Abstract

We developed a handheld, non-mydriatic swept-source OCT system capable of ultra-widefield and high-resolution retinal imaging across both pediatric and adult patients without pharmacologic dilation. The proposed system employed a 400kHz VCSEL light source with an extended axial imaging range of 12mm in air and achieved a 140° visual angle with custom optics, enabling rapid, panretinal visualization with minimal beam wandering while maintaining diffraction-limited resolution across the field of view.
