Abstract:

Focal choroidal excavation (FCE) is a newly recognized entity in recent years benefited from the wide use of optical coherence tomography (OCT). On fundus examination, the appearance of FCE was quite different, from slight pigment irregularity to yellowish white plaque. FFA revealed normal or window defect at the site of or around the FCE lesions. ICGA images in the early phase showed hypofluorescence, and medium to large choroidal blood vessels were visible. According to OCT images, FCE was divided into confirming and non\|confirming type. FCE was regarded to be a congenital choroidal abnormality based on the observations that FCE usually present without any other concomitant pathology and show little change during the follow\|up. Occasionally, complications such as choroidal neovascularization and central serious chorioretinopathy can develop.(Int Rev Ophthalmol, 2019, 43:  346-349)
