PARIS — En-face optical coherence tomography provides high-resolution images of longitudinal retinal layers, a leading retina specialist said here.

“Conventional [spectral-domain] OCT only provides anterior-posterior cross-section images, essentially showing the exudative reaction of new vessels. This new technology allows us to actually see the new vessels themselves, without injection of dyes,” Gabriel Coscas, MD, said at the meeting of the French Society of Ophthalmology.
Real-time video acquisitions or single-shot images can be obtained with the technology, and Dr. Coscas showed examples of occult choroidal neovascularization and polypoidal lesions.
“Previously, only [indocyanine green] allowed us to detect these lesions, but ICG has largely been abandoned as a technique,” Dr. Coscas said.
Multimodal imaging is crucial to optimize the diagnosis and follow-up of retinal pathologies. This new OCT modality represents a further advancement.
“It is also easy to operate, noninvasive and extremely fast in the acquisition of images. Less than 1 minute is sufficient to analyze the retina in depth, with unmatched accuracy and attention to detail,” Dr. Coscas said.
