Intravitreal triamcinolone acetonide for rebound phenomenon after high-dose intravenous steroid treatment in Vogt-Koyanagi-Harada disease

The authors report two cases of rebound phenomenon treated with intravitreal triamcinolone acetonide in Vogt-Koyanagi-Harada (VKH) disease. Patients in the acute phase of VKH disease were treated with high-dose intravenous (IV) methylprednisolone (1 g/day) for 3 days. Serous retinal detachment decreased and visual acuity improved during IV steroid treatment. After switching to oral steroid treatment, choroiditis and visual acuity worsened. An injection of triamcinolone acetonide (4 mg) into the vitreous resulted in gradual resolution of subretinal fluid and improvement of visual acuity. Systemic steroids were tapered to discontinuation without a relapse of inflammation. Adjuvant intravitreal triamcinolone is useful in the management of the rebound phenomenon in VKH disease.
