[PMID: 38878959 DOI: 10.1016/j.jaapos.2024.103956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 02/26/2024] [Accepted: 03/21/2024] [Indexed: 07/07/2024]
Abstract
PURPOSE To determine whether extremely premature infants require screening for retinopathy of prematurity (ROP) if <31 weeks' postmenstrual age (PMA). METHODS The medical records of infants born in community hospital settings at <31 weeks' gestational age (GA) were reviewed retrospectively. Prevalence and progression of ROP in infants born at <24 weeks' GA were compared with infants born at 24-30 weeks' GA. RESULTS A total of 2,061 records were reviewed: 1,969 infants were born at 24-30 weeks' GA; 92, at <24 weeks. Infants born <24 weeks' GA were more likely to develop pre-plus and plus disease or require treatment than infants born 24-30 weeks' GA (P < 0.0001) and did so earlier (P = 0.0001). Eight infants developed pre-plus or greater ROP <31 weeks' PMA; 6 were born <24 weeks' GA. Three infants developed plus disease or required treatment <31 weeks' PMA, the earliest at 27 and 3/7 weeks. CONCLUSIONS Clinicians should consider initiating ROP screening examinations before 31 weeks' PMA, particularly for infants born <24 weeks' GA and those with lower birth weights.

Abstract
PURPOSE To assess the safety and efficacy of ripasudil for retinopathy of prematurity (ROP). STUDY DESIGN Phase 1/2, multicenter, open-label, single-arm, 12-week clinical trial. METHODS Infants born with gestational age (GA) of ≤ 32 weeks or weight of ≤ 1500 g with zone I or II, ≥ stage 1, ROP in both eyes were enrolled. Ripasudil eye drops were administered to patients in both eyes. Phase 1 was a dose-escalation study (once daily for 1 week, then twice daily for 2 weeks); an additional dosing up to 9 weeks was allowed if no safety issues occurred. In phase 2, ripasudil was administered twice daily for up to 12 weeks. Adverse events were assessed. The proportion of patients with type 1 ROP progression, number of days for type 1 ROP progression, and progression to the most advanced ROP stage were estimated. RESULTS Twenty-four infants were enrolled (phase 1, n = 3; phase 2, n = 21). Nineteen and four patients experienced systemic and ocular adverse events, respectively. Efficacy endpoints were not different between the ripasudil and historical control groups. However, in the GA ≤ 27 weeks subgroup, fewer patients progressed to type 1 ROP in the ripasudil than in the historical control group (P = 0.09). In the GA ≤ 27 weeks subgroups, the 25th percentile for the number of days for type 1 ROP progression was 22 days in the historical control group and 44 days in the ripasudil group. CONCLUSION Ripasudil was safe and inhibited/delayed type 1 ROP progression, especially in infants with short GA.

[PMID: 38841619 PMCID: PMC11147992 DOI: 10.1007/s13167-024-00363-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 04/17/2024] [Indexed: 06/07/2024]
Abstract
Purpose Retinopathy of prematurity (ROP) is a retinal vascular proliferative disease common in low birth weight and premature infants and is one of the main causes of blindness in children.In the context of predictive, preventive and personalized medicine (PPPM/3PM), early screening, identification and treatment of ROP will directly contribute to improve patients' long-term visual prognosis and reduce the risk of blindness. Thus, our objective is to establish an artificial intelligence (AI) algorithm combined with clinical demographics to create a risk model for ROP including treatment-requiring retinopathy of prematurity (TR-ROP) infants. Methods A total of 22,569 infants who underwent routine ROP screening in Shenzhen Eye Hospital from March 2003 to September 2023 were collected, including 3335 infants with ROP and 1234 infants with TR-ROP among ROP infants. Two machine learning methods of logistic regression and decision tree and a deep learning method of multi-layer perceptron were trained by using the relevant combination of risk factors such as birth weight (BW), gestational age (GA), gender, whether multiple births (MB) and mode of delivery (MD) to achieve the risk prediction of ROP and TR-ROP. We used five evaluation metrics to evaluate the performance of the risk prediction model. The area under the receiver operating characteristic curve (AUC) and the area under the precision-recall curve (AUCPR) were the main measurement metrics. Results In the risk prediction for ROP, the BW + GA demonstrated the optimal performance (mean ± SD, AUCPR: 0.4849 ± 0.0175, AUC: 0.8124 ± 0.0033). In the risk prediction of TR-ROP, reasonable performance can be achieved by using GA + BW + Gender + MD + MB (AUCPR: 0.2713 ± 0.0214, AUC: 0.8328 ± 0.0088). Conclusions Combining risk factors with AI in screening programs for ROP could achieve risk prediction of ROP and TR-ROP, detect TR-ROP earlier and reduce the number of ROP examinations and unnecessary physiological stress in low-risk infants. Therefore, combining ROP-related biometric information with AI is a cost-effective strategy for predictive diagnostic, targeted prevention, and personalization of medical services in early screening and treatment of ROP.

Visual impairment burden in retinopathy of prematurity: trends, inequalities, and improvement gaps. Eur J Pediatr 2024; 183:1891-1900. [PMID: 38319404 DOI: 10.1007/s00431-024-05450-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/10/2024] [Accepted: 01/22/2024] [Indexed: 02/07/2024]
Abstract
Retinopathy of prematurity (ROP) is an important cause of avoidable childhood visual impairment, and the increase in number and survival of premature infants may inflate its burden globally. We aimed to comprehensively assess the trends and inequalities in the burden of ROP-related visual impairment and to identify improvement gaps to facilitate appropriate actions in neonatal care systems. We obtained ROP data from the Global Burden of Disease 2019 study. We employed joinpoint regression analysis to assess the trends of the burden of ROP-related visual impairment, measured by age-standardised prevalence rates, health equity analysis methods to evaluate cross-country burden inequalities, and data envelopment and stochastic frontier analyses to identify improvement gaps based on the development status, i.e., sociodemographic index (SDI). Between 1990 and 2019, the age-standardised prevalence rates of ROP-related visual impairment significantly increased worldwide (average annual percentage change: 0.23 [95% confidence interval, 0.21-0.26] among males and 0.26 [0.25-0.27] among females), primarily in developed regions. Although significant SDI-related cross-country inequalities were identified, these reduced over time (slope index of inequality: -57.74 [-66.22 to -49.25] in 1990 to -29.68 [-38.39 to -20.97] in 2019; health concentration index: -0.11 [-0.13 to -0.09] in 1990 to -0.07 [-0.09 to -0.06] in 2019). Notably, some less-developed countries exhibited superior performance despite limited resources, whereas others with a higher SDI delivered lagging performance. Conclusion: The global burden of ROP-related visual impairment has steadily increased between 1990 and 2019, with disproportionate burden concentration among less-developed countries, requiring appropriate preventive and intervention measures. What is Known: • Retinopathy of prematurity (ROP) is an important cause of avoidable childhood visual impairment. • The prevalence of ROP is anticipated to increase due to the growing number of extremely premature infants. What is New: • The prevalence of ROP-related visual impairment has increased worldwide, primarily in developed regions, with declining but persisting cross-country inequalities. • The increasing burden of ROP-related visual impairment should be considered as part of global and national health agendas, requiring interventions with proven efficacy.

