Abstract
Purpose :
The purpose of this study was to analyze the morphological features of white spots in the peripheral fundus of patients with Sarcoidosis and Vogt-Koyanagi-Harada disease (VKH), which are classified as granulomatous uveitis.
Methods :
Sarcoidosis and VKH patients in Kyushu University Hospital, who had white spots in the periphery of the fundus, were enrolled in the study. Images of the white spots were obtained using Optos® Silverstone, ultra-widefield guided swept source optical coherence tomography (OCT).
We compared the morphological characteristics of those white spots between the two diseases.
Results :
OCT Images of white spots were obtained from 13 patients with Sarcoidosis and 9 patients with VKH. Atrophic lesions were observed in 10 cases of Sarcoidosis and 9 cases of VKH, all of which had retinal pigment epithelial (RPE) defects with no morphological differences between diseases. In both diseases, subretinal elevated lesions were seen in some cases (Sarcoidosis; 5 cases, VKH; 3 cases). Those lesions were Dalen-Fuchs nodule-like elevated lesions with RPE perforation or Sarcoid nodule-like lesions under the RPE without RPE perforation. In contrast, hyperreflective lesions in the retina were found only in Sarcoidosis (7 cases), but not in VKH.
Conclusions :
The site of the white spots in the peripheral fundus varied, suggesting that each disease have a different morphological pattern.
