Objective To observe the effect of macular retinal thickness (CMT) on the long-term visual prognosis after intravitreal injection of Conbercept combined with retinal laser photocoagulation for macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Methods A retrospective non randomized controlled study. Forty-one patients (41 eyes) of ischemic BRVO secondary ME were included in the study. Among them, there were 23 males (23 eyes) and 18 females (18 eyes). The average age was (56.49±8.94) years. The best corrected visual acuity (BCVA) and optical coherence tomography were performed. The mean logMAR BCVA was 0.82±0.41, and the mean CMT was (512.61±185.32) μm. According to the CMT reduction value at 1 month after treatment, the eyes were divided into no response group and response group, each has 15 patients of 15 eyes and 26 patients of 26 eyes respectively. The age and sex composition of the two groups were not statistically significant (t=−0.298, −1.708; P=0.767, 0.096), and the difference of frequency of injection was statistically significant (t=3.589, P=0.010), and there was no statistical difference between the patients with logMAR BCVA and CMT (t=2.056, −1.876; P=0.460, 0.070). The average follow-up was 8 months. The logMAR BCVA on 6 months after treatment was defined as long term vision. The changes of long term vision and CMT on 1 and 6 months of two groups after treatment were observed. Pearson correlation analysis showed that the correlation between long-term vision and age, logMAR BCVA before treatment, CMT before treatment, frequency of injection, and CMT value decreased 1 month after treatment. The correlation of long-term visual acuity with age, sex, logMAR BCVA before treatment, CMT before treatment, number of drugs before treatment, CMT reduction at 1 month after treatment, integrity of ellipsoid band and integrity of external membrane (ELM) were analyzed by multiple regression analysis. Results On 1 month after treatment, the CMT of the eyes was lower than that before treatment (231.48±177.99) μm, and the average integrity of ELM and ellipsoid were 0.56±0.50 and 0.41±0.50 respectively. On 6 months after treatment, the average logMAR BVCA of the eyes was 0.48±0.34. The results of Pearson correlation analysis showed that the long-term vision was positively correlated with the logMAR BCVA before treatment and the number of CMT reduction and the number of drug injection at 1 month after treatment (P＜0.05); there was no correlation with age and CMT before treatment (P＞0.05). The results of multiple regression analysis showed that the long-term vision was associated with logMAR BVCA before treatment, CMT reduction, ELM integrity, and the number of times of injection (P＜0.05), and no correlation with age, sex, CMT before treatment and the integrity of the ellipsoid (P＞0.05). On the 6 months after treatment, the logMAR BCVA in the non-response group and the response group were 0.86±0.23 and 0.26±0.14, and the average CMT was respectively (398.93±104.87) and (255.15±55.18) μm, and the average injection times were respectively (2.53±1.46) and (1.31±0.74) times. The average logMAR BCVA, CMT and injection times of the two groups were statistically significant (t=10.293, 5.773, 3.589; P=0.000, 0.000, 0.001). No complications related to drug or intravitreal injection occurred in all patients. Conclusion The long-term vision of ME secondary to BRVO after intravitreal injection of Conbercept combined with retinal laser photocoagulation was associated with the decrease of CMT and the integrity of the ELM after 1 month of treatment, no correlation was found between CMT and ellipsoid integrity before treatment.
