Purpose: To determine the clinical significance of retinal pigment epithelium (RPE) undulations in the acute stage of Vogt-Koyanagi-Harada disease.

Methods: Retinal pigment epithelium undulations were detected and classified into 3 grades: Grade 1, slight; Grade 2, moderate; and Grade 3, severe undulations, in the enhanced depth imaging optical coherence tomographic images. The relationship between the clinical characteristics and the presence of RPE undulations was investigated.

Results: Among the 61 eyes of 31 patients with Vogt-Koyanagi-Harada disease, 40 eyes had some degree of RPE undulations (Grade 1 = 12, Grade 2 = 15, and Grade 3 = 13). The patients with RPE undulations in both eyes were significantly older at the onset (P = 0.0002). The eyes with RPE undulations were more likely to develop posterior recurrences (P = 0.032) and have worse vision at 12 months (P = 0.043). Multiple regression analysis revealed that RPE undulations were an independent predictor of posterior recurrences (P = 0.009) and poor visual outcomes (P = 0.035).

Conclusion: Retinal pigment epithelium undulations detected by enhanced depth imaging optical coherence tomographic are relatively frequent occurrences at the acute stage of Vogt-Koyanagi-Harada, and their presence is a predictor of posterior recurrences and poor visual outcomes after high-dose steroid therapy.

The retinal pigment epithelium undulations detected by enhanced depth imaging optical coherence tomography were found to be predictive of functional outcomes of Vogt-Koyanagi-Harada disease after high-dose steroid therapy.
