oCular Examination at Cell RESolution With Optical TransmissionTomography
Recruiting now · Not applicable
Conditions studied: Glaucoma Associated With Other Ocular Disorders
In brief
Understanding the pathogenesis of eye diseases has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems, such as optical coherence tomography (OCT), are limited in terms of resolution, acquisition speed or access to certain eye functions. Our team has participated in the development of a new generation of imaging technology known as optical transmission tomography (OTT), which enables imaging of the anterior parts of the eye with high cellular resolution, a wide field of view and reduced examination delay.
