AIM:

To observe the effect of intravitreal injection of ranibizumab in the treatment of retinal vein occlusion macular edema(RVO-ME), and to apply Logistic regression analysis to screen the factors that affect the vision recovery of patients. <p>

METHODS:

A total of 106 patients(106 eyes)with retinal vein occlusion and macular edema who were treated in the ophthalmology clinic of our hospital from January 2018 to June 2019 were selected for the study. The clinical data of the patients were retrospectively analyzed and all were given 0.05mL ranibizumab. The monoclonal antibody was injected into the vitreous cavity of the affected eye, and the patients were followed up to observe the treatment effect. The patients were divided into good group and poor group according to the degree of vision recovery after 3mo of treatment, and the two-class Logistic regression analysis was used to screen the factors that affect the vision recovery of patients.<p>

RESULTS:

The Logarithm of the minimum angle of resolution(LogMAR)of the affected eye at 1d, 1wk, 1, and 3mo after treatment was significantly lower than before treatment, and the macular foveal retinal thickness(CRT)was significantly lower than before treatment. The difference was statistically significant(all P<0.05), and there was no significant difference in the average intraocular pressure of the affected eye before and after treatment(P>0.05). During and after the treatment, the patient did not develop complications such as endophthalmitis, increased intraocular pressure, lens opacity, and retinal detachment. Logistic regression analysis showed that there was no capillary perfusion in the foveal area of the macula and the center of the macula before treatment. Incomplete outer membrane and incomplete inner plexiform layer structure in the concave area are risk factors that affect the efficacy of ranibizumab injection. <p>

CONCLUSION:

Intravitreal injection of ranibizumab in the treatment of retinal vein occlusion combined with macular edema is effective and safe in the short term. It can effectively reduce macular edema of the affected eye, improve vision, and normal intraocular pressure after treatment, and it is easy to operate and effective. It has the advantages of repeating, little damage to tissues, no obvious adverse reactions, less pain for patients, economical and practical. In addition, the lack of capillary perfusion in the foveal area of the macula before treatment, the incomplete outer membrane of the foveal area, and the incomplete structure of the inner plexiform layer are risk factors that affect the efficacy of ranibizumab in the treatment of retinal vein occlusion and macular edema.
