Inter‐eye microvascular asymmetry across stages of diabetic retinopathy: An OCT angiography study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate inter‐eye asymmetry in macular microvascular parameters across different stages of diabetic retinopathy (DR) using OCT angiography, and to explore the associations with clinical factors. Methods This cross sectional study included 442 eyes of 221 patients with diabetes mellitus type 2. Central subfield thickness (CST), area

Longitudinal progression of retinal nonperfusion in clinically stable diabetic retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To longitudinally assess and quantify changes in retinal nonperfusion (NP) in clinically stable diabetic retinopathy (DR) using ultra‐widefield fluorescein angiography (UWF‐FA) and optical coherence tomography angiography (OCTA). Methods Fifty‐one eyes from thirty‐three patients were followed for a mean of 15.9 ± 11.4 months.

Concurrent macular neovascularization in shallow irregular retinal pigment epithelium elevation phenotypes in age‐related macular degeneration and chronic central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract This systematic review and meta‐analysis synthesized the reported frequency of concurrent macular neovascularization (MNV) among selected eyes with author‐defined shallow irregular retinal pigment epithelium (RPE) elevations in age‐related macular degeneration (AMD) and chronic central serous chorioretinopathy (CSC).

Optic nerve head blood flow autoregulation during isometric exercise in primary open‐angle glaucoma assessed by laser speckle flowgraphy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess optic nerve head blood flow (ONHBF) autoregulation in patients with early‐ to moderate‐stage primary open‐angle glaucoma (POAG) and age‐ and sex‐matched healthy controls using laser speckle flowgraphy (LSFG) and isometric handgrip exercise.

Correcting Axial Length‐Related Magnification Errors in Optical Coherence Tomography Angiography Improves Machine Learning Classification Performance in High Myopia

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To determine whether axial length‐related magnification correction in optical coherence tomography angiography (OCTA) improves machine learning classification of high myopia and resolves inconsistencies in the values and discriminatory power of OCTA microvascular metrics.

Tattoo Inflammation With Uveitis: From Recognition to Definition

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Tattoo inflammation with uveitis (TIU) is increasingly recognised but growing case numbers have revealed substantial heterogeneity. Patients currently classified as TIU appear to include those with overt or evolving systemic sarcoidosis as well as those with isolated, pigment‐associated ocular inflammation.

Evaluation of the Safety and Therapeutic Range of Nanosecond Laser Treatment in Rabbits

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Subthreshold, nanosecond laser therapy has potential as a treatment for age‐related macular degeneration; however, the therapeutic range and safety profile have not been fully documented. In this study, rabbits were used for a preclinical assessment of nanosecond laser treatment.

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

Diabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...

Research Review: A scoping review exploring the needs, barriers, and facilitators to the collection of biological data in adolescence for mental health research

Journal of Child Psychology and Psychiatry, EarlyView.
Background There is increasing recognition of the challenge of representativeness in data, including economic, social, and ethnic diversity, in biological mental health research. This is a particular challenge in adolescence, where brain and body development are impacted by the environment.
