A Case of Asymmetrical Vogt-Koyanagi-Harada Disease in a Patient with Ota Nevus Following Laser Treatment

Purpose: To report a case of Vogt-Koyanagi-Harada (VKH) disease exhibiting asymmetric symptoms, predominantly in the affected eye, aside from the bilateral findings noted in indocyanine green angiography (ICG) in a patient who had undergone treatment for nevus of Ota.Case summary: A 33-year-old male presented with decreased visual acuity, ocular pain in the right eye, and a 3-week history of headache. The patient had undergone two laser treatments at 1-month intervals to address a nevus of Ota on the upper and lower eyelids and the maxillary area of the right side. He had no notable medical history. Fundus examination and optical coherence tomography indicated multiple serous retinal detachments. ICG displayed multiple hyperfluorescent spots in both eyes. Given these findings, the patient was diagnosed with VKH disease, predominantly affecting the right eye. Human leukocyte antigen (HLA) testing revealed the presence of the HLA-DRB1*09 and HLA-DQB1*03 (DQ8) alleles. The patient initially received high-dose intravenous steroid therapy, later transitioning to oral steroids. After a month of treatment, the serous retinal detachments had resolved and his vision improved. No signs of recurrence were evident during a 6-month follow-up.Conclusions: VKH disease can manifest asymmetrically, especially in the eye affected after laser treatment for nevus of Ota. Despite potential monocular presentation, it is crucial to assess for binocular involvement through comprehensive examinations.
