ABSTRACT

BACKGROUND: Preterm infants are at risk of complications due to their prematurity and Retinopathy of Prematurity (ROP) is one of them. To discover and treat ROP the preterm infants regularly undergo eye examinations. Nurses are responsible for the infants' care during this painful and stressful procedure. AIM: The aim of this study was to explore nurses' perceptions of preterm infants' eye examinations. METHODS: Data were collected through semi-structured interviews with 10 nurses experienced in participating in preterm infants' eye examinations. Data were analysed using a phenomenographic approach. RESULTS: The results showed several perceptions of the eye examinations, and the analysis resulted in four descriptive categories: Infants are affected by the eye examination; Nurses have comprehensive overall responsibility for the infants; Parents are important to their infants, but they need support to fulfil their parental role, and Collaboration is important for the examination's favourable outcome. The category Nurses have comprehensive overall responsibility for the infants was regarded as the most comprehensive, covering all the other categories. CONCLUSIONS: Nurses felt a great responsibility during a painful and stressful procedure for preterm infants. Infants' well-being could be better protected by interprofessional collaboration, improved nursing care and involved parents.

ABSTRACT

Purpose: To determine the independent effect of uteroplacental malperfusion on the development of retinopathy of prematurity (ROP). Methods: This cohort study included 591 neonates with a gestational age (GA) ≤ 32 weeks or birthweight (BW) ≤ 1500 g. Clinical data was retrospectively collected and placentas were prospectively examined for maternal vascular malperfusion (e.g., abruption, infarct, distal villous hypoplasia, ischemia, and decidual necrosis) and fetal vascular malperfusion (e.g., thrombosis, fetal hypoxia, and hydrops parenchyma). The primary outcome was ROP. Secondary outcomes were GA, BW, small for gestational age (SGA), mechanical ventilation duration, postnatal corticosteroids, sepsis, and necrotizing enterocolitis. Results: Maternal vascular malperfusion was associated with higher GA, lower BW, and increased SGA rates, except placental abruption, which was associated with lower SGA rates. Fetal vascular malperfusion was associated with lower BW, increased SGA rates and lower duration of mechanical ventilation. Subgroup analysis of placentas without inflammation showed increased rates of distal villous hypoplasia (44% vs. 31%) and hydrops parenchyma (7% vs. 0%) in neonates with ROP. Multivariate regression analyses revealed three placenta factors to be independently associated with ROP: distal villous hypoplasia (OR = 1.7; 95% CI, 1.0-3.0), severe acute histological chorioamnionitis (OR = 2.1; 95% CI, 1.1-3.9) and funisitis (OR = 1.8; 95% CI, 1.0-3.1). Conclusions: Placental evaluation of distal villous hypoplasia, severe acute chorioamnionitis and funisitis is a novel and valuable addition to the ROP risk profile. Evaluation of these placental risk factors shortly after birth can aid in identifying high-risk infants in an earlier stage than currently possible.

ABSTRACT

INTRODUCTION: Early prediction and timely treatment are essential for minimizing the risk of visual loss or blindness of retinopathy of prematurity, emphasizing the importance of ROP screening in clinical routine. OBJECTIVE: To establish predictive models for ROP occurrence based on the risk factors using artificial neural network. METHODS: A cohort of 591 infants was recruited in this retrospective study. The association between ROP and perinatal factors was analyzed by univariate analysis and multivariable logistic regression. We developed predictive models for ROP screening using back propagation neural network, which was further optimized by applying genetic algorithm method. To assess the predictive performance of the models, the areas under the curve, sensitivity, specificity, negative predictive value, positive predictive value and accuracy were used to show the performances of the prediction models. RESULTS: ROP of any stage was found in 193 (32.7%) infants. Twelve risk factors of ROP were selected. Based on these factors, predictive models were built using BP neural network and genetic algorithm-back propagation (GA-BP) neural network. The areas under the curve for prediction models were 0.857, and 0.908 in test, respectively. CONCLUSIONS: We developed predictive models for ROP using artificial neural network. GA-BP neural network exhibited superior predictive ability for ROP when dealing with its non-linear clinical data.

