Non-exudative OCT findings in neovascular AMD.

In this narrative review we describe the main optical coherence tomography biomarkers appearing in eyes with neovascular age-related macular degeneration (AMD) that do not directly correspond to exudation. We highlight those signs that may mimic exudation and therefore do not require active treatment, such as outer retinal tubulations, pseudocysts, lipid globules, or hyporeflective wedges. Other signs may indicate impending exudation such as hyperreflective foci or shallow irregular retinal pigment epithelium elevation, and therefore should be carefully monitored.

Scan speed affects quantitative optical coherence tomography angiography vascular metrics.

Optical coherence tomography angiography (OCTA) offers the possibility of obtaining objective quantification of retinal vasculature, with increasing utility as biomarkers for both systemic and ocular diseases. However, the differences between different manufacturers and scan settings are still an important limitation, as many parameters could affect vessel quantification. Here we aim to study the influence of scan speed on quantitative vascular parameters using OCTA.

Topographical Quantification of Retinal Fluid in Type 3 MNV and Associations With Short-Term Visual Outcomes.

Purpose: This study aims to quantify the volume of intraretinal fluid (IRF), subretinal fluid (SRF), and subretinal pigment epithelium (sub-RPE) fluid in treatment-naïve Type 3 macular neovascularization (MNV) eyes with age-related macular degeneration (AMD) and to investigate the correlation of these fluid volumes with visual acuity (VA) outcomes at baseline and following antivascular endothelial growth factor (VEGF) treatment.

Design: Retrospective, clinical cohort study.

Methods: In this study, we analyzed patients diagnosed with exudative AMD and treatment-naïve Type 3 MNV undergoing a loading dose of anti-VEGF therapy.

Astigmatism Influences Quantitative and Qualitative Analysis in Optical Coherence Tomography Angiography Imaging.

Purpose: The purpose of this paper was to study the influence of astigmatism in optical coherence tomography angiography (OCTA) images in a quantitative and qualitative analysis.

Methods: This was a prospective, cross-sectional study. We included 110 eyes of 110 patients: 20 eyes without astigmatism and 90 eyes with astigmatism ≥0.

Optical coherence tomography biomarkers in early and intermediate age-related macular degeneration: A clinical guide.

Advanced forms of age-related macular degeneration (AMD), characterised by atrophic and neovascular changes, are a leading cause of vision loss in the elderly population worldwide. Prior to the development of advanced AMD, a myriad of risk factors from the early and intermediate stages of AMD have been published in the scientific literature over the last years. The ability to precisely recognise structural and anatomical changes in the ageing macula, altogether with the understanding of the individual risk implications of each one of them is key for an accurate and personalised diagnostic assessment.
