A 2013 study published in the journal Pediatrics, concluded it was actually viral meningoencephalitis that caused Ingalls' blindness, based on evidence from first-hand accounts and newspaper reports of her illness as well as relevant school registries and epidemiologic data on blindness and infectious diseases. Between 1881 and 1889, Ingalls attended the Iowa Braille and Sight Saving School in Vinton, Iowa.
