Anterior Chamber Angle Imaging with Swept-Source Optical Coherence Tomography: Measuring Peripheral Anterior Synechia in Glaucoma

Anterior-Chamber Angle and Axial Length Measurements in Normal Chinese Children

“…Fourier-domain optical coherence tomography (FD-OCT) provides noncontact, quantitative measurements of the anterior chamber angle (ACA), and the examination is fast and well-tolerated. 5 In addition, FD-OCT captures high-resolution images of the microanatomic structure of the anterior chamber and may allow longitudinal comparisons to established baselines. Evaluation of angle-closure suspects by OCT has proved valuable in the early diagnosis and prevention of PACG.…”

Swept-source optical coherence tomography assessment of iris–trabecular contact after phacoemulsification with or without goniosynechialysis in eyes with primary angle closure glaucoma

“…With the development of anterior segment optical coherence tomography (AS-OCT), it is possible to image the anterior chamber and angles in a cross section 11 12. More recently, Lai and associates have reported the use of swept-source OCT (SS-OCT) for imaging and quantifying PAS 13. This latter modality has the advantage over AS-OCT in allowing circumferential assessment of the anterior chamber angles by simultaneously obtaining 128 cross-sectional radial scans across the anterior chamber at equal intervals (every 1.4°).…”

Optimising keratoplasty for Peters' anomaly in infants using spectral-domain optical coherence tomography

“…First, the resolution of retrocorneally attached tissue was limited in some dense corneal leukoma cases due to the low penetration depth of the 830 nm SD-OCT laser. Swept-source OCT allows for visualisation and reproducible measurements of the anterior segment of the eye;39 however, we still lack longer-wavelength OCT systems that would enable deeper penetration. Second, because this was a non-randomised study, surgeons knew before surgery that they would use OCT. A bias towards reducing intervention aggressiveness may therefore have affected the results.…”
