OCT angiography is a recent evaluation of OCT technology which combines the structural assessment of ocular tissues obtained by OCT image with visualization of blood flow within the vessels in imaged area. So combined structural and function image can be obtained by OCT angiography.
Defferent type of uveitis often have specific OCT \& OCT angiography findingwhich deffer according to the involved ocular tissue and according to the type of inflammatory / infectious process that characterize them.
The aim of study is to determine the role of OCT \& OCT angiography in assessment of retinal and choroidal architectural and vascular changes in patients with posterior uveitis.
