Objective To explore the influence factors of retinal neovascularization(RNV)on visual function after laser photocoagulation.Methods A total of 120 RNV patients who received laser photocoagulation in our hospital were included in the study from January 2021 to July 2023.Best corrected visual acuity(BCVA)were measured at 1 day before treatment and 3 months after surgery to assess the visual function,and pa-tients were divided into poor and good visual function groups based on BCVA at 3 months after surgery.The clinical data of two groups were com-pared,and the related factors were analyzed by multiple factors.Results The BCVA at 3 months after surgery was apparently higher than that at 1 day before treatment(P<0.05).There were no statistically significant differences in age,gender,body mass index,affected eye,history of smoking,drinking,hypertension,hyperlipidemia and coronary heart disease between the poor and good visual function groups(P>0.05),while there were statis-tically significant differences in disease course,BCVA and intraocular pressure before treatment,and history of diabetes between the poor and good visual function groups(P<0.05).Short disease course and low intraocular pressure before treatment were protective factors for the visual function of RNV patients after laser photocoagulation,while low BCVA before treatment and history of diabetes were risk factors for the visual function of patients.Conclusion The disease course,BCVA and intraocular pressure before treatment,and history of diabetes all affected the visual function of RNV patients after laser photocoagulation.Clinical attention should be paid to improve early assessment and timely intervention for patients with the above factors to improve their visual function after surgery.
