Brief Summary
Patients with acute onset Vogt-Koyanagi-Harada disease (VKHD) were prospectively included in this study. They were systematically followed with clinical, posterior segment imaging exams and full-field electroretinogram during a minimum 24-month of follow-up. All patients were treated with 3-day methylprednisolone pulse therapy followed by 1mg/day oral prednisone with a slow tapper during a median of 13 months. Non-steroidal immunosuppressive therapy (IMT) was introduced in cases of refractory disease or in cases of prednisone intolerance. Outcome measured by full-field electroretinogram was analyzed and patient was grouped as electroretinogram stable or electroretinogram worsening. Clinical data was analyzed in these two electroretinogram-based groups.

Outcome Measures
Primary Outcomes (3)
Median Values of ERG Scotopic Parameters at 12-month
Full-field electroretinogram (ERG) scotopic parameters were evaluated at 12 -month (scotopic parameters: amplitude of scotopic a and b wave, amplitude of maximum scotopic a and b wave, oscillatory potential).
assessed at 12-month
Median Values of ERG Scotopic Parameters at 24-month
Full-field electroretinogram (ERG) scotopic parameters were evaluated at 24 -month (scotopic parameters: amplitude of scotopic a and b wave, amplitude of maximum scotopic a and b wave, oscillatory potential).
assessed at 24-month
Variation (Worsening or Improvement) Between 24 and 12 Months of ERG Scotopic Parameters Comparing 24 and 12-months
Full-field electroretinogram (ERG) scotopic parameters at 12 and 24 months were compared (scotopic parameters: amplitude of scotopic a and b wave, amplitude of maximum scotopic a and b wave, oscillatory potential). The worsening of the ERG parameters was defined as a value reduction of ≥ 30 % in any these scotopic ERG parameters at month 12 and month 24. We report the change between the (value at month 24/ the value at month 12)\*100.

Study Arms (1)
Corticosteroid monotherapy
OTHERAll patients in the acute phase will be treated with corticosteroid monotherapy, unless presents a contraindication or persistence/ recurrence of inflammation with regressive corticosteroid monotherapy.This is the unique arm of the present study. Treatment protocol includes a three-day course of intravenous methylprednisolone (1000 mg per day) followed by a high dose of oral prednisone (1.0 mg/kg/day) with a slow tapering with dose equal or less than 0.1mg/kg/day after 10 months. The prednisone dose is scheduled to be reduced in a 0.1 mg/kg-step ladder until it reaches 0.3 mg/kg (i.e. for an individual with 60 kg, dose would be 20 mg): from 1 to 0.8 mg/kg every two to three weeks; at 0.7 mg/kg for 4 weeks; at 0.6 mg/kg for two to three weeks; from 0.5 mg/kg every 4 weeks; from 0.3 to 0.15 mg/kg every 6 weeks; and 0.1 mg/kg, 0.075 mg/kg and 0.05 mg/kg for 8 weeks each.
Interventions
Patients will receive corticosteroid monotherapy as a pulsetherapy (1000mg/ day for 3 days) followed by oral corticosteroid.
