PURPOSE: Dome-shaped macula (DSM) is characterized by an inward bulge in the macula, often associated with a myopic staphyloma. One complication of DSM is particularly studied: foveolar serous retinal detachment (SRD). This study analyzed the variations of optical coherence tomography angiography (OCT-A) decorrelation signal in cases of DSM with and without SRD.
METHODS: This was a retrospective study including twenty height eyes presenting with DSM. OCT-A scans were recorded, and the intensity of the choroidal decorrelation signal was quantified to analyze choroidal blood flow (CBF) in central, temporal, and nasal macular areas. The size of retinal pigment epithelium (RPE) atrophy was evaluated.
RESULTS: CBF in the central area was significantly greater in the SRD group than in the no-SRD group (7.00 × 105 vs. 2.58 × 105) (p = 0.0049). CBF appeared decreased in the subfoveal area compared with the periphery for patients without SRD (p = 0.0107). The size of RPE atrophy was 0.762 optic disc area ±0.87. RPE atrophy correlated very significantly with CBF (p = 0.0012).
CONCLUSION: A greater retrofoveolar CBF intensity is associated with the presence of SRD. These changes could reflect variations of CBF, and may represent a potential explanation for the pathogenesis of SRD in DSM.
