Purpose:
To report 2 cases of Vogt-Koyanagi-Harada disease accompanied by remarkable choroidal folds in the acute stage. The early indicator of recurrence in these 2 cases was the identification of choroidal folds by spectral-domain optical coherence tomography (SD-OCT).
Case reports:
A 68-year-old woman (Case 1) presented with visual loss in both eyes. Funduscopic examination revealed optic disc swelling and serous retinal detachment in both eyes. SD-OCT revealed remarkable choroidal folds and serous retinal detachment. After the initiation of systemic steroid treatment, choroidal folds disappeared rapidly and the amount of serous retinal detachment reduced remarkably. Choroidal folds observed on SD-OCT were the early indicators of recurrence prior to the emergence of serous retinal detachment. A 62-year-old woman (Case 2) presented with bilateral blurred vision and metamorphopsia. SD-OCT showed remarkable choroidal folds and serous retinal detachment in both eyes. After the initiation of systemic steroid treatment, choroidal folds and serous retinal detachment disappeared. At the time of recurrence, choroidal folds were observed by OCT.
Discussion:
During monitoring of Vogt-Koyanagi-Harada disease treatment, choroidal folds could be an early sign of recurrence. When choroidal folds are observed and recognized as an early indicator of recurrence, a prompt increase in steroids can improve the patients' prognosis. Finally, both cases presented here had relatively short axial lengths, and we speculate that a shortened axial length may be a cause of choroidal folds in the acute stage of the disease.
