To illustrate the pathomorphologic features of patients with myopic macular changes using the three-dimensional (3D) optical coherence tomography (OCT).
The TOPCON 3D OCT -1000 based on the Fourier -domain spectrometer technology integrated with the TOPCON non-mydriatic camera, was used for patient examination. It employs the use of a superluminescent light emitting diode, which has a wavelength of 840nm. The OCT system records the interferometric information using a Fourier domain spectrometer method, with an acquisition rate of 20 000 axial scans/sec, axial resolution of 5µm and a lateral resolution of 20µm. Three dimensional images of the macular pathology and corresponding simultaneous acquisition of OCT fundal photos were obtained for all patients.
3 eyes of 3 patients were illustrated in this preliminary case series. Myopic retina schisis in one of the patients and macula hole detachment in 2 of the myopic patients were clearly demonstrated in a multidimensional view which was not possible with only the 2D-OCT view. This has enabled proper confirmed diagnosis and management through the three-dimensional images of the topographical dynamics of the intraretinal layers and connections.
Three dimensional OCT imaging using the fourier domain system has enabled unprecedented precise views of macular pathology facilitating our understanding and visualization of the pathology of macular diseases. This multidimensional view of retina structures will aid us in early detection and monitoring of disease progression in the future.
