RESUMEN

Vogt-Koyanagi-Harada (VKH) disease is a multisystem inflammatory disease that usually presents with bilateral panuveitis. Unilateral manifestations of VKH, albeit rare, have been described. Choroidal neovascularization may occur as a complication during the disease. Reactivation of uveitis may also occur during treatment. A patient with unilateral features of VKH disease presented with two distinct types of choroidal neovascular membranes and two episodes of reactivation of posterior uveitis. He underwent treatment with a combination of systemic steroids/immunosuppressive agents, intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents, and dexamethasone implants with good clinical response.  Patients with VKH disease need to be diagnosed early, treated adequately with a combination of systemic and ocular medication, and followed up diligently for any complication that may arise, to optimize visual acuity.

RESUMEN

We have recently described an OCT sign in two patients (one with Vogt-Koyanagi-Harada (VKH) and the other with Sympathetic Ophthalmia) consisting of hyperreflectivity of the outer nuclear layer (HONL) that subsequently evolved into outer retina atrophy and associated with poor functional outcomes. Ali et al. have published a comment on our letter regarding HONL. They have evaluated it in 90 eyes of VKH patients. It was observed in 37 eyes (41.1%) and no associations were found between HONL and structural outcomes or final visual acuity, and no cases of retinal atrophy were described. In the present author's reply, we point out two reasons for these contradictory observations. First, we considered HONL a full thickness hyperreflectivity of the outer nuclear layer, whereas they included cases with partial thickness hyperreflectivity, hence probably milder cases. Second: they have assessed visual function by means of visual acuity, so cases with extrafoveal involvement whose functional deficiency might only be measured by other tests (i.e. visual field) might have been missed.

RESUMEN

Vogt-Koyanagi-Harada disease (VKH) is a neurological disorder that impacts vision and hearing by causing the immune system to attack melanocytes. Symptoms of the condition include flu-like symptoms, eye pain, headache, and dizziness, which may progress to vitiligo and hearing impairment. The diagnostic criteria include ocular involvement, generalized choroiditis, tinnitus, meningitis, and skin depigmentation. The treatment includes corticosteroids and immunosuppressive drugs. VKH is believed to be an autoimmune condition, possibly triggered by hereditary factors and cross-reactivity with cytomegalovirus. VKH is common in East Asia and India and has a genetic link to certain alleles. Inflammation generated by Th1 in melanocytes results in the production of granulomas. An analysis of a 48-year-old female with VKH disease revealed symptoms of anterior uveitis and subsequent glaucoma. The treatment involved the administration of systemic steroids and intratympanic steroid injections. Biochemical indicators showed signs of inflammation. Timely identification and therapy are essential for managing VKH. Further research is necessary to enhance outcomes for patients with VKH disease.

RESUMEN

PURPOSE: The choroidal thickening and serous retinal detachments that characterize Vogt-Koyanagi-Harada (VKH) disease can be imaged in detail using spectral domain optical coherence tomography (SD-OCT). Whether specific qualitative and quantitative SD-OCT features at presentation were associated with visual outcomes in a randomized controlled trial comparing methotrexate to mycophenolate for steroid-sparing control of uveitis were evaluated. METHODS: An exploratory subanalysis of data from the FAST trial in which SD-OCT images from VKH participants were analyzed for presence/absence of bacillary detachments, retinal pigment epithelium (RPE) folds, and internal limiting membrane (ILM) fluctuations was performed. A modified RPE undulation index was calculated to provide a quantifiable surrogate marker for choroidal folds. RESULTS: SD-OCT images were available from 158 eyes with VKH. At baseline, bacillary detachments were present in 23.5% of eyes, RPE folds in 22.8% of eyes, and ILM fluctuations in 35.2% of eyes. For each 0.1 unit increase in modified RPE undulation index, there was an associated 0.13 increase in mean logMAR BSCVA at baseline. None of the SD-OCT features were associated with BSCVA at the 6-month primary endpoint. Indeed, mean final BSCVA was similar in those with and without the SD-OCT features of interest at baseline, and was between 0.1 and 0.2 logMAR (Snellen visual acuity 20/25 to 20/30). CONCLUSIONS: While eyes with VKH may present with a variety of SD-OCT imaging pathology prior to starting immunosuppression with methotrexate or mycophenolate mofetil, final visual outcome in our study was excellent. With appropriate immunosuppression, good visual outcomes are possible in VKH.ClinicalTrials.gov Identifier NCT01829295Date of Registration: April 11, 2013.

