Multimodal imaging of focal choroidal excavation and macular choroidal cavitation associated to choroidal neovascularization.

Purpose: To report multimodal imaging features of an unusual case of multiple focal choroidal excavations (FCE) associated to macular intrachoroidal cavitations (ICC) and choroidal neovascularization (CNV) in a non-myopic patient with normal choroidal thickness. Methods: Observational case report. Results: A 69-year-old non-myopic male patient with history of macular CNV of unknown etiology in the right eye (RE), initially treated with Bevacizumab intravitreal injections with significant improvement of visual acuity. He presented with acute vision loss in the same eye related to recurrent CNV exudation. Multimodal imaging of the RE confirmed the diagnosis of active type 2 CNV, associated to multiple FCE. Besides, it highlighted incidental unusual macular ICC in the same eye. Choroidal thickness was within normal limits (217 μm). Conclusion: Focal choroidal excavations and intrachoroidal cavitations can be observed in emmetropic patients in the absence of pachychoroid disease. In presence of CNV of unknown etiology, complete multimodal imaging can be of a great help to better define choroidal anomalies, allowing structural and vascular correlations between different lesions.
