Study compares efficacy of ranibizumab and aflibercept in diabetic retinopathy treatment
Both ranibizumab (LU) and aflibercept (AF) injections into the vitreous cavity effectively reduce the expression of vascular-related factors in patients with diabetic retinopathy (DR), however, AF demonstrates a more significant inhibitory effect on inflammatory factors in the short term after treatment compared to LU, according to a study.
Participants were randomly divided to receive LU (n = 47) or AF (n = 47).
The results demonstrated a significant decrease in VEGF levels and an increase in pigment epithelium-derived factor (PEDF) levels in both groups post-injection (P < 0.001). Notably, no significant differences were observed between the LU and AF groups in terms of operative time, intraoperative bleeding rate, incidence of medically induced fissures, BCVA, and CMT.
At the 2-month mark after surgery, the AF group exhibited lower levels of IL-6, IL-8, and MMP-9 inflammatory factors compared to the LU group.
The study ultimately concluded that both LU and AF injections into the vitreous cavity effectively reduced the expression of vascular-related factors in DR patients. Notably, AF displayed a more pronounced inhibitory effect on inflammatory factors in the short term after treatment.
