Subfoveal serous retinal detachment often causes to the visual loss in tilted disc syndrome (TDS). Although the chorioretinal expansion of posterior staphyloma has been thought to lead to the retinal detachment, the pathophysiology of TDS is not completely understood. To examine the chorioretinal alteration at the macular area in TDS with posterior staphyloma using optical coherence tomography.
All eyes were evaluated by fluorescein and indocyanine green angiography (FA and IA), and confirmed with or without serous retinal detachment using optical coherence tomography (OCT). The choroidal thickness was measured at the upper area, fovea, and lower area on the vertical section of OCT.
Twenty-four eyes of thirteen patients with the edge of the posterior staphyloma at the macular area were included in this study. Mean best-collected visual acuity was 0.54, and mean spherical equivalence was -4.47 diopters. Seven eyes had serous retinal detachment. Macular area with staphyloma edge showed the granular pattern of hyperfluorescence in FA and belt-like hypofluorescence in IA. Mean choroidal thickness on vertical section of OCT was 220±95µm at the upper area, 174±84µm at the fovea, and 190±64µm at the lower area. Subfoveal choroidal thickness was significantly thinner than others (P<0.05, respectively).
Subfoveal choroidal thickness at the edge of the posterior staphyloma in TDS was relatively thin. That area showed the retinal pigment epithelium atrophy presented the hyperfluorescence in FA and the occlusion of choriocapillaris represented the hypofluorescence in IA. Morphologic alteration might cause the thinner choroid and the abnormality of choroidal circulation, and secondary retinal pigment epithelium disorder subsequently could induce serous retinal detachment.
