Intraocular Gnathostomiasis Manifested as a Unilateral Panuveitis

A 50-year-old Cambodian man presented with unilateral blurred vision that developed shortly after an ischemic stroke. Initial ocular examination showed anterior uveitis, mild retinal vasculopathy with vitreous hemorrhage. Two days later, a live white worm was observed embedded in the iris, migrating through the iris tissue and leaving multiple tracks, causing increased intraocular pressure and secondary glaucoma. A pre-operative diagnosis of intraocular parasitic infection was made, and the worm was surgically extracted. The specimen was identified as Gnathostoma spinigerum, and eventually this was diagnosed as intraocular gnathostomiasis.
