Inhibition of laser induced rats choroidal neovascularization by intravitreous injection of sEphB4-HSA.

ABSTRACT:

Background

Choroidal neovascularization (CNV) is a leading cause of central vision loss complicated with age-related macular degeneration. Although intravitreal anti-VEGF therapy is widely used in wet age-related macular degeneration, optimal treatment regimens for the disease are still under investigation. EphrinB2 and EphB4 regulate angiogenesis, and interruption of EphB4/ephrinB2 has been demonstrated to inhibit angiogenesis. In the current study, we studied the effects of soluble EphB4 (sEphB4) on laser induced CNV in a rat model by intravitreous injection and the underlying mechanism.

Methods

Male rats (Brown-Norway) were used in the study. CNV was induced by laser and the sEphB4 was injected intravitreous after laser at days 3 and 7. The CNV lesions were evaluated by t
