Peran Pencitraan dalam Diagnosis Uveitis

Uveitis is an inflammatory disease affecting iris, ciliary body, pars plana, vitreous, choroid and retina.Inflammation process can be either limited in uveal tract or as part of systemic inflammation caused byautoimune, infection or cancer. Uveitis can cause phophobia, pain, reduced visual accuity and blindness if notproperly treated. Therefore, right diagnosis and prompt treatment should be given immediately to reduce themorbidity. Diagnosis of uveitis is made based on anamnesis, ophtalmic and physical examination, followedby imaging to confirm the patologic changes in the eyes. Slit lamp and simple photography can be usedto evaluate sign of inflammation in anterior chamber and outer part of the eye. Inflammation marker canbe counted using laser flare photometry (LFP) and fundus fotography can visualize pathologic changes inposterior part of the eyes. Fundus fluorescein angiography (FFA), indocyanine green angiography (ICG), andfundus autofluorescence (FAF) can be used to evaluate the integrity of vascular part in retina and choroid.Ultrasound (USG), optical coherence tomography (OCT), and multimodal imaging visualize retina, choroid,optic nerve and nerve fiber layer of retina using non-contact and non-invasif technique. MRI also used toevaluate inflammatory process in the eye. These imaging modalities are usefull to confirm the diagnosis ofuveitis, monitor the disease progression and evalute the treatment.
