[Prevention of intraocular pressure elevation following intravitreal injections]

Abstract

Determining the role of vascular endothelial growth factor (VEGF) in the pathogenesis of intraocular neovascularization prompted the development of anti-VEGF therapy. In general, these intravitreal injections (IVI) are considered relatively safe. One of the side effects that can occur after IVI of anti-VEGF agents is ocular hypertension, it can be acute or persistent. Numerous studies investigating the prevention of ophthalmic hypertension have been carried out in connection with the proven risk of short-term intraocular pressure (IOP) elevation after anti-VEGF injections. Scientific literature describes several methods of preventing intraocular pressure spikes after IVI: prophylactic medications, anterior chamber paracentesis, scleral decompression. Despite the significant number of publications, there is no universal consensus on the necessity of prevention measures for IVI of anti-VEGF drugs since the clinical benefits of slightly reducing the short-term IOP spikes remain unclear. This literature review analyzes the prospects of preventing ocular hypertension after IVI of anti-VEGF agents.
