The role of optical coherence tomography in detecting and correcting stent malapposition during primary percutaneous coronary intervention: A case series and review of current practice

Heart India
Primary percutaneous coronary intervention (PCI) is the gold standard for treating acute myocardial infarction (AMI). Stent malapposition, a complication more common in AMI due to plaque disruption and thrombus burden, increases the risks of stent ...

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.

Retinal capillary density in relation to diabetes duration and levels of glycaemia in young patients with type 1 diabetes

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine retinal capillary plexus characteristics and their correlation with diabetes duration and levels of glycaemia in young type 1 diabetes (T1D) patients. Methods Cross‐sectional analysis of baseline data from an observational, prospective cohort study of 69 patients with T1D aged 6–32 (mean 16) years in T1D duration subgroups ≤

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.

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 ...

Real‐world observational study evaluating metabolic and kidney outcomes in patients living with chronic kidney disease and type 2 diabetes mellitus with obesity prescribed tirzepatide

Diabetic Medicine, EarlyView.
Abstract Background Obesity and type 2 diabetes mellitus (T2DM) accelerate chronic kidney disease (CKD) progression. Tirzepatide, a dual glucagon‐like peptide‐1 (GLP‐1) and glucose‐dependent insulinotropic polypeptide (GIP) receptor agonist, has demonstrated metabolic and potential renoprotective benefits in clinical trials.
