结果:治疗后2wk,1、2、3mo,B组患者CMT、CMV、BCVA均明显优于A组(P<0.05)。随访3mo,B组患者视力提高比例显著高于A组(65% vs 38%,P<0.05),玻璃体腔注射次数显著低于A组(P<0.05),但两组患者并发症发生情况(5% vs 0%)无明显差异(P=0.999)。
结果:两组患者治疗前一般资料比较无差异(P>0.05),两组患者BCVA(0.63±0.13 vs 0.76±0.19; t=4.123,P<0.001)、CMT(305.89±58.76 vs 340.26±60.41μm; t=2.954,P=0.004)比较有差异,而两组患者眼压对比(12.11±1.82 vs 12.24±1.59mmHg; t=0.389,P=0.700)无差异; 观察组患者术后1mo视野灰度值、视野平均缺损值显著低于对照组(P<0.001); 观察组患者术后1mo 30°视野平均光阈值敏感度显著高于对照组(P<0.001)。
AIM: To evaluate the efficacy and safety of intravitreal injection of conbercept in patients with neovascular age-related macular degeneration (AMD).
METHODS: Retrospective review of 66 eyes of 63 patients with neovascular AMD. All patients received 0.5 mg intravitreal injections of conbercept monthly for 3 consecutive months, and then pro re nata treatment was performed. The changes of best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and after treatments. Minimum follow-up time was 12mo. SPSS 22.0 statistical software was used for statistical analysis.
RESULTS: The mean BCVA and CMT of 66 eyes (63 patients) were 1.11±0.60, 533.20±219.95 μm at baseline, and were 0.68±0.38, 310.28±125.60 μm at 3mo. No subjects were lost during the first three months, the improvements were all significantly (P<0.05). During the whole follow-up time of 12mo, 15 subjects (18 eyes) were lost. The mean BCVA and CMT of the rest 48 eyes with the follow-up time at least 1y were 0.83±0.46 and 547.59±196.77 μm at baseline, after 3mo and 12mo of conbercept injections became 0.55±0.41, 318.24±141.29 μm and 0.55±0.51, 333.87±173.25 μm. The differences were significant (P<0.05). No serious complications were observed.
CONCLUSION: Intravitreal injection of conbercept appears to significantly improve visual acuity and anatomical outcomes in patients with neovascular AMD, no serious adverse reactions and complications are observed. 相似文献
AIM: To compare the safety and efficacy of conbercept intravitreal injection and half-dose photodynamic therapy (PDT) in treating chronic central serous chorioretinopathy (CSC).
METHODS: This study was retrospective. Thirty-seven patients (37 eyes) with chronic CSC received conbercept injections while 57 patients (57 eyes) were treated with half-dose PDT. All subjects were followed in 6mo. Outcome measures included change in best-corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and resolution of subretinal fluid (SRF).
RESULTS: There was no adverse event observed in either treatment group. At the 6-month follow-up, 26 eyes (70.3%) in the conbercept group and 54 eyes (94.7%) in the half-dose PDT group (P<0.05) reached full resolution of SRF. The mean logarithm of the minimum angle of resolution (logMAR) BCVA significantly improved (P<0.001) in both treatment groups with better outcome at early phase in the half-dose PDT group (2wk, 1, and 2mo, P<0.05). All subjects experienced significant CMT improvement (P<0.001) with no statistical difference between the two groups (P>0.05). The SFCT also improved in all subjects (P<0.001) with better outcome in the half-dose PDT group (P<0.05).
CONCLUSION: Both intravitreal conbercept and half-dose PDT are safe to use in treating chronic CSC. By 6mo, both treatment groups are efficacious in improving BCVA, reducing CMT and SFCT, and resolving SRF in eyes with chronic CSC. Half-dose PDT may show better outcome at initial phase of treatment in chronic CSC. Longer follow-up period is necessary to study for long-term effect and safety. 相似文献
