Brief Introduction: Dengue fever is caused by a flavivirus, spread by the Aedes mosquitoes. It can present either in non-severe or severe disease. Dengue is endemic in subtropical and tropical regions, but its geographic reach keeps expanding. Middle and southern Taiwan used to suffer from the epidemic of Dengue fever in hot summer with rain. The precise pathophysiologic mechanisms involved in dengue infection involve a complex interplay between host immune responses, virus, and host genes. There is no specific treatment for ocular dengue. Ophthalmic complications have earlier been known to occur in the form of anterior uveitis, panuveitis, retinitis, sub-hyaloid hemorrhage, retinal hemorrhages, maculopathy, neuororetinitis, optic neuropathy, and corneal epitheliopathy. In this session, we review the general concept, epidemiology of ocular manifestations of Dengue fever as well as case series and risk factor investigations by using a population-based cohort study in Taiwan.
