The diagnosis of uveitis serves on the one hand for the exact evaluation, as well as for the clarification of the cause. With the help of elaborate examination procedures, we first of all evaluate which areas of the eye are affected at all, i.e. whether it is anterior, intermediate or posterior uveitis, or whether all areas of the eye are affected (so-called panuveitis). This initial examination includes a detailed eye examination, of the anterior as well as the posterior eye segment, as well as a detailed medical history. In the next step, we perform ophthalmological imaging for further customized clarification of our patients. This includes optical coherence tomography, photos of the ocular fundus and the anterior segment of the eye, optical coherence tomography angiography as well as more invasive examinations such as fluorescein angiography and indocyanine angiography, in which various dyes are injected intravenously to examine inflammation of the retina, retinal vessels, optic nerve, or choroid. Depending on the findings, we then arrange for further, often interdisciplinary clarification. This may include blood sampling, conventional x-rays, magnetic resonance imaging, visual field examinations, electroretinogram, but also the removal of eye fluids from the anterior or posterior segment of the eye. This step-by-step diagnosis allows us to clarify and care for our uveitis patients in a targeted and individualized manner. Every next diagnostic step, as well as the findings obtained, are discussed in detail with our patients.
