Reproducibility in the identification of retinal positions on serial fundus photographs: Theory and limitations

Acta Ophthalmologica, EarlyView.
Abstract Background Imaging of the retina is accompanied by distortions so that positions in fundus photographs cannot be linearly translated to positions in the retinal fundus. The purpose of this study was to describe an algorithm and evaluate its reproducibility in identifying points on the retina from their representation on serial fundus ...

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

Acta Ophthalmologica, EarlyView.
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.

Prevalence and profile of astigmatism in individuals availing ophthalmic services at Central Regional Referral Hospital, Gelephu, Bhutan: A cross-sectional, hospital-based study

Bhutan Health Journal
Introduction: Astigmatism has been defined as a type of refractive error when parallel rays of light entering the eye are not focused at one point of the retina when accommodation is at rest due to irregular curvature of the cornea or lens surface.

Advances in the genetics of refractive errors: Contributions from the CREAM consortium

Acta Ophthalmologica, EarlyView.
Abstract The Consortium for Refractive Error and Myopia (CREAM) was established in 2011, bringing together an international team of researchers studying more than 30 cohorts. Since its establishment, CREAM has played a pivotal role in research investigating the genetics of myopia and other refractive errors, serving as a key driver of progress in the ...

Review of Retinopathy of Prematurity Management in the Anti‐VEGF Era: Evolving Global Paradigms, Persistent Challenges and Our AI‐Assisted Future

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Retinopathy of prematurity (ROP) remains a major cause of preventable blindness in premature infants worldwide, with increasing incidence due to advancements in neonatal care. Management of ROP has been revolutionised by anti‐vascular endothelial growth factor (anti‐VEGF) treatments.
