The Quirks of Confocal Imaging
October 13, 2019 @ 2:50 pm - 3:20 pm
Timothy J. Bennett, CRA, OCT-C, FOPS. ATPO Grand Rounds.
This course will explore the principles of confocal imaging and potential enhancement of some ocular pathologies with this technology. The Heidelberg Spectralis confocal scanning laser ophthalmoscope (cSLO) is a diagnostic imaging device used for several imaging modalities including infrared reflectance (IR), blue reflectance, fluorescein angiography, ICG angiography and fundus autofluorescence (FAF). The confocal capability of the cSLO allows it to capture high-contrast, finely detailed images, but also can create a tonal shift related to focus.
- Describe the basic principles of the SLO and confocal aperture.
- Identify image artifacts related to the confocal aperture.
- Discuss the relationship between focus and reflectivity with the cSLO.
- List common clinical findings that can be enhanced with confocal imaging.
