Aim Methods Results Conclusion Prematurity is a risk factor for strabismus, but the roles of intermediate factors like retinopathy of prematurity (ROP) and neurological lesions are less understood. We aimed to identify neonatal risk factors for strabismus at age 5.5 in preterm children.Data were extracted from the étude épidémiologique sur les petits âges gestationnels 2 cohort, a French prospective population‐based study of preterm children born in 2011 with gestational age of 34 weeks or less. Strabismus was recorded during a medical interview at 5.5 years. Using a directed acyclic graph, intermediate and confounding factors were identified. Total and direct effects of gestational age on strabismus risk were analysed using generalised estimating equation.Among 2419 children assessed, 274 (52.6% male) presented strabismus at 5.5 years. The direct effect of gestational age remained significant after adjustment (p < 0.001). In the complete imputed model: maternal smoking during pregnancy (odds ratio, OR 1.8; 95% confident interval, 95% CI 1.3–2.6), neonatal severe cerebral lesions (OR 2.9, 95% CI 1.8–4.6) and severe ROP (OR 4.2, 95% CI 1.9–9.0) were independent risk factors.Special attention is needed regarding strabismus screening at age 5.5 in preterm children, even without severe cerebral lesions and ROP. Smoking cessation during pregnancy should be encouraged. [ABSTRACT FROM AUTHOR]

Purpose Materials and Methods Results Conclusions To elaborate a deep learning (DL) model for automatic prediction of late recurrence (LR) of rhegmatogenous retinal detachment (RRD) using pseudocolor and fundus autofluorescence (AF) ultra‐wide field (UWF) images obtained preoperatively and postoperatively.We retrospectively included patients >18 years who underwent either scleral buckling (SB) or pars plana vitrectomy (PPV) for primary or recurrent RRD with a post‐operative follow‐up >2 years. Records of RRD recurrence between 6 weeks and 2 years after surgery served as a ground truth for the training of the deep learning (DL) models. Four separate DL models were trained to predict LR within the 2 postoperative years (binary outputs) using, respectively, UWF preoperative and postoperative pseudocolor images and UWF preoperative and postoperative AF images.A total of 412 eyes were included in the study (332 eyes treated with PPV and 80 eyes with SB). The mean follow‐up was 4.0 ± 2.1 years. The DL models based on preoperative and postoperative pseudocolor UWF imaging predicted recurrence with 85.6% (sensitivity 86.7%, specificity 85.4%) and 90.2% accuracy (sensitivity 87.0%, specificity 90.8%) in PPV‐treated eyes, and 87.0% (sensitivity 86.7%, specificity 87.0%) and 91.1% (sensitivity 88.2%, specificity 91.9%) in SB‐treated eyes, respectively. The DL models using preoperative and postoperative AF‐UWF imaging predicted recurrence with 87.6% (sensitivity 84.0% and specificity 88.3%) and 91.0% (sensitivity 88.9%, specificity 91.5%) accuracy in PPV eyes, and 86.5% (sensitivity 87.5%; specificity 86.2%) and 90.6% (sensitivity 90.0%, specificity 90.7%) in SB eyes, respectively. Among the risk factors detected with visualisation methods, potential novel ones were extensive laser retinopexy and asymmetric staphyloma.DL can accurately predict the LR of RRD based on UWF images (especially postoperative ones), which can help refine follow‐up strategies. Saliency maps might provide further insight into the dynamics of RRD recurrence. [ABSTRACT FROM AUTHOR]

Purpose: Distinguishing posterior persistent fetal vasculature (PFV) from retinal detachment (RD) may be very challenging clinically and ultrasonographically, as they share common morphological features. However, it is crucial, considering their substantially distinct management and treatment. We aimed to assess the relevance of quantitative colour Doppler flow imaging to distinguish PFV from RD in children. Methods: This retrospective bi‐centre study included 66 children (30 females and 36 males, mean age: 244 ± 257 days) with a clinically suspected diagnosis of RD or posterior PFV. All children underwent systematic and standardized conventional ultrasonography and colour Doppler flow imaging under general anaesthesia with a qualitative and quantitative analysis of the retrolental tissue's vascularization. Peak systolic velocity, end‐diastolic velocity and resistive index were recorded for analysis. Whenever available, surgical findings were deemed gold standard for diagnosis. A Mann–Whitney U‐test was used to compare quantitative colour Doppler flow imaging data. Results: Peak systolic velocity and end‐diastolic velocity were significantly lower in children with PFV versus RD: 2.7 (IQR: 0.5) versus 5.1 (IQR: 2.8), p < 0.001, and 0.0 (IQR: 0.0) versus 2.0 (IQR: 1.2), p < 0.001, respectively. Resistive index was significantly higher in children with PFV versus RD: 1 (IQR: 0) versus 0.6 (IQR: 0.1), p < 0.001. Area under curves (AUCs) were of 0.94, 0.99 and 1, respectively. No differences between PFV and RD were observed on structural ultrasound or qualitative analysis of colour Doppler. Conclusion: Quantitative colour Doppler flow imaging has an excellent accuracy in distinguishing PFV from RD in children. It may help to improve management and treatment. [ABSTRACT FROM AUTHOR]

This study aims to assess the prevalence and characteristics of preterm infants with retinopathy of prematurity (ROP) treated outside the recommended guidelines. In this retrospective monocentric cohort, we included all premature children treated in our department for ROP by laser photoablation or anti-VEGF intravitreal injection. The main outcome was treatment of both eyes for ROP less severe than pre-threshold type 1, treated outside ETROP guidelines. A total of 114 children received treatment for ROP in our department, among whom 32 (28.1%) children received treatment for indications outside the ETROP guidelines for both eyes. The indications outside the guidelines were persistent stage 2 or 3 ROP that showed no evidence of regression after 41 weeks of corrected gestational age (11 children; 34.4%), pre-plus stage (11; 34.4%), difficulties in disease staging (7; 21.9%), type 2 ROP with plus disease (2; 6.2%), and treatment due to logistical difficulties (1; 3.1%; hospitalized in neonatal units hundreds of miles away from our department, with no fundus examination possible in the neonatal unit). To resume, in our cohort, 28.1% of children received treatment for ROP less severe than pre-threshold type 1 both eyes. The main indications for off-label treatment were the persistence of active ROP during follow-up and the presence of pre-plus-stage disease. Our data suggest the need to update ROP treatment criteria to reflect real-life practices. Additional studies are required in order to evaluate the long-term benefits and side effects of treatments outside the recommended indications, and to establish revised treatment guidelines.
