Panretinal handheld OCT angiography for pediatric retinal imaging

Area of Science:

• Pediatric Ophthalmology
• Medical Imaging
• Retinal Disease Diagnosis

Background:

• Comprehensive visualization of pediatric retina morphology is crucial for diagnosing and managing retinal diseases.
• Conventional imaging techniques struggle to capture the peripheral retina effectively due to limited field of view.
• Existing optical designs lack the necessary field of view for characterizing the far periphery in pediatric patients.

Purpose of the Study:

• To introduce and evaluate a novel ultra-widefield optical coherence tomography angiography (OCTA) system for pediatric applications.
• To address the limitations of conventional imaging in capturing the peripheral retina.
• To enhance the diagnosis and management of retinal diseases in pediatric populations.

Main Methods:

• Development of a novel ultra-widefield OCTA system with an ultrahigh-speed 800 kHz swept-source laser.
• The system achieves a 140° field of view with excellent optical performance.
• Conducted 379 eye examinations on 96 babies over 15 months.

Main Results:

• The ultra-widefield OCTA system demonstrated marked efficacy in diagnosing retinopathy of prematurity.
• Provided detailed and comprehensive peripheral retinal angiography.
• Significantly improved the clarity and thoroughness of retina vascularization assessments.

Conclusions:

• The novel ultra-widefield handheld OCTA system enhances diagnostic precision and treatment customization in pediatric ophthalmology.
• The system has the potential to broaden the scope of retinal imaging in pediatric care.
• Findings underscore the system's advancement in pediatric retinal disease management.
