A case of probable Vogt-Koyanagi-Harada disease in a 3-year-old girl

Clinical Characteristics, Recurrences, and Complications in the Mexican Pediatric Patients with Vogt-Koyanagi-Harada Disease

PURPOSE

To analyze the clinical characteristics, number of recurrences, and complications in the Mexican pediatric patients with Vogt-Koyanagi-Harada (VKH) disease.

METHODS

A retrospective review of pediatric patients aged 16 years and under, diagnosed with VKH, was conducted from January 1988 to February 2023 at Asociación para Evitar la Ceguera en México I.A.P.

RESULTS

Thirty-one patients (n = 62 eyes), with a diagnosis of VKH were identified, with a mean age of 12.06   ±   3.57 years. Follow-up was 7.22   ±   6.85 years. At initial presentation, the best-corrected visual acuity (BCVA) was 1.31   ±   0.94 LogMAR (Snellen 20/400) and final 0.5   ±   0.93 LogMAR (Snellen 20/60) (p = 0.001). The most common clinical findings in the uveitic stage were anterior chamber inflammation (70%) and serous retinal detachment (72%). The treatment approach involved a combination of oral steroids, intravenous steroids, and immunomodulatory agents. Despite the initial visual impairment, most patients achieved disease remission. However, 41.93% of the patients experienced at least one recurrence during follow-up. The most frequent complications were sunset-glow fundus 74.19% (n = 46 eyes), and glaucoma 27.41% (n = 17 eyes).

CONCLUSION

VKH disease in the Mexican pediatric patients has proved to be a challenge in management due to its aggressive course. Timely diagnosis and treatment with steroid therapy associated with a systemic immunomodulatory are essential to reduce recurrences, and complications and thus have a better visual prognosis.

VKH with APECED in a Two-Year-Old Child: A Rare Concomitant Diagnosis in an Unprecedented Age

PURPOSE

To present a case of Vogt Koyanagi Harada (VKH) associated with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) in a two-year-old.

CASE PRESENTATION

A two-year-old type 1 diabetic with hypothyroidism presented with impaired fixation. Ocular examination revealed right vitritis, choroiditis, a hyperemic disc, and an area of exudative detachment. At the same time, there was no fundus view in the left eye, and ultrasonographic assessment revealed vitritis and a thickened choroid. Patient developed sunset glow fundus with alopecia, poliosis and vitiligo and a diagnosis of complete VKH with APECED was made.

CONCLUSION

APECED is a rare endocrine disorder and has been reported to be associated with VKH twice. Likewise, VKH is commonly present in much older patients; this is the first time ever to be diagnosed in a two-year-old child.

Vogt-Koyanagi-Harada Disease in Pre-school Children

PURPOSE

To report the management and outcome of VKH disease in a 4-year-old boy with a review of literature on VKH in preschool children (3 to 5 years).

METHOD

Retrospective chart and literature review.

RESULT

A 4-year-old boy presented with visual acuity of light perception in both eyes with panuveitis, secondary cataracts and intraocular pressure (IOP) of ≥40 mmHg in both eyes. He was started on oral corticosteroid, immunosuppressive and underwent glaucoma filtering surgery and lensectomy with vitrectomy after adequate control of intraocular inflammation. Over time his IOP was again uncontrolled even with maximum anti-glaucoma medications, and he underwent Ahmed glaucoma valve (AGV) implantation, and he gained a visual acuity of 20/60 in both eyes with aphakic correction at the last visit.

CONCLUSION

Paediatric VKH follows an aggressive disease phase and requires a comprehensive multispeciality management approach.

Vogt-Koyanagi-Harada Disease: A Narrative Review

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.

Vogt-Koyanagi-Harada Disease: The Clinical Spectrum and Management of Case Series in a Tertiary Eye Centre in Northern Part Of Malaysia

AIMS

We present the clinical spectrum, the initial clinical presentation with management trends in treating 14 Vogt-Koyanagi-Harada (VKH) disease cases in a tertiary center in the Northern part of Malaysia.

CASE SERIES

There were 14 cases of Vogt-Koyanagi-Harada (VKH) disease retrospectively reviewed over five years (from 2015 to 2020). The mean age at presentation was 37.7 years (range 21-64 years), with female predominance (85.7%). All cases presented with acute uveitic stage and bilateral eye involvement. Of them, 11 (78.6%) were probable VKH, and three (21.4%) were incomplete VKH. All patients attended with acute panuveitis at first presentation. The main posterior segment involvement was disc edema in 57.1% (16 out of 28 eyes) and exudative retinal detachment (ERD) in 35.7% (10 out of 28 eyes). Most of them presented with blindness (3/60 and worse) and moderate visual impair- ment (6/18-6/60); 35.71% each, followed by mild visual impairment (6/12-6/18), and severe visual impairment (6/60-3/60); 7.1% each. Ten patients (71.4%) required combination second-line immunomodulatory treatment during subsequent visits, and only four patients (28.6%) responded well to corticosteroid therapy. Most of the cases achieved no visual impairment (64.3%), followed by mild visual impairment (21.4%) and moderate visual impairment (14.3%), and none were severe or blind at the end of follow-up.

