| High myopia is associated progressive, excessive elongation of the globe often followed
by degenerative changes involving the sclera, choroid, Bruch membrane, RPE and sensory retina. Retinal changes
associated with myopic maculopathy were previously studied by time-domain optical coherence tomography
(OCT). Recently, TOPCON Fourier-domain OCT (FD-OCT) has been introduced to clinical diagnose. FD-OCT
provides increased scan resolution、scanning speed、scan area, and generates three-dimensional (3D) OCT images.
PURPOSE：To demonstrate features of myopic maculopathy assessed with high-density scanning 3D-FD-OCT
(Topcon 3D-OCT1000). METHODS: The study was designed as a prospective, observational case series. Ten
consecutive patients with typical myopic maculopathy were choosed based on fundus findings. All tested eyes had
refractive error of -6D or more. 3D-FD-OCT images were obtained from the ten eyes with myopic maculopathy of
the ten patients, and include eyes with retinal detachment. RESULTS: FD-OCT provided detailed 3D-images of
retinal structure. In addition, FD-OCT showed improved retinal coverage and image quality. FD-OCT B-scan
imaging identified typical retinal changes associated with myopic maculopathy. In addition, FD-OCT imaging
revealed information about the extent and the 3D shape of retinal lesions. CONCLUSION: 3D-FD-OCT imaging is
useful for assessing and following up patients with myopic maculopathy. In addition, 3D-FD-OCT provided
information about the extent and 3D shape of retinal pathologies and showed improved retinal coverag |
