    Abstract:
    PURPOSE: To study the relationship of choroidal abnormalities with serous retinal detachment (SRD) in eyes with staphyloma, dome-shaped macula, or tilted disk syndrome. METHODS: Group 1, 28 eyes of 20 patients with staphyloma/dome-shaped macula/tilted disk syndrome associated with SRD was compared with Group 2, 30 eyes of 20 patients, with staphyloma/dome-shaped macula/tilted disk syndrome but without SRD. Radial and en-face optical coherence tomography and choroidal analysis were performed. RESULTS: Group 1 had a thicker mean subfoveal choroidal thickness (161 μm vs. 92 μm, P < 0.05) and a greater variation in choroidal thickness (112 μm vs. 76 μm, P > 0.05) compared with eyes of Group 2. Focal abrupt changes in choroidal thickness were more commonly seen in Group 1 versus eyes in Group 2 (90% vs. 30%, P < 0.05) and this area of abrupt change was located within or at the edge of the SRD in 64% of eyes. Large choroidal vessels (pachyvessels) (82% located within the area of SRD) were always associated with the presence of SRD. CONCLUSION: An abrupt transition in choroidal thickness may be involved in the pathogenesis of SRD. In some cases, a radial scan pattern may better demonstrate mild SRD, choroidal contours and the focal choroidal variations than horizontal or vertical raster scan patterns.
