Abstract
Purpose We aimed to identify the risk factors that may predispose preterm neonates to develop aggressive posterior retinopathy of prematurity (APROP). Methods This retrospective case control study included 16 infants with APROP in zone 1 or posterior zone 2. Thirty-four gestational age and birth weight-matched controls with stage 2 or less ROP were included. We reviewed medical records on infant birth and postnatal characteristics. Results Patients who developed APROP had a significantly longer duration of caffeine therapy, were significantly more likely to be small for gestational age (SGA), and were more likely to have a positive blood culture than patients who developed less severe ROP. Patients with APROP who required retreatment had received inotropes for a longer duration of time, had received more plasma transfusions, were more likely to have IVH, and had a greater decrease in the serum hemoglobin during hospitalization. Conclusion Being SGA, receiving caffeine for a longer duration, and having culture-proven sepsis were associated with APROP. IVH, a low serum hemoglobin, the need for more plasma transfusions, and a longer duration of inotropes were associated with APROP which required retreatment.

Abstract
PURPOSE To evaluate differences in autonomic nervous system (ANS) activity associated with the development of retinopathy of prematurity. METHODS Heart rate variability (HRV) as an indicator of ANS activity was calculated in two groups of premature infants: (1) a treatment group of infants who developed type 1 ROP and underwent treatment and (2) a control group of infants who did not develop ROP more severe than stage 1 and who were matched to the treatment group in terms of age, weight, and similar risk factors, including similar frequency of intraventricular hemorrhage, bronchopulmonary dysplasia, and sepsis. HRV was analyzed during the first 5 days of life, within 5 days of initial ROP examination, and within 5 days of ROP treatment for the treatment group or, for controls, on the day of last electrocardiogram data prior to discharge. Calculations were performed for the high frequency, low frequency, and low frequency-high frequency values of the HRV components for all infants. RESULTS Between the initial ophthalmologic evaluation and the final evaluation, there was a tendency for reduction in both the low- and high-frequency components of the HRV indices in the treatment group, whereas there was a tendency for an increase in both components of the HRV indices in the control group. The difference in the rate of change of the high frequency between groups was statistically significant (P = 0.021). CONCLUSIONS Disruption in ANS activity may play an important role in the development and severity of ROP.

Abstract
Retinopathy of prematurity (ROP) is a retinal vasoproliferative disease that affects premature infants. Despite improvements in neonatal care and management guidelines, ROP remains a leading cause of childhood blindness worldwide. Current screening guidelines are primarily based on two risk factors: birth weight and gestational age; however, many investigators have suggested other risk factors, including maternal factors, prenatal and perinatal factors, demographics, medical interventions, comorbidities of prematurity, nutrition, and genetic factors. We review the existing literature addressing various possible ROP risk factors. Although there have been contradictory reports, and the risk may vary between different populations, understanding ROP risk factors is essential to develop predictive models, to gain insights into pathophysiology of retinal vascular diseases and diseases of prematurity, and to determine future directions in management of and research in ROP.

N-terminal B-type natriuretic peptide urinary concentrations and retinopathy of prematurity. Pediatr Res 2017; 82:958-963.

Abstract
BackgroundTo validate the findings of a single-center pilot study showing elevated urinary N-terminal B-type natriuretic peptide (NTproBNP) concentrations in preterm infants subsequently developing severe retinopathy of prematurity (ROP) in a multicenter setting across eight European and Middle East countries.MethodsProspective observational study in 967 preterm infants <30 weeks' gestational age assessing the capacity of urinary NTproBNP on days of life (DOLs) 14 and 28 to predict ROP requiring treatment.ResultsUrinary NTproBNP concentrations were markedly elevated in infants who developed ROP requiring treatment (n=94) compared with survivors without ROP treatment (n=837), at both time points (median (interquartile range) DOL14: 8,950 (1,925-23,783) vs. 3,083 (1,193-17,393) vs. 816 (290-3,078) pg/ml, P<0.001) and DOL28 (2,203 (611-4,063) vs. 1,671 (254-11,340) vs. 408 (162-1,126) pg/ml, P<0.001). C-statistic of NTproBNP for treated ROP or death was 0.731 (95% confidence interval 0.654-0.774) for DOL14 and 0.683 (0.622-0.745) for DOL28 (P<0.001). Threshold scores were calculated, potentially enabling around 20% of infants with low NTproBNP scores never to be screened with ophthalmoscopy.ConclusionThere is a strong association between early urinary NTproBNP and subsequent ROP development, which can be used to further refine subgroups of patients with high or low risk of severe ROP.

Evaluating the association of autonomic drug use to the development and severity of retinopathy of prematurity. J AAPOS 2014; 18:332-7. [PMID: 25173894 DOI: 10.1016/j.jaapos.2014.02.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2013] [Revised: 02/10/2014] [Accepted: 02/14/2014] [Indexed: 11/20/2022]
Abstract
PURPOSE To explore the association of autonomic agents with the development and severity of retinopathy of prematurity (ROP). METHODS The medical records of all preterm infants screened for ROP were retrospective reviewed. The association between development and severity of ROP and the use and dose(s) of autonomic agents was analyzed, after adjustment for the covariates gestational age, weight, development of septicemia, intraventricular hemorrhage, and respiratory distress syndrome. RESULTS A total of 350 infants were screened. Caffeine was used in 338 infants; dopamine in 98 infants. There was a significant association between the use of dopamine and development of ROP (P < 0.001; relative risk [RR] = 1.6 [95% CI, 1.23-2.06]) and the need for ROP treatment (P = 0.001; RR = 4.63 [95% CI, 1.82-11.79]). The number of dopamine doses was significantly associated with the development of any ROP (P < 0.001; RR = 1.07 [95% CI, 1.03-1.1]), the severity of ROP (P < 0.001; RR = 1.09 [95% CI, 1.05-1.14]), and the need for treatment (P < 0.001; RR = 1.09 [95% CI, 1.05-1.14]). The total dose of caffeine was significantly associated with the development of any ROP (P = 0.003; RR = 1.03 [95% CI, 1.01-1.05]) and the need for treatment (P = 0.006, RR = 1.073 [95% CI; 1.021-1.13]). CONCLUSIONS Although a causal relationship was not identified, the use of the autonomic agents caffeine and dopamine was associated with the development and severity of retinopathy of prematurity in this cohort.
