Characterization of retinal pigment epithelium layer in healthy and diseased retinas with high‐resolution adaptive optics transscleral flood illumination imaging

Acta Ophthalmologica, Volume 104, Issue 3, Page e277-e291, May 2026.
Abstract Purpose The retinal pigment epithelium (RPE) is critical in the pathophysiology of retinal diseases, such as age‐related macular degeneration. Adaptive optics transscleral flood illumination (AO‐TFI) offers rapid, detailed morphometric characterization of the RPE layer.

Retinal Pigment Epitheliopathy due to Sub‐Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11 ‐Related Phenotype

Clinical Genetics, Volume 109, Issue 5, Page 972-977, May 2026.
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to
