Abstract
PURPOSE: Swept-source optical coherence tomography angiography (SS-OCTA) was used to detect the presence of macular neovascularization (MNV) in eyes with exudative central serous chorioretinopathy (CSCR). OBSERVATIONS: Case 1 is a 73-year-old man using prednisolone drops with 20/40 vision and a retinal pigment epithelial detachment (PED) associated with subretinal fluid (SRF) and no clinical signs of age-related macular degeneration (AMD) in his left eye. Three months after presentation he underwent SS-OCTA imaging that revealed MNV. He received a series of intravitreal anti-vascular endothelial growth factor (VEGF) injections and SS-OCTA imaging showed a decrease in the MNV lesion size with resolution of the SRF. VA improved to 20/25. Case 2 is a 65-year-old man with recent oral steroid use, presenting with 20/20 vision, a PED, SRF, and no evidence of AMD. SS-OCTA imaging at presentation revealed MNV, which worsened on interval SS-OCTA imaging after the patient deferred treatment. Intravitreal anti-VEGF therapy was then performed with resolution of the SRF and VA improved to 20/15. A total of six cases of type 1 MNV were diagnosed with CSCR. Most were men with a history of steroid or testosterone use and were treated with good response. CONCLUSIONS AND IMPORTANCE: SS-OCTA imaging provides a convenient non-invasive strategy for identifying CSCR eyes with MNV without the need for dye-based angiography.
