ABSTRACT
@#AIM: To investigate the clinical effectiveness of conbercept intravitreal injection combined with panretinal photocoagulation for ischemic central retinal vein occlusion.<p>METHODS: A retrospective study has been conducted on 80 patients(80 eyes)of ischemic central retinal vein occlusion diagnosed and treated at Dalian No.3 People's Hospital from January 2017 to January 2019. These 80 patients have been divided into two groups based on treatment methods. In Group A, 40 patients(40 eyes)were given 3+PRN intravitreal injection of conbercept combined with panretinal photocoagulation. In Group B, 40 patients(40 eyes)accepted the treatment of 3+PRN intravitreal injection with conbercept. The best corrected visual acuity(BCVA)and central macular thickness(CMT)before and after treatment were recorded respectively at 3mo, 6mo and 12mo, and the clinical effectiveness and adverse reactions were observed and documented.<p>RESULTS: After 12mo: In group A, BCVA improved from 1.05±0.58 to 0.41±0.37(<i>P</i><0.01).In group B, BCVA improved from 0.98±0.51 to 0.63±0.53(<i>P</i><0.01). There was no significant difference between the two groups(<i>P</i>>0.05). In group A, CMT changed from 592.30±79.75μm to 260.08±86.23μm(<i>P</i><0.01). In group B, CMT changed from 604.98±81.73μm to 406.83±162.97μm(<i>P</i><0.01).CMT was better in Group A than Group B(<i>P</i><0.01). The mean number of injections in group A(3.15±0.43 times)and group B(3.83±1.06 times)was statistically significant(<i>P</i><0.01). During follow-up, no adverse events happened in Group A. Two patients were neovascular glaucoma after central retinal vein occlusion in Group B.<p>CONCLUSION:It is safe and effective to use intravitreal injection of conbercept to treat central retinal vein occlusion. Combining intravitreal injection of conbercept with panretinal photocoagulation can significantly improve BCVA, lead to further regression of macular edema and a more stabilized positive effect. It proves to reduce recurrence rate of the central retinal vein occlusion and decrease the chances of any complications.
