ABSTRACT
AIM:
To analyze the correlation between optical coherence tomography(OCT)parameters and central retinal vein occlusion of macular edema secondary(CRVO-ME), and compare the clinical efficacy of ranibizumab combined with laser photocoagulation and ranibizumab alone in the treatment of CRVO-ME.METHODS:
There were 43 case with 43 eyes of patients in CRVO-ME diagnosed in our hospital from January 2020 to December 2020 included in the present study and divided into two groups, namely A and B. Patients in group A were treated with ranibizumab combined with laser photocoagulation, while patients in group B were treated with ranibizumab alone. The structure of outer retina and “SAVE” scores were observed and estimated using OCT and fluorescein angiography(FFA)examination before and after the treatment at 1, 3, 6, 12mo, and then analyzed their correlation with best corrected visual acuity(BCVA, LogMAR). The BCVA, central macular thickness(CMT), intraocular pressure and average number of drug injections were also compared between the two groups before and after treatment.RESULTS:
At 12mo after treatment, the BCVA in the OCT baseline external limiting membrane(ELM)intact group and baseline ellipsoid zone(EZ)intact group before and after treatment were significantly improved than those of the fracture group(0.47±0.16 vs 0.21±0.15, P=0.013; 0.44±0.20 vs 0.25±0.17, P=0.008). There was no statistically significant difference in BCVA changes between baseline RPE fracture group and RPE intact group(P>0.05). The number of patients with “S” and “A” at 1 score decreased significantly at 12mo after treatment in both groups, the BCVA of patients with “V” and “E” at 0 score before treatment was significantly improved than those patients at 1 score(all P<0.05). The BCVA and CMT of patients after treatment in groups A and B were both significant improved compared with before treatment(P<0.05). There were no significant differences in the BCVA and CMT in the number of drug injections between the two groups(P>0.05). In addition, there were no severe complications such as secondary glaucoma and endophthalmitis in both groups.CONCLUSION:
Baseline status of ELM and EZ, presence or absence of vitreoretinal abnormalities(V), and focal leakage(E)could suggest the treatment efficacy of CRVO-ME. Ranibizumab in the treatment of CRVO-ME demonstrates prominent efficacy and great safety, and there was no better effect was observed when combined with laser photocoagulation.
