ObjectivesTo observe the clinical efficacy and complications of conbercept combined with a 577-nm micropulse laser in patients with macular edema (ME) secondary to non-ischemic central retinal vein occlusion (CRVO).MethodsA total of 153 patients who were diagnosed with non-ischemic CRVO-induced ME and treated by Shijiazhuang People's Hospital during January 2019 and January 2021 were included in this study. The patients were divided into a control group and an experimental group by choice of treatment. The control group was treated by conbercept alone, while the experimental group underwent laser treatment on this basis. The best corrected visual acuity (BCVA) was determined by the internationally standardized logarithm of the minimum angle of resolution (logMAR) chart and the central macular thickness (CMT) was measured by optical coherence tomography (OCT) before and at one and three months after treatment. Complications such as conjunctival hemorrhage and elevated intraocular pressure (if any) were recorded during the 3-month follow-up period.ResultsConbercept could improve the BCVA and CMT of patients with non-ischemic CRVO (P <0.05, respectively), and the combined use of conbercept with micropulse laser treatment yielded greater improvements in these measures compared with the pre-treatment condition (P <0.05, respectively); moreover, the differences between the control group and the experimental group were statistically significant (all P <0.05). The two groups had similar complication rates and did not record any serious adverse reactions.ConclusionsConbercept combined with 577-nm micropulse laser treatment can benefit patients with non-ischemic CRVO-induced ME by improving their visual acuity and relieve ME symptoms. As a regimen of impressive clinical efficacy, it is of great value for wide application in clinical practice.Copyright: © Pakistan Journal of Medical Sciences.
