BACKGROUND: Though rickettsiosis is common in India, there is paucity of @entity2479 ( @entity2479 ) reports from India. Moreover, rickettsial sub-types and their association with @entity2479 have not been studied. We are reporting a case series of presumed @entity2479 with their course of the disease, visual outcome, and association with rickettsial sub-type based on Weil-Felix test. FINDINGS: This is a retrospective study of 19 eyes of 10 @entity1 presented to a single institution. Cases diagnosed with presumed @entity2479 were identified from our database from March 2006 to October 2014 and studied retrospectively for @entity1 's demography, clinical presentation, and treatment. @entity1 with history of fever, @entity2479 , and a positive Weil-Felix test and a negative @entity12517 and dengue serology were diagnosed as presumed rickettsial @entity1596 . One @entity1 was diagnosed to have @entity23244 , and four were diagnosed to have Indian tick typhus. Nine @entity1 had bilateral presentation. One @entity1 had history of @entity235 tick bite, and four @entity1 had @entity1910 . All the @entity1 presented between 2 and 4  weeks after a fever. CONCLUSIONS: @entity2479 on posterior pole with recent history of fever with or without @entity1910 and a positive Weil-Felix test may suggest a rickettsial etiology. Its ocular manifestation could be an immune response to recent systemic @entity281 . Indian tick typhus and @entity23244 could be the common sub-types seen in our population. Although it has aggressive presentation, it has a good visual prognosis.
