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

Description

It is not excessive to say that retinal imaging has enjoyed a revolution in the last 15 years. The arrival and widespread use of optical coherent tomography (OCT) have revolutionised the diagnosis and follow-up of macular diseases. This revolution has been made possible thanks to technological advances [time-domain OCT (TD-OCT), then spectral- domain OCT (SD-OCT)] and thanks to the fact that they have become accessible to a large number of centres and physicians worldwide. This revolution has been driven by substantial progresses in treatments, especially with the arrival of corticosteroids and anti-VEGF administered by intravitreal (IVT) injections. Almost 10 years have now past since the initial widespread use of IVT injections and almost 7 years since the marketing of SD-OCT. We thought that it would be of interest to produce a book depicting a number of characteristic images of macular diseases. In collaboration with Marie-Bénédicte ROUGIER, MD, PhD and Marie-Noëlle DELYFER, MD, PhD we have collected the most typical and interesting cases, without seeking to include all of the possible macular diseases. The reader will browse this book and will easily be able to recognise some diseases, keeping in mind that an accurate and complete analysis of all OCT images is required. In fact, in everyday practice, it is easier just to quickly study one single OCT scan, which is a potential source of error. Indeed, it is not one single OCT image but numerous sections that need to be analysed, together with retinal mapping and “en-face” OCT images. These OCT images must be carefully correlated with the fundus examination (posterior pole and periphery), the visual acuity, and the patient’s medical history in order to make the correct diagnosis and the appropriate treatment decision. Depending on the case, other imaging techniques may complement OCT, such as retinal fluorescein and indocyanine green angiographies, or autofluorescence retinal imaging. We are grateful to ZEISS and Laboratoires Théa who supported this initiative and permitted the free distribution of this book. We hope that it will help refresh your knowledge of diseases of the retina. We hope you will enjoy reading this book.
