结果:与术前相比,A组患者术后2wk,1mo DCP血流密度显著增加、CMT明显降低、BCVA明显改善(均P<0.05),B组患者术后1mo CMT降低、BCVA改善(均P<0.05)。术后2wk、1mo,A组患者DCP血流密度较B组明显增加(43.37%±2.72% vs 41.03%±2.60%,45.01%±2.28% vs 41.20%±2.43%,均P<0.05),CMT较B组明显降低(303.4±30.36μm vs 329.60±31.47μm,268.67±30.27μm vs 319.40±28.63μm,均P<0.05),BCVA(LogMAR)较B组明显改善(0.28±0.11 vs 0.40±0.13,0.23±0.14 vs 0.38±0.15,均P<0.05)。
结果:治疗前两组患者眼压无差异(46.2±9.41mmHg vs 49.1±10.15mmHg,P>0.05),治疗后1wk,1、6mo A组患者眼压均低于B组(P<0.05)。治疗后6mo,A组视力、眼压控制率(95%)、新生血管消退情况(91%)均优于B组(P<0.05),但随访期间两组患者并发症发生率无差异(P>0.05)。
Purpose: To evaluate the efficacy and safety of intravitreal bevacizumab in proliferative diabetic retinopathy (PDR) patients. Methods: This interventional case series study included 15 eyes of 10 patients with bilateral PDR: 13 eyes with severe PDR and active new vessels (NV) and two eyes with recurrent vitreous haemorrhages. Study eyes received a single intravitreal injection of 1.25 mg (0.05 ml) bevacizumab. All eyes were followed up for 3 months, and eight of them for 9 months. Reinjection was performed in three eyes 4–6 months after the first injection. Study eyes were evaluated by fluorescein angiography at baseline, 1, 3 and 9 months. Quantitative planimetric analysis (QPA) of NV area was measured before and after treatment. All eyes received or completed panretinal photocoagulation (PRP) 1 month after the first injection. Results: As early as at 1 month, all study eyes had a regression (paired t‐test, P =0.01) of QPA‐estimated NV area. The eyes with recurrent vitreous haemorrhages had clearing of bleeding. These early effects were maintained at 3 months for all eyes and tended to be stable at 9 months. The fast and measurable efficacy of bevacizumab allowed a subsequent complete and safe PRP. Conclusion: Intravitreal bevacizumab did not reveal any side‐effects and was effective in the regression of NV areas and the resolution of vitreous haemorrhages. This approach is potentially useful in allowing (within a planned temporal window) a safe and efficient PRP to be performed while minimizing the risk of its complications. 相似文献
