This video presents a technical overview of the Heidelberg Spectralis OCT system, a multimodal retinal imaging platform that combines spectral-domain optical coherence tomography with confocal scanning laser ophthalmoscopy. The presentation reviews the main hardware components, including the scanning head, fixation and alignment system, light sources, detector modules, and control workstation. The signal pathway is outlined from retinal scanning and interferometric detection in OCT through A-scan and B-scan reconstruction, as well as confocal fundus image formation using scanning laser illumination.
Key topics include eye-tracking and image registration for repeated scans, scan pattern selection for macula and optic nerve head, retinal layer segmentation, and generation of thickness and change maps. Basic clinical applications are described at a conceptual level, such as monitoring age-related macular degeneration, diabetic retinopathy, and glaucoma through structural measurements of the retina and retinal nerve fiber layer. The content is intended for students, clinicians, and biomedical engineers interested in retinal imaging, ophthalmic device design, and medical imaging systems, and is provided solely for educational and informational purposes without diagnostic or treatment recommendations.
