Age-related macular degeneration (AMD) is a chronic and progressive disease of the central retina that causes vision loss in people over 50 years of age. With an understanding of the role of VEGF in AMD, intravitreal anti-VEGF agents are used as the most important therapeutic tool in the management of AMD. In this review we try to discuss intravitreal ranibizumab treatment and treatment regimens in wet (neovascular) age-related macular degeneration.

Purpose. To report our experiences in patients with age-related macular degeneration (AMD) treated initially with intravitreal ranibizumab and then switched to bevacizumab. Methods. We retrospectively reviewed the records of 7 patients (7 eyes) who were treated with monthly injections of intravitreal ranibizumab and then switched to injections of bevacizumab (every 6 weeks) for six months. The best-corrected visual acuity measurements (BCVA) and optical coherence tomography (OCT) were performed at the baseline examination and then at each visit. The Wilcoxon signed-rank test was used for the statistical analysis. Results. Following three monthly ranibizumab treatments, there was no significant difference in the BCVA, while the foveal retinal thickness (FRT) significantly decreased (). Switching from ranibizumab to bevacizumab resulted in maintenance (57.2%) of the BCVA and a further decrease in the FRT () after 6 months. Conclusions. Switching to intravitreal bevacizumab may be effective in patients who wish to discontinue intravitreal ranibizumab treatment due to the high cost.

Introduction: The results of intravitreal ranibizumab treatment for exsudative age-related macular degeneration have been favourable until this time. Aim: To evaluate the two-year functional and anatomic results of intravitreal ranibizumab treatment. Method: 46 patients (age: 75±9.1 years) were included in a prospective single center study. Treatment regimen was the following: monthly 0.5 mg ranibizumab was administered in the first 3 months, and later as required (pro re nata). The change of best corrected visual acuity and central retinal thickness was followed. Results: The visus change at the end of the follow-up time was not statistically significant compared to baseline (p = 0.760) and the at the end of the first year (p = 0.154). Central retinal thickness decreased significantly compared to baseline (p = 0.000001), but the change was not statistically significant compared to the end of the first year (p = 0.875). Conclusions: Patients with neovascular macular degeneration treated with intravitreal ranibizumab using pro re nata regimen have stable visus for long term, and the exsudation could be reduced efficiently.

AbstractA remarkable proportion of neovascular age-related macular degeneration (nAMD) patients respond rather poorly to ranibizumab treatment, in spite of the minimum 4-week follow-up and treatment interval. Usually, retreatments are based on nAMD activity as evaluated by Spectral-domain Optical coherence Tomography (SD-OCT), biomicroscopic fundus examination and visual acuity changes. In this prospective pilot study, we aimed to study SD-OCT changes in a high-frequent follow-up manner (weekly (month 0–6), biweekly (month 7–12)) throughout the first year, which consequently led to intravitreal ranibizumab being administered up to biweekly. Best corrected visual acuity (BCVA) was already significantly improved at week 2. Central retinal thickness (CRT), intraretinal and subretinal fluid (SRF) were significantly improved from week 1 onwards. Half of the patients showed nAMD activity at week 2 or 3 and received the first retreatment earlier than 4 weeks after baseline injection. In total, 46% of retreatments were already applied 2 or 3 weeks after the previous treatment. Greater range of CRT and SRF fluctuation during follow-up was associated with lower final BCVA. Lower baseline BCVA and better SRF improvement at week 2 was associated with greater BCVA improvement. In conclusion, high-frequency SD-OCT follow-up provided a good option for adapting treatment in nAMD individually.
