Panretinal Photocoagulation Using Short-Pulse Laser Induces Less Inflammation and Macular Thickening in Patients with Diabetic Retinopathy

Figure 4

Alteration in the vitreous levels of inflammatory and angiogenic cytokines after panretinal photocoagulation (PRP) using the conventional laser with 500 spots (Conv 500s), short-pulse laser (SPL) with 500 spots (SPL 500), and SPL with 1000 spots (SPL 1000s). Concentrations of VEGF, IL-6, ICAM-1, and MCP-1 in the vitreous body were measured before and on 1, 7, and 14 days after PRP. Statistically significant difference as compared to the Conv group (). Vertical bars indicate standard deviation. ().
