Deep learning for retinal non-perfusion and foveal avascular zone analysis in wide-field OCTA in diabetic retinopathy.

We developed an automated framework for segmenting low-quality and non-perfusion areas in widefield OCTA images to obtain two key metrics useful for diabetic retinopathy (DR) monitoring: the retinal non-perfusion index (NPI) and foveal avascular zone (FAZ) area. Using 170 images from 88 patients in the EVIRED cohort, we trained two models: Q-NET, which segments low-quality areas, and NPA-NET, which detects non-perfusion areas and the FAZ. Their combined outputs created a 4-class map to calculate NPI and FAZ area.

Efficacy and safety of multiple fluocinolone acetonide implants in diabetic macular oedema: comparison between first and second intravitreal injections.

Purpose: To compare the efficacy and safety between a first and a second injection of fluocinolone acetonide implants (FAc-I) in the treatment of diabetic macular oedema (DMO).

Methods: This retrospective, multicentre cohort study included eyes with chronic DMO that received two consecutive FAc-I injections. We analysed visual and anatomical outcomes, additional DMO treatments, and intraocular pressure (IOP)-related adverse events.

Genetic analysis of participants with foveal hypoplasia.

Introduction: There is few data that investigate the genetic underpinnings of idiopathic foveal hypoplasia and assess its potential overlap with albinism-related gene variants in a cohort devoid of familial albinism history.

Methods: This cross-sectional study included 19 participants diagnosed with idiopathic foveal hypoplasia, confirmed via optical coherence tomography (OCT). We detailed ophthalmic evaluations and genotyping using a panel of 33 genes related to foveal hypoplasia.

Retinal Screening in High-Performance Athletes: A Retrospective Analysis of Asymptomatic Peripheral Lesions in Collision and Non-Collision Sports.

Background: Ocular trauma is a frequent concern among athletes, particularly those involved in collision sports. While overt injuries are well-documented, the prevalence of asymptomatic peripheral retinal lesions resulting from repetitive head or ocular trauma remains underexplored. This study aimed to assess the prevalence of these retinal lesions in elite athletes and to evaluate the potential risk associated with participation in collision sports.

Retinal optical coherence tomography angiography imaging in population studies for study of microvascular dysfunction in Alzheimer's disease and related dementias.

Introduction: Widespread use of retinal optical coherence tomography angiography (OCT-A) imaging requires methodological and analytical consensus to ensure reproducible and accurate results in epidemiological studies on Alzheimer's disease and related dementias (ADRD).

Methods: A consensus framework for assessment of fovea-centered 3 × 3-mm and 6 × 6-mm OCT-A image quality was developed, and reproducibility was reported. Agreement was assessed for overall image quality and image quality relevant for vessel density (VD) quantification and foveal avascular zone (FAZ) metrics.

Surgical Outcomes of Vitrectomy with Gas or Silicone Oil Tamponade for Giant Retinal Tears.

Introduction: The aims of the study were to assess the long-term anatomic and functional outcomes in giant retinal tear (GRT)-associated retinal detachment (GRT-RD) and identify factors associated with recurrence.

Methods: This is a retrospective monocentric study of the patients treated for GRT-RD between 2017 and 2022 at Rothschild Foundation Hospital, Paris, France.

Results: A total of 65 eyes from 64 patients were analyzed with a mean follow-up of 21.

Visual Outcomes after Spontaneous and Surgical Closure of Small Idiopathic Macular Holes: A Comparative Study.

Introduction: Small full-thickness macular holes (FTMHs) are classically treated surgically but can also occasionally close spontaneously. Long-term visual outcomes of spontaneously closed FTMHs are not well described. We compared best-corrected visual acuity (BCVA) after surgical and spontaneous closure of idiopathic FTMH (IMHs) and assessed the effect of IMH size on BCVA.

Applications of artificial intelligence to inherited retinal diseases: A systematic review.

