Evaluating the impact of polycythemia vera on retinal and optic nerve head microvascularity: An OCTA study

Indian Journal of Ophthalmology
Purpose: This study aims to assess the impact of polycythemia vera (PV) on retinal and optic nerve head (ONH) vessel density (VD) parameters, macular ganglion cell complex (mGCC) thickness, and retinal nerve fiber layer (RNFL) thickness compared to ...

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence ‐ OMEGA report 3

Acta Ophthalmologica, EarlyView.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age‐related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify the GA area in a monocentric study.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Order and complexity measures in OCTA

, 2022
Order and complexity measures in OCTA. Examples include boundingboxes, fillcolors, and shapes as (distinction) features. Clicking a stimulus leads to the octa code used to generate it.I created this figure for the paper titled "The Order & Complexity ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Radial outer retina reflectivity (RORR) sign in LAMP2‐associated retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To describe the radial outer retina reflectivity (RORR) sign in patients carrying pathogenic variants in the X‐linked lysosome‐associated membrane protein‐2 (LAMP2) gene and to review the histologic characteristics of LAMP2 expression in the human retina.
