Observing the Morphology of Schlemm's Canal and Crystalline Lens in Different Age

The aim of this study is to quantify and observe the morphology of trabecular meshwork (TM), Schlemm's canal (SC), ciliary body and crystalline lens before and after cycloplegia in patients with different ages using swept-source optical coherence tomography.

Treatment and study plan

swept-source optical coherence tomography

Device

Aswe pt-source OCT (CASIA SS-1000; Tomey Corporation, Nagoya, Japan), which is specifically designed for anterior segment imaging using a 1310 nm wavelength with a scan speed of 30,000 A-scans per second and an axial resolution of <10 μm.

Primary outcomes

  1. area of Schlemm's canal and trabecular meshwork

    Time frame: up to 6 months

    The area of Schlemm's canal and trabecular meshwork was manually measured and the relationship between the parameters and age was analyzed.
