Purpose: The purpose of this study was to investigate the clinical role of multi-signal quantitative optical coherence tomography angiography (OCTA) perfusion sampling in neovascular age-related macular degeneration (AMD).
Methods: The study was designed as a cross-sectional case series. We collected data from already treated macular neovascularization (MNV), characterized by (I) clinically relevant recurrent exudation, (II) nonclinically relevant recurrent exudation, and (III) inactive lesion.
Purpose: The optimal management of pediatric traumatic macular holes (TMH) is unclear from lack of prospective randomized trials. The literature is divided into early (≤1month post-trauma), delayed (>1 month) pars plana vitrectomy (PPV), and observation. Our aim is to find which group can achieve best-superior spectacle corrected visual acuity (VA), visual gain, and time for hole closure.

Methods: Observational, cross-sectional, multicenter study. All patients underwent best corrected visual acuity (BCVA) measurement, OCT (Spectralis HRA + OCT, Heidelberg Engineering) and OCTA (OCT DRI Topcon Triton, Topcon Corporation).
Our purpose is to review the closure time and optical coherence tomography (OCT) biomarkers that result in the non-surgical repair of idiopathic full-thickness macular holes (IFTMH). Our methodology consisted of a comprehensive literature review of the nonsurgical resolution of IFTMH followed by the calculation of the estimated closure time using the structural equation model. Forty-nine studies were found eligible yielding 181 eyes with IFTMH: 81.

Methods: Optical coherence tomography (OCT) was performed in the study eye before and after PBM.
Results: A patient with drusenoid pigment epithelium detachment (D-PED) underwent PBM.
Purpose: To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD).
Methods: This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented.
Purpose: To perform an unsupervised machine learning clustering of patients with punctate inner choroidopathy (PIC) and provide new insights into the significance of pachychoroid disease features in PIC eyes.
Methods: Retrospective multicenter study, including 102 eyes from 82 patients diagnosed with PIC. Demographics, clinical data, and multimodal imaging, including fundus photography, optical coherence tomography, and indocyanine green angiography, were collected.

Background: Vascular endothelial growth factor (VEGF) is a significant modulator of ocular angiogenesis, including that of neovascular age-related macular degeneration (nAMD). Intravitreal injection of anti-VEGF is the benchmark treatment for most retinal vascular diseases, including nAMD, diabetic maculopathy, and macular edema secondary to retinal venous occlusion. Anti-VEGF treatment is a high-frequency, time-consuming, non-cost-effective therapy, especially in countries and regions with limited resources.

Smartphone eye examination may represent a promising tool in the technological spectrum, with special interest for primary health care services. Obtaining fundus imaging with this technique has improved and democratized the teaching of fundoscopy, but in particular, it contributes greatly to screening diseases with high rates of blindness.
View Article and Find Full Text PDFPurpose: The development of optical coherence tomography angiography (OCTA) has radically changed the diagnostic assessment of the intraretinal vascular network. Two different OCTA acquisition modalities have recently been introduced in clinical practice, namely high-resolution (HR) and high-speed (HS) scans. HR OCTA requires more acquisition time and provides higher quality data, whereas HS OCTA is faster but furnishes lower quality data.

However, visual acuity and visual field tests are essentially subjective and, especially in the late stages of the disease, are unable to confidently reveal minor progression.

Herein, we report the multimodal imaging findings of ARB presenting with cystoid maculopathy and investigate the short-term response to combined systemic and topical carbonic anhydrase inhibitors (CAIs).
Material And Methods: An observational, prospective, case series on two siblings affected by ARB is presented.
Purpose: To report a case of Pigmented Paravenous Chorioretinal Atrophy (PPCRA) associated with a novel dominant variant.
Methods: Case report. The patient underwent multimodal retinal imaging, including spectral-domain optical coherence tomography (OCT), OCT Angiography (OCTA), blue-light autofluorescence (BAF), and ultra-widefield pseudocolor retinography and autofluorescence.
Purpose: This study assesses the repeatability of quantitative autofluorescence (qAF) in a multicenter setting and evaluates qAF as the end point for clinical trials in recessive Stargardt disease 1 (STGD1).
Methods: A total of 102 patients with STGD1 underwent qAF imaging as part of the Stargardt Remofuscin Treatment Trial (STARTT; EudraCT No. 2018-001496-20).
Introduction: Photobiomodulation (PBM) represents a potential treatment for non-exudative age-related macular degeneration (AMD). PBM uses wavelengths of light to target components of the mitochondrial respiratory chain to improve cellular bioenergetic outputs. The aim of this study was to further investigate the effects of PBM on clinical, quality of life (QoL) and anatomical outcomes in subjects with intermediate stage non-exudative AMD.

Purpose: To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH).
Methods: By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS).
