High-penetration imaging of retinal and choroidal pathologies by 1 _μm swept-source OCT and optical coherence angiography

摘要

Two pathologic cases are evaluated by high-penetration optical coherence tomography (HP-OCT) to demonstrate its clinical significance. The HP-OCT is based on a swept-source OCT (SS-OCT) technology with a probe wavelength of 1.06 μm. The depth resolution is 10.4 μm in tissue, and the measurement speed is 28,000 depth-scans/sec. A single case of age-related macular degeneration and a single case of Vogt-Koyanagi-Harada disease are examined by HP-OCT.
