Videofunduscopy and videoangiography using the scanning laser ophthalmoscope in Vogt-Koyanagi-Harada syndrome.

AIM: To observe pathophysiological changes in patients with Vogt-Koyanagi-Harada (VKH) syndrome using the scanning laser ophthalmoscope (SLO) to perform videofunduscopy, and indocyanine green (ICG) and fluorescein videoangiography. METHODS: 18 patients diagnosed with VKH syndrome were studied. 15 patients were examined in both acute and convalescent phases, and three patients were examined in the convalescent phase only. Retrospective review of charts was performed to obtain data on visual acuities, clinical findings, and results of cerebrospinal fluid cytology and histocompatibility leucocyte antigen D locus testing. RESULTS: Videofunduscopy revealed abnormalities in the central macula at the level of the retinal pigment epithelium or choroid in 40% of patients in the acute phase and 83% of patients in the convalescent phase. ICG videoangiography showed irregular hypofluorescence (80%), slow or patchy filling (67%), indistinct or fewer choroidal vessels (73%), filling defects (73%), and focal leakage (33%) in patients in the acute phase. These changes improved with systemic corticosteroid treatment, although at least one ICG videoangiographic abnormality persisted into the convalescent phase in 83% of patients in the absence of clinical inflammation. In contrast, fluorescein videoangiography revealed fewer and decreased severity of abnormalities, with greater resolution in the convalescent phase when compared with ICG videoangiography. CONCLUSIONS: SLO videofunduscopy and videoangiography revealed numerous abnormalities in patients with VKH syndrome, many of which persisted well after clinical recovery, suggesting the development of permanent morphological changes in the fundus. ICG videoangiography was more sensitive than fluorescein videoangiography in delineating abnormalities in layers deep to the sensory retina.[1]
