Enhanced Vitreous Imaging in Uveitis

Abstract

ABSTRACTPurpose: To study the structural visibility of the posterior vitreous cavity and vitreoretinal interface using Spectral Domain–Optical Coherence Tomography in patients with uveitis using conventional, Enhanced Depth Imaging (EDI), Combined Depth Imaging (CDI), and Enhanced Vitreous Imaging (EVI) techniques.Methods: It was an observational cross-sectional study of 59 eyes of 33 patients between age group 12–72 years (Median 43) diagnosed as uveitis with posterior segment manifestations underwent OCT using conventional, EDI, CDI, and EVI techniques. The visibility of posterior vitreous was graded in all the techniques.Results: A statistically significant difference was seen in posterior vitreous visibility on comparing all four techniques. EVI showed better visibility of posterior vitreous cavity compared to all other techniques (P < 0.001).Conclusions: EVI technique provides better structural visibility of posterior vitreous compared to conventional, EDI, and CDI techniques.
