[Pharmacokinetics of intravitreal anti-VEGF drugs in vitrectomized eyes].

Neovascular retinal diseases pose a significant burden, often resulting in visual impairment. Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs serves as the primary therapeutic approach. Nonetheless, certain patients necessitate continued anti-VEGF treatment post-vitrectomy or other ocular surgeries. Emerging evidence suggests that variations in surgical techniques and postoperative vitreous cavity management may induce distinct intraocular pharmacokinetics (PK) of anti-VEGF agents following vitrectomy, prompting potential adjustments in therapeutic strategies. This review offers a thorough examination of the pharmacokinetic determinants impacting anti-VEGF drugs and their intraocular dynamics post-vitrectomy.
