segment complications, for example cataract, synechia, corneal opacities, and glaucoma; intermediate and posterior uveitis cause posterior segment complications that are the culprits in visual morbidity. Posterior segment complications of uveitis include macular oedema, exudative retinal detachment, CNVM, occlusive retinal vasculitis, and ischemia. Given the major contribution of posterior segment complications in myriad types of uveitis, B-scan OCT and OCTA can be of help in the detection and follow-up of such complications with an accurate characterization of macular oedema, areas of vascular drop-outs, for example ischemia at the different ocular vascular beds, such as the superficial and deep macular vascular plexuses and choriocapillaris. A significant limitation of OCTA in posterior uveitis and retinal vasculitis is the small field of imaging which may not appreciate peripheral retinal involvement which is not only common but also important in proper management like delineating peripheral ischemic retinal zones for subsequent retinal photocoagulation. Therefore, a multimodal imaging approach including wide-field dye-based angiography combined with B-scan OCT and OCTA is a must for proper and comprehensive management of uveitis which mirrors the multidisciplinary approach to uveitis diagnosis [19–21].
