title: Pulsatile motion of trabecular meshwork in a patient with iris cyst by phase-sensitive optical coherence tomography: a case report.
abstract: A 45-year-old man was diagnosed with a 3 mm × 3 mm iris cyst located at 9 o'clock behind iris and protruding into temporal angle by slit lamp examination, gonioscopy, and ultrasound biomicroscopy (UBM). Phase-sensitive optical coherence tomography (PhS-OCT) was applied on this case for the quantitative measurements of trabecular meshwork (TM) motion. The frequency of TM motion was with the same rhythm of the patient's peripheral pulse. Its amplitude on the closed angle region showed significant smaller than the open angle region. PhS-OCT can be a useful tool for the diagnosis and follow-up in ocular diseases surrounding iridocorneal angle.
