Abstract
PURPOSE Children born preterm are believed to be at increased risk of visual impairment (VI). The increased survival rate of extremely preterm children may have changed the spectrum of diseases occurring postnatally. The aim of this study was to analyse the prevalence and causes of VI in an ex-preterm Danish population during the last 4 decades. METHODS The study was based on the National Register of Blind and Visually Impaired Children (NRVIC). Ex-preterms born at gestational age (GA) <32 weeks and enrolled in NRVIC at any time between 1988 and 2020 were included. The main cause of VI, the severity of VI and systemic comorbidities were analysed for temporal changes. RESULTS A total of 335 patients were included. The prevalence of VI decreased from 26/1000 preterm children in the 1980s to 15/1000 in 2000s. Blindness due to preterm birth is almost eliminated affecting 1/1000 today. Sequelae to retinopathy of prematurity (ROP) was the most common cause of VI (51% of cases) in the 1980s but decreased to 34% in 2010s, whereas non-ocular causes of VI increased from 1% to 36%, respectively. More than half of the children (64%) had combined comorbidities and 36% had isolated VI. CONCLUSION The improved monitoring in neonatal intensive care units and management of ROP has reduced the prevalence of severe VI due to ROP and almost eliminated blindness over the last decades in Denmark. However, preterm children are still at risk of non-ocular causes of VI and comorbidities following the premature delivery.

Association between severe retinopathy of prematurity (ROP) and poor motor neurodevelopmental outcome. Indian J Ophthalmol 2023; 71:2944-2946. [PMID: 37530261 PMCID: PMC10538842 DOI: 10.4103/ijo.ijo_116_23] [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: 01/12/2023] [Revised: 05/15/2023] [Accepted: 05/21/2023] [Indexed: 08/03/2023] Open
Abstract
During the final (third) trimester outside of the womb, the retina develops significantly and is vulnerable to problems. Similar to how the cerebral cortex does, the cerebellum also grows quickly during this time and is susceptible to upsetting environmental influences. The only factors that show promise for lowering the incidence and retinopathy of prematurity (ROP) severity among high-risk infants are prematurity prevention, preeclampsia control, and prudent use of oxygen therapy and ventilation. The third trimester is when the cerebral cortex, cerebellum, and retina develop. These areas are vulnerable to environmental influences if their development is interrupted. Throughout childhood and adolescence, neurodevelopmental defects have been linked to impaired cortical development and smaller brain volumes. Reduced cerebellar volumes have been linked to an increased risk of autism spectrum disorder, lower motor performance, impaired executive functioning, and poorer cognitive outcomes. The complete avascular retina, as well as the peripheral retina, should be treated during retinal ablation with laser photocoagulation (using a transpupillary diode, 11 argon, and three FD-YAG) or cryoablation as failing to do so promotes disease progression and results in unfavorable anatomical and refractive outcomes.

Abstract
AIM To investigate visual function and neurodevelopment in a geographically defined population cohort of school-aged children born extremely preterm. METHODS All children born extremely preterm in Central Norway between 2006 and 2011 (n=65) were identified, and 36 (median age, min/max: 13, 10/16) were included. Best-corrected visual acuity (BCVA), contrast sensitivity (four spatial frequencies), parent-reported challenges and neuropsychological testing in learning, executive functions, motor skills, perception, reaction time, working and visual memory, processing speed, and pattern separation were measured. Brain MRI (3T) was acquired and read by a neuroradiologist. RESULTS Median (min/max) BCVA letter score was 85 (35/91) in the better and 82 (13/89) in the worse eye. ROP participants (n=7) had lower contrast sensitivity in the two highest spatial frequencies (p = 0.024 and p = 0.004). Parent-reported challenges correlated negatively with BCVA (learning: p = 0.014; executive functions: p = 0.002; motor skills: p = 0.000; and perception: p = 0.001), while motor skills correlated negatively with one (p = 0.010) and perception with two (p = 0.003 and p = 0.009) of four spatial frequencies. Neuropsychological tests were reduced relative to norms. None had MRI-verified preterm brain injury. CONCLUSION Visual function was subnormal and correlated with parent-reported challenges in a small cohort of extremely preterm school-aged children, indicating that visual function may be a marker of neurodevelopmental outcomes.

