This study assessed challenges faced by researchers with the informed consent process (ICP). In-depth interviews were used to explore challenges encountered by Investigators, Research assistants, Institutional Review Board members and other stakeholders. An electronic questionnaire was also distributed, consisting of Likert-scale responses to questions on adherence to the ICP, which were derived from the Helsinki Declaration and an informed consent checklist of the US Department of Health and Human Research (HSS).

This study evaluated patient experiences with genetic testing for inherited retinal diseases (IRDs) and the association between underlying knowledge, testing outcomes, and the perceived value of the results. An online survey was distributed to adults with IRDs and parents/guardians of dependents with IRDs who had had genetic testing. Data included details of genetic testing, pre- and post- test perceptions, Decision Regret Scale, perceived value of results, and knowledge of gene therapy.

Internal medicine (IM) resident physicians spend a considerable amount of time managing their inbox as part of their longitudinal continuity clinic experience. There are no standardized guidelines for how programs should train, monitor, or supervise residents in this type of patient care. To understand how IM residency programs educate, monitor, and supervise resident electronic health record (EHR) inbox management as part of their longitudinal continuity clinic and determine whether patient safety events have occurred due to EHR inbox-related patient care decisions made by unsupervised resident physicians.

To assess the transcriptomic profile of disease-specific cell populations, fibroblasts from patients with primary open-angle glaucoma (POAG) were reprogrammed into induced pluripotent stem cells (iPSCs) before being differentiated into retinal organoids and compared with those from healthy individuals. We performed single-cell RNA sequencing of a total of 247,520 cells and identified cluster-specific molecular signatures. Comparing the gene expression profile between cases and controls, we identified novel genetic associations for this blinding disease.

Article Synopsis
  • A significant number of family members with Leber hereditary optic neuropathy (LHON) who have a risk variant do not experience vision loss, indicating a low penetrance of the condition.
  • Mitochondrial haplotypes are crucial in determining the likelihood of vision loss related to LHON, with specific variants being common in the general population.
  • The paper discusses findings that suggest a correlation between certain mitochondrial subclades and reduced risk of severe vision impairment, while addressing points raised in a related research publication.

Objective: Paediatric (childhood or congenital) cataract is an opacification of the normally clear lens of the eye and has a genetic basis in at least 18% of cases in Australia. This study aimed to replicate clinical gene screening to identify variants likely to be causative of disease in an Australian patient cohort.

Methods And Analysis: Sixty-three reported isolated cataract genes were screened for rare coding variants in 37 Australian families using genome sequencing.

Article Synopsis
  • * In a study of 58 individuals from 44 families, genetic testing achieved a likely diagnosis in 70.5% of cases, especially among those with a family history or previous corneal graft surgery.
  • * The research also uncovered eight new gene variants and five families with syndromic conditions related to corneal dystrophies, emphasizing the importance of genetic testing for better clinical outcomes.

There are currently no treatments for geographic atrophy, the advanced form of age-related macular degeneration. Hence, innovative studies are needed to model this condition and prevent or delay its progression. Induced pluripotent stem cells generated from patients with geographic atrophy and healthy individuals were differentiated to retinal pigment epithelium.

The first individualized therapy was administered in the United States just 2 years ago, when milasen, a therapeutic adapted from a Food and Drug Administration (FDA)-approved antisense oligonucleotide technology, was developed for a young girl with an extremely rare genetic mutation associated with Batten disease. Since then there has been an explosion of enthusiasm in developing customized treatments for extremely rare genetic conditions. These interventions raise some of the ethics concerns characteristic of novel therapeutics while simultaneously challenging existing legal, regulatory, and ethical understandings.

We conducted an updated epidemiological study of Leber hereditary optic neuropathy (LHON) in Australia by using registry data to establish the risk of vision loss among different LHON mutations, sex, age at onset, and mitochondrial haplogroup. We identified 96 genetically unrelated LHON pedigrees, including 56 unpublished pedigrees, and updated 40 previously known pedigrees, comprising 620 affected individuals and 4,948 asymptomatic carriers. The minimum prevalence of vision loss due to LHON in Australia in 2020 was one in 68,403 individuals.

There were eighteen Research Ethics Committees (RECs) operating in Ghana as of December 2019 but no empirical assessment of their operational characteristics had been conducted. We assessed the characteristics of Ghanaian RECs using an existing Self-Assessment Tool for RECs in Developing Countries. We present results from nine RECs that participated in this nation-wide assessment.

This document provides consensus-based recommendations for general physicians and primary care physicians who diagnose and manage patients with mitochondrial diseases (MD). It builds on previous international guidelines, with particular emphasis on clinical management in the Australian setting. This statement was prepared by a working group of medical practitioners, nurses and allied health professionals with clinical expertise and experience in managing Australian patients with MD.

: Home-based videogame treatments are increasingly popular for amblyopia treatment. However, at-home treatments tend to be done in short sessions and with frequent disruptions, which may reduce the effectiveness of binocular visual stimulation. These treatment adherence patterns need to be accounted for when considering dose-response relationships and treatment effectiveness.

Leber hereditary optic neuropathy (LHON) is one of the most common primary mitochondrial diseases. It is caused by point mutations in mitochondrial DNA (mtDNA) genes and in some cases, it can result in irreversible vision loss, primarily in young men. It is currently unknown why LHON mutations affect only some carriers and whether bioenergetic compensation enables unaffected carriers to overcome mitochondrial impairment and preserve cellular function.

Autosomal dominant optic atrophy (ADOA) is a neuro-ophthalmic condition characterized by bilateral degeneration of the optic nerves. Although heterozygous mutations in OPA1 represent the most common genetic cause of ADOA, a significant number of cases remain undiagnosed.Here, we describe a family with a strong ADOA history with most family members spanning three generation having childhood onset of visual symptoms.

Purpose: Developmental abnormalities of the ocular anterior segment in some cases can lead to ocular hypertension and glaucoma. CPAMD8 is a gene of unknown function recently associated with ocular anterior segment dysgenesis, myopia, and ectopia lentis. We sought to assess the contribution of biallelic CPAMD8 variants to childhood and juvenile open-angle glaucoma.

Nanophthalmos and posterior microphthalmos are ocular abnormalities in which both eyes are abnormally small, and typically associated with extreme hyperopia. We recruited 40 individuals from 13 kindreds with nanophthalmos or posterior microphthalmos, with 12 probands subjected to exome sequencing. Nine probands (69.
