Abstract
Little is known about the structural changes of the ciliary muscle with age and how it may contribute to presbyopia.
Optical coherence tomography (OCT) has been used to perform ciliary muscle biometry at different age and
accommodative states with low resolution and speed. Dynamic imaging and accurate biometry of the ciliary muscle
requires high-speed, high-resolution and correction of the OCT image distortions. We integrate an existing custom-made
Spectral Domain OCT (SD-OCT) platform working at 840nm for biometry of the human eye with a SD-OCT system
working at 1325nm that enables high-speed and high-resolution transscleral imaging of the ciliary muscle dynamically
during accommodation and we developed an algorithm to provide corrected thickness measurements of the ciliary
muscle.
