ABSTRACT
Objective To evaluate the effectiveness of repeated intravitreal conbercept injection in patients with macular edema (ME) of retinal vein occlusion (RVO),guided by optic coherence tomography (OCT).Methods It is a retrospective case study.Forty patients (40 eyes) diagnosed as ME secondary to RVO were enrolled in this study.There were 19 males (19 eyes) and 21 females (21 eyes),with the mean age of (53.58 ± 13.19) years and the mean course of 1.5 months.The best corrected visual acuity (BCVA),indirect ophthalmoscopy,fundus fluorescein angiography (FFA) and OCT were performed.The mean baseline of BCVA,central macular thickness (CMT) were 0.25 ± 0.18 and (509.48 ± 170.13) μm respectively.All the patients were treated with 10.00 mg/ml conbercept 0.05 ml (including conbercept 0.5 mg).Follow-up of these patients was 1 to 6 months after treatments,the BCVA,fundus manifestations,OCT were retrospectively observed by every month,the FFA was retrospectively observed by every 3 months.When there was retinal edema or CMT ≥ 50 μm by OCT during follow-up,those patients were retreated with intravitreal conbercept injection.The changes of the BCVA,CMT were evaluated before and after treatment.Meanwhile,complications in eyes related to medicine and treatment methods were evaluated too.Results At the 6 months,the BCVA was improved (increase≥2 lines) in 25 eyes (62.50%),stabilized (± 1 line) in 13 eyes (32.50%) and decreased 2 lines in 2 eyes (5.00%).Retinal hemorrhage and exudates were absorbed in most patients.FFA showed no fluorescein leakage in 1 1 eyes (27.50%),minor fluorescein leakage in 26 eyes (65.00%),and retinal capillary non-perfusion in 3 eyes (7.50%).OCT showed absorption of the subretinal fluid.The mean CMT were (235.20± 100.44) μm at 6 months.Intravitreal injection of conbercept was applied for 4 times in 8 eyes (20.00%),3 times for 18 eyes (45.00%),and 2 times for 14 eyes (35.00%).The mean number of intravitreal injection was 2.85 times.There were no ocular or systemic adverse events observed in all patients.Conclusion Intravitreal conbercept injection is an efficacy and safe treatment for the patients with ME of RVO guided by OCT.It can stabilize and improve the visual acuity.