The Incidence and Timing of Treatment-Requiring Retinopathy of Prematurity in Nanopremature and Micropremature Infants in the United States: A National Multicenter Retrospective Cohort Study. Ophthalmol Retina 2024; 8:279-287. [PMID: 37838276 DOI: 10.1016/j.oret.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 09/17/2023] [Accepted: 10/03/2023] [Indexed: 10/16/2023]
Abstract
PARTICIPANTS This article includes 7293 infants (14 586 eyes) screened for ROP across 5 centers in the United States (Austin Retina Associates, Austin, TX; Bascom Palmer Eye Institute, Miami, FL; Beaumont Eye Institute, Royal Oak, MI; Massachusetts Eye and Ear, Boston, MA; and Stanford Byers Eye Institute, Stanford, CA). PURPOSE To analyze the incidence and timing of treatment requiring retinopathy of prematurity (ROP) in extremely small premature infants. We hypothesize that the smaller the infant by gestational age and birthweight, the higher their likelihood of requiring treatment for ROP. DESIGN Premature infants screened for Retinopathy of Prematurity from 2002-2022 were divided into cohorts based on the following criteria based on gestational age (GA) and birth weight (BW). "Micropremature infants" are infants born between 24-26 weeks GA and between 600-799 g BW. "Nanopremature infants" are born ≤ 24 weeks GA and ≤ 600 g BW. METHODS Retrospective chart review. MAIN OUTCOME MEASURES The incidence and timing of treatment-requiring ROP. RESULTS We found that infants defined as nanopremature had a ∼63% chance of requiring treatment at an average postmenstrual age (PMA) of 36.6 weeks, whereas those defined as micropremature had a 30% chance of requiring treatment at an average PMA of 36.3 weeks. This significantly contrasts with the risk of all screened babies for ROP where the risk of requiring treatment was 8.5%. CONCLUSION Micropremature and nanopremature infants are significantly more likely to require treatment for ROP. With demographic data matched to all 5 major US regions spanning the last decade, these results have the potential to inform neonatologists, pediatricians, and ophthalmologists of an important shift in the landscape of prematurity in the United States.

Abstract
OBJECTIVE To evaluate Retinopathy of Prematurity (ROP) rate and risk factors in a large cohort of preterm newborns. METHODS Single center retrospective study. All preterm inborn hospitalized at the Neonatal Intensive Care Unit of the Policlinico of Catania from January 1, 2009 till December 31, 2018, were included. ROP stage and location, treatments required, maternal and infant risk factors were evaluated. RESULTS Medical records of 898 preterms were retrospectively examined (mean gestational age 32.9 ± 2.3 weeks). Of them 149 (16.6 %) developed bilateral ROP (92 stage 1, 44 stage 2 and 13 stage 3); 66 (7.3 %) received bilateral laser treatment. Six eyes of three patients affected by zone I ROP 1, with plus persistence 15 days after an optimal laser treatment, also received intravitreal ranibizumab injection. Risk factors for ROP development were gestational age (GA) (p < 0.001), birthweight (p < 0.001), assisted ventilation duration (p < 0.001), multiple birth (p = 0.003), erythropoietin (EPO) administration (p = 0.005) and persistence of tunica vasculosa lentis. The decision-tree analysis showed gestational age as the most significant predictive factor (P < 0.001); secondary predictive factors were EPO administration (p = 0.001) in newborns 29-31 weeks GA and birthweight lower than 2090 g (p < 0.001) in 32-34 weeks GA; in this latter group patent ductus arteriosus (PDA) was a tertiary predictive factor (p = 0.043). CONCLUSIONS In our study ROP incidence was 16,6 %; 7.3 % of the patients required laser treatment. Besides well-known factors, such as GA and birthweight, other factors like duration of assisted ventilation, EPO, multiple births, PDA, tunica vasculosa lentis persistence should be considered to tailor ophthalmic evaluation and follow-up.

Abstract
PURPOSE To delineate racial differences in the incidence and time course of ROP in a large cohort of premature infants. METHODS The secondary analysis of data from the two Postnatal Growth and ROP Studies (G-ROP-1 and G-ROP-2) that were collected in 41 hospitals in North America from 2006 to 2017. According to self-reported maternal race, premature infants were classified into 3 groups: White (N = 5580), Black (N = 3252), and Asian (N = 353). Incidence, severity, and time course of ROP; plus disease; and postnatal weight gain rate were compared among racial groups. RESULTS Black infants had significantly smaller BW (mean 1035 vs. 1131 vs.1144 grams, P < .001) and lower GA (28.2 vs. 28.6, vs. 29.1 weeks, P < .001) than White and Asian infants. However, Black infants had lower incidences of severe ROP (11.1% vs. 12.4% vs. 11.9%), ROP (42.1% vs. 43.2% vs. 30.6%), and plus disease (3.6% vs. 6.3%, vs. 5.9%) than White and Asian infants (BW and GA adjusted risk ratio for Black vs. White 0.69 for severe ROP, 0.83 for ROP, 0.44 for plus disease, all P < .0001). Mean daily-weight-gain on days of life 11-20 and 21-30 were similar across groups (P > .05), but lower in Black and Asian infants on days 31-40 (P < .001). There were no differences in the timing of severe ROP and ROP across racial groups. CONCLUSIONS Despite relatively lower GA, BW, and daily-weight-gain, Black preterm infants had lower incidences of ROP and plus disease than White preterm infants. The mechanisms for these differences require further investigation.

Abstract
BACKGROUND Anemia and retinopathy of prematurity (ROP) are common comorbidities experienced by preterm infants, yet the role of anemia on the pathogenesis of ROP remains unclear. Reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR) is a sensitive technique for estimating the gene expression changes at the transcript level but requires identification of stably expressed reference genes for accurate data interpretation. This is particularly important for oxygen induced retinopathy studies given that some commonly used reference genes are sensitive to oxygen. This study aimed to identify stably expressed reference genes among eight commonly used reference genes in the neonatal rat pups' retina upon exposure to cyclic hyperoxia-hypoxia, anemia, and erythropoietin administration at two age groups (P14.5 and P20) using Bestkeeper, geNorm, and Normfinder, three publicly available, free algorithms, and comparing their results to the in-silico prediction program, RefFinder. RESULTS The most stable reference gene across both developmental stages was Rpp30, as predicted by Genorm, Bestkeeper, and Normfinder. RefFinder predicted Tbp to be the most stable across both developmental stages. At P14.5, stability varied by prediction program; at P20, RPP30 and MAPK1 were the most stable reference genes. Gapdh, 18S, Rplp0, and HPRT were predicted as the least stable reference genes by at least one of the prediction algorithms. CONCLUSION Expression of Rpp30 is the least affected by experimental conditions of oxygen induced retinopathy, phlebotomy induced anemia and erythropoietin administration at both timepoints of P14.5 and P20.

