Contribution of "en face" SD-OCT in inflammatory diseases
2014
To evaluate the retinal and choroidal changes in White Dot syndromes (WDS) using ‘’en face’’ and B-scan OCT images. All the study patients underwent a comprehensive ophthalmologic examination including biomicroscopic fundus examination, color photography, fundus autofluorescence, fluorescein angiography, indocyanin green angiography and B scan and "en face" SD-OCT. A total of 10 patients with Multiple evanescent white dot syndrome (MEWDS), 4 cases diagnosed with acute posterior multifocal placoid pigment epitheliopathy (AMPPE), 1 case of serpiginous choroidopathy, 4 cases of multifocal choroiditis, 3 cases of punctuate inner choroidopathy (PIC) and 3 cases diagnosed with Birdshot disease were analysed and included in the study. The B-scan findings were correlated with the angiography findings as well as with the ‘’en face’’ OCT scans. In all the cases the ‘’en face’’ OCT, providing a layer-by-layer view of the involved retina, enabled depicting in detail the IS/OS envolvement and the extent of the outer retinal damage. The patho-physiologic mechanism of the WDS remains poorly understood. All these entities probably share a common pathway leading to external retinal involvem
