Abstract:
Objective To investigate the efficacy and safety of intravitreal ranibizumab and (or) triamcinolone combined with laser photocoagulation for macular edema secondary to branch retinal vein occlusion (BRVO) during one year period.Methods The data of 31 eyes from 31 consecutive patients with macular edema secondary to BRVO during one year follow-up visit were retrospectively analyzed.Mean best corrected visual acuity (BCVA) logMAR was (0.74±0.36) and mean central retinal thickness (CRT) was (484.48± 164.81) μm at baseline.All patients received standardized clinical comprehensive examinations including vision,intraocular pressure and optical coherence tomography for diagnosis before treatment.All patients received intravitreal injections of 0.5 mg ranibizumab (0.05 ml) at first visit.The continue PRN treatment were based on the visual acuity changes and the optical coherence tomography findings.Eyes received combined triamcinolone acetonide 0.05 ml (40 mg/ml) and ranibizumab for macular edema recurrence after two injections of ranibizumab and received laser photocoagulation during 10-14 days after third injections of ranibizumab.Mean injection of ranibizumab was 3.52± 2.01,15 eyes with triamcinolone acetonide (0.84 ± 1.21),21 eyes with laser photocoagulation (0.97± 0.95) and 12 eyes with three treatment.Compared the visual acuities and CRTs of the first and the last visits by statistical analysis.Results Mean visual acuity improved significantly to 0.42±0.33 logMAR (t=6.611,P=0.000).Mean improvement of visual acuity was 2.90± 3.07 lines.A gain of three or more logarithmic lines was evaluated in 20/31 eyes (64.52％) at the last visit.Mean CRT was (326.19± 117.80) μm (t=4.514,P=0.000).Mean reduction of CRT was (333.58±134.17) μm.A decrease of 100 μm of CRT was evaluated in 17/31 eyes (54.84％).No severe ocular and systematic side effect was found.Conclusion The efficacy and safety of intravitreal ranibizumab and (or) triamcinolone combined with laser photocoagulation for macular edema secondary to BRVO were assured.
