Abstract

Purpose : To describe the optical coherence tomography - angiography (OCT- A) findings in patients with uveitis related neovascularization

Methods : We included in this prospective descriptive case series, all patients diagnosed with inflammatory neovascularization (CNV) at the Pitie Salpetriere hospital between 09/01/2016 and 15/11/2016. All patients were assessed including best corrected visual acuity, clinical inflammatory parameters, multimodal imaging, fluorescein angiography, ICG and SD-OCT or SS-OCT. They underwent OCT angiography with SS-OCT DRI Triton (Topcon, Japan) or/and Spectralis Angiography OCT (HRA, Heidelberg, Germany). OCT-A images were analyzed and compared with en face and B-OCT.

Results : Six patients (7 eyes), 3 women and 3 men, with a mean age of 55 years, were included. Three patients were diagnosed with ocular sarcoidosis and the others with Birdshot retinochoroidopathy, HSV-2 uveitis and ocular tuberculosis. OCT-A revealed inflammatory pre retinal pigment epithelial CNV in all cases. Three lesions were localized in the papillo-macular region and four close to the vascular arcades. The main length of the major axis was 2.806 microns. All lesions presented a sea fan pattern with an anastomotic network and a thin capillary network surrounded by a dark halo. They were attached to a single or to multiple thick branches. Two patients had a follow-up of one month after anti-VEGF therapy confirming the rapid fibrosis of these vessels. The characteristics of inflammatory CNV seem to differ from those of CNV in neovascular age related macular degeneration scanned with OCT-A. The branching seems to be less important, and capillaries thinner and pedicles thicker.

Conclusions : OCT-A is a new additional imaging method for the diagnosis of inflammatory CNV. The features and the evolution of these lesions need to be investigated in further studies.
