TitreThree-dimensional optical coherence tomography of optic nerve pathology: a comparative illustration and discussion
ButTo analyse and discuss the imaging of prevalent and serious optic nerve pathologies using three-dimensional Optical Coherence Tomography (3D OCT) in contrast to other imaging modalities.
MéthodesThe following imaging modalities were used to illustrate, compare and contrast optic nerve pathology: 3D-OCT, 2D OCT and colour imaging. A selection of optic nerve conditions of papilloedema, myopia, optic disc pit and disc drusen are presented in comparison to the normal physiological state. The images were carefully selected, annotated and described to clearly demonstrate the most striking deviations. Analysis of the underlying architectural pathology using 3D OCT technique and measurements allowed us to evaluate this modality as a diagnostic tool.
RésultatsThe data we report are based on the analysis and evaluation of 3D OCT in imaging prevalent optic nerve conditions. The high-resolution of 3D OCT makes it a useful diagnostic tool with a high power for pathological detection, such as revealing subtle areas of subretinal fluid that may be overlooked on ophthalmoscopy and fundus fluorescein angiography. However, it was noted that 3D OCT should still be used in conjunction with other imaging modalities for a comprehensive pathological evaluation.
ConclusionAt present, 3D OCT has been widely documented and applied in imaging, diagnosing, staging, managing and follow up of retinal pathology. Optic nerve pathology imaging has equal potential.
