CHOROIDAL CHANGES ASSOCIATED WITH SEROUS MACULAR DETACHMENT IN EYES WITH STAPHYLOMA, DOME-SHAPED MACULA OR TILTED DISK SYNDROME.

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.
