Prevention of retinopathy of prematurity

Area of Science:

• Ophthalmology
• Neonatology
• Vascular Biology

Background:

• Retinopathy of prematurity (ROP) is a leading cause of preventable blindness in preterm infants.
• ROP pathogenesis involves oxygen-regulated growth factors (VEGF, IGF-I) and abnormal retinal vascular development.
• Increased preterm infant survival rates correlate with a rising global prevalence of ROP, particularly in developing regions.

Purpose of the Study:

• To outline the primary preventive measures for retinopathy of prematurity.
• To highlight the importance of early diagnosis and intervention in managing ROP.
• To discuss the impact of supplemental oxygen on retinal vasculogenesis and ROP onset.

Main Methods:

• Review of existing literature on ROP pathogenesis and prevention.
• Analysis of factors contributing to increased ROP prevalence in preterm infants.
• Synthesis of current recommendations for ROP management.

Main Results:

• Supplemental oxygen can cause retinal hyperoxia, vasoconstriction, and interrupted vasculogenesis.
• Peripheral retinal ischemia is a key factor stimulating neovascularization and ROP complications.
• Prompt diagnosis and management are crucial to prevent irreversible blindness.

Conclusions:

• Effective ROP prevention strategies are essential for safeguarding vision in preterm infants.
• Understanding the role of oxygen and growth factors is key to developing targeted interventions.
• Global collaboration is needed to address the increasing burden of ROP in emerging economies.
