Cure8 research brief
IBD may involve small-vessel changes beyond the gut. If reproducible, retinal microvascular alterations detectable by OCTA could offer a non-invasive window into systemic microvascular involvement in IBD.
Adults with IBD (Crohn's disease or ulcerative colitis), gastroenterologists, ophthalmologists, and researchers studying IBD-related systemic effects or vascular biomarkers.
The authors examined OCTA measures (superficial and deep capillary plexus vessel density, foveal avascular zone metrics, FD300) in 65 people with IBD and 49 healthy controls.
The main finding was a statistically significant reduction in DCP vessel density in IBD across several retinal regions; changes in the superficial plexus were smaller and mainly seen in ulcerative colitis. FD300 was modestly reduced and there was a weak negative correlation between disease activity in Crohn's disease and DCP vessel density.
This report is based on the article abstract provided by the journal (Digestive and Liver Disease). It summarizes the study methods and results as presented in the source; Cure8 has not re-analyzed the full study data.
This classification and note are grounded in the article abstract provided by the journal. The study reports subclinical retinal vessel density differences between IBD patients and controls but does not report downstream clinical outcomes or changes to management.

New PET tracers like FAPI could better detect fibrosis and stromal activity than standard FDG-PET, which may improve imaging of fibrostenotic Crohn's disease. For people with IBD, improved imaging might eventually help...
Detecting neoplasia early is a central goal of IBD surveillance; this study suggests virtual chromoendoscopy may find more lesions than dye or white light in real-world practice, which could influence how surveillance is...