Artificial intelligence(AI)-based methods have been extensively used for the detection and management of various common retinal conditions, but their targeted development for inherited retinal diseases (IRD) is still nascent. In the context of limited availability of retinal subspecialists, genetic testing and genetic counseling, there is a high need for accurate and accessible diagnostic methods. The currently available AI studies, aiming for detection, classification, and prediction of IRD, remain mainly retrospective and include relatively limited numbers of patients due to their scarcity.

Baseline characteristics of the first 302 patients included for acute malignant hypertension crisis in the prospective multidisciplinary HAMA cohort.

Background: Malignant hypertension has not disappeared and remains the most severe form of hypertension. More than 100 years after its description, many points remain unanswered. Mechanisms, definitions, and optimal treatment are still controversial.

CYSTOID MACULAR EDEMA IN BIRDSHOT RETINOCHOROÏDITIS: Long-Term Treatment Study in 142 Patients.

Purpose: To assess the long-term efficacy and safety of treatments for cystoid macular edema in birdshot retinochoroïditis.

Methods: Observational retrospective study of 142 HLA-A29-positive patients with cystoid macular edema; the main outcome was the optical coherence tomography intraretinal cysts resolution.

Results: During the mean follow-up of 75 months (12-178), 61.

Detection of capillary abnormalities in early diabetic retinopathy using scanning laser ophthalmoscopy and optical coherence tomography combined with adaptive optics.

This study tested if a high-resolution, multi-modal, multi-scale retinal imaging instrument can provide novel information about structural abnormalities in vivo. The study examined 11 patients with very mild to moderate non-proliferative diabetic retinopathy (NPDR) and 10 healthy subjects using fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), adaptive optics scanning laser ophthalmoscopy (AO-SLO), adaptive optics OCT and OCTA (AO-OCT(A)). Of 21 eyes of 11 patients, 11 had very mild NPDR, 8 had mild NPDR, 2 had moderate NPDR, and 1 had no retinopathy.

Artificial intelligence-based prediction of diabetic retinopathy evolution (EviRed): protocol for a prospective cohort.

Introduction: An important obstacle in the fight against diabetic retinopathy (DR) is the use of a classification system based on old imaging techniques and insufficient data to accurately predict its evolution. New imaging techniques generate new valuable data, but we lack an adapted classification based on these data. The main objective of the Evaluation Intelligente de la Rétinopathie Diabétique, Intelligent evaluation of DR (EviRed) project is to develop and validate a system assisting the ophthalmologist in decision-making during DR follow-up by improving the prediction of its evolution.

Incidence of macular displacement after rhegmatogenous retinal detachment surgery using ultra-widefield fundus autofluorescence.

Purpose: The incidence of retinal displacement after rhegmatogenous retinal detachment (RRD) surgery is variable and its clinical consequences are unclear. The aim of this study was to assess the incidence and clinical features of retinal displacement after RRD surgery by using ultra-widefield (UWF) imaging.

Methods: Retrospective observational study including all consecutive patients who underwent RRD surgery at the Rothschild Foundation Hospital.

Hybrid Fusion of High-Resolution and Ultra-Widefield OCTA Acquisitions for the Automatic Diagnosis of Diabetic Retinopathy.

Optical coherence tomography angiography (OCTA) can deliver enhanced diagnosis for diabetic retinopathy (DR). This study evaluated a deep learning (DL) algorithm for automatic DR severity assessment using high-resolution and ultra-widefield (UWF) OCTA. Diabetic patients were examined with 6×6 mm2 high-resolution OCTA and 15×15 mm2 UWF-OCTA using PLEX®Elite 9000.

Retinal capillary and choriocapillaris assessment using a beam modifier optical coherence tomography angiography module to increase lateral optical resolution.

Purpose: To assess a new optical coherence tomography angiography (OCTA) technology and its contribution to retinal vascularization and choriocapillaris (CC) exploration.

Methods: A new module, named "Beam expander" (BE), which increases the lateral resolution of OCTA, was used in combination with a prototype software in the PLEX® Elite 9000 Swept-Source OCT instrument (ZEISS, Dublin, CA). This prospective study involved 22 healthy subjects imaged with and without BE.
