[Finding of Strongyloides stercoralis infection, 25 years after leaving the endemic area, upon corticotherapy for ocular trauma].

In the field of ophthalmology, indications for high-dose corticotherapy are various. This paper reports the case of a Caledonian man who presented with intestinal strongyloidiasis, discovered 25 years after he had left the endemic area. A checkup before corticotherapy for traumatic retina edema provided the diagnosis of the infection. The authors emphasize the importance of searching for Strongyloidiasis stercoralis larva before initiating corticotherapy, as it is the main treatment responsible for parasitic dissemination. The most severe form of strongyloidiasis, the disseminated form, has a high mortality rate: 70%-90%. The definitive diagnostic test is enhanced larva recovery, which should be proposed to every patient returning from endemic area, people with precarious hygiene or with high eosinophilia or intestinal symptoms of chronic infection. Delay in diagnosing strongyloidiasis frequently results in death, despite vigorous treatment.
