We report a rare case of probable Vogt–Koyanagi–Harada (VKH) syndrome in a 10-year-old child who presented with visual acuity of only perception of light present in both eyes. The anterior segment examination showed cells, flare (4+), fine keratic precipitates over back of the cornea, posterior synechiae, posterior subcapsular cataract, and fundus showing hyperemic disc with blurred margins. B-scan showed shallow retinal detachment and choroidal thickening. Bilateral panuveitis with normal serological and systemic screening was favoring a diagnosis of probable VKH syndrome. The patient was treated with intravenous methylprednisolone followed by oral prednisolone. Visual acuity improved to 6/24 BE.

| Introduction|| |
Vogt–Koyanagi–Harada (VKH) disease is a chronic, bilateral, granulomatous panuveitis and exudative retinal detachment associated with poliosis, vitiligo, alopecia, and central nervous system and auditory signs. The exact cause remains unknown, but evidence suggests that it involves a T-lymphocyte-mediated autoimmune process directed against antigens associated with melanocytes. Several studies demonstrated that tyrosinase family proteins are the antigens associated with VKH syndrome disease., VKH syndrome predominantly occurs in women in their third to fourth decades at the onset of illness. VKH syndrome can occur in pediatric population (about 3%, with an approximate incidence of one case/year), and the prognosis is variable.

A 10-year-old child presented with defective vision in both eyes (BE). There was no history of penetrating intraocular trauma or surgery. On examination, visual acuity was only perception of light present in both eyes. Anterior segment examination showed [Figure 1] cells, flare (4+), fine keratic precipitates over the back of cornea with posterior synechiae, festooned pupil and posterior subcapsular cataract. Fundus examination [Figure 2] showed hazy media with a hyperemic disc with blurred margins. B-scan [Figure 3] showed vitritis, shallow retinal detachment with choroidal thickening. Fundus fluorescein angiography was deferred, considering the age of the child and hazy media. Investigations such as complete blood count, peripheral smear, erythrocyte sedimentation rate, antinuclear antibody, rheumatoid factor, TORCH screening, Mantoux test, high-resolution computed tomography chest, angiotensin-converting enzyme levels, and human leukocyte antigens (HLA) B27 were within normal limits. Bilateral panuveitis with serous shallow retinal detachment with normal serological and systemic screening was favoring a diagnosis of probable VKH syndrome. Hence, intravenous methylprednisolone 20 mg/kg/day for 3 days followed by maintenance dose of oral prednisolone of 1 mg/kg/day was given. After 1 week of steroids, visual acuity improved to 6/60, and spectral domain optical coherence tomography [Figure 4] showed bumpy elevations at the level of retinal pigment epithelium without serous detachment. At the end of 6 weeks, patient was started on oral prednisolone in maintenance dose of 40 mg. After steroid therapy, Visual acuity improved to 6/24 NIG, serous detachment settled, there was a decrease in choroidal thickening and dsappearance of the bumpy elevation in optical coherence tomography. Immunosuppressive, oral cyclosporine 5 mg/kg/day was started with tapering of oral prednisolone to 20 mg/day with periodic review with the pediatrician. After six months of presentation, the child is maintaining visual acuity of 6/24 NIG NIP with posterior subcapsular cataract. Fundus shows sunset glow appearance. Posterior synechiolysis with lensectomy and anterior vitrectomy has to be done for this patient.

| Discussion|| |
VKH syndrome is more common among oriental and dark-skinned individuals. There is a clinical association between HLA DRB1*0405 and HLA DRB1*0410 and VKH. The clinical course of VKH syndrome in children is more aggressive than in adults. The microstructural changes in the retina and the retinal pigment epithelium such as undulations and bumps corresponding to the choroidal striations have been reported., Glaucoma is the most common complication in VKH syndrome because of immune-mediated damage in melanin-bearing cells in the trabecular meshwork., Long-term systemic steroids pose considerable risks in childhood, and they do not adequately control the intraocular inflammation or prevent the ocular complications of VKH syndrome. Immunosuppressants such as methotrexate, cyclosporine, and mycophenolate have to be considered for treating VKH syndrome.
