Unlike UBM, OCT Biomicroscopy can image tissues with high axial
Traditionally, ophthalmic Biomicroscopy has been completed with a slit lamp
Like slit lamp Biomicroscopy, OCT does not penetrate opaque tissues well
Until recently, OCT hardware limitations have made OCT Biomicroscopy difficult or impossible.
The major limitation of TD-OCT that prevents its use for OCT Biomicroscopy is speed.
Ultrasound Biomicroscopy(UBM) is much better at imaging
through opaque tissues since it uses high energy sound waves.
Like slit lamp Biomicroscopy, OCT does not penetrate opaque tissues well
but enables detailed, cross-sectional views of transparent tissues,
therefore can cover the required tissue volume for OCT Biomicroscopy in a single eye in approximately eight minutes assuming
The development of short external cavity tunable
laser technology has made SS-OCT Biomicroscopy possible by combining high speed acquisition
with long coherence length and consistently high image quality across the depth of the eye.
Traditionally, ophthalmic Biomicroscopy has been completed with a slit lamp
biomicroscope that uses slit beam illumination and an optical microscope to enable stereoscopic, magnified, cross-sectional views of transparent tissues in the eye, with or without the aid of an additional lens.
