Predictors of visual recovery in patients with macular edema secondary to central retinal vein occlusion after treatment with Conbercept
Abstract Background The use of Spectral domain optical coherence tomography (SD-OCT) to evaluate the predictors of visual acuity-recovery in patients treated with conbercept for macular edema (ME) secondary to central retinal vein occlusion (CRVO) has rarely been seen. We collected 26 CRVO-ME patien...

We collected 26 CRVO-ME patients with different OCT measures at 6 months follow-up to identify the factors that are most strongly correlated with the best-corrected visual acuity (BCVA) post-treatment in CRVO-ME patients treated with conbercept. Purpose To evaluate the effectiveness of intravitreal conbercept injections for the treatment of CRVO-ME and to determine the major predictors of best-corrected visual acuity (BCVA) post-treatment. Methods A retrospective study methodology was used. Twenty-six eyes from 26 patients with CRVO-ME were enrolled in the study. After an initial intravitreal injection of conbercept (0.5 mg/0.05 ml), monthly injections for up to 6 months were given following a 1 + PRN (pro re nata) regimen. Data collected at monthly intervals included measurements of the logMAR BCVA, central subfield thickness (CST), macular volume (MV), photoreceptor layer thickness (PLT), outer nuclear layer thickness (ONLT), and the disrupted ellipsoid zone (DEZ). The correlation between BCVA, before and after injections, and each of CST, MV, PLT, ONLT, DEZ was analyzed. Results The logMAR BCVA in months 3 and 6 post-injection was significantly improved relative to the baseline. In this same period the CST, MV, PLT, ONLT and DEZ were also significantly improved relative to the baseline. There was a negative correlation between PLT and logMAR BCVA at months 3 and 6 after treatment (r = − 0.549, P < 0.001; r = − 0.087, P < 0.001). Conclusion Intravitreal injection of conbercept is an effective treatment for CRVO-ME. With 6 months of follow-up, logMAR BCVA and CST, MV, PLT, ONLT, DEZ improved. PLT was negatively correlated with the visual function in CRVO-ME patients after conbercept treatment, which may be a predictor of vision recovery in patients with CRVO-ME.Qi ZhangYinfen HouXiao CaoRongrong ZhangYinping LiuChenghua WeiChangfan WuLixin MeiPengfei ZhangBMCarticleCRVO-MEConberceptBest corrected visual acuity, predictive factorOphthalmologyRE1-994ENBMC Ophthalmology, Vol 21, Iss 1, Pp 1-7 (2021) |