ABSTRACT

BACKGROUND: Retinopathy of prematurity (ROP), is a preventable leading cause of blindness in infants and is a condition in which the immature retina experiences abnormal blood vessel growth. The development of ROP is multifactorial; nevertheless, the risk factors are controversial. This study aimed to identify risk factors of time to development of ROP in Iran. METHODS: This historical cohort study utilized data from the hospital records of all newborns referred to the ROP department of Farabi Hospital (from 2017 to 2021) and the NICU records of infants referred from Mahdieh Hospital to Farabi Hospital. Preterm infants with birth weight (BW) ≤ 2000 g or gestational age (GA) < 34 wk, as well as selected infants with an unstable clinical course, as determined by their pediatricians or neonatologists, with BW > 2000 g or GA ≥ 34 wk. The outcome variable was the time to development of ROP (in weeks). Random survival forest was used to analyze the data. RESULTS: A total of 338 cases, including 676 eyes, were evaluated. The mean GA and BW of the study group were 31.59 ± 2.39 weeks and 1656.72 ± 453.80 g, respectively. According to the criteria of minimal depth and variable importance, the most significant predictors of the time to development of ROP were duration of ventilation, GA, duration of oxygen supplementation, bilirubin levels, duration of antibiotic administration, duration of Total Parenteral Nutrition (TPN), mother age, birth order, number of surfactant administration, and on time screening. The concordance index for predicting survival of the fitted model was 0.878. CONCLUSION: Our findings indicated that the duration of ventilation, GA, duration of oxygen supplementation, bilirubin levels, duration of antibiotic administration, duration of TPN, mother age, birth order, number of surfactant administrations, and on time screening are potential risk factors of prognosis of ROP. The associations between identified risk factors were mostly nonlinear. Therefore, it is recommended to consider the nature of these relationships in managing treatment and designing early interventions.

ABSTRACT

Objectives: To evaluate the characteristics and surgical outcomes of late-onset rhegmatogenous retinal detachment (RRD) associated with regressed retinopathy of prematurity (ROP) and the status of fellow eyes. Materials and Methods: Retrospective review of consecutive cases undergoing surgery for regressed ROP-related RRD and the fellow eyes between 2012-2022. Demographic data, fundus findings, retinal detachment characteristics, surgical procedures, and anatomic and functional outcomes were analyzed. Anatomic success was defined as retinal attachment after silicone oil removal at final follow-up. Results: Fifteen eyes of 14 patients with a history of regressed ROP underwent surgical repair for RRD at a mean age of 12 (range, 3-26) years. Primary surgical intervention yielded a 53% failure rate overall. This rate was 33% for scleral buckling (SB), 100% for pars plana vitrectomy (PPV), and 40% for combined SB-PPV surgery. Eyes with posterior cicatricial changes and/or proliferative vitreoretinopathy (PVR) demonstrated a higher tendency for recurrence. The final anatomic success rate was 73% after a mean number of 2.3 (range, 1-5) surgeries. The chances of restoring useful vision diminished with repeated surgery despite the improvement in anatomic success. In the fellow eyes, peripheral retinal pathologies were universally observed, with posterior cicatricial changes noted in 33%. Conclusion: The study reveals a significant initial failure rate in surgical treatment of cases with late-onset RRD associated with regressed ROP, particularly in eyes with posterior cicatricial changes or PVR, suggesting the need for a combined surgical approach as an initial strategy in such high-risk cases. The consistent presence of retinal abnormalities in fellow eyes calls for proactive monitoring and potential prophylactic intervention.

ABSTRACT

AIM: To evaluate level of agreement of specialist trained retinopathy of prematurity (ROP) nurses compared with an experienced paediatric ophthalmologist in detection of referral-warranted ROP (RWROP) using wide-field digital retinal imaging. METHODS: This is a prospective, observational, blinded study of neonates in a level III neonatal intensive care unit, from July 2020 to November 2022. Image capture using wide-field digital retinal imaging followed by ROP grading and staging was completed by trained ROP nurses. This was then compared with findings by an experienced paediatric ophthalmologist. The primary outcome was presence of RWROP in either eye. RESULTS: One hundred and ninety-five neonates (55% male) with a total of 768 screening visits were included. At the initial screen, nurse and ophthalmologist agreed about presence of RWROP for 191 of 195 neonates (98%, kappa = 0.79, P < 0.0001), with 100% sensitivity for RWROP detection. Including all 768 screening episodes, agreement was 98% for RWROP. There was disagreement in 16 screenings (2%) for 11 (6%) neonates. Of the five screenings (0.7%) that the ophthalmologist thought were RWROP and the nurse did not, three were disagreements about whether the zone was posterior zone 2 or zone 1. CONCLUSIONS: We found excellent levels of agreement and add evidence that interpretations by specialist trained nurses could be safely integrated into a 'hybrid ROP screening system'.

