Iridociliary measurements using the Anterion swept-source optical coherence tomography

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Anterior segment optical coherence tomography (AS-OCT) using swept-source technology offers advanced visualization capabilities.
• Accurate measurement of ocular structures is crucial for diagnosing and managing various eye diseases.

Purpose of the Study:

• To evaluate the feasibility of a new swept-source OCT device (Anterion) for measuring key anterior segment parameters.
• Specifically assess the device's ability to measure iris ciliary sulcus, ciliary body thickness, and iris thickness.

Main Methods:

• A pilot study involving 30 healthy young participants and hospital employees was conducted.
• Measurements of iris thickness (at two locations), ciliary body thickness, and iridociliary sulcus were performed using the Anterion device.
• Data quality was assessed, with 28 participants providing good-quality results for analysis.

Main Results:

• The Anterion device provided reliable measurements for iris thickness, ciliary body thickness, and iridociliary sulcus.
• Specific measurements included iris thickness (e.g., 0.70 ± 0.10 mm at 2.5 mm from the pupillary margin) and ciliary body thickness (0.59 ± 0.14 mm).
• Iridociliary sulcus angles were recorded as approximately 82.65 ± 26.6° (right eye) and 83.66 ± 30.1° (left eye).

Conclusions:

• The Anterion swept-source OCT device is feasible for anterior segment measurements in a clinical setting.
• The device provides valuable data that can aid ophthalmologists in patient diagnosis and treatment planning.
• This technology holds promise for enhancing the management of ocular conditions.
