Abstract: Dengue fever is an endemic condition of tropical areas because of arboviruses. Ocular manifestations are rare and mainly include posterior segment findings. We report a case of cysticercosis causing orbital cellulitis and panophthalmitis in dengue fever. The presentation was acute in onset, with rapid progression of the disease, leading to blindness. The diagnosis of cysticercosis was established on imaging, positive anticysticercal antibodies, coexisting brain parenchymal calcification, and therapeutic response to anticysticercal therapy. The location of the cyst in relation to medial rectus and sclera and possible immune dysfunction caused by dengue fever were responsible for the fulminant course causing intense inflammation within the globe and orbit.
