Projects from Boston and Portland could help translation of OCTA into clinics. Retina blood flow: vital for diagnosis Optical coherence tomography angiography (OCTA) is a promising technique for imaging of blood vessels, in which sequential OCT scans of the same tissue cross-section reveal the sites of blood flow within those tissues, and can allow the blood oxygen content to be calculated. Examination of the retina is one promising application area for OCTA, thanks partly to the widespread adoption of conventional OCT within ophthalmology and its established place in clinical workflows. Two recent projects have published findings that could assist the ...

Several diseases of the cornea, such as corneal dystrophy and keratoconus, lead to underlying changes in a cornea's intrinsic biomechanical properties as well as the inherent cellular damage. Measuring those biomechanical markers could be a valuable tool for monitoring and detecting the diseases, especially if the technique can be a non-contact method. Non-invasive measurement methods are inherently likely to be best suited for eventual translation into clinics, and for reducing patient discomfort. Optical coherence elastography (OCE), in which optical coherence tomography is used to image tissue while it is under some form of transient local mechanical deformation and subsequent ...

Optical coherence tomography has become a standard technique in ophthalmology, thanks to its easy fit with clinical workflows and the ability to image particular zones of the eye, such as the anterior chamber and the cornea. Use of the same technique to image the whole eye has proved challenging. OCT's limited imaging depth can be improved though Fourier domain methods and use of modern swept-source laser sources, but the optics of the eye prevent the focusing of light on both the anterior chamber and the retina simultaneously without sacrificing resolution. A project from Poland's Nicolaus Copernicus University and ...