RESUMEN

A middle-aged hypertensive female presented with headaches, tinnitus, and blurred vision for two weeks. Clinical examination revealed mild vitritis and bilateral multifocal exudative detachments at the posterior pole, together with peripheral vascular cuffing and peri-phlebitis. Laboratory testing pointed towards isolated presumed intraocular tuberculosis (IOTB) as the probable cause. However, the patient strongly responded to high-dose intravenous and tapered oral corticosteroids, leading to complete resolution of detachments within 10 days of therapy initiation. Anti-tubercular therapy (ATT) was begun after one week of presentation, and no recurrence of symptoms was noted for the next 18 months. A case of Vogt-Koyanagi-Harada (VKH) disease-like presentation occurred after a probable previous subclinical episode(s) of presumed IOTB, resulting in sclerosed vessels in the retinal periphery.

RESUMEN

Vogt-Koyanagi-Harada syndrome (VKH) is an uncommon multi-system autoimmune inflammatory disorder characterized by bilateral granulomatous panuveitis with serous retinal detachment accompanied by neurological, auditory, and cutaneous manifestations like headache, hearing loss, vitiligo, and poliosis. It has a female preponderance, usually in middle age. We report the case of a 20-year-old male who presented to us with rapidly progressive visual loss accompanying granular panuveitis, complicated cataract, and a mixed mechanism neovascular glaucoma with acute angle closure. He was treated for IOP control and underwent aggressive immunosuppression and, later, bilateral laser iridotomies. It wasn't until one month after the initial presentation that he presented with vitiligo and poliosis of the eyebrows and eyelashes, clinching the diagnosis of VKH syndrome. This case highlights the diagnostic challenge faced due to acute neovascular glaucoma being the initial presenting feature of VKH; hitherto not documented before, although acute angle closure glaucoma or crisis has occasionally been reported at presentation; the classical VKH presentation being an acute posterior segment uveitis or less commonly, a chronic, recurrent panuveitis presenting with/ without complications. This case underlines the importance of considering VKH syndrome in a patient with bilateral granulomatous panuveitis, as dermatological involvement can emerge later in the disease course, by which time vision might have already been compromised significantly.

RESUMEN

TOPIC: To determine the cumulative incidence and features of glaucoma in patients with Vogt-Koyanagi-Harada (VKH) syndrome compared with nonglaucoma patients. CLINICAL RELEVANCE: Knowing the exact burden of secondary glaucoma in VKH could guide its screening and management in clinical practice as a part of the regular follow-up for patients with VKH. METHODS: The review protocol was preregistered on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PROSPERO) [CRD42023462794]. PubMed, Scopus, Web of Science, EBSCOhost, and Google Scholar were searched for studies reporting the cumulative incidence and features of glaucoma presentation in VKH. A manual search was also conducted to supplement the primary search. Subgroup analyses based on glaucoma type, VKH stage, and patients' age were conducted. All analyses were conducted using STATA. Fixed- and random-effects models were selected according to the observed heterogeneity. Studies' methodological quality was determined using the National Institutes of Health tool. RESULTS: The analysis of 7084 eyes revealed a progressive increase in the cumulative incidence of secondary glaucoma over time. The cumulative incidence was lowest at VKH onset (7%) and highest at 15 years (26%). Open-angle (12%; 95% confidence interval [CI]: 9%-14%) is more common than angle-closure glaucoma (7%; 95% CI: 3%-13%). Glaucoma cumulative incidence is highest in the chronic recurrent stage of VKH (33%; 95% CI: 12%-59%) and among children < 18 years of age (26%; 95% CI: 16%-37%). Features associated with glaucoma occurrence in VKH showed comparable rates with nonglaucoma cases. However, a meta-analysis to determine risk factors of glaucoma development in VKH was not feasible secondary to the lack of adjusted risk measures in included studies. Studies' quality was questionable in 5 studies. The certainty of evidence was moderate-to-high. CONCLUSION: The cumulative incidence of glaucoma increases throughout VKH's course, with a higher tendency in children, chronic recurrent stages, and long-term follow-up. Future research should focus on examining risk factors of glaucoma development in VKH through adjusted multivariable regression models.

