352 La tomographie par cohérence optique du segment antérieur comme outil diagnostique d’une cyclodialyse traumatique

Abstract

Introduction To evaluate the ability of the Optical Coherence Tomography to provide anterior segment imaging to diagnose traumatic cyclodialysis and to correlate it with the clinical examination and ultrasound biomicroscopy. Material and Methods A patient with post-traumatic hypotonus maculopathy, reduced vision and suspected cyclodialysis cleft was examined with slit-lamp biomicroscopy, gonioscopy, ultrasound biomicroscopy and anterior segment Optical Coherence Tomography. Observation Anterior segment Optical Coherence Tomography provided high-resolution images of the disinsertion of the ciliary body from the scleral spur and associated ciliary body detachment that served to confirm the diagnosis and helped substantially in the descision making process. Discussion Anterior segment Optical Coherence Tomography is a non-invasive tool that does not require any contact with the patient's eye. It provides accurate and reproducible images of the anterior segment. This technique has a good correlation to ultrasound biomicroscopy, allows observing iridocorneal angle abnormalities in the presence of turbid media and is more comfortable for the patient. Conclusion Anterior segment Optical Coherence Tomography is a non-invasive method that can diagnose abnormal anterior segment anatomy, in our case traumatic cyclodialysis.