ABSTRACT

OBJECTIVES: This prospective cohort study aimed to investigate the ocular outcomes of universal eye screening in newborns and assess the relationship between different perinatal risk factors and various ocular abnormalities in infants who do not meet the criteria for retinopathy of prematurity (ROP) screening. METHODS: An universal eye screening questionnaire was utilised to screen newborn babies who did not meet the ROP screening criteria within 72 h of birth at a public and private hospital between June 2016 and April 2018. The questionnaire covered demographic characteristics, neonatal history, and eye examination findings. A trained retina specialist conducted comprehensive anterior and posterior segment examinations utilising a binocular indirect ophthalmoscope. RESULTS: Out of the 1795 newborns screened, 55.2% were male, and 44.8% were female. The most prevalent ocular abnormality observed was retinal haemorrhage (RH), with a prevalence of 10.64% (95% CI: 9.25-12.16%). The prevalence of non-RH abnormality was 7.5% (95% CI: 6.34-8.84%). The retinal haemorrhages were associated with normal vaginal deliveries (OR: 9.91; 95% CI: 6.71-14.64, p-value < 0.001), while non-RH abnormalities were associated with pre-term babies (OR: 4.87; 95% CI: 3.03-7.83, p < 0.001), consanguinity (OR: 2.20; 95% CI: 1.28-3.8, p < 0.001), low birth weight (OR: 0.22; 95% CI: 0.14-0.34, p < 0.001) and systemic abnormalities (OR: 3.08; 95% CI: 1.94-4.91, p < 0.001). CONCLUSIONS: Sight-threatening ocular pathology in newborns may be linked to perinatal risk factors such as preterm birth, low birth weight, consanguinity, and systemic abnormalities. Accordingly, it may be prudent to consider specialized ocular screening protocols for neonates within this high-risk cohort in future prospective studies.

ABSTRACT

PURPOSE: To compare the results of intravitreal bevacizumab (IVB) monotherapy and combined intravitreal bevacizumab and laser photocoagulation (LPC) therapies applied in the same session to patients with aggressive retinopathy of prematurity (A-ROP) in our clinic. METHODS: The study included 67 eyes of 37 patients diagnosed with A-ROP and treated. Forty-nine eyes treated with anti-vascular endothelial growth factor agent injection monotherapy for A-ROP treatment were included in the first group. The second group consisted of 18 eyes that received injection therapy and LPC treatment. The clinical findings of the two groups were investigated, and their treatment results were compared. RESULTS: Recurrence was observed in 19 of the 49 (38%) eyes in the first group, but there was no recurrence in any of the cases in the second group. While only IVB was applied to eight cases with recurrence, the combination of LPC and IVB treatment was applied to 11 cases. A second recurrence was detected in two of the eight cases that had received IVB monotherapy as a treatment for recurrence and in three of the 11 cases that had received LPC and IVB. The treatment outcomes of the two groups did not statistically significantly differ (P = 0.181). CONCLUSION: We consider that the combined simultaneous LPC and IVB treatment we applied in A-ROP cases is an effective approach, particularly for cases where there are concerns about the patient's ability to attend follow-up appointments.

