OCT & Glaucome () by Pr Jean-Paul Renard PDF

Description

Identification of structural changes of the retinal nerve fibre layer (RNFL), optic nerve head (ONH) and macular ganglion cell complex (GCC) is an essential component of the diagnosis and management of glaucoma. Optical coherence tomography (OCT), which has been used in ophthalmology for more than 25 years, allows in vivo examination of all layers of the retina. New SD-OCT (Spectral-Domain OCT) systems now provide continually improving objective quantification of lesions of these structures. The use of recently available new image acquisition and new image analysis algorithms on larger tissue volumes now allows a higher level of diagnostic precision of the parameters obtained, as well as more reliable interpretation of the features of certain clinical forms at the various stages of glaucomatous optic neuropathy. Lastly, the development of OCT angiography, providing «en face» visualization of the capillary architecture and clear distinction of the deep and superficial capillary plexuses, provides perspectives with various interesting extensions. The contribution of OCT angiography, in terms of its objective to evaluate the dynamic aspects of the tissues in addition to tissue morphology, needs to be more clearly defined.
