OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FEATURES OF FOCAL CHOROIDAL EXCAVATION AND THE CHOROIDAL STROMA VARIATIONS WITH OCCURRENCE OF EXCAVATION
Purpose: To describe retinal and choroidal vascular changes and choroidal stroma variations occurring in focal choroidal excavation (FCE). Methods: Study design was a cross-sectional case series. Consecutive patients affected by FCE and healthy controls were recruited. All patients underwent complete ophthalmologic assessment and multimodal imaging, including structural optical coherence tomography and optical coherence tomography angiography. Choroidal thickness and stromal index were calculated from structural optical coherence tomography images. Moreover, we measured vessel density values of superficial capillary plexus, deep capillary plexus, and choriocapillaris at the level of the macula. Results: Twenty-two patients (28 eyes; mean age 57.2 ± 16.4 ...