RESUMEN

Introduction: We aimed to describe a clinical presentation of central serous retinopathy that poses a diagnostic and management dilemma. Case Presentation: A 30-year-old male patient presented with bilateral vision loss and multifocal serous retinal detachments involving the posterior pole of both eyes. Optical coherence tomography revealed prominent bilateral bacillary layer detachments. The patient complained of recent headaches and tinnitus. However, the clinical exam did not reveal overt inflammation and the patient admitted to being under significant stress. The clinical presentation raised concerns for both central serous retinopathy (CSR) and Vogt-Koyanagi-Harada (VKH). Additional findings, including white fundus spots and focal areas of retinal vascular leakage, were seen in our patient. We highlight these because, while they have been described in CSR, they are not commonly discussed and could add to the diagnostic dilemma. After a conservative approach that avoided steroids, our patient showed marked improvement over the following month, supporting a diagnosis of CSR. Conclusion: CSR can mimic VKH disease. A high level of suspicion is needed to avoid instituting steroid therapy that could induce a severe iatrogenic exacerbation of the disease.

RESUMEN

This review covers the utility of electrophysiological studies relevant to inflammatory diseases of the retina in conditions such as acute posterior multifocal placoid pigment epitheliopathy, acute zonal occult outer retinopathy, Adamantiades-Behçet disease, autoimmune retinopathy and neuro-retinopathy, birdshot chorioretinopathy, multiple evanescent white dot syndrome, and Vogt-Koyanagi-Harada disease. Electrophysiological studies can help with the diagnosis, prognostication, evaluation of treatment effects, and follow-up for these conditions.

RESUMEN

PURPOSE: To characterize the dynamic changes of fundus in Vogt-Koyanagi-Harada (VKH) disease through enhanced spectral-domain optical coherence tomography (EDI-OCT) and explore the predictors of visual prognosis. METHODS: In this retrospective cohort study, a total of 2152 VKH patients referred to our uveitis center from January 2013 to April 2022 were screened; 151 new-onset VKH patients (299 eyes) and 82 healthy controls (164 eyes) were included. The manifestations of fundus at baseline, 1 month, 3 months, and 12 months after treatment were analysed and their relevance to visual prognosis were evaluated. RESULTS: After retinal detachment (RD) (97.3%) and optic disc swelling (100%) presented at baseline, retinal reattachment (81.6%) and the granular hyperreflective depositions at the retinal pigment epithelium (RPE) (61.5%) were observed at month 1. The RPE and ellipsoid zone rearrangement accompanying interdigitation zone attenuation (57.9%) was noted finally. Choroidal thickness of patients was higher than that in the controls at baseline and month 1 (both P < 0.001). Best-corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution [logMAR]) (P < 0.001; OR, 4.01), subretinal fibrinoid exudate (P < 0.001; OR, 3.9) and RPE folds (p = 0.001; OR, 2.39) at baseline, and the RD at month 1 (P < 0.001; OR, 3.42) were associated with visual prognosis. CONCLUSIONS: New-onset VKH patients after treatment exhibited dynamic changes in the fundus especially the outer retina during a 12-month period. The BCVA, subretinal fibrinoid exudate, and RPE folds at baseline, and RD at month May 1, serve as predictors of visual prognosis.

