Abstract
Purpose
To investigate the associations between macular complications and demographic, clinical, and optical coherence tomography characteristics (OCT) of highly myopic eyes with a dome-shaped macula (DSM).
Methods
We retrospectively analyzed the findings of 90 patients (167 eyes) with DSM who had vertical and horizontal OCT scans between January 2011 and June 2018. Demographic data, clinical characteristics, and OCT-derived morphologic parameters were determined, and the associations of these parameters with macular complications were evaluated.
Results
Among 167 eyes, the following patterns were observed: horizontally oriented DSM (71%), symmetric DSM (27%), and vertically oriented DSM (2%). Complications or abnormalities involving the macular area were detected by OCT in 63% (106/167) of the eyes. Specific complications were as follows: choroidal neovascularization (CNV) (37.1%), macular retinoschisis (9.0%), serous retinal detachment (RD) (7.8%), epiretinal membrane (4.2%), lamellar macular hole (3.0%), and macular hole (2.4%). The eyes with CNV had thinner choroid (P < 0.001) and lower macular bulge height (P = 0.04). The eyes with serous RD had thicker choroid (P < 0.001) and higher macular bulge height (P < 0.001). Serous RD was significantly more common when the macular height was greater than 250 μm (P = 0.001) and if the DSM pattern was vertical (P < 0.001).
Conclusions
A greater bulge height and thicker choroid in highly myopic eyes with DSM may be protective against the development of myopic CNV. A thicker choroid, a higher macular bulge (> 250 μm), and a vertical DSM pattern are associated with a risk of developing serous RD.
