Optical coherence refraction tomography
WebAssessment of the peripapillary retinal nerve fiber layer (RNFL) thickness is an important component in detecting structural damage in patients with glaucoma. Imaging devices such as optical coherence tomography (OCT) allow for the quantitative and objective assessment of the peripapillary RNFL thickness. 2 Multiple studies have shown that ...

WebOptical coherence refraction tomography. Optical coherence tomography (OCT) is a cross-sectional, micron-scale imaging modality with widespread clinical application. Typical OCT systems sacrifice lateral resolution to achieve long depths of focus for bulk tissue imaging, and hence tend to have better axial than lateral resolution.
WebOCT utilizes technology that is similar to CAT scans of internal organs, using a scattering of light to rapidly scan the eye to create an accurate cross-section. OCT also measures the …