Abstract
PURPOSE To evaluate the diagnostic accuracy of the wide-field digital retinal imaging (WFDRI) for the detection of Retinopathy of Prematurity (ROP) in premature infants as compared to the binocular indirect ophthalmoscopy (BIO). METHODS This systematic review and meta-analysis included the publications searched through PubMed (Medline), EMBASE, Scopus, Web of Science, Cochrane Library databases and Clinical Trials. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2, the hierarchical summary receiver operating characteristic, meta-regression, publication bias analyses, and the GRADE methodology for the certainty of the overall evidence were conducted. The pooled effect sizes of the sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and diagnostic odds ratio (DOR) were calculated. RESULTS Total sixteen eligible studies from 10 articles were included with total 2,537 image interpretations from 697 premature infants. Less than 50% risk of bias and low concern were found in each domain across all articles by QUADAS-2. The pooled effect sizes showed the sensitivity of 0.77 (95% confidence interval (C.I.): 0.69-0.84), specificity of 0.96 (95% C.I.: 0.92-0.98), PLR of 20.9 (95% C.I.: 10.2-42.5), NLR of 0.23 (95% C.I.: 0.17-0.33) and DOR of 89 (95% C.I.: 43-185) as compared to BIO. The income level, setting, mean/median birth weight and gestational age contributed to the significant differences in sensitivity (p < 0.001). No publication bias was found among these 16 studies. The GRADE quality of evidence showed moderate for the pooled sensitivity and high for the pooled specificity. CONCLUSIONS The diagnostic accuracy based on WFDRI is substantial and comparable to BIO, supporting its application in the ROP screening programs.

Abstract
Retinopathy of prematurity (ROP) is among the most common causes of childhood blindness. Three phases of ROP epidemics have been observed worldwide since ROP was first described in the 1940s. Despite advances in neonatal care, the occurrence of ROP and associated visual impairment has been increasing somewhere on Earth and remains difficult to control. Conventional treatment options for preventing ROP progression include retinal ablation using cryotherapy or laser therapy. With the emergence of anti-vascular endothelial growth factor (anti-VEGF) treatment for ocular diseases, the efficacy and safety of anti-VEGF therapy for ROP have recently been actively discussed. In the advanced stage of ROP with retinal detachment, surgical treatment including scleral buckling or vitrectomy is needed to maintain or induce retinal attachment. At this stage, the visual outcome is usually poor despite successful anatomical retinal attachment. Therefore, preventing ROP progression by timely screening examinations and treatment remains the most important part of ROP management.

Abstract
PURPOSE To focus on the longitudinal evaluation of high-risk infants for the development of retinopathy of prematurity (ROP) at a single tertiary neonatal intensive care unit (NICU), and to evaluate evolving demographics of ROP and the transition of treatment-warranted disease. DESIGN Retrospective cohort study. METHODS A consecutive retrospective review was performed of all infants screened for ROP between 1990 and 2019 at the Jackson Memorial Hospital neonatal intensive care unit. All inborn infants meeting a birth criteria of <32 weeks' gestational age (GA) or a birthweight (BW) of 1500 g were included. Longitudinal demographic, diagnostic, and treatment data were reported. RESULTS Between January 1, 1990, and June 20, 2019, a total of 25,567 examinations were performed and 7436 patients were included. Longitudinal trends over 3 decades demonstrated a decreasing incidence of ROP (P < .05). Although the mean BW and GA increased over 3 decades, patients with ROP demonstrated lower BW and GA over time (P < .05). The prevalence of micro-premature infants (as defined by BW <750 g) continues to rise over time. Micro-preemies demonstrated increasing severity of zone and stage grading, plus disease, and propensity to require treatment (P < .05). The rate of progression of ROP to stage 4 and 5 disease has decreased over time, and there has been an associated increased adoption of intravitreal bevacizumab as primary and salvage therapy. CONCLUSIONS Understanding the evolution of ROP infants and treatment over time is critical in identifying high-risk infants and in reducing the incidence of severe-stage ROP. Micro-prematurity is one of the significant risk factors for treatment-warranted ROP that continues to increase as neonatal care improves.

Abstract
Importance Congenital viral infections leading to ocular abnormalities are frequent and devastating. As ophthalmological manifestations of COVID-19 in newborns are still unknown, it is important to clarify if SARS-CoV-2 could be associated with ocular abnormalities. Objective To determine whether exposure to SARS-CoV-2 is associated with outcomes in the eyes of newborns. Design, Setting, and Participants This case series enrolled newborns from April to November 2020 from 3 different maternity hospitals in São Paulo, Brazil. The diagnosis of COVID-19 in mothers and newborns was based on real-time reverse transcriptase-polymerase chain reaction assays with material obtained from oronasopharyngeal swab sample; positive IGM serology was also considered as a diagnostic test for mothers. Newborns were excluded if they had any evidence of another congenital infection. All infants underwent external ocular examination and binocular indirect ophthalmoscopy. Exposures Serology test for COVID-19 and detection of SARS-CoV-2 from oronasopharyngeal specimen using a real-time reverse transcriptase-polymerase chain reaction assay on both mothers and newborns. Main Outcomes and Measures Screening for ophthalmologic manifestation in newborns after maternal COVID-19 infection. Results A total of 165 newborns (age range at examination, 1 to 18 days) were evaluated. Of these, 123 (74.5%) were born at full term, and 42 (25.4%) were born preterm. Maternal gestational age at the time of COVID-19-positive test varied from first to 40th gestational weeks. Six newborns (3.6%) had positive polymerase chain reaction findings for SARS-CoV-2. One newborn tested positive within 18 days (horizontal transmission), and 5 newborns tested positive in the first day of life (possible vertical transmission). None had ocular abnormalities. Concerning exposed newborns with negative test results, 1 presented with venous engorgement and vascular tortuosity, 7 had intraretinal hemorrhages, and 2 were diagnosed as having retinopathy of prematurity. Conclusions and Relevance In this uncontrolled case series of Brazilian newborns of mothers with COVID-19 infection, a low rate of COVID-19 infection was found among newborns, and none had ocular abnormalities. Additional controlled studies may be warranted to confirm these findings.

Abstract
BACKGROUND AND OBJECTIVES Retinopathy of prematurity (ROP) is the leading avoidable and treatable cause of childhood blindness in the United States. The objective of this study was to evaluate trends of ROP screening, incidence, and treatment in US NICUs over the last 11 years. METHODS Using standardized data submitted by NICUs from US Vermont Oxford Network member hospitals from 2008 to 2018 on very low birth weight infants hospitalized at the recommended age for ROP screening, we assessed trends in the proportion of eligible infants who received ROP screening, incidence, and treatment of ROP using logistic regression models. RESULTS This study included 381 065 very low birth weight infants at 819 US NICUs participating in Vermont Oxford Network. Over time, more eligible infants received ROP screening (89% in 2008 to 91% in 2018, trend P < .001). Among those screened, overall ROP (stages 1-5, 37% in 2008 to 32% in 2018), severe ROP (stages 3-5, 8% in 2008 to 6% in 2018), and retinal ablation (6% in 2008 to 2% in 2018) declined and anti-vascular endothelial growth factor injections (1% in 2012 to 2% in 2018) increased (all trend P < .001). CONCLUSIONS Among US hospitals from 2008 to 2018, the proportion of ROP screening among infants hospitalized at the recommended age increased, less overall and severe ROP were reported, less retinal ablation was performed, and more anti-vascular endothelial growth factor treatment was used. Despite increased ROP screening over time, 10% of infants were not screened, representing an opportunity for improvement in health care delivery.

