Long-term outcomes of the observe-and-plan regimen in treating neovascular age-related macular degeneration: a retrospective real-life analysis.
Article in Eye (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
objectivesThis study aimed to evaluate the long-term (7 years) outcome of visual acuity in patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) agents following the observe-and-plan regimen. SUBJECTS/
methodsA total of 195 eyes from 181 patients with nAMD (mean age 79.5 ± 6.9 years), with a mean follow-up duration of 66 ± 37 months, treated with intravitreal anti-VEGF (ranibizumab or aflibercept) were included in this retrospective study. The principles of the observe-and-plan regimen were followed, with follow-up exceeding 3 years in real-life settings. Data collected included visual acuity (VA), number of injections and visits, central retinal thickness, and any complications over 7 years from baseline.
resultsThe mean baseline VA was 63 ± 17 Early Treatment of Diabetic Retinopathy Study letters (Snellen equivalent 20/63), improving to 73 ± 14 at year 1. The initial visual gain was slightly reduced with a final mean VA of 70 ± 18 letters (Snellen equivalent 20/40) at year 7. The mean central macular thickness decreased significantly from 375 ± 129 at baseline to 276 ± 75 at year 1 and to 279 ± 87 at year 7. The mean annual number of injections decreased from 8.7 ± 3.2 in year 1 to 6.7 ± 3.7 in year 2 and to 5.5 ± 2.8 in year 7. The mean annual number of visits remained constant throughout, with 4.1 ± 1.3 visits in year 1 and 4.7 ± 1.7 in year 7.
conclusionsThe observe-and-plan regimen was very efficient for treating nAMD in real-life settings, reducing the clinical burden on the medical system and patients, with excellent functional and structural long-term results.
