AI Article Synopsis

  • Combined vision and hearing loss, or dual sensory impairment, can arise from various genetic conditions, including ciliopathies and mitochondrial DNA disorders.
  • Conditions like Usher syndrome, Bardet-Biedl syndrome, CHARGE, and others are notable causes of this impairment and have specific retinal phenotypes that can aid in diagnosis.
  • The review focuses on the molecular genetics and clinical characteristics of the most prevalent non-chromosomal inherited disorders linked to dual sensory impairment.

Article Abstract

Combined vision and hearing loss, also known as dual sensory impairment, can occur in several genetic conditions, including ciliopathies such as Usher and Bardet-Biedl syndrome, mitochondrial DNA disorders and systemic diseases, such as CHARGE, Stickler, Waardenburg, Alport and Alstrom syndrome. The retinal phenotype may point to the diagnosis of such disorders. Herein, we aim to provide a comprehensive review of the molecular genetics and clinical features of the most common non-chromosomal inherited disorders to cause dual sensory impairment.

The human genome project ushered in a genomic medicine era that was largely unimaginable three decades ago. Discoveries of druggable cancer drivers enabled biomarker-driven gene- and immune-targeted therapy and transformed cancer treatment. Minimizing treatment not expected to benefit, and toxicity-including financial and time-are important goals of modern oncology.

Microbial Contamination of Eye Drops: A Systematic Review and Meta-analysis.

J Patient Saf

March 2025

Department of Biomedical Science, College of Health and Allied Sciences, University of Cape Coast, Cape Coast, Ghana.

Objectives: To profile the array of microbial contaminants of eye drops, both native and non-native to the ocular surface, and associated factors for contamination.

Methods: Potentially relevant studies were retrieved from major bibliographic databases (PubMed, Scopus, and Web of Science). Data were extracted, and study-specific estimates of the contamination rates of topical ophthalmic solutions were combined using meta-analysis to obtain pooled results.

Retrobulbar/intraconal tube placement in patients with glaucoma: Ahmed FP-7 and tube extender case series with 1 year follow-up.

Front Ophthalmol (Lausanne)

February 2025

Department of Ophthalmology, Advanced Eyecare of New York, New York, NY, United States.

Purpose: The Ahmed FP-7 valve is useful in the management of refractory glaucoma. However, this can often have ocular hypertensive phase and subconjunctival fibrosis that can lead to increased medication use and failure. We report how retrobulbar and intraconal plate placement with tube extension can avoid the ocular hypertensive phase, lower intraocular pressure, and reduce medication burden.

Background: Surveys conducted between 2015 and 2022 showed growing concern among European eye care practitioners about myopia management, though adoption of effective strategies varied. This study updates findings from 2024, analysing trends in attitudes and strategies for myopia management across Europe from 2015 to 2024.

Methods: A cross-sectional online survey targeting European eye care practitioners was distributed in multiple languages through professional bodies.

Development and patterning of a highly versatile visual system in spiders.

Proc Biol Sci

March 2025

Department of Biological and Biomedical Sciences, Oxford Brookes University, Gipsy Lane, Oxford OX3 0BP, UK.

Visual systems provide a key interface between organisms and their surroundings, and have evolved in many forms to perform diverse functions across the animal kingdom. Spiders exhibit a range of visual abilities and ecologies, the diversity of which is underpinned by a highly versatile, modular visual system architecture. This typically includes eight eyes of two developmentally distinct types, but the number, size, location and function of the eyes can vary dramatically between lineages.
