A Unique Case of Acute Deterioration in Visual Acuity: Vogt-Koyanagi-Harada Disease

Vogt-Koyanagi-Harada (VKH)disease is a chronic autoimmune inflammatorydisorderwithmultisystem involvement particularly involving the eye, skin, ear and brain. Our patient reported in the Ophthalmology OPD, CMH, Lahore, a 41-year-old female patient who presented with decreased visual acuityof 6/9 and 6/18 in her right and left eye respectively with intermittent tinnitus. Aslit lamp examination revealed bilateral paramacular choroiditis, more pronounced in the left eye. Fundoscopy showed the 'sunset glow fundus.' HerOCTshowedslightflattening ofthe foveal contourinthe left eye withgeneralized foveal thinning while the right eye had parafoveal thickening with a foveal lamellar hole. FFAshowed a serous detachment in herleft eye.Adiagnosis of bilateral incomplete Vogt-Koyanagi-Haradasyndrome was made as she tested negative for infectious diseases. She was started on an oral course of steroids initially but after persistent episodic exacerbations ciclosporin 75mg twice daily was started and regular 2 weekly follow-ups were advised. The mainstay of treatment for Vogt–Koyanagi–Harada disease is systemic corticosteroid therapy but the refractory cases get additional immunosuppressants like ciclosporin which was required in our patient as well.Keywords: Autoimmune, Fovea, Visual acuity
