MULTI-MODAL IMAGING IN DIFFUSE SUBRETINAL FIBROSIS WITH UVEITIS SYNDROME.

Abstract

To describe clinical features including multimodal imaging in a case of diffuse subretinal fibrosis and uveitis syndrome. A young patient presented with counting fingers in both eyes due to posterior uveitis and unresponsive to systemic corticosteroids. Ultra-wide field pseudo-color and autofluorescence imaging, optical coherence tomography angiography (OCT-A), en-face OCT-A, and spectral-domain optical coherence were performed. Clinical examination revealed a bilateral fibrosis plaque in both fovea and macular multifocal choroidal lesions associated, with no vitritis. Ultra-wide field-autofluorescence allowed us to determine activity showing a hyperfluorescent pattern. En-face OCT-A at the level of the ellipsoid layer showed multiple hyperreflective lesions surrounding a hyperreflective fibrosis plaque in both eyes, which improved and stabilized during the follow-up. Optical coherence tomography angiography at the level of retina pigmentary epithelium-choriocapillaris revealed neocapillary network changes along the chronification of the disease. The patient required the addition of intravitreal dexamethasone implants (Ozurdex) to control the acute rebounds and anti-TNFα to control the underlying inflammatory process. This is the first diffuse subretinal fibrosis with uveitis syndrome reported with a complete En-face OCT-A and OCT-A examination. This multi-modal imaging will improve the monitoring of the disease's activity and the chronicity changes.
