BackgroundVogt–Koyanagi–Harada (VKH) disease is an autoimmune disorder which affects numerous organs of the body. We report two cases of Optic Nerve Head neovascularisation (NVD) in diagnosed cases of Vogt Koyanagi Harada(VKH) disease.FindingsCase 1: A 40 years female presented with acute loss of vision in both eyes for 10 days. She had multiple serous detachments in both eyes and diagnosed as acute VKH disease. After treatment, she was observed to have NVD later on OCT Angiography(OCTA). Case 2: A 52 years old man presented with history of sudden blackouts in front of left eye since 4 months. He was a case of chronic VKH and NVD was seen clinically and on OCTA. ConclusionThe exact etiopathogenesis of neovascularization in Harada’s disease is unclear. The low grade inflammations acts as a stimulus and can induce disc neovascularization even in the absence of vascular occlusion. ONH vessels appear to be more susceptible to developing NVD than retinal vessels in presence of chronic inflammation. |