Abstract
This brief review examines 1) patterns of intermittent hypoxemia in extremely preterm infants during early postnatal life, 2) the relationship between neonatal intermittent hypoxemia exposure and outcomes in both human and animal models, 3) potential mechanistic pathways, and 4) future alterations in clinical care that may reduce morbidity. Intermittent hypoxemia events are pervasive in extremely preterm infants (<28 weeks gestation at birth) during early postnatal life. An increased frequency of intermittent hypoxemia events has been associated with a range of poor neural outcomes including language and cognitive delays, motor impairment, retinopathy of prematurity, impaired control of breathing, and intraventricular hemorrhage. Neonatal rodent models have shown that exposure to short repetitive cycles of hypoxia induce a pathophysiological cascade. However, not all patterns of intermittent hypoxia are deleterious and some may even improve neurodevelopmental outcomes. Therapeutic interventions include supplemental oxygen, pressure support and pharmacologic drugs but prolonged hyperoxia and pressure exposure have been associated with cardiopulmonary morbidity. Therefore, it becomes imperative to distinguish high risk from neutral and/or even beneficial patterns of intermittent hypoxemia during early postnatal life. Identification of such patterns could improve clinical care with targeted interventions for high-risk patterns and minimal or no exposure to treatment modalities for low-risk patterns.

Abstract
PURPOSE Premature birth, race, and sex are contributing risk factors for retinopathy of prematurity (ROP) and have long-term impact on children's retinal structure. Few studies investigate impact of race and sex on macular structure in children born preterm. This study compared foveal structure in preterm and full-term children. METHODS Children aged 4-18 years were enrolled into three groups: (1) ROP-risk group (n = 81), born at < 32 weeks gestational age with and without history of ROP; (2) preterm group (n = 46), born at 32-36 weeks gestational age; and (3) control group (n = 68) with full-term birth. Using spectral-domain optical coherence tomography volume-scan images, foveal structure within 1-mm and 3-mm early treatment diabetic retinopathy study circular grid was measured and segmented. Total inner and outer retina thickness of the right eye was compared among the three groups. RESULTS The mean total foveal thickness (in microns) was 287 ± 26 for the ROP-risk group, 276 ± 19 for the preterm group, and 263 ± 20 for the control group (F = 26, p < 0.001). Foveal thickness of the ROP-risk group was significantly higher than that of the preterm group and the control group (all p < 0.05). Foveal thickness was thinner in black children than in white children and thinner in females than in males (all p < 0.001). A similar disparity in race and sex was found in the thickness of the inner and outer layers. CONCLUSIONS The fovea was significantly thicker in the ROP-risk group than the control group. Foveal thickness decreases with increased gestational age. Race and sex are significant factors in foveal structure in children.

Abstract
OBJECTIVES Childhood blindness from retinopathy of prematurity (ROP) is increasing as a result of improvements in neonatal care worldwide. We evaluate the effectiveness of artificial intelligence (AI)-based screening in an Indian ROP telemedicine program and whether differences in ROP severity between neonatal care units (NCUs) identified by using AI are related to differences in oxygen-titrating capability. METHODS External validation study of an existing AI-based quantitative severity scale for ROP on a data set of images from the Retinopathy of Prematurity Eradication Save Our Sight ROP telemedicine program in India. All images were assigned an ROP severity score (1-9) by using the Imaging and Informatics in Retinopathy of Prematurity Deep Learning system. We calculated the area under the receiver operating characteristic curve and sensitivity and specificity for treatment-requiring retinopathy of prematurity. Using multivariable linear regression, we evaluated the mean and median ROP severity in each NCU as a function of mean birth weight, gestational age, and the presence of oxygen blenders and pulse oxygenation monitors. RESULTS The area under the receiver operating characteristic curve for detection of treatment-requiring retinopathy of prematurity was 0.98, with 100% sensitivity and 78% specificity. We found higher median (interquartile range) ROP severity in NCUs without oxygen blenders and pulse oxygenation monitors, most apparent in bigger infants (>1500 g and 31 weeks' gestation: 2.7 [2.5-3.0] vs 3.1 [2.4-3.8]; P = .007, with adjustment for birth weight and gestational age). CONCLUSIONS Integration of AI into ROP screening programs may lead to improved access to care for secondary prevention of ROP and may facilitate assessment of disease epidemiology and NCU resources.

Abstract
Retinopathy of prematurity (ROP), a vascular proliferative disease affecting preterm infants, is a leading cause of childhood blindness. Various studies have investigated the pathogenesis of ROP. Clinical experience indicates that oxygen levels are strongly correlated with ROP development, which led to the development of oxygen-induced retinopathy (OIR) as an animal model of ROP. OIR has been used extensively to investigate the molecular mechanisms underlying ROP and to evaluate the efficacy of new drug candidates. Large clinical trials have demonstrated the efficacy of anti-vascular endothelial growth factor (VEGF) agents to treat ROP, and anti-VEGF therapy is presently becoming the first-line treatment worldwide. Anti-VEGF therapy has advantages over conventional treatments, including being minimally invasive with a low risk of refractive error. However, long-term safety concerns and the risk of late recurrence limit this treatment. There is an unmet medical need for novel ROP therapies, which need to be addressed by safe and minimally invasive therapies. The recent progress in biotechnology has contributed greatly to translational research. In this review, we outline how basic ROP research has evolved with clinical experience and the subsequent emergence of new drugs. We discuss previous and ongoing trials and present the candidate molecules expected to become novel targets.

Abstract
PURPOSE To report the changes in incidence and risk factors of retinopathy of prematurity (ROP) in extremely low birth weight (ELBW) infants over a 15-year period in South China. METHODS The medical records of ELBW infants were retrospectively reviewed through established database of Shenzhen Screening for ROP Cooperative Group. The incidence and severity of ROP were compared among three successive 5-year periods (P1: 2004-2008, P2: 2009-2013, P3: 2014-2018). Gestational age, birth weight, plurality, mode of delivery and gender were analyzed as risk factors for ROP in ELBW infants. RESULTS Among the 1099 included ELBW infants, 557 (50.7%) had ROP, and 328 (29.9%) had severe ROP. The highest incidence of ROP (87.5%) and severe ROP (82.5%) were seen in P1. From P2 to P3, the incidence of ROP and severe ROP increased from 45.9% to 50.3% for ROP (P < .05) and from 26.4% to 28.3% for severe ROP (P < .05), respectively. Multivariate logistic regression analysis found only gestational age has a significant effect on the incidence of ROP and severe ROP. CONCLUSIONS From 2004 to 2018, the incidence of ROP and severe ROP in ELBW infants in South China was 50.7% and 29.9%, respectively. Controlling for the other risk factors, only gestational age was statistically associated with ROP in ELBW infants.

