Morphologic Characteristics of Macular Complications of a Dome-Shaped Macula Determined by Swept-Source Optical Coherence Tomography

Comparison of Clinical Features in Highly Myopic Eyes with and without a Dome-Shaped Macula

“…This confirmed earlier studies showing that a horizontally oriented DSM was by far the most common type of DSM, 3,4 although there is some inconsistency among earlier studies whether only bidirectional DSMs were included as DSMs 1,2 or whether horizontally oriented DSMs were also included. 3,4,7 Vertically oriented DSMs were seen in only 5 eyes. The vertical ridge in Curtin's type IX staphyloma should be differentiated from vertically oriented DSMs, especially when the ridge exists close to the optic disc.…”

“…For the Cirrus OCT, vertical and horizontal line scans 6 mm in length and centered on the fovea were obtained. The technique of the enhanced-depth imaging OCT 17 7 The dome height was measured as the distance between the peak of the bulge to a line tangential to the RPE. The choroidal thickness was defined as the distance from Figure 1.…”

“…Imamura et al 2 used enhanced-depth imaging OCT and showed that the DSM resulted from a relative localized thickening of the sclera under the macula in highly myopic eyes. A DSM has been reported to be associated with various kinds of macular complications, such as a serous retinal detachment (RD), 1,3e7 choroidal neovascularization (CNV), 1,3,4,6,7 and retinoschisis (RS). 4 However, there are still some uncertainties regarding DSM.…”

Characteristics of Peripapillary Staphylomas Associated With High Myopia Determined by Swept-Source Optical Coherence Tomography

“…[10][11][12][13] Current swept-source OCT instruments use a longer central wavelength, generally in the 1 µm range, which has improved their ability to penetrate deeper into tissues than the conventional spectral domain OCT instruments. Due to its deep penetration, swept-source OCT can obtain images of deeper tissues, such as the choroid, sclera, and optic nerve, more clearly.…”

Complications of Pathologic Myopia

“…52 Progressive asymmetric scleral and choroidal thinning may be also found in the dome-shaped macular region, which can increase the macular bulge height and lead to development of CNV causing visual impairment. 50,53 Recently, photodynamic therapy (PDT) has been used as treatment of subretinal fluid or CNV combined with domeshaped macular features. 54 …”
