Optical Coherence Tomography (OCT) in Uveitis
Optical Coherence Tomography (OCT) machines are non-contact instruments that can provide micrometer (one one-thousandths) scale imaging of biological tissue. This allows excellent assessment of the white blood and inflammatory cells seen in uveitis, an inflammation of any or all parts of the uvea (iris, ciliary body, choroid).
Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy (CADASIL) Study