Abstract
PURPOSE To determine trends in retinopathy of prematurity (ROP) in a Colorado cohort between 2006 and 2017 and compare trends in risk factors between our cohort and statewide data. METHODS A retrospective cohort study was conducted by the use of records from two registry databases: 1) an academic center's ROP registry, and 2) vital statistics birth data from the Colorado Department of Public Health and Environment (CDPHE). ROP was categorized as severe (type 1 or type 2), low grade (not type 1 or type 2), or no ROP. Other variables included in the analyses were gestational age and birth weight at delivery, and infant mortality. Trends over time were evaluated for both registry databases using generalized linear models. RESULTS In our ROP registry cohort of 1,267 eligible infants, 134 (10.6%) developed severe ROP and 279 (22%) developed low-grade ROP. We found no overall trend in severe ROP rates (p = .23), and a decreasing trend in rates of low-grade ROP (p < .01) over the study period. Trends in gestational age, birth weight, and mortality rates remained stable during the study period in both the ROP registry and the CDPHE cohorts. CONCLUSION The rate of severe ROP in our ROP registry cohort did not change over time. There was evidence of a decreasing trend in low grade ROP during the 12-year study period that was not explained by a change in the primary ROP risk factors in either the ROP registry cohort or the Colorado statewide data.

Abstract
In the twentieth century, a conspicuous lack of effective treatment strategies existed for managing several retinal disorders, including age-related macular degeneration; diabetic retinopathy (DR); retinopathy of prematurity (ROP); retinitis pigmentosa (RP); uveitis, including Behçet's disease; and vitreoretinal lymphoma (VRL). However, in the first decade of this century, advances in biomedicine have provided new treatment strategies in the field of ophthalmology, particularly biologics that target vascular endothelial growth factor or tumor necrosis factor (TNF)-α. Furthermore, clinical trials on gene therapy specifically for patients with autosomal recessive or X-linked RP have commenced. The overall survival rates of patients with VRL have improved, owing to earlier diagnoses and better treatment strategies. However, some unresolved problems remain such as primary or secondary non-response to biologics or chemotherapy, and the lack of adequate strategies for treating most RP patients. In this review, we provide an overview of the immunological mechanisms of the eye under normal conditions and in several retinal disorders, including uveitis, DR, ROP, RP, and VRL. In addition, we discuss recent studies that describe the inflammatory responses that occur during the course of these retinal disorders to provide new insights into their diagnosis and treatment.

Abstract
Retinopathy of prematurity is a major cause of childhood blindness worldwide. Hence, exploring the proper treatment methods is a must in tacking this disease. qRT-PCR and western blot were used to detect the expression of genes and proteins, respectively. The proliferation of human retinal vascular endothelial cells (HRECs) was ensured by MTT assay. The luciferase activity was measured through luciferase assay. The inverted phase-contrast light microscope was used to observe the formation of a vascular tube. In the present study, our data demonstrated that circPDE4B was downregulated, while hypoxia-inducible factor-1α (HIF-1α) and VEGFA were upregulated in the retinopathy of prematurity model in vitro and in vivo. CircPDE4B increasing remarkably inhibited the expression of HIF-1α and VEGFA in hypoxia-induced HRECs and subsequent repressed cell proliferation and pathological angiogenesis. We further found that miR-181c suppressed the expression of von Hippel-Lindau (VHL), while circPDE4B could promote VHL expression via binding to miR-181c. Finally, our results revealed that circPDE4B inhibited the expression of VEGFA and pathological angiogenesis via facilitating VHL-mediated ubiquitin degradation of HIF-1α. In conclusion, circPDE4B suppressed the expression of VEGFA and pathological angiogenesis via promoting VHL-mediated ubiquitin degradation of HIF-1α through binding to miR-181c. Our study indicated that circPDE4B might be an effective therapeutic target of retinopathy of prematurity.

Abstract
PURPOSE To survey current oxygen management, screening criteria, and methods for treating retinopathy of prematurity (ROP) in sub-Saharan Africa. METHODS An online survey was sent to ophthalmologists and neonatologists practicing in sub-Saharan Africa. RESULTS Ophthalmologists and neonatologists from 15 of 49 countries (31%) in sub-Saharan Africa responded. Neonatologists reported treating a median of 15 infants with supplemental oxygen per week but only had a median of 3.5 oxygen-measuring devices and a median of zero oxygen blenders in their units. Ophthalmologists reported screening a median of 5 infants per week for ROP and treating 2 infants each month for ROP. Most ophthalmologists (24/27 [89%]) had access to anti-vascular endothelial growth factor drugs to treat ROP, but only 13 of 27 (48%) had access to a laser. CONCLUSIONS Survey results reveal an urgent need for additional oxygen- management equipment in hospitals in sub-Saharan Africa.

Abstract
Purpose The purpose of this study was to evaluate neurodevelopmental outcomes in 18-month old (corrected age) preterm infants who received an intravitreal bevacizumab (IVB) injection for the treatment of type 1 retinopathy of prematurity (ROP). Methods In this ten-year retrospective study, we reviewed the medical records of patients who underwent ROP screening at Kyushu University Hospital. Among the patients who received IVB or laser photocoagulation (LPC) for the treatment of type 1 ROP, we included infants whose neurodevelopmental examination (the Kyoto Scale of Psychological Development [KSPD]) results at 18 months corrected age were available. Then, the effect of IVB on the developmental quotient (DQ) in each KSPD domain (Postural-Movement, Cognitive-Adaptive, or Language-Social domain) or the overall DQ was investigated by performing linear regression analysis. Results Out of the 513 patients reviewed, 53 were included in the study. IVB and LPC were performed for 14 and 39 patients, respectively. Administration of IVB was significantly associated with neurodevelopmental delay in the Language-Social domain (p = 0.01). The observed association remained even after adjusting for gestational age and birth weight (p = 0.03). Conclusions Administration of IVB may introduce a risk of developmental impairment of interpersonal relationships, socializations, and/or verbal abilities of preterm children. We recommended that preterm infants who received IVB undergo a neurodevelopmental reassessment during their school years or in adulthood.

Abstract
Purpose This study aims at exploring alterations of major metabolites and metabolic pathways in retinopathy of prematurity (ROP) infants and identifying biomarkers that may merit early diagnosis of ROP. Methods We analyzed targeted metabolites from 81 premature infants (<34 weeks of gestational age), including 40 ROP cases (15 males and 25 females, birth weight 1.263 ± 0. 345 kg, gestational age 31.20 ± 4.62 weeks) and 41 cases (30 males, 11 females, birth weight 1.220 ± 0.293 kg, gestational age 30.96 ± 4.17 weeks) of well-matched non-ROP controls. Metabolites were measured by ultra-performance liquid chromatography-tandem mass spectrometry. Standard multivariate and univariate analysis was performed to interpret metabolomic results. Results Glycine, glutamate, leucine, serine, piperidine, valine, tryptophan, citrulline, malonyl carnitine (C3DC), and homocysteine were identified as the top discriminant metabolites. In particular, discriminant concentrations of C3DC and glycine were also confirmed by univariate analysis as statistically significant different between ROP and non-ROP infants. Conclusions This study gained an insight into the metabolomic aspects of ROP development. We suggest that higher blood levels of C3DC and glycine can be promising biomarkers to predict the occurrence, but not the severity of ROP.