RESUMEN

BACKGROUND: This study explores prognostic factors influencing Vogt-Koyanagi-Harada (VKH) disease and observes the efficacy and safety of Adalimumab (ADA) in treating recurrence in Vogt-Koyanagi-Harada (VKH) patients. METHODS: A retrospective study was conducted on all patients diagnosed with VKH disease at Beijing Tongren Hospital between 2020 and 2023. Clinical data included initial and final visual acuity, age, gender, ocular complications, treatment modalities, disease duration, and recurrence frequency. RESULTS: A total of 62 VKH patients were included, comprising 34 in the acute-resolved group and 28 in the chronic-recurrent group. The mean age of patients in the acute-resolved group was 38.29 ± 15.46 years, while the mean age of chronic-recurrent group had a 49.00 ± 16.43 years. Initial best-corrected visual acuity (BCVA) examination at the first visit showed an average BCVA of 0.64 ± 0.29 logMAR in the acute-resolved group and 1.38 ± 0.54 logMAR in the chronic-recurrent group (p = 0.002). During follow-up, ocular complications were observed in 29.4% of the acute-resolved group patients and 41.7% of the chronic-recurrent group patients (P = 0.006). "Sunset glow fundus" was observed in 23.5% of the acute-resolved group and 64.3% of the chronic-recurrent group patients (P = 0.001). Poor initial BCVA (P = 0.046) and the occurrence of "sunset glow fundus" (P = 0.040) were significantly associated with progression to the chronic recurrent phase. Logistic regression analysis revealed that older age at onset (P = 0.042) and the occurrence of "sunset glow fundus" (P = 0.037) were significant predictors for progression to the chronic recurrent phase. ADA significantly reduced anterior chamber inflammatory cells (P = 0.000) and vitreous cavity inflammatory cells (P = 0.001) in the chronic-recurrent group, and markedly decreased the recurrence rate in VKH patients (P = 0.009). CONCLUSION: In comparison to acute-resolved patients, chronic-recurrent patients exhibited poorer initial BCVA and a significantly increased incidence of "sunset glow fundus." Older age at onset and the occurrence of "sunset glow fundus" at diagnosis are crucial predictive factors for VKH patients progressing to the chronic recurrent phase. ADA effectively alleviates refractory VKH disease and is generally well-tolerated.

RESUMEN

BACKGROUND: Several immune checkpoint inhibitors (ICIs) have been linked to the occurrence of Vogt-Koyanagi-Harada disease (VKHD)-like uveitis. Among the ICIs, there has been no report of immune-related adverse events (irAEs) caused by a new programmed death protein-1(PD-1) monoclonal antibody (Toripalimab). CASE PRESENTATION: This paper presents a case of VKHD-like uveitis that arose following Toripalimab therapy for urothelial cancer of the bladder, and the patient experienced symptoms 10 days after the final dosage of 20 months of medication treatment. This patient with bladder uroepithelial carcinoma had severe binocular acute panuveitis with exudative retinal detachment after receiving Toripalimab therapy. Binocular VKHD-like uveitis was suggested as a diagnosis. Both eyes recovered after discontinuing immune checkpoint inhibitors and local and systemic corticosteroid treatment. CONCLUSIONS: This report suggests that VKHD-like uveitis can also occur in patients receiving novel PD-1 antibodies and the importance of paying attention to eye complications in patients receiving treatment over a long period.

RESUMEN

To determine the disease prevalence rate and clinical characteristics of Vogt-Koyanagi-Harada (VKH) disease among new patients before and after the declaration of a state of emergency (April 7, 2020) in Japan. New patients and patients with newly diagnosed VKH disease were categorized into "Before" and "After" groups based on the initial visit. The prevalence rate, sex ratio, and age of patients newly diagnosed with VKH were compared between the groups. Best-corrected visual acuity (BCVA) and recurrence rates were compared among 59 patients observed for > 12 months after receiving pulse steroid therapy. For reference, we also examined the prevalence rate of patients newly diagnosed with acute angle closure (AAC) in the Before and After groups. The prevalence rates of VKH disease among newly diagnosed patients (P < 0.05) or patients with AAC (P < 0.001) were significantly higher in the After group. No significant differences in sex ratio or age of VKH disease were observed in both groups. BCVA and recurrence rates showed no significant differences. The COVID-19 pandemic increased the prevalence of VKH disease among new patients compared with that of AAC. However, the clinical features of VKH disease were unlikely affected by the COVID-19 pandemic.

