Abstract

Purpose To estimate the incidence, size, and growth rate of geographic atrophy (GA) during 5 years of follow-up among participants in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT).Design Cohort within a clinical trial.Participants Participants included in CATT.Methods A total of 1185 CATT participants were randomly assigned to ranibizumab or bevacizumab treatment and to 3 treatment regimens. Participants were released from protocol treatment at 2 years and examined at approximately 5 years (N = 647). Two masked graders assessed the presence and size of GA in digital color photographs (CPs) and fluorescein angiograms (FAs) taken at baseline and years 1, 2, and 5. Cox proportional hazard models were used to identify risk factors for incidence of GA. Annual change in the square root of the total area of GA was the measure of growth. Multivariate linear mixed models including baseline demographic, treatment, and ocular characteristics on CP/FA and optical coherence tomography (OCT) as candidate risk factors were used to estimate adjusted growth rates, standard errors (SEs), and 95% confidence intervals (CIs).Main outcome measures Geographic atrophy incidence and growth rate.Results Among the 1011 participants who did not have GA at baseline and had follow-up images gradable for GA, the cumulative incidence was 12% at 1 year, 17% at 2 years, and 38% at 5 years. At baseline, older age, hypercholesterolemia, worse visual acuity, larger choroidal neovascularization (CNV) area, retinal angiomatous proliferation (RAP) lesion, GA in the fellow eye, and intraretinal fluid were associated with a higher risk of incident GA. Thicker subretinal tissue complex and presence of subretinal fluid were associated with less GA development. The overall GA growth rate was 0.33 mm/year (SE, 0.02 mm/year). Eyes treated with ranibizumab in the first 2 years of the clinical trial had a higher growth rate than eyes treated with bevacizumab (adjusted growth rate, 0.38 vs. 0.28 mm/year; P = 0.009). Geographic atrophy in the fellow eye, hemorrhage, and absence of sub-retinal pigment epithelium fluid at baseline were associated with a higher growth rate.Conclusions Development of GA is common 5 years after initiating therapy. Several risk factors identified at 2 years of follow-up persist at 5 years of follow-up.

  • Long-term follow-up of geographic atrophy after anti-VEGF therapy has been reported, but long-term follow-up of scars after anti-VEGF initiation has received little attention.

    “While long-term follow up of geographic atrophy after anti-VEGF therapy, more recently referred to as macular atrophy, has been described, long term follow-up of scars after the initiation of anti-VEGF therapy has not received much attention.10,11”

    From Development and Course of Scars in the Comparison of Age-Related Macular Degeneration Treatments Trials (2018) · cites this paper as [11]

    The Introduction and Discussion describe five-year follow-up of geographic atrophy in participants treated with anti-VEGF therapy, supporting the first part of the sentence. The cited paper does not assess long-term scar follow-up or state that it has received little attention, so it does not support that part. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
