Focal choroidal excavation associated with focal retinochoroiditis

To describe detailed spectral-domain optical coherence tomography (OCT) findings for two patients with focal choroidal excavation (FCE) associated with focal retinochoroiditis.

Three eyes from two patients with FCE associated with focal retinochoroiditis were evaluated by funduscopy, fluorescence angiography, indocyanine green angiography, and spectral-domain OCT during follow-up. Both patients with focal retinochoroiditis developed new FCE after oral steroid treatment and two eyes showed regression of the FCE during the follow-up. Both eyes from one patient transformed from the conforming to the nonconforming type and neither of the eyes were stable during the follow-up. Ultimately, all eyes exhibited the conforming-type FCE.

Focal choroidal excavation can be seen as a tomographic phenotype after the treatment of focal retinochoroiditis. Spectral-domain OCT was useful for detecting the development of FCE after the treatment and for observing FCE regression.