RESUMEN

PURPOSE: To compare the 26-week cost-effectiveness of adalimumab-corticosteroids (ADA-CS) and cyclosporine-corticosteroids (CSA-CS) for Vogt-Koyanagi-Harada (VKH). METHODS: A preplanned cost-effectiveness analysis based on the per-protocol population of a randomized-controlled trial. VKH subjects were randomized to receive either cyclosporine (100-200 mg daily) combined with corticosteroids or adalimumab (40 mg twice monthly) combined with corticosteroids. The primary outcome of this cost-effectiveness study was the incremental cost-effectiveness ratio (ICER). Costs and quality-adjusted life-years (QALYs) data were calculated by the medical records and health utility, respectively. Subgroup (early and late-phase VKH) analysis and sensitivity analyses were performed. RESULTS: The ICER at 26 weeks was $62,425/QALY for the total participants. Compared to the CSA-CS group, costs in the ADA-CS group were more expensive (mean difference [ΔA-C]: $2,497) with more gains in QALYs (mean difference [ΔA-C]: 0.04). The probability of ADA-CS being cost-effective was 0.17 and 0.41 at willingness to pay (WTP) thresholds of $12,000/QALY and $36,000/QALY, respectively. Subgroup analysis and sensitivity analyses showed consistent findings with the primary analysis. CONCLUSIONS: Regardless of early or late-phase VKH, the CSA-CS strategy may be recommended as the preferred initial choice for the majority of VKH.

RESUMEN

PURPOSE: To evaluate the association between quantitative parameters derived from volume analysis of optical coherence tomography (OCT) data and disease worsening in Vogt-Koyanagi-Harada disease (VKHD) and sympathetic ophthalmia (SO). METHODS: This retrospective study, conducted at Osaka University Hospital, employed swept-source OCT scans from patients diagnosed with VKHD or SO between October 2012 and January 2021. The choroidal vessel structure was segmented and visualized in three dimensions, generating quantitative vessel volume maps. Region-specific choroidal vessel volume (CVV), choroidal volume (CV), and vessel index (VI) were scrutinized for their potential correlation with disease severity. RESULTS: Thirty-five eyes of 18 VKHD and 2 SO patient (8 females, 10 males) were evaluated. OCT-derived CVV maps revealed regional CV alterations in VKHD and SO patients. Two parameters, i.e. CV at 3- and 6-month follow-ups (p = 0.044, p = 0.040, respectively, with area under the ROC curve of 0.70) and CVV at 6 months (p = 0.046, area under the ROC curve of 0.71), were significantly higher in recurrent VKHD and SO compared to effectively treated cases. CONCLUSIONS: The volume analysis of OCT images facilitates a three-dimensional visualization of choroidal alterations, which may serve as a reflection of disease severity in VKHD and SO patients. Furthermore, noninvasive initial CVV or CV measurements may serve as potential biomarkers for predicting disease recurrence in VKHD and SO.

RESUMEN

PURPOSE: We aimed to evaluate adalimumab efficacy in patients with initial-onset or recurrent Vogt-Koyanagi-Harada (VKH) syndrome. METHODS: A retrospective clinical study was performed to examine the therapeutic effect of adalimumab in 22 VKH patients,16 with initial-onset and six with recurrent VKH. Another 22 patients with initial-onset VKH who did not receive adalimumab were included as controls. The main observational parameters included the central macular thickness (CMT), subfoveal choroidal thickness (SCT), best-corrected visual acuity (BCVA), anterior chamber cell grade (ACC), glucocorticoid dose (GCD), and the development of sunset glow fundus. MRNA sequencing was used to profile the tumor necrosis factor (TNF)-α pathway in peripheral blood mononuclear cells obtained from nine patients with initial-onset VKH disease, six patients with recurrent VKH, and eight healthy controls. RESULTS: In the initial-onset group, adalimumab therapy significantly improved the BCVA, CMT, SCT, and ACC. Furthermore, adalimumab significantly decreased GCD in patients with initial-onset. In patients with recurrent VKH, the SCT significantly improved after adalimumab treatment, but no significant changes in BCVA, CMT, and ACC were observed. All six patients experienced relapse during follow-up. The TNF-α pathway exhibited a significant increase in initial-onset VKH when compared with that in both healthy controls and recurrent patients. Conversely, it was suppressed in recurrent VKH when compared with that in the initial-onset or healthy control groups. CONCLUSIONS: In patients with initial-onset VKH, adalimumab effectively reduces glucocorticoid dependence. However, adalimumab may not be effective for preventing relapse or providing long-term inflammation relief in patients with recurrent VKH.

