Detection of Asymptomatic Choroiditis by Fundus Examination in Vogt-Koyanagi-Harada Disease

To describe the ophthalmoscopic changes of the choroidal vessels in the posterior pole of Vogt-Koyanagi-Harada disease patients whose choroid is thickened due to asymptomatic choroiditis.

Three patients whose choroidal vessels are indistinct or not visible in the posterior pole by ophthalmoscopy were examined by fundus photography and enhanced-depth imaging optical coherence tomography (EDI-OCT).

They did not complain of vision problems, and visual acuity was good. Serous retinal detachment was not observed by ophthalmoscopy or by OCT. However, choroidal thickening was observed in the EDI-OCT, while choroidal vessels became blurred or invisible on ophthalmoscopy. After steroid therapy, choroidal thickness decreased to normal levels and the small and large choroidal vessels previously indiscernible became visible by ophthalmoscopy and fundus photography.

Asymptomatic choroiditis not accompanied by serous retinal detachment can be detected and assessed by observing the changes in the choroidal vessels by ophthalmoscopy and fundus photography.
