Focal choroidal excavation: Cause or effect?

Author information

Department of Vitreo-Retina, Giridhar Eye Institute, Ponneth Temple Road, Kadavanthra, Cochin, Kerala, India.


We report the imaging characteristics of focal choroidal excavation (FCE) and associated choroidal neovascular membrane (CNVM) and interpret the probable etiopathogenesis of FCE through findings in four patients detected by spectral-domain optical coherence tomography (SD-OCT). FCE was found as an acquired entity in two of our cases subsequent to treatment of CNVM, whereas in the two other cases FCE was pre-existing. Furthermore, association of FCE with pachychoroid spectrum is reaffirmed through this case series.
