Dengue-related ocular pathology: A review

Abstract

Dengue is the fastest resurging arthropod-borne viral infection. Over last few decades it has become an important public health problem with considerable increase in its geographical area of spread as well as number of cyclic epidemics. With increasing epidemicity of dengue virus, a surge has been seen in studies reporting dengue-related ocular pathology in the literature. These studies have reported a spectrum of ocular manifestations in dengue patients, ranging from non-specific symptoms to severe vision threatening complications. Considering the range of ocular involvement in dengue patients, we conducted an iterative search of the published literature through Pubmed, Medline and Google Scholar databases. Search terms ocular manifestations, ocular complications, Dengue virus, dengue fever and dengue haemorrhagic fever were used separately as well as in combinations. This review mainly describes the clinical picture, diagnosis and management of dengue-related ocular pathology in addition to brief discussion of epidemiology, clinical features, diagnosis and management of dengue itself.
