Captopril and vascular endothelial growth factor in a mouse model of retinopathy.

Purpose: Angiotensin converting enzyme (ACE) inhibition has been shown in animal models of retinopathy and in patients with diabetes to improve retinal neovascularization. The mechanism is not clearly identified, but could potentially be mediated via vascular endothelial growth factor modification. The objective of this study was to determine the effect of captopril, an angiotensin converting enzyme (ACE) inhibitor, on retinal VEGF, VEGF-R1, and VEGF-R2 expression in a mouse model of oxygen induced retinopathy (OIR).

Ibuprofen improves oxygen-induced retinopathy in a mouse model.

Purpose: Retinopathy of prematurity is a developmental vascular anomaly occurring in the incompletely vascularized retina of the premature infant. Ibuprofen is a nonsteroidal anti-inflammatory agent similar to indomethacin, but with less pronounced side-effects. The goal of the study was to test the hypothesis that ibuprofen would improve oxygen-induced retinopathy in a mouse model.
