Treat and extend regimen with aflibercept for chronic central retinal vein occlusions: 2 year results of the NEWTON study.
Article in International journal of retina and vitreous, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo determine whether aflibercept (Eylea; Regeneron Pharmaceuticals, Inc., Tarrytown, NY) could continue to extend the macular edema free interval in patients on a treat and extend (TAE) with non-ischemic central retinal vein occlusions (CRVOs) previously treated with ranibizumab (Lucentis; Genentech, Inc., South San Francisco, CA) or bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) in the second year.
methodsTwenty patients with macular edema secondary to non-ischemic CRVOs previously treated with ranibizumab or bevacizumab were prospectively treated with intravitreal aflibercept injection (IAI) using a TAE dosing regimen. Injection frequencies were extended 2 weeks if there were no signs of disease activity on OCT or change in visual acuity. In the second year of the study, patients who have recurrences of macular edema could be re-challenged with a longer treatment interval under the following criterion: absence of any macular edema on three consecutive visits with the same treatment interval.
resultsTwenty patients had an average duration of a CRVO for 22 months (range 7-90) and averaged an anti-VEGF treatment every 42 days (range 28-60 days). The macular edema free interval increased from 38 to 75 days when switched to aflibercept (p = 0.000003) at month 24. There was an average increase of 37 days (median 34 days; range 0-91 days) in the macular edema free interval with aflibercept. At the month 24 visit, 50% (8/16) went > 12 weeks with a macular edema free interval between IAI. There was an improvement in vision (+ 8 ETDRS letters, p = 0.006) and decreased retinal thickness (158 µm, p = 0.00003) with aflibercept treatment at month 24.
conclusionsThe 2-year results of the NEWTON study demonstrated the sustained benefits of a TAE dosing regimen with aflibercept in patients with chronic CRVOs. The visual acuity gains and anatomic improvements observed at year one were maintained through month 24 with less visits and treatments. This may help minimize the treatment burden in patients with recurrent macular edema secondary to non-ischemic CRVO.
