AIM: To evaluate the visual function and visual quality of patients with diabetic macular edema treated with conbercept injection.

METHODS: The average change of contrast sensitivity(CS), best corrected visual acuity(BCVA), central retinal thickness(CRT)and NEIVFQ-25 score were observed for 3mo after intravitreal injection of conbercept in 43 eyes of 38 patients with diabetic macular edema.

RESULTS: The mean CS increased from(1.060±0.14)units to(1.47±0.31)units at 12wk after intravitreal injection of conbercept(P<0.05). The average LogMAR BCVA decreased significantly from 0.535±3.32 to 0.333±0.11 at 12wk(P<0.05), and the average CRT decreased significantly from 369.45±36.42μm to 226.53±39.48μm at 12wk(P<0.05). There is not a correlation between the changes in CRT and BCVA and the improvement of CS. The NEIVFQ-25 score improved in 30 cases(79%)from baseline to 12wk. 6 cases(16%)had no change in the NEIVFQ-25 score, and 2 cases(5%)declined in the NEIVFQ-25 score.

CONCLUSION: The treatment of conbercept injection for diabetic retinal macular edema can significantly improve the visual function and the quality of life.