RESUMEN

Objective: This study aimed to compare enhanced depth imaging optical coherence tomography (EDI-OCT) features of exudative retinal detachment (ERD) type and optic disc (OD) swelling type Vogt-Koyanagi-Harada (VKH) disease. Methods: Hospitalized VKH patients were retrospectively reviewed and classified into the ERD type and the OD swelling type. The EDI-OCT features were then analyzed. Results: The study included 32 ERD type and 15 OD swelling type VKH patients at the acute uveitis stage. The interval between the onset of ocular symptoms and the start of treatment in OD swelling type VKH disease was significantly longer compared to the ERD type (p < 0.001). A fuzzy or lost pattern of the choroidal vasculature was observed in 100% of VKH patients of both types. Moreover, high frequencies (greater than or equal to 50%) of fluctuations in the internal limiting membrane, interdigitation zone disruption, ERD, retinal pigment epithelium (RPE) folds, and ellipsoid zone disruption were observed in both types. Patients with OD swelling type VKH disease exhibited higher frequencies of OD swelling and hyperreflective substances above the RPE (p < 0.001 and p = 0.003, respectively), with lower frequencies of ERD and bacillary layer detachment (p = 0.012 and p < 0.001, respectively). At the convalescence stage, changes in the EDI-OCT images of 10 ERD type and 5 OD swelling type VKH patients were analyzed. The frequencies of the OCT features decreased with similar trends in both types of VKH disease. Conclusion: Although ERD type and OD swelling type VKH disease have their own unique characteristics, they share common EDI-OCT features. The Fuzzy or lost pattern of the choroidal vasculature that indicates choroidal inflammation may serve as a diagnostic aid for VKH disease, especially for the OD swelling type and the early-stage ERD type.

RESUMEN

Vogt-Koyanagi-Harada (VKH) disease is an idiopathic immune-related sickness that affects multiple systems and melanocytes in organs such as the uvea, ear, and meninges. The primary cause of activity is cellular immunological responses. Vogt-Koyanagi disease is identified primarily by skin abnormalities and anterior uveitis. Harada's illness is distinguished by neurological symptoms and exudative retinal detachments, which are associated with the HLA-DR4 and HLA-DRw53 genes. Pigmented races, such as Hispanics and Native Americans, are more likely to have VKH disease. Clinical features are blurred vision, floaters, alopecia, vitiligo, diffuse choroidal inflammation with disc edema, and exudative retinal detachment. Differential diagnoses include posterior scleritis, uveal effusion syndrome, central serous chorioretinopathy, and sympathetic ophthalmitis. The investigations used are optical coherence tomography (OCT), fundus fluorescein angiography (FA), and B-scan ultrasonography (USG). Treatment is done by using systemic steroids, cycloplegics, and immunosuppressants.

RESUMEN

BACKGROUND: Bilateral retinal detachment and choroidal detachment in a patient are rare occurrences. The presence of bilateral diabetic retinopathy (DR) in such a case is even rarer and complicates the condition. CASE PRESENTATION: In this study, we document a case of unconventional VKH. Manifestations in this patient included intense peripheral retinal detachment and choroidal detachment, along with vitreous opacities akin to cotton wool spots, concurrent with DR. The diagnosis was considered as probable VKH with DR. Treatment according to VKH protocols, including high-dose corticosteroids, yielded positive results. CONCLUSIONS: VKH can co-occurrence with DR. VKH manifestations vary, and early, aggressive, and long-term treatment is essential. The complexity of treatment increases with concurrent DR, necessitating the use of immunosuppressants.

RESUMEN

A 45-year-old male with Vogt-Koyanagi-Harada (VKH) syndrome presented with vision loss in his right eye after discontinuing treatment during the COVID-19 pandemic. He was found to have bullous retinal detachment (RD) in the right eye and was started on subcutaneous adalimumab with oral corticosteroid following three doses of pulse corticosteroid. But when RD did not resolve after 4 months of treatment and ultrasound B scan showed bullous RD with retino-retinal adhesion, he was planned for surgical intervention. During surgery, there was retino-retinal adhesions due to long-standing "kissing exudative RD", causing non-settling exudative RD. Following surgery, the vision improved to 2/60, with attached retina. The patient has been under follow-up with us for the last one year now and developed no recurrence of RD till now. This case emphasises the significance of retinoretinal adhesion in long-standing bullous RD that does not respond to conventional aggressive medical therapy.
