Ranibizumab Treatment

Aims. To investigate the correlations between renal biomarkers and the treatment outcomes of ranibizumab for diabetic macular edema (DME). Methods. This hospital-based study retrospectively enrolled 88 eyes from 67 patients who had received one-year intravitreal ranibizumab treatment for DME. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) at baseline and during the follow-up period were recorded. BCVA and OCT characteristics at baseline and their changes after ranibizumab treatment were compared between different proteinuria and estimated glomerular filtration rate (eGFR) groups. Results. Of the 88 eyes studied, those with moderately increased proteinuria had a thicker central subfield foveal thickness (CFT) and a higher proportion of intraretinal cysts than those with no proteinuria (P=0.012 and 0.045, respectively) at baseline. After one year of ranibizumab treatment, the reduction in CFT was greater in patients with severely increased proteinuria than those with normal to mildly increased proteinuria (P=0.030). On the other hand, patients with an eGFR <30 tended to have poorer visual improvements than those with normal eGFR (P=0.044). Conclusions. After ranibizumab treatment for DME, patients with severe proteinuria tended to gain better anatomical improvement, while those with poor eGFR tended to have poorer visual improvement.

Ranibizumab Treatment

Diabetic macular edema (DME) is one of the most common causes of visual loss in patients with diabetic retinopathy (DRP). The prognosis of central involved diabetic macular edema has improved after anti-VEGF treatments. Intravitreal ranibizumab was the first anti-VEGF agent approved by the FDA for the treatment of diabetic macular edema. Despite the fact that it is a pathogenic treatment, it has brought some challenging situations on its own. In most studies, optimal dose and combined treatment were evaluated in terms of treatment efficacy. Recent studies revealed that ranibizumab treatment is effective in DRP and proliferative DRP regression as well as in diabetic macular edema treatment. In this article, we aimed to review the effects of Ranibizumab treatment on visual acuity, central macular thickness in patients with diabetic retinopathy, and diabetic macular edema through studies.

Purpose: To evaluate the outcome of second-line intravitreal ranibizumab treatment in eyes with diabetic macular edema having persistent edema following initial therapy with intravitreal bevacizumab. Methods: Diabetic macular edema treated with ranibizumab following bevacizumab failure in Israel was a retrospective, multi-center study. Consecutive eyes with persistent diabetic macular edema following at least three previous intravitreal bevacizumab injections prior to intravitreal ranibizumab, at least three-monthly intravitreal ranibizumab injections and at least 12 months of follow-up were included. Data collected included demographics, ocular findings, diabetes control, details of intravitreal bevacizumab and ranibizumab injections, and visual and anatomical measurements before and after intravitreal ranibizumab treatment. Results: In total, 202 eyes of 162 patients treated at 11 medical centers across Israel were included. Patients received a mean (±standard deviation) of 8.8 ± 4.9 intravitreal bevacizumab injections prior to the switch to intravitreal ranibizumab. A mean of 7.0 ± 2.7 intravitreal ranibizumab injections were given during the 12 months following the switch to intravitreal ranibizumab. The median central subfield retinal thickness (±interquartile range) by spectral-domain optical coherence tomography decreased from 436 ± 162 µm at baseline to 319 ± 113 µm at month 12 (p < 0.001). Median logMAR visual acuity (±interquartile range) improved from 0.40 ± 0.48 at baseline to 0.38 ± 0.40 at month 12 (p = 0.001). Linear regression suggested that higher number of intravitreal ranibizumab injections and higher pre-switch central subfield retinal thickness were associated with favorable visual outcome. Higher number of intravitreal bevacizumab injections and the presence of intraretinal fluid before the switch lessened the odds of favorable outcome. Conclusion: Switching from bevacizumab to ranibizumab in persistent diabetic macular edema was associated with anatomical improvement in the majority of eyes and ⩾2 lines of vision improvement in 22% of eyes.
