Background<\/strong> — Intravenous administration of vascular endothelial growth factor (VEGF)-inhibiting drugs is associated with adverse gastrointestinal (GI) events.

Objective<\/strong> — The objective was to assess risks for GI adverse events associated with intravitreal injections of VEGF-inhibiting drugs. <\/p>\n

Methods<\/strong> — The researchers conducted a population-based, nested case-control study of 114,427 older adults in Ontario, Canada, with retinal disease identified between 1 November 2005 and 30 April 2011.

Results<\/strong> — Patients experiencing adverse events were equally as likely as matched controls to have been exposed to bevacizumab or ranibizumab.

For ranibizumab they were 1.25 (95 % CI 0.88-1.77) for upper GI ulceration, 1.12 (95 % CI 0.83-1.52) for diverticular disease, 0.85 (95 % CI 0.51-1.40) for pancreatitis, 0.77 (95 % CI 0.53-1.11) for cholelithiasis, and 0.83 (95 % CI 0.44-1.56) for cholecystitis.
