Outcomes of patients with acute Vogt-Koyanagi-Harada disease treated with intravenous corticosteroid pulse followed by the slow tapering of oral corticosteroid therapy.

PURPOSE

To elucidate the intravenous corticosteroid pulse treatment outcomes of patients with acute Vogt-Koyanagi-Harada (VKH) disease and assess the differences between patients with no inflammation worsening and those with persistent or worsening inflammation. Potential factors responsible for eyes with low visual outcomes were also investigated.

METHODS

We retrospectively reviewed the clinical records of patients with acute VKH disease who first visited us between 2009 and 2018 and were followed up for > 300 days. Clinical characteristics, treatments, and posttreatment conditions were assessed. Patients were classified into no inflammation worsening (acute-resolved [AR]) and inflammation worsening (chronic-recurrent [CR]) groups based on conditions after 6 months from disease onset.

RESULTS

This study included 60 eyes from 30 patients (mean age: 52.7 years). Patients were treated with methylprednisolone pulse followed by the slow tapering of oral prednisolone; 73% of patients developed AR and 27% CR, and the best-corrected visual acuity (BCVA) was ≥ 1.0 in 83% of eyes at 6 months following the introduction of treatment. Although the total prednisolone dose was higher in patients with CR disease, no significant difference was noted in the final BCVA. Among the patients, five eyes had a final BCVA of ≤ 0.5 due to anisometropic amblyopia, diabetic maculopathy, pre-existing macular hole, epiretinal membrane, and ellipsoid zone loss.

CONCLUSIONS

Patients with acute VKH disease treated with corticosteroid pulse appear to demonstrate good visual outcomes, including patients with CR; the majority of eyes with low visual outcomes have pre-existing conditions that explain the low vision.
