Background/purpose: To examine the diagnostic value of optical coherence tomography (OCT) for the detection of acute Vogt-Koyanagi-Harada (VKH) disease.
Methods: Clinical charts and OCT images were retrospectively reviewed for patients consecutively diagnosed with acute VKH, subacute VKH, multifocal central serous chorioretinopathy (CSCR), and posterior scleritis. All patients underwent OCT, fundus photography, and fluorescein angiography (FA) before treatment. The characteristics of OCT and FA were analyzed and recorded.
Results: The study included 80 eyes with acute VKH, 32 eyes with subacute VKH, 33 eyes with CSCR, and 13 eyes with posterior scleritis. The most common OCT features of VKH disease were hyperreflective dots (70/80; 88%), subretinal membranous structures (64/80; 80%), retinal detachment higher than 450 μm (63/80; 79%), and retinal pigment epithelium (RPE) folds (44/80; 55%). For the detection of VKH disease, sensitivity and specificity were for subretinal membranous structures 80% and 95.6%, respectively, for high retinal detachment 78.8% and 76.1%, respectively, for subretinal hyperreflective dots, 87.5 and 60.9%, respectively, and for RPE folds 55% and 80.4% respectively. Subretinal membranous structures showed the highest positive predictive value (97.3%) and negative predictive value (65.7%) of all OCT assessed features.
Conclusion: OCT-related morphological signs have a relatively high predictive value for the diagnosis of acute VKH.

Atypical presentation of acute retinal necrosis mimicking Vogt-Koyanagi-Harada disease leading to misdiagnosis: a case report.
Front Med (Lausanne)

Acute retinal necrosis (ARN) is a serious, sight-threatening condition characterized by rapidly progressive necrotizing retinitis, most commonly caused by varicella-zoster virus and herpes simplex virus. We report an atypical case of ARN in a 57-year-old immunocompetent male, initially misdiagnosed as Vogt-Koyanagi-Harada (VKH) disease. This case highlights the challenges in the early differential diagnosis of infectious and non-infectious uveitis.

Purpose: This study examined six patients with Vogt-Koyanagi-Harada (VKH) disease using retromode infrared scanning laser ophthalmoscopy (RMI-SLO).
Methods: We conducted a single-center retrospective review of the medical records of six patients diagnosed with VKH disease. The RMI-SLO images were compared to those obtained using color fundus photography, optical coherence tomography (OCT), and dye-based retinal angiography.

Purpose: To investigate the correlation between choroidal biomarkers using enhanced depth imaging optical coherence tomography (EDI-OCT) and indocyanine green angiography (ICGA) scoring for monitoring the activity of Vogt-Koyanagi-Harada (VKH).
Methods: Patients who were not in the acute phase of VKH were recruited. Simultaneous EDI-OCT and ICGA were captured in seven patients only at baseline, in six patients at the 3-month follow-up, and in two patients at both the 6- and 9-month follow-ups.
Article Synopsis
- Vogt-Koyanagi-Harada (VKH) syndrome is an autoimmune condition that affects multiple systems, particularly the eyes and can lead to severe vision loss. Diagnosis involves advanced imaging techniques.
- A study of 100 VKH patients found that most presented with probable VKH syndrome, with common symptoms like defective vision and extraocular effects such as tinnitus and vertigo occurring in 33% of cases.
- Early treatment with corticosteroids was effective, showing improvement in 25% of patients, highlighting the importance of coordination between eye specialists and other healthcare providers for comprehensive care.

Article Synopsis
- Vogt-Koyanagi-Harada syndrome (VKH) is a rare autoimmune disorder that causes severe inflammation in multiple systems, primarily affecting the eyes and leading to symptoms like visual loss and skin changes.
- A 20-year-old male patient experienced rapid vision loss due to granulomatous panuveitis and was treated for complications like cataracts and glaucoma, but only later showed signs of vitiligo and poliosis that confirmed VKH.
- This case emphasizes that VKH can present atypically with glaucoma as the first symptom, highlighting the need for early diagnosis to prevent significant vision loss.