ABSTRACT

AIMS: The aims of this research include adapting a patient information tool for whanau (extended family) Maori needs, identifying and reviewing written information provided for the retinopathy of prematurity eye examination (ROPEE) and identifying improvements to ROPEE written information. METHODS: ROPEE patient information (printed leaflets, website, app) was obtained from all tertiary neonatal intensive care units in Aotearoa New Zealand (Aotearoa). Information was reviewed using an adapted "20 good-design principles" guide and given a star rating and Flesch-Kincaid readability score to identify acceptability and usability for patients. RESULTS: Seven ROPEE information materials were reviewed and varied in alignment with the adapted good-design principles tool. Based on the adapted good-design principles, opportunities were identified in many aspects of the written information for improvement, including words and language, tone and meaning, content and design. The Flesch-Kincaid grade level reading scores ranged from 12-22 years reading age. Written information also did not use te reo Maori (Aotearoa Indigenous language) or extensively use Maori imagery. CONCLUSION: Opportunities exist to improve ROPEE whanau information, including making content more readable, understandable and visually appealing. Optimising the clinical information on ROPEE nationally for Aotearoa will support whanau decision making, and aligning written information with Maori (Indigenous peoples of Aotearoa) is a priority.

ABSTRACT

PURPOSE: To provide automatic detection of Type 1 retinopathy of prematurity (ROP), Type 2 ROP, and A-ROP by deep learning-based analysis of fundus images obtained by clinical examination using convolutional neural networks. MATERIAL AND METHODS: A total of 634 fundus images of 317 premature infants born at 23-34 weeks of gestation were evaluated. After image pre-processing, we obtained a rectangular region (ROI). RegNetY002 was used for algorithm training, and stratified 10-fold cross-validation was applied during training to evaluate and standardize our model. The model's performance was reported as accuracy and specificity and described by the receiver operating characteristic (ROC) curve and area under the curve (AUC). RESULTS: The model achieved 0.98 accuracy and 0.98 specificity in detecting Type 2 ROP versus Type 1 ROP and A-ROP. On the other hand, as a result of the analysis of ROI regions, the model achieved 0.90 accuracy and 0.95 specificity in detecting Stage 2 ROP versus Stage 3 ROP and 0.91 accuracy and 0.92 specificity in detecting A-ROP versus Type 1 ROP. The AUC scores were 0.98 for Type 2 ROP versus Type 1 ROP and A-ROP, 0.85 for Stage 2 ROP versus Stage 3 ROP, and 0.91 for A-ROP versus Type 1 ROP. CONCLUSION: Our study demonstrated that ROP classification by DL-based analysis of fundus images can be distinguished with high accuracy and specificity. Integrating DL-based artificial intelligence algorithms into clinical practice may reduce the workload of ophthalmologists in the future and provide support in decision-making in the management of ROP.

ABSTRACT

AIM: To determine the effect of music applied during the ROP examination on pain, comfort, and physiological parameters in preterm infants. METHODS: The sample of this prospective randomized controlled double-blind experimental study consisted of 28 preterm infants who were examined for ROP of a tertiary hospital in the Neonatal Unit. Data were collected with a Questionnaire, Physiological Parameters Observation Form (PPOF), Revised-Premature Infant Pain Profile (PIPP-R), and Premature Infant Comfort Scale (PICS). RESULTS: The results revealed that the crying times of the infants in the experimental group were shorter than the infants in the control group. The preterm infants in the experimental group had statistically lower PIPP-R scores during and after the procedure than the PIPP-R scores of the infants in the control group (p < 0.001) and the music applied to the preterm infants resulted in a mean decrease of 3.857 in the post-procedure and pre-procedure PIPP-R scores (p < 0.05). While there was no statistical difference between the pre-procedure and pre-procedural PICS scores of the preterm infants in the experimental and control groups (p = 0.599; p = 117), the post-procedure PICS values of the preterm infants in the experimental group were found to be lower than those of the control group (p < 0.001). It was found that the music applied to preterm infants during the ROP examination resulted in a mean decrease of 1.286 in PICS scores after the procedure and before the procedure (p < 0.05). CONCLUSION: It was determined that the music listened to during the ROP examination decreased the PIPP-R pain scores of preterm infants, had a positive effect on the PICS scores after the procedure, but did not affect the physiological parameters positively.

