Ocular involvement in STEC-associated hemolytic uremic syndrome.

Background: Hemolytic uremic syndrome (HUS) is a systemic thrombotic microangiopathy characterized by hemolytic anemia, thrombocytopenia, and variable kidney involvement. Extrarenal thrombotic microangiopathy occurs in central nervous system (CNS), colon, and other organ systems, but ocular involvement is rarely recognized. This study aimed to analyze frequency and severity of ocular involvement in STEC-HUS, and the relationship between ocular involvement and disease severity, with emphasis on CNS, kidney, and colonic disease.

[Lymphoma revealed by isolated obliquus inferior muscle involvement in exophthalmia].

Orbital lymphomas account for 4% of nontraumatic orbital disorders. We report the case of a 54-year-old patient who presented with binocular diplopia associated with right exophthalmia with an isolated obliquus inferior localization. This lymphomatous localization was unexpected, as lymphomas are described more often in the rectus superior and inferior muscles.