Abstract
PURPOSE To evaluate differences in the progression pattern among subtypes of retinopathy of prematurity (ROP). DESIGN Retrospective cohort study. PARTICIPANTS Premature infants screened for ROP. METHODS Medical records of 578 premature infants who were screened at the neonatal intensive care unit from September 2009 through March 2016 were reviewed. We matched for the number of patients, gestational age at birth, and postmenstrual age at the first examination between infants with spontaneously regressed ROP and those with treated ROP. A total of 133 premature infants who were born before 27 weeks' gestation were included. MAIN OUTCOME MEASURES The mean age at onset of any ROP and the duration from the initial examination to onset were compared between infants with regressed ROP and those with treated ROP. The mean age at treatment and the duration from onset to treatment were compared between infants with type 1 ROP and those with aggressive posterior ROP (AP-ROP). Data were analyzed for 1 randomly selected eye for each infant. RESULTS Of 133 premature infants with any ROP, 67 regressed spontaneously, 43 demonstrated type 1 ROP, and 23 demonstrated AP-ROP. Individual trajectories of ROP progression over time showed that AP-ROP progressed through the stages in a steep linear manner in most cases. In contrast, the type 1 ROP and regressed ROP developed in a slower, stepwise manner. CONCLUSIONS In infants with ROP, the disease trajectories across ROP stages are different based on the ROP subtype, despite postmenstrual age at onset being comparable across subtypes. Our findings could be useful for managing follow-up screening.

Abstract
Importance Most premature infants will not develop retinopathy of prematurity (ROP) of clinical relevance, yet screening evaluations often continue beyond hospital discharge, even for those infants without ROP. Objectives To identify the characteristics of infants at low risk for ROP, for whom further postdischarge screening may be of limited value. Design, Setting, and Participants This study took place in North American neonatal intensive care units where clinicians had expertise in ROP. Infants with birth weight less than 1251 g who were born at or transferred into an Telemedicine Approaches to Evaluating Acute-Phase ROP (e-ROP) study center were enrolled. The study included post hoc analysis of prospectively collected in-hospital ROP examination results among infants enrolled in the e-ROP study. We characterized infants without ROP and performed logistic regression on the subset of infants who were 27 to 33 weeks' gestational age to determine characteristics associated with the absence of ROP during all in-hospital examinations. Main Outcomes and Measures The main measure was the absence of ROP prior to hospital discharge; the main outcome was treatment for ROP. Results A total of 1257 infants born at 22 to 35 weeks' gestation (median [interquartile range (IQR)], 26 [25-28] weeks) with birth weights less than 1251 g (median [IQR], 860 [690-1040] g) underwent 4113 ROP examinations between 31 and 47 weeks' postmenstrual age. Overall, 1153 examinations (38%) showed no ROP, and 456 infants (36%) did not have ROP prior to study center discharge or study end point. Among infants without ROP during examinations at 32 and 33 weeks' postmenstrual age, 16 (9.4%) and 14 (5.3%) subsequently underwent ROP treatment, respectively. At hospital discharge, there was no ROP in 59% of infants of 27 to 33 weeks' gestational age, compared with 15% of those who were less than 27 weeks' gestational age (difference, 44% [95% CI, 38.5%-48.1%]; P ≤ .001). With more than 85% follow-up among infants without ROP by 37 weeks' postmenstrual age, none (95% CI, 0%-0.98%) were treated for ROP. In multivariate analysis of infants born at 27 to 33 weeks' gestation, larger birth weight (OR, 4.1 [95% CI, 1.6-10.3]) and higher gestational age (OR, 4.0 [95% CI, 1.5-10.8]) were significantly associated with absence of ROP. Conclusions and Relevance These findings suggest that, for infants of 27 weeks' gestational age or greater and birth weights larger than 750 g, if no ROP has been detected by discharge at near-term postmenstrual age, then further ROP surveillance has limited value. Studies of all infants at risk are needed to develop more specific, objective criteria for termination of ROP surveillance and focus resources on infants at higher risk of ROP.

Abstract
PURPOSE To assess the frequency of retinopathy of prematurity (ROP) and evaluate the appropriateness of screening guidelines in a tertiary hospital in Thessaloniki, Greece. METHODS Retrospective review of consecutive infants admitted to the IInd Department of the Neonatal Care Unit of Aristotle University in the period April 2004-2015. ROP screening took place according to the Royal College of Paediatrics and Child Health and Royal College of Ophthalmologists (UK) guidelines [i.e. gestational age < 32 weeks and/or birth weight < 1501 g)], plus a few additional cases due to comorbidity. RESULTS 1178 out of the 8782 admitted infants underwent ROP screening. ROP was detected in 232 (19.7%) infants of whom 87 developed severe form of the disease (i.e. ≥ stage 3). Treatment was required in 30 (2.5%) infants, all of whom fulfilled the screening criteria. Two of the 206 infants who were additionally screened due to comorbidity developed severe ROP which regressed spontaneously. Disease regression was achieved in 27/29 (93%) treated infants who survived. CONCLUSIONS The frequency of ROP observed in this cohort was as low as that reported in other developed countries. The currently used screening criteria permitted identification of all infants who were at risk and, therefore, need not be changed.

Abstract
Importance The current guidelines for retinopathy of prematurity (ROP) detection programs in the United States include a range of birth weights (BWs) and gestational ages and likely require examinations of many premature infants who are at low risk for developing serious retinopathy. Objective To determine the incidence, onset, and early course of ROP in what to our knowledge is the largest cohort to date that is representative of infants who are undergoing ROP screening. Design, Setting, and Participants This secondary analysis of data from the Postnatal Growth and Retinopathy of Prematurity (G-ROP) retrospective cohort study was conducted in 29 hospitals in the United States and Canada between January 2006 and December 2011 and included 7483 infants who underwent serial ROP examinations. Main Outcomes and Measures Most severe ROP in either eye, classified as no ROP, mild ROP, type 2 ROP, or type 1 ROP (per Early Treatment for ROP Study criteria). Onset at postmenstrual age for zone I disease and stage of ROP, plus disease, and treatment. Results This study included 7483 infants with a mean (SD) BW of 1099 (259) g and a mean (SD) gestational age of 28 (3) weeks who underwent ROP examinations. Of these, 3224 infants (43.1%) developed ROP, 459 (6.1%) developed type 1 and 472 (6.3%) type 2 ROP, 514 (6.9%) underwent treatment in 1 or both eyes, and 147 (2%) had zone I disease. Additionally, 98.1% of type 1 or 2 ROP cases occurred in infants with a BW of less than 1251 g. Only about half of the eyes (49.4%) were vascularized into zone III by 37 weeks postmenstrual age. Conclusions and Relevance These findings add to our knowledge of ROP screening as they include all eligible infants, not just high-risk infants as in previous studies. More than 40% of at-risk premature infants develop some stage of ROP, and most retinopathy regresses without treatment. However, approximately 12.5% develop severe ROP, which occurs almost exclusively among infants with a BW of less than 1251 g.

