Abstract

Purpose:: To test the feasibility and applicability of a hand-held scanner for acquiring retinal images with Fourier-domain OCT (Fd-OCT) in infants and children.

Methods:: A high-resolution Fd-OCT system (axial resolution: 4.5µm, acquisition speeds: 10,000 A-scans/frame, 9 frames/second) constructed at the UC Davis Medical Center combined with a hand-held scanner (Bioptigen, Inc) was used for retinal layer image acquisition. Fd-OCT was performed with patients and controls 10 years and younger in an awake state or under sedation. Feasibility was assessed in terms of (1) the ability to acquire B-scans and (2) image quality.

Results:: Data were collected from 30 children, ages 6 months to 10 years. 10 patients were imaged under sedation. Image acquisition was possible in an awake state in children as young as 3 years of age. All children tolerated the tests well. Image quality was comparable to scans obtained with the same instrument in an adult population. High refractive errors due to aphakia or high myopia were limiting factors in scan acquisition.

Conclusions:: The flexible hand-held scanner in association with high resolution Fd-OCT permits retinal image acquisition in infants and children.
