Understanding Retinopathy of Prematurity: A Growing Concern for Preterm Infants Worldwide

Retinopathy of Prematurity (ROP), a potentially blinding condition affecting the retinas of premature infants, arises from abnormal blood vessel growth in the retina. Preterm babies, born before 37 weeks of gestation, particularly those under 32 weeks gestational age (GA) or with birth weights below 1,501 grams, face the highest risk. The retina, the light-sensitive layer at the back of the eye responsible for vision, requires precise vascular development during the last trimester of pregnancy. Disruption due to prematurity triggers two phases: initial suppression of normal vessel growth followed by uncontrolled proliferation, potentially leading to retinal detachment and permanent vision loss.

Globally, ROP contributes significantly to childhood blindness, with incidence varying by neonatal care level. In high-resource settings, improved survival of extremely preterm infants has paradoxically increased ROP cases, as lower gestational ages heighten vulnerability. Risk factors include supplemental oxygen therapy, sepsis, intraventricular hemorrhage, and poor postnatal weight gain. In the United Arab Emirates (UAE), advanced neonatal intensive care units (NICUs) have boosted preterm survival, elevating the need for vigilant ROP management.

The Emirates Society of Ophthalmology's Landmark ROP Consensus Statement

The Emirates Society of Ophthalmology (ESO) has unveiled a pivotal consensus statement on ROP management tailored to UAE preterm infants, marking a unified approach to screening, diagnosis, and treatment. This document, published in Cureus, stems from a panel of 10 UAE-based experts using the Nominal Group Technique (NGT) for evidence-based recommendations. Aligned with international standards like the International Classification of Retinopathy of Prematurity (ICROP), it addresses local epidemiology and healthcare infrastructure.

ESO, under leaders like President Sheikha Dr. Noura Al Qassimi and Vice President Dr. Khaled Abuhaleeqa, convened ophthalmologists, neonatologists, and pediatric specialists. Many panelists hold academic positions at institutions such as UAE University College of Medicine and Health Sciences, underscoring the role of higher education in shaping clinical guidelines. This consensus fills a critical gap, standardizing practices across UAE emirates.Read the full consensus

ROP Incidence and Risk Factors Specific to the UAE Context

In the UAE, preterm birth rates hover around 6-7%, with Abu Dhabi reporting 6.3% in recent studies. Among preterm infants, ROP incidence reaches approximately 27%, higher than some regional peers due to NICU advancements saving tinier babies. Local cohorts from Dubai's Latifa and Dubai Hospitals show 26.5% ROP development, with 6.9% requiring treatment.

Risk factors mirror global patterns but with UAE nuances: prolonged oxygen use, multiple pregnancies (e.g., twins/triplets common in fertility treatments), and neonatal infections. Emirati demographics, including consanguinity, may influence severity. Hospitals like Sheikh Khalifa Medical City and Corniche Hospital for Women and Children report treatable ROP in zone I/II stage 2+ or type 1 cases.

Streamlined Screening Protocols Under the New Guidelines

The ESO consensus recommends screening all infants born at <32 weeks GA or <1,501g birth weight, aligning with practices at Moorfields Eye Hospital Dubai and King's College Hospital. First exam timing: 4-7 weeks chronologically for <28 weeks GA, or 4-5 weeks for 28-30 weeks. Subsequent exams every 1-2 weeks based on vascular maturity.

• Infants <1,000g or <28 weeks: screen regardless of stability.
• Binocular indirect ophthalmoscopy (BIO) by trained pediatric ophthalmologists using 25-28D lenses.
• Digital wide-field imaging as adjunct for telemedicine in remote emirates.

This protocol aims to detect pre-threshold ROP early, preventing progression.

Diagnostic Classification and Staging in Practice

Diagnosis follows ICROP: zones (I closest to optic disc, III periphery), stages (1-5 demarcation to total detachment), plus disease (vascular dilation/tortuosity). Type 1 ROP (zone I any +/stage 3, zone II stage 2+ no) mandates urgent treatment. ESO emphasizes standardized documentation via ETROP charts for multidisciplinary communication.

In UAE settings, challenges include inter-observer variability, addressed by ESO-mandated training workshops.

Treatment Thresholds: Laser, Anti-VEGF, and Surgical Interventions

Treatment thresholds mirror ETROP: laser photocoagulation for type 1 ROP, peripheral retinal ablation sealing avascular areas. Anti-VEGF injections (bevacizumab preferred) for zone I pre-threshold or posterior disease, given faster recovery but recurrence risk (20-30%). Surgery (vitrectomy/lens-sparing) for stage 4/5.

• Laser: Gold standard, 80-90% favorable outcomes.
• Anti-VEGF: Off-label but ESO-endorsed with informed consent, monitoring recurrence.
• Multimodal: Combine for severe cases.

UAE centers like DRHC Dubai report success with intravitreal bevacizumab, reducing myopia risk vs. laser.

Follow-Up Care and Long-Term Outcomes

Post-treatment exams every 1-2 weeks until full retinal vascularization or regression. Long-term: annual checks for myopia, strabismus, amblyopia into school age. ESO stresses parental education on visual development milestones.Moorfields ROP follow-up

Outcomes in UAE: >90% vision preservation with timely intervention, but untreated severe ROP leads to 50% blindness risk.

Multidisciplinary Collaboration and Healthcare Infrastructure in UAE

ESO advocates ROP committees in each NICU, involving neonatologists, nurses, ophthalmologists. Partnerships like Danat Al Emarat-Moorfields exemplify integrated care. Ministry of Health and Prevention (MoHAP) supports nationwide implementation.

For medical professionals training in this field, opportunities abound in clinical research jobs focusing on neonatal ophthalmology across UAE universities.

Implications for Medical Education and Research in UAE Higher Education

This consensus elevates pediatric ophthalmology training in UAE medical schools like Mohammed Bin Rashid University and Gulf Medical University. Residency programs now incorporate ROP simulation, aligning with ESO workshops. Researchers can leverage this for studies on genetic factors in Arab populations or AI-assisted screening.Academic career advice for aspiring specialists is available to navigate these evolving standards.

Challenges, Innovations, and Future Outlook

Challenges: workforce shortages, remote access in less urban emirates. Innovations: AI grading tools, remote digital imaging. Future: national ROP registry, prophylactic omega-3 trials. ESO aims for zero preventable blindness by 2030.

Stakeholders praise the guidelines for practicality, with neonatologists noting easier referrals.
