The Five MostWeird ROCK inhibitor Tips... And The Ways To Utilise Them!!
49 The first group treated with PRN ranibizumab was guided by VA stabilization criteria and the second group was guided by disease activity criteria. RADIANCE showed that patients treated with both PRN regimens of ranibizumab provided superior BCVA gains in comparison with patients treated with vPDT at 3 months. Retreatment criteria did not affect the Crizotinib price 6-month results in the ranibizumab treatment groups. At 12 months, irrespective of retreatment criteria, ranibizumab was effective in improving and sustaining BCVA and was generally well tolerated in patients with mCNV.49 Moreover, patients who were previously treated by vPDT could still gain vision when they were switched to ranibizumab. Nevertheless, patients initially treated by vPDT and later switched to IVR did not achieve the Non-specific serine/threonine protein kinase same visual gains as those treated initially with IVR. Anatomical outcome improvements were observed with both IVR and vPDT.49 RADIANCE also revealed significant improvements in several quality-of-life parameters for patients treated with ranibizumab compared with vPDT, which were maintained through to 12 months.52 Franqueira et al53 published the 3-year follow-up of a prospective study that included 40 eyes with mCNV treated with ranibuzimab. The mean VA improved significantly from 55.4 ETDRS letters at baseline to 63.4 letters at 36 months. Thirty-five percent of the patients gained ��3 lines at 36 months. A mean of 4.1 injections was used in the first year, 2.4 in the second year, and 1.1 in the third year. Iacono et al54 reported the results of one of the largest randomized studies of IVB versus IVR in treatment-na?ve mCNV. VA improved significantly after anti-VEGF therapy and improvement remained statistically significant at 18 months. Moreover, there was no significant difference in VA between eyes treated with bevacizumab or ranibizumab at all time points. Ruiz-Moreno et al55 demonstrated the long-term efficacy of intravitreal Selleck ROCK inhibitor injections of both bevacizumab and ranibizumab. They showed that the mean number of letters read was 46.1 at baseline, 55.5 at 1 year, 50.1 at 2 years, 54.2 at 3 years, and 53.1 at 4 years. Recently, Freitas-da-Costa et al56 reported the long-term results of anti-VEGF therapy in mCNV. The mean change from baseline BCVA was significant at 2 years (+8.6 letters; P