Abstract
BACKGROUND AND OBJECTIVES Surgical indications in stages 4B and 5 retinopathy of prematurity (ROP) are not universally accepted. The authors' purpose is to evaluate the long-term anatomic and visual outcomes of vitrectomy for retinal detachment (RD) associated with stages 4B and 5 ROP. PATIENTS AND METHODS Data of patients who consecutively underwent vitrectomy for stages 4B and 5 ROP from 1999 to 2013 were retrospectively reviewed and included grade of retinal attachment and visual acuity (VA) at the last follow-up. RESULTS Seventy eyes of 38 infants were included: 23 with stage 4B and 47 with stage 5 ROP. Lens-sparing vitrectomy was performed in 11 eyes, combined lensectomy / vitrectomy in 59 eyes. Mean follow-up was 8.5 years. Anatomic success was maintained in 41 eyes (58.5%), and among them, VA greater than 5/200 was achieved in 17 eyes (41.4%). CONCLUSION The long-term visual and anatomic success rates were encouraging for the surgical correction of RD associated with late stages ROP.

Abstract
PURPOSE To compare the time course of retinopathy of prematurity (ROP) in premature (≥ 28 to 34 weeks' gestational age) and extremely premature (< 28 weeks' gestational age) infants. METHODS This study was a retrospective single-center chart review that included 582 eyes (122 premature, 464 extremely premature) of 299 infants (65 premature, 234 extremely premature) diagnosed as having ROP who were born between January 1, 2010, and December 31, 2015. Data collected were analyzed with shared frailty models, chi-square, and Fisher's exact tests. RESULTS Extremely premature infants were diagnosed as having ROP earlier than premature infants at 33.6 weeks (95% CI [confidence interval]: 33.4 to 33.9) versus 36.0 weeks (95% CI: 34.7 to 36.4, P < .0001). The time from diagnosis to spontaneous regression was more than 4 weeks longer for extremely premature infants than premature infants with stage 1 ROP (82.0 vs 50.0 days, P < .0001), and more than 6 weeks longer for extremely premature infants than premature infants with stage 2 ROP (99 vs 55 days, P < .0001). Extremely premature infants had more bilateral ROP (96.6% vs 87.1%, P < .01) and were three times more likely to require treatment than premature infants (29.7% vs 9.9%, P < .0001). On average, infants who required treatment weighed 137 grams less at birth (P < .0001) and gained 37.7 grams less per week than infants who underwent spontaneous regression (P < .0001). CONCLUSIONS Extremely premature infants developed ROP earlier, had more bilateral ROP, took longer to achieve spontaneous regression, and required treatment more often than premature infants. Infants who required treatment had a lower birth weight and rate of weight gain than infants who underwent spontaneous regression. [J Pediatr Ophthalmol Strabismus. 2019;56(2):116-123.].

Abstract
PURPOSE Diseases that involve retinal or choroidal vascular endothelial cells are leading causes of vision loss: age-related macular degeneration, retinal ischemic vasculopathies, and noninfectious posterior uveitis. Proteins differentially expressed by these endothelial cell populations are potential drug targets. We used deep proteomic profiling to define the molecular phenotype of human retinal and choroidal endothelial cells at the protein level. METHODS Retinal and choroidal vascular endothelial cells were separately isolated from 5 human eye pairs by selection on CD31. Total protein was extracted and digested, and peptide fractions were analyzed by reverse-phase liquid chromatography tandem mass spectrometry. Peptide sequences were assigned to fragment ion spectra, and proteins were inferred from openly accessible protein databases. Protein abundance was determined by spectral counting. Publicly available software packages were used to identify proteins that were differentially expressed between human retinal and choroidal endothelial cells, and to classify proteins that were highly abundant in each endothelial cell population. RESULTS Human retinal and/or choroidal vascular endothelial cells expressed 5042 nonredundant proteins. Setting the differential expression false discovery rate at 0.05, 498 proteins of 3454 quantifiable proteins (14.4%) with minimum mean spectral counts of 2.5 were differentially abundant in the 2 cell populations. Retinal and choroidal endothelial cells were enriched in angiogenic proteins, and retinal endothelial cells were also enriched in immunologic proteins. CONCLUSIONS This work describes the different protein expression profiles of human retinal and choroidal vascular endothelial cells, and provides multiple candidates for further study as novel treatments or drug targets for posterior eye diseases.

Abstract
With the increasing survival of preterm babies in the Asia-Pacific region, there has been an increase in the incidence of retinopathy of prematurity (ROP). There is also a lack of trained ophthalmologists to screen for this disease. New strategies for screening of ROP are required, wherein the load on the ophthalmologist can be reduced. Telemedicine is an excellent tool to address this need. This paper reviews the initial studies comparing digital imaging with indirect ophthalmoscopy, the current active ROP telescreening programs in the world, and ends with studies dealing with automated diagnosis of ROP.

Abstract
Purpose To assess the association between systemic levels of inflammation-associated proteins and severe retinopathy of prematurity (ROP) in extremely preterm infants. Methods We collected whole blood on filter paper on postnatal days 1, 7, 14, 21, and 28 from 1205 infants born before the 28th week of gestation, and measured the concentrations of 27 inflammation-associated, angiogenic, and neurotrophic proteins. We calculated odds ratios with 95% confidence intervals for the association between top quartile concentrations of each protein and prethreshold ROP. Results During the first three weeks after birth, high concentrations of VEGF-R1, myeloperoxidase (MPO), IL-8, intercellular adhesion molecule (ICAM)-1, matrix metalloproteinase 9, erythropoietin, TNF-α, and basic fibroblast growth factor were associated with an increased risk for prethreshold ROP. On day 28, high levels of serum amyloid A, MPO, IL-6, TNF-α, TNF-R1/-R2, IL-8, and ICAM-1 were associated with an increased risk. Top quartile concentrations of the proinflammatory cytokines TNF-α and IL-6 were associated with increased risks of ROP when levels of neuroprotective proteins and growth factors, including BDNF, insulin-like growth factor 1, IGFBP-1, VEGFR-1 and -2, ANG-1 and PlGF, were not in the top quartile. In contrast, high concentrations of NT-4 and BDNF appeared protective only in infants without elevated inflammatory mediators. Conclusions Systemic inflammation during the first postnatal month was associated with an increased risk of prethreshold ROP. Elevated concentrations of growth factors, angiogenic proteins, and neurotrophins appeared to modulate this risk, and were capable of reducing the risk even in the absence of systemic inflammation.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) still represents one of the leading causes of visual impairment in childhood. Systemic propranolol has proven to be effective in reducing ROP progression in preterm newborns, although safety was not sufficiently guaranteed. On the contrary, topical treatment with propranolol eye micro-drops at a concentration of 0.1% had an optimal safety profile in preterm newborns with ROP, but was not sufficiently effective in reducing the disease progression if administered at an advanced stage (during stage 2). The aim of the present protocol is to evaluate the safety and efficacy of propranolol 0.2% eye micro-drops in preterm newborns at a more precocious stage of ROP (stage 1). METHODS A multicenter, open-label, phase II, clinical trial, planned according to the Simon optimal two-stage design, will be performed to analyze the safety and efficacy of propranolol 0.2% eye micro-drops in preterm newborns with stage 1 ROP. Preterm newborns with a gestational age of 23-32 weeks, with a stage 1 ROP will receive propranolol 0.2% eye micro-drops treatment until retinal vascularization has been completed, but for no longer than 90 days. Hemodynamic and respiratory parameters will be continuously monitored. Blood samplings checking metabolic, renal and liver functions, as well as electrocardiogram and echocardiogram, will be periodically performed to investigate treatment safety. Additionally, propranolol plasma levels will be measured at the steady state, on the 10th day of treatment. To assess the efficacy of topical treatment, the ROP progression from stage 1 ROP to stage 2 or 3 with plus will be evaluated by serial ophthalmologic examinations. DISCUSSION Propranolol eye micro-drops could represent an ideal strategy in counteracting ROP, because it is definitely safer than oral administration, inexpensive and an easily affordable treatment. Establishing the optimal dosage and treatment schedule is to date a crucial issue. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT02504944, registered on July 19, 2015, updated July 12, 2016.

