects activities of daily living and quality of life. Here we provide an expert review of ocular GVHD in a collaboration between transplant physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Recent updates in ocular GVHD, regarding pathophysiology, preclinical models, risk factors, prevention, screening, diagnosis, response criteria, evaluation measures, and treatment are discussed in this review.

Objective: To study visual pathway pathology detected by visual evoked potentials (VEPs) in patients treated with hematopoietic stem cell transplantation (HSCT) in childhood and to determine the impact of adverse ocular findings, somatic diseases, and conditioning regimens on the VEP results.

Methods: Ophthalmological assessments including pattern VEPs were performed in 47 of 79 patients at a median age of 15 years (range 3-21 years) in median 6 years (1-17 years) after HSCT. Somatic data were extracted from medical records.

Aim: There have been few studies on long-term electroretinographic findings in patients with long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency (LCHADD). This study correlated long-term electroretinographic findings with age, metabolic control and clinical symptoms.

Methods: We examined 12 Swedish patients with LCHADD.

Purpose: To report prevalence, ocular characteristics and coexisting neurological, behavioural, somatic and neuroradiological abnormalities in children and adolescents with morning glory disc anomaly (MGDA).

Methods: In a cross-sectional population-based study, 12 patients with MGDA, aged 2-20 years, were identified. All 12 agreed to ophthalmological assessments including visual functions, refraction, fundus photography, optical coherence tomography (OCT) and ocular motor score (OMS).

Aim: Although cytomegalovirus (CMV) is the most common congenital infection, existing research has not provided us with a full picture of how this can affect children in the future. The aim of this case-control study was to evaluate disabilities in a well-defined group of children with congenital cytomegalovirus (CMV) infection, who had been fitted with cochlear implants because of severe hearing impairment.

Methods: A multidisciplinary team assessed 26 children with congenital CMV infection for balance difficulties, neurodevelopmental disabilities and language and visual impairment.

Purpose: Fanconi anaemia (FA) is a multisystemic disorder with ocular implications. This study aims to describe visual function, ocular characteristics and visual processing skills in patients with FA after haematopoietic stem cell transplantation.

Methods: Ten patients with FA, ages 8-17 years, underwent ophthalmological examinations, corneal, periocular and fundus photography, visual evoked potentials (VEPs), visual fields and ocular motor and visual processing information tests.

Purpose: Ocular motility disturbances are common in a number of neuropaediatric and neurometabolic disorders. Assessment of ocular motor function can be a source of information for diagnosis and follow-up of these patients.

Aim: To evaluate a new clinical ocular motor function test: ocular motor score (OMS) and provide reference values in children and young adults without known ocular or neurological disorders.

The mucopolysaccharidoses (MPS) are a group of rare lysosomal storage disorders characterized by the accumulation of glycosaminoglycans in several tissues and organs. This accumulation results in an array of clinical manifestations and premature death in severe cases. Ocular problems are very common in children with MPS and may involve the cornea, sclera, trabecular meshwork, retina, optic nerve and also the posterior visual pathways.

Purpose: High intraocular pressure (IOP) and glaucoma are often suspected in patients with mucopolysaccharidosis (MPS). To determine corneal hysteresis (CH) and IOP in children with mucopolysaccharidosis I-Hurler (MPS I-H) and MPS VI.

Methods: Clinical measurements with ocular response analyzer (ORA).

Ocular pathology is common in patients with mucopolysaccharidosis (MPS), a hereditary lysosomal storage disorder, where the eye as well as other tissues accumulate excessive amounts of glycosaminoglycans. Despite genetic and phenotypic heterogeneity within and between different types of MPS, the disease symptoms and clinical signs often manifest during the first 6 months of life with increasing head size, recurrent infections, umbilical hernia, growth retardation and skeletal problems. Typical ocular features include corneal clouding, ocular hypertension/glaucoma, retinal degeneration and optic nerve atrophy.
