摘　　要：Uveitis can cause significant visual morbidity and often affects younger adults of working age.Anterior uveitis,or inflammation limited to the anterior chamber(AC),iris,and/or ciliary body comprises the majority of uveitis cases.Current clinical biomarkers and conventional grading scales for intraocular inflammation are mostly subjective and have only a moderate degree of interobserver reliability,and as such they have significant limitations when used in either clinical practice or research related to uveitis.In recent years,novel imaging techniques and applications have emerged that can supplement exam findings to detect subclinical disease,monitor quantitative biomarkers of disease progression or treatment effect,and provide overall a more nuanced understanding of disease entities.The first part of this review discusses automated algorithms for optical coherence tomography(OCT)image processing and analysis as a means to assess and describe intraocular inflammation with higher resolution than that afforded by conventional AC and vitreous cell ordinal grading scales.The second half of the review focuses on anterior segment OCT and OCT angiography(OCTA)in scleritis and iritis,especially with regards to their ability to directly image and characterize the pathologic structures and vasculature underlying these diseases.Finally,we briefly review experimental animal research with promising but more distant human clinical applications,including in vivo molecular microscopy of inflammatory markers and investigation of gold nanoparticles as a potential contrast agent in OCT imaging.Imaging modalities are discussed in the broader context of trends within the field of uveitis towards greater objectivity and quantifiable outcome measures and biomarkers.
