Choroidal and Retinal Thickness of Highly Myopic Eyes with Early Stage of Myopic Chorioretinopathy: Tessellation

Figure 1

Examples of photographs of the posterior pole and spectral domain optical coherence tomography (SD-OCT) in highly myopic eyes. Fundus photograph (top left) and EDI-OCTs in the horizontal direction (bottom) and in the vertical direction (right). This is a tessellated fundus of a 21-year-old female with refractive error equal to −8.75 diopter and 27.24 mm elongation of the eye ball. Both horizontal (bottom) and vertical scans (right) across the fovea of this tessellated myopic eye. The yellow cross in the fundus photograph shows the scan protocol of high-resolution scan with enhanced depth imaging. The white and black dotted lines refer to the ETDRS auxiliary lines. The white concentric circles have diameters of 1.0 mm (inner), 3.00 mm (middle), and 5.0 mm (outer). Although the scan length was set to 6 mm, the actual measurements were stopped in loci of 5.0 mm because of a little missing image. The yellow double-headed arrows in OCT scans demonstrate the measured loci of the 500 μm intervals.
