Ultrasound Biomicroscopic Analysis of Transient Shallow Anterior Chamber in Vogt-Koyanagi-Harada Syndrome

Purpose To evaluate the mechanism of formation of the transient shallow anterior chamber in Vogt-Koyanagi-Harada syndrome. Methods Two patients with Vogt-Koyanagi-Harada syndrome with shallow anterior chambers were examined with an ultrasound biomicroscope. Results A ciliochoroidal detachment, which was not obvious on ophthalmoscopic examination, was clearly demonstrated in both patients by ultrasound biomicroscopy. The detachment disappeared after systemic corticosteroid therapy. Conclusion The shallowing of the anterior chamber in two patients with Vogt-Koyanagi-Harada syndrome was caused by suprachoroidal effusion secondary to inflammation of the uvea.
