Abstract PURPOSE: To evaluate clinical and angiographic differences in patients with Vogt-Koyanagi-Harada (VKH) disease during the early 4-month treatment phase with high- or medium-dose systemic corticosteroid therapy. METHODS: VKH patients treated at the Centre for Ophthalmic Specialized Care, Lausanne, Switzerland (n = 4), or the Department of Ophthalmology, Tokyo Medical and Dental University, Tokyo, Japan (n = 5), underwent a pre-treatment indocyanine green angiography (ICGA) and a follow-up ICGA four months after treatment began. Lausanne patients received high-dose, systemic corticosteroid therapy, with or without immunosuppressive therapy. Tokyo patients received medium-dose systemic corticosteroid therapy that included 3 days of intravenous pulse methylprednisolone. ICGA signs including choroidal stromal vessel hyperfluorescence and leakage, hypofluorescent dark dots (HDD), fuzzy vascular pattern of large stromal vessels and disc hyperfluorescence were retrospectively compared. RESULTS: The pre-treatment ICGA demonstrated that each of the nine patients had choroidal inflammatory foci, as indicated by HDD. At 4-month follow-up, clinical and fluorescein findings had improved almost equally in both groups. HDD had resolved in the Lausanne group but persisted in the Tokyo group. Sunset glow fundus occurred in three of the Tokyo patients and none of the Lausanne patients. CONCLUSIONS: Submaximal doses of inflammation suppressive therapy are sufficient to suppress clinically apparent disease but not the underlying lesion process. This explains the propensity for sunset glow fundus in seemingly controlled disease.
