목적 : To describe the clinical and spectral-domain optical coherence tomography (SD-OCT) findings in 41 eyes of 38 patients with focal choroidal excavation (FCE) identified in Yonsei Univeristy College of Medicine Severance Hostpital and Seoul National University Bundang Hospital.
방법 : Clinical features, SD-OCT findings, and associated macular disorders of FCE were analyzed and detailed. Main outcome measures include statistical associations among clinical features, including lesion type, size, and choroidal thickness, and frequency of association with central serous chorioretinopathy (CSC), choroidal neovascularization(CNV), and polypoidal choroidal vasculopathy (PCV).
결과 : The mean age was 50.1 years. There was a positive correlation between lesion width(mean,757µm) and depth(mean,107µm)(P=0.003). The mean subfoveal choroidal thickness was not statistically different from that of age-, sex-, and refractive error-matched normal subjects. Nonconforming FCE was associated with visual symptoms(P<0.001) and the presence of concurrent CSC(P=0.001). Ten eyes(24%) were associated with CSC, and 9 eyes(22%) were associated with CNV, including a PCV. One type 1 CNV eye developed a new excavation, and the excavated area in 1 eye with PCV enlarged slighly during follow-up.
결론 : Focal choroidal excavation is a relatively common entity and frequently associated with choroidal diseases, including CSC, CNV, and PCV. Although FCE is classically thought to be a congenital malformation, acquired
FCE forms possibly exist.