CONCLUSION

VKH is a potentially blinding illness if there is inadequate control of the disease in the acute stage. Most of our patients achieved good visual outcomes with early immunomodulatory treatment and systemic corticosteroids.

Vogt-Koyanagi-Harada Syndrome (VKHS): First Two Cases Reported in Pediatric Age Group in Oman

The Vogt-Koyanagi-Harada syndrome (VKHS) is a unique form of granulomatous autoimmune disease that mostly impacts the pigmented tissues of the body. The main feature is bilateral granulomatous panuveitis, which is detected on ophthalmologic examination, along with additional systemic signs such as vitiligo, white hair, neurological involvement, or hearing loss. This study aims to report two cases of Vogt-Koyanagi-Harada syndrome presented in the children age group, which is unusual and very rare, to improve recognition of this disease to avoid complications and delay referral.

Sympathetic ophthalmia in an 85-year-old female and a 90-year-old male after a non-complicated cataract surgery: a case report

Here, two cases involving the oldest reported patients with sympathetic ophthalmia (SO) after non-complicated cataract surgery, are reported. The first case was an 85-year-old female with bilateral decreased vision and headache. The best-corrected visual acuity (BCVA) was 0.8 in the right eye and 1.0 in the left eye at the initial visit. Pseudophakia and choroidal detachments were observed in both eyes, and retinal pigment epithelium undulation was observed by optical coherence tomography. The second case was a 90-year-old male with bilateral optic disc oedema. The BCVA was 0.09 in the right eye and 0.3 in the left eye with pseudophakic eyes. Optic disc oedema and choroidal thickening were observed in both eyes. Both patients were diagnosed with SO, and corticosteroid pulse treatments were started. The BCVA of the first case improved to 0.9 in the right eye and 1.2 in the left eye, while that of the second case reached 0.3 in the right eye and 0.6 in the left eye. No recurrence was observed in either case at 12 months after the initial visit. Both elderly patients with SO were successfully treated.

Multimodal imaging in pediatric uveitis

Pediatric uveitis accounts for up to 10% of all uveitis cases, so special attention must be paid to ensure early diagnosis as well as treatment and follow-up of these young patients in order to decrease the risk of possible ocular complications and consequently vision loss. Multimodal imaging has been an effective and important adjunct in the diagnoses and management of uveitis, especially in children. Reviewed here are the currently utilized modalities, advances, as well as their applications in juvenile idiopathic arthritis-associated uveitis, pars planitis, retinal vasculitis, tubulointerstitial nephritis and uveitis syndrome, Behçet disease, Blau syndrome, and Vogt-Koyanagi-Harada syndrome.

Clinical and therapeutic features of pediatric Vogt-Koyanagi-Harada disease

PURPOSE

To analyze clinical, therapeutic and prognostic features of pediatric Vogt-Koyanagi-Harada (VKH) disease.

MATERIAL AND METHODS

This retrospective study included 16 eyes of 8 children diagnosed with VKH disease followed at a teaching hospital over a 10 year period. Diagnosis was based on the revised criteria of VKH disease. All data were analyzed using SPSS® software.

RESULTS

There were 62.5% girls and 37.5% boys. The mean age (years) was 14.6±4.4. The mean follow-up (months) was 38.7±28.7. The mean initial visual acuity (VA) (LogMAR) was 1.4 with 68.8% of eyes presenting with severe visual loss at admission. The median time (days) required for resorption of the serous retinal detachment was 10 [8.25-25]. Extraocular signs were present in 62.5% of cases. The mean time until initiation of treatment was 25.6 days. 62.5% of patients received corticosteroids alone, and 37.5% of patients received a combination of corticosteroids and immunosuppressive therapy. Final VA was 0.4 [0.1-2.3]. In our study, the time until consultation, low initial VA and recurrences were statistically associated with severe visual loss (P≤0.05).

CONCLUSION

Life expectancy in pediatric cases of VKH disease justifies the early initiation of immunosuppressive treatment or even biological therapy to achieve better steroid sparing and preserve visual function.

Vogt-Koyanagi-Harada (VKH) syndrome: A new perspective for healthcare professionals

Vogt-Koyanagi-Harada syndrome (VKH syndrome) is a rare granulomatous inflammatory disease that affects the melanin pigment producing melanocytes and mainly affects the pigmented structures such as eyes, ear, skin, meninges, and hair. VKT is an autoimmune disorder, which is mainly a T CD4+ Th1 lymphocyte-mediated aggression to melanocytes, in individuals with a genetic predisposition, in particular, the presence of HLA-DRB1 * 0405 allele. Melanin usually gives color to skin, hair, and eyes. Melanin is also found in the retina, where it plays a role in normal vision. This disease mainly leads to vision and hearing disturbances, followed by dermal problems. The most common symptoms include vitiligo, headaches, hair loss (alopecia), and hearing loss. This article describes the various signs and symptoms of VKH disease and its pathogenesis.