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

BACKGROUND: Retinopathy of prematurity (ROP) is a proliferative disorder of the developing retina. Intravitreal bevacizumab injection (IVB) is an emerging treatment for severe forms of ROP, which does not restrict the visual field in comparison to laser therapy. The present study aimed to determine and evaluate the risk factors for ROP recurrence following IVB injection. MATERIALS AND METHODS: In this retrospective study, 98 eyes of 49 infants with ROP who had received IVB injections as the primary treatment for type 1 ROP are included. RESULTS: Fifty-four eyes (55.1%) had aggressive retinopathy of prematurity (A-ROP), and forty-four (44.9%) had Stage III Plus ROP in Zone II. ROP recurred in 13 eyes (13.26%) of 8 infants. The mean period between IVB and the ROP recurrence was 8.08 (95% CI:5.32-10.83) weeks. The infants who had ROP recurrence had lower birth weight (P value = 0.002), lower postmenstrual age at IVB injection (P value = 0.001), lower IVB injection gap period from birth (P value = 0.044), higher oxygen therapy requirement rate after IVB injection (P value < 0.001, OR:19.0) and higher oxygen therapy duration (P value = 0.006). The ROP severity, gestational age at birth, and diet were not statistically different between the recurrence and complete regression groups. Out of 13 eyes treated with laser photocoagulation because of ROP relapse, macula dragging occurred in one eye, and all the cases met the complete regression. CONCLUSION: Low birth weight and oxygen therapy are the most important risk factors for ROP relapse, which requires meticulous oxygen treatment guidelines for premature infants.

ABSTRACT

OBJECTIVE: To assess the morphological state of the visual analyzer in premature infants in long-term. MATERIAL AND METHODS: We examined 40 premature children (74 eyes) aged 10.3±2.92 years (gestational age (GA) 25-34 weeks, birth weight (BW) 690-2700 g). Twenty mature children (40 eyes), aged 10.8±3.05 years, were examined as a control group. The children underwent standard ophthalmologic examination, optical coherence tomography (OCT) and recording of visual evoked potentials (VEP). RESULTS: The thickness of retinal nerve fiber layer (RNFL) is less in preterm infants than in term infants, regardless of retinopathy of prematurity (ROP) and refraction (p<0.05). Thickness loss has an inverse proportion with the degree of hypoxic-ischemic encephalopathy (HIE) and intraventricular hemorrhage (IVH) (p<0.05). Retinal thickness in fovea is significantly greater in preterm infants and has a direct proportionality with the degree of IVH and the number of days on artificial lung ventilation (p<0.05). Moderate organic changes were detected in conduction pathways in 43.08% of premature infants according to VEP data. CONCLUSION: The use of OCT and recording of VEP may improve the quality of comprehensive neuro-ophthalmologic diagnosis in preterm infants. The thickness loss of RNFL can be expected in premature infants with HIE and IVH.

ABSTRACT

PURPOSE: To study the long-term effects of perinatal high-dose recombinant human erythropoietin (rhEPO) on macular structural and vascular development in preterm children. DESIGN: Randomized, double-blind clinical trial follow-up plus cohort study. METHODS: Setting: Department of Ophthalmology, University Hospital Zurich, Zurich, Switzerland. STUDY POPULATION: extremely or very preterm born children aged 7-15 years from an ongoing neuropediatric study (EpoKids). These had been previously randomized to receive either high-dose rhEPO or placebo perinatally. INCLUSION CRITERIA: participation in the EpoKids Study, written informed consent (IC). EXCLUSION CRITERIA: previous ocular trauma or surgery; retinal or developmental disease unrelated to prematurity. Term-born children of comparable age were enrolled as a healthy control (HC) group. INCLUSION CRITERIA: term birth, IC. EXCLUSION CRITERIA: any ocular or visual abnormality, high refractive error. Examiners were blinded regarding intervention status until completion of all analyses. (Participants/guardians remain blinded). OBSERVATION PROCEDURES: Spectral-domain OCT scans (Heidelberg Spectralis system) and OCTA imaging (Zeiss PlexElite 9000) were obtained. Ophthalmological and orthoptic examinations excluded ocular comorbidities. MAIN OUTCOME MEASURES: OCT (central retinal thickness, CRT; total macular volume, TMV), superficial plexus OCTA (foveal avascular zone, FAZ; vessel density, VD; vessel length density, VLD) parameters and foveal hypoplasia grade according to published criteria. RESULTS: Macular vessel density parameters (VD and VLD) were significantly lower (p =0.015, CI-95: 0.01 to 0.06 and p=0.015, CI-95: 0.74 to 3.64) in the EPO group (n= 52) when compared to placebo (n=35). No other significant differences were observed between the EPO and placebo group. When comparing the intervention subgroups to HC we found six significant differences in OCT and OCTA parameters (FAZ, VD, VLD and CRT comparing HC and EPO group; FAZ and CRT when comparing HC and placebo group). CONCLUSIONS: Early high-dose rhEPO in infants born extremely or very preterm affects macular vessel density parameters compared to placebo. Premature birth (regardless of intervention status) affects retinal structure and vascular development. Our findings on macular vascular development do not contraindicate the administration of early high-dose EPO in preterm infants. For further understanding of the role of EPO on macular development and its clinical significance, future studies are needed.

