High-resolution retinal imaging in young children using a handheld scanner and Fourier-domain optical coherence tomography.

ABSTRACT:

Purpose

To test the feasibility and applicability of a handheld probe for Fourier-domain optical coherence tomography (Fd-OCT) retinal imaging in infants and children.

Methods

Thirty children ages 7 months to 9.9 years, with (10 of 30) or without (20 of 30) retinal pathology, were imaged with Fd-OCT. Imaging was performed under sedation in 10 of 30 children ages 7 months to 3.7 years. A high-resolution Fd-OCT system (axial resolution: 4.5 mum; acquisition speeds: 1000 A-scans/frame, 9 frames/second), constructed at the UC Davis Medical Center, in conjunction with a handheld scanner, was used for retinal imaging.

Results

Useful images were obtained from all selected patients. Image acquisition was possible in a conscious state in children as young as 3 years of age. Al
