ABSTRACT.Purpose: To evaluate effectiveness, tolerability and safety of repeated intravitreal injections of 0.5 mg ranibizumab for the treatment of neovascular agerelated macular degeneration in routine medical practice in Germany. Methods: A noninterventional study with 3470 patients treated in 274 medical centres according to German guidelines, with monthly intravitreal injections of 0.5 mg ranibizumab during upload (3 months) followed by a maintenance phase (9 months) with reinjections if medically indicated. Results: Mean injection rate was 4.34 (SE = 0.05; median = 3.0). Best-corrected visual acuity (BCVA) remained stable (mean change 0.02 LogMAR, SE = 0.01, p = 0.0169) and central retinal thickness (CRT) decreased (by )78.9 lm, SE = 2.95 lm, p < 0.0001). The NEI-VFQ 25 summary score showed a positive stabilization with a mean change of 0.73 (SE = 0.37, p = 0.0501) compared with baseline. Adverse events were documented for 6.5% of the patients with 3.9% of these events being classified as serious. Conclusions: The number of administered intravitreal injections of ranibizumab over the first year of treatment was very low but still achieved a stabilization of BCVA, a reduction in CRT and maintained vision-related quality of life. The management of patients with neovascular AMD in Germany needs to be improved to achieve better treatment results.

Neuronal activity patterns contain information in their temporal structure, indicating that information transfer between neurons may be optimized by temporal filtering. In the zebrafish olfactory bulb, subsets of output neurons (mitral cells) engage in synchronized oscillations during odour responses, but information about odour identity is contained mostly in non-oscillatory firing rate patterns. Using optogenetic manipulations and odour stimulation, we found that firing rate responses of neurons in the posterior zone of the dorsal telencephalon (Dp), a target area homologous to olfactory cortex, were largely insensitive to oscillatory synchrony of mitral cells because passive membrane properties and synaptic currents act as low-pass filters. Nevertheless, synchrony influenced spike timing. Moreover, Dp neurons responded primarily during the decorrelated steady state of mitral cell activity patterns. Temporal filtering therefore tunes Dp neurons to components of mitral cell activity patterns that are particularly informative about precise odour identity. These results demonstrate how temporal filtering can extract specific information from multiplexed neuronal codes.