Retinopathy of prematurity and neurodevelopmental outcomes in preterm infants: A systematic review and meta-analysis. Front Pediatr 2023; 11:1055813. [PMID: 37009271 PMCID: PMC10050340 DOI: 10.3389/fped.2023.1055813] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 01/16/2023] [Indexed: 04/04/2023] Open
Abstract
Background Retinopathy of prematurity (ROP) and abnormal brain development share similar risk factors and mechanisms. There has been contrasting evidence on the association of ROP with adverse neurodevelopmental outcomes. Objective We analysed the association between ROP at levels of severity and treatment with all neurodevelopmental outcomes until adolescence. Data source We followed PRISMA guidelines and searched Medline and Embase between 1 August 1990 and 31 March 2022. Study selection and participants Randomised or quasi-randomised clinical trials and observational studies on preterm infants (<37 weeks) with ROP [type 1 or severe ROP, type 2 or milder ROP, laser or anti-vascular endothelial growth factor (VEGF) treated] were included. Data extraction and synthesis We included studies on ROP and any neurocognitive or neuropsychiatric outcomes. Outcomes The primary outcomes were as follows: cognitive composite scores evaluated between the ages of 18 and 48 months by the Bayley Scales of Infant and Toddler Development (BSID) or equivalent; neurodevelopmental impairment (NDI; moderate to severe NDI or severe NDI), cerebral palsy, cognitive impairment; and neuropsychiatric or behavioural problems. The secondary outcomes were as follows: motor and language composite scores evaluated between the ages of 18 and 48 months by BSID or equivalent; motor/language impairment; and moderate/severe NDI as defined by the authors. Results In preterm infants, "any ROP" was associated with an increased risk of cognitive impairment or intellectual disability [n = 83,506; odds ratio (OR): 2.56; 95% CI: 1.40-4.69; p = 0.002], cerebral palsy (n = 3,706; OR: 2.26; 95% CI: 1.72-2.96; p < 0.001), behavioural problems (n = 81,439; OR: 2.45; 95% CI: 1.03-5.83; p = 0.04), or NDI as defined by authors (n = 1,930; OR: 3.83; 95% CI: 1.61-9.12; p = 0.002). Type 1 or severe ROP increased the risk of cerebral palsy (OR: 2.19; 95% CI: 1.23-3.88; p = 0.07), cognitive impairment or intellectual disability (n = 5,167; OR: 3.56; 95% CI: 2.6-4.86; p < 0.001), and behavioural problems (n = 5,500; OR: 2.76; 95% CI: 2.11-3.60; p < 0.001) more than type 2 ROP at 18-24 months. Infants treated with anti-VEGF had higher odds of moderate cognitive impairment than the laser surgery group if adjusted data (gestational age, sex severe intraventricular haemorrhage, bronchopulmonary dysplasia, sepsis, surgical necrotising enterocolitis, and maternal education) were analysed [adjusted OR (aOR): 1.93; 95% CI: 1.23-3.03; p = 0.04], but not for cerebral palsy (aOR: 1.29; 95% CI: 0.65-2.56; p = 0.45). All outcomes were adjudged with a "very low" certainty of evidence. Conclusion and relevance Infants with "any ROP" had higher risks of cognitive impairment or intellectual disability, cerebral palsy, and behavioural problems. Anti-VEGF treatment increased the risk of moderate cognitive impairment. These results support the association of ROP and anti-VEGF treatment with adverse neurodevelopmental outcomes.

Abstract
OBJECTIVES To retrospectively evaluate ophthalmological and neurological outcomes in a Swedish cohort of infants born before 24 weeks gestational age (GA) and explore risk factors for visual impairment. SETTING Eye and paediatric clinics in Sweden. PARTICIPANTS Infants screened for retinopathy of prematurity (ROP) (n=399), born before 24 weeks GA, 2007-2018. Cases were excluded if ophthalmological follow-up records could not be traced. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcomes were ophthalmological, including visual acuity (VA), refractive error, strabismus, nystagmus and cerebral visual impairment (CVI). Secondary outcomes comprised neonatal and neurological morbidities. Data were retrospectively retrieved from medical records. RESULTS The 355 assessed children had a median GA of 23 weeks and 2 days and a median birth weight of 565 g. At the last available ophthalmological examination, the median age was 4.8 years (range 0.5-13.2 years). Nystagmus was recorded in 21.1%, strabismus in 34.8%, and 51.0% wore spectacles. Seventy-three of 333 (21.9%) were visually impaired, defined as being referred to a low vision clinic and/or having a VA less than 20/60 at 3.5 years of age or older. ROP treatment was a significant risk factor for visual impairment (OR 2.244, p=0.003). Visually impaired children, compared with children without visual impairment, more often had neurological deficits such as intellectual disability 63.8% versus 33.3% (p<0.001), epilepsy 21.1% versus 7.5% (p=0.001) and autism spectrum disorders 32.8% versus 20.9% (p=0.043). Nine of the 355 children had been diagnosed with CVI. CONCLUSIONS Children born before 24 weeks GA frequently had visual impairment in association with neurological deficits. CVI was rarely diagnosed. A multidisciplinary approach for the evaluation and habilitation of these vulnerable infants is warranted. National follow-up guidelines need to be developed and implemented.
