AI Insight
Inherited retinal degenerations are a heterogeneous group of genetic disorders causing progressive vision loss, with pathogenic variants identified in hundreds of genes. This review examines the clinical presentations of these conditions, categorizes them based on which retinal cell types are primarily affected, and discusses emerging therapeutic approaches. Novel treatments under development include gene therapy, cell-based therapies, optogenetic interventions, and retinal implant technologies.
Why it matters
The identification of numerous genetic variants enables more precise diagnosis and personalized treatment strategies for patients with inherited retinal diseases. Emerging therapies offer potential pathways to slow or halt vision loss in conditions that currently have limited treatment options, representing significant progress toward preserving sight in affected individuals.
Understand the Science
Inherited retinal degenerations are a diverse group of genetic disorders that result in progressive vision loss. Advances in genetic testing have revealed pathogenic variants in hundreds of genes, reflecting the remarkable heterogeneity of these conditions and pointing to the complexity of the developmental and homoeostatic processes needed for a lifetime of good vision. This Review summarises the clinical presentation of inherited retinal degenerations, outlines broad disease categories based on the primary type of retinal cell affected, and highlights novel treatment approaches including gene, cell, optogenetic, and implantable chip therapies.