ABSTRACT

PURPOSE: To evaluate the incidence, risk factors, and development of retinopathy of prematurity (ROP) in midpreterm and late-preterm infants born at 32 to 36 6/7 weeks of gestational age. METHODS: The ophthalmic examination findings and risk factors of 5,477 preterm infants who underwent ophthalmological examination were evaluated retrospectively. The rates of any stage and severe ROP (requiring treatment) development and treatment options were recorded. The risk factors were analyzed by using logistic regression analysis. RESULTS: A total of 5,477 infants were included in the study, of whom 2,715 (49.57%) were mid-preterm and 2,762 (50.43%) were late-preterm. The rates of any stage and severe ROP were 8.2% (n = 223) and 0.6% (n = 15) in mid-preterm infants, respectively. In late-preterm infants, the rate of any stage ROP was 2.1% (n = 59), and no severe ROP was detected. There was no significant difference in mean birth weight in mid-preterm infants between infants with any stage ROP and severe ROP (P = .104). Of the 15 infants (0.3%) who required treatment, 14 (0.2%) infants had laser photocoagulation, 1 (0.01%) had intravitreal bevacizumab, and 2 (0.03%) had additional therapy (laser photocoagulation and intravitreal bevacizumab). In logistic regression analysis, a significant association was found between treatment requirement and transport from an external center (P < .001, ß = 0.04). CONCLUSIONS: Although ROP development rates decrease as birth weight and gestational age increase, late-preterm infants should be examined for ROP at least once, especially those born in low-income countries because ROP development can still be observed.

ABSTRACT

PURPOSE: To evaluate the demographic profile of premature infants presenting with stage 4B and stage 5 retinopathy of prematurity (ROP) at a tertiary referral center in South India. METHODS: This was a retrospective review including all premature infants with stage 4B and 5 ROP between January 1, 2015 and December 31, 2022. Parameters included the newborns born at the tertiary care nursery of various institutes, gestational age, birth weight, age at presentation to the hospital, risk factors, screening details, neonatal intensive care unit details, reason for consultation, and timing of referral to the center. RESULTS: Two hundred twenty eyes of 110 premature infants were included. Of 110 infants, 6 were born within the same city and 104 were from other districts or states. Mean birth weight was 1,125 ± 360 g and mean gestational age at birth was 28 ± 2 weeks. Mean age was 42 ± 82 weeks and median age at presentation was 17 weeks (range: 2.86 to 591 weeks). Male-to-female infant ratio was 1.34:1. Fifty (45.4%) infants had bilateral stage 5 ROP, 17 (15.4%) had stage 5 in one eye and stage 4B in the other eye, 15 (13.6%) had bilateral stage 4B and 23 (20.9%) had stage 4B in one eye and stage 4A/stage 3 in the other eye. Five (4.5%) had stage 5 in one eye and vitreous hemorrhage/stage 4A in the other eye. Among those with bilateral stage 5 ROP, 90% were from neighboring districts/states. Fifty-two (47.27%) infants underwent vitreoretinal surgery. Of 110 infants, 28 (25.45%) were self-referred (late presentation due to family-related issues), 80 (72.73%) were referred by ophthalmologists either after a few sessions of late screening or for further management, 1 (0.91%) was referred through telescreening, and 1 was referred from pediatricians directly to the hospital. CONCLUSIONS: This study highlights the importance of awareness of the disease and screening of premature infants. Lack of these two factors leads to late presentation of these infants with advanced stages and serious implications. [J Pediatr Ophthalmol Strabismus. 2024;61(5):339-343.].