Abstract
The understanding, diagnosis, and treatment of retinopathy of prematurity have changed in the 70 years since the original description of retrolental fibroplasia associated with high oxygenation. It is now recognized that retinopathy of prematurity differs in appearance worldwide and as ever smaller and younger premature infants survive. New methods are being evaluated to image the retina, diagnose severe retinopathy of prematurity, and determine windows of time for treatment to save eyes and improve visual and neural outcomes. New treatments to promote physiologic retinal vascular development, vascular repair, and inhibit vasoproliferation by regulating proteins involved in vascular endothelial growth factor, insulin-like growth factor, or erythropoietin signaling. Reducing excessive oxidative/nitrosative stress and understanding progenitor cells and neurovascular and glial vascular interactions are being studied.

Abstract
PURPOSE OF REVIEW Currently, severe retinopathy of prematurity (ROP) is diagnosed by clinical evaluation and not a laboratory test. Laser is still considered standard care. However, anti-vascular endothelial growth factor (VEGF) agents are being used and there are questions whether and/or if to use them, what dose or type of agent should be considered and what agent may be most beneficial in specific cases. Also unclear are the effects of laser or anti-VEGF on severe ROP, refractive outcomes or infant development. This article reviews recent studies related to these questions and other trials for severe ROP. RECENT FINDINGS Imaging studies identify biomarkers of risk (plus disease, stage 3 ROP, and ROP in zone I). Intravitreal bevacizumab or ranibizumab are reported effective in treating aggressive posterior ROP in small series. Recurrences and effects on myopia vary among studies. Use of anti-VEGF agents affects cytokines in the infant blood and reduces systemic VEGF for up to 2 months, raising potential safety concerns. The effects of treatment vary based on infant size and are not comparable. Evidence for most studies is not high. SUMMARY Studies support experimental evidence that inhibiting VEGF reduces stage 3 ROP and peripheral avascular retina. Ongoing large-scale clinical trials may provide clarity for best treatments of severe ROP. Current guidelines hold for screening and treatment for type 1 ROP.

Abstract
Importance The Telemedicine Approaches to Evaluating Acute-Phase Retinopathy of Prematurity (e-ROP) Study telemedicine system of remote fundus image grading and The Children's Hospital of Philadelphia Retinopathy of Prematurity (CHOP-ROP) postnatal weight gain predictive model are 2 approaches for improving ROP screening efficiency. Current screening has low specificity for severe ROP. Objective To describe a tiered approach to ROP screening (TARP) for identifying children who develop severe ROP using telemedicine and a predictive model synergistically. Design, Setting, and Participants This investigation was a post hoc analysis of a cohort in the e-ROP Study (a multicenter prospective telemedicine study) and the Postnatal Growth and Retinopathy of Prematurity (G-ROP) Study (a multicenter retrospective cohort study). The setting was neonatal intensive care units at The Children's Hospital of Philadelphia and the Hospital of the University of Pennsylvania. Participants in the e-ROP Study were premature infants with a birth weight less than 1251 g and a known ROP outcome enrolled between May 25, 2011, and October 31, 2013. The G-ROP Study enrolled all infants undergoing ROP examinations with a known ROP outcome who were born between January 1, 2006, and December 31, 2011. Main Outcomes and Measures The mean outcomes were the sensitivity for type 1 ROP, reductions in infants requiring imaging or examinations, numbers of imaging sessions and examinations, and total clinical encounters (imaging sessions and examinations combined). The following 4 screening approaches were evaluated: ROUTINE (only diagnostic examinations by an ophthalmologist), CHOP-ROP (birth weight and gestational age, with weekly weight gain initiating examinations when the risk cut point is surpassed), e-ROP IMAGING (trained reader grading of type 1 or 2 ROP initiates diagnostic examinations), and TARP (CHOP-ROP alarm initiates imaging, and imaging finding of severe ROP initiates diagnostic examinations). Results A total of 242 infants were included in the study, with a median birth weight of 858 g (range, 690-1035 g). The median gestational age was 27 weeks (range, 25-29 weeks). Fifty-one percent (124 of 242) were female, and 49% (118 of 242) were male. The race/ethnicity was 27.3% (66 of 242) white, 56.2% (136 of 242) black, 2.1% (5 of 242) Native American, 1.7% (4 of 242) Asian, and 12.8% (31 of 242) other. The sensitivity for detecting type 1 ROP (32 infants) was 100% (95% CI, 89.3%-100%) with each approach. With ROUTINE, 242 infants had 877 examinations; with CHOP-ROP, 184 infants had 730 examinations; with e-ROP IMAGING, 242 infants had 532 imaging sessions, and 94 infants had 345 examinations (877 patient encounters); and with TARP, 182 infants had 412 imaging sessions, and 87 infants had 322 examinations (734 patient encounters). Conclusions and Relevance The tiered approach to ROP screening was associated with a reduced number of examinations and imaging sessions compared with the other approaches. Applying a postnatal growth model and telemedicine system in a tiered approach may reduce the number of clinical ROP interventions more than either approach alone.

Abstract
Purpose. To convey the need for a revised screening strategy for retinopathy of prematurity (ROP) for extremely low birth weight (ELBW) infants in China. Design. A retrospective longitudinal study. Methods. The medical charts of infants with a birth weight (BW) of less than 1 kg were reviewed. The infants were divided into three groups: group A, without ROP; group B, with ROP but not up to type 1 prethreshold or threshold ROP; group C, with type 1 prethreshold or threshold ROP. Data collected included gender, gestational age (GA), BW, postmenstrual age (PMA), age of onset of ROP, and age at which treatment was carried out, if required. Results. A total of 77 infants were involved. Fifty-six infants developed ROP at any stage and 38 infants developed type 1 prethreshold or threshold ROP. The mean BW and GA of infants in group A were significantly different compared with groups B and C. The mean PMA of onset of ROP in infants who developed mild ROP was 37 weeks compared with 34 weeks for infants who developed severe ROP. Conclusion. ELBW infants have a higher incidence of ROP in China which highlights the need for optimizing neonatal care for these infants. In ELBW infants, ROP tends to develop more severely when it occurs earlier. It is necessary for ELBW infants, especially for those with a BW less than 800 g or a GA less than 25 weeks, to be initially screened at an earlier time.
