Risk of Scar in the Comparison of Age-related Macular Degeneration Treatments Trials
Open accessAbstract
Objective To describe risk factors for scar in eyes treated with ranibizumab or bevacizumab for neovascular age-related macular degeneration (AMD). Design Prospective cohort study within a randomized clinical trial. Participants Patients with no scar on color fundus photography (CFP) or fluorescein angiography (FA) at enrollment in the Comparison of Age-related Macular Degeneration Treatments Trials (CATT). Methods Eyes were assigned to ranibizumab or bevacizumab treatment and to 1 of 3 dosing regimens for 2 years. Masked readers assessed CFP and FA. Baseline demographic characteristics, visual acuity, morphologic features on photography and optical coherence tomography (OCT), and genotypes associated with AMD risk were evaluated as risk factors using adjusted hazard ratios (aHRs) and associated 95% confidence intervals (CIs). Scars were classified as fibrotic with well-demarcated elevated mounds of yellowish white tissue or nonfibrotic with discrete flat areas of hyperpigmentation with varying amounts of central depigmentation. Main outcome measures Scar formation. Results Scar developed in 480 of 1059 eyes (45.3%) by 2 years. Baseline characteristics associated with greater risk of scarring were predominantly classic choroidal neovascularization (CNV) (aHR, 3.1; CI, 2.4-3.9) versus occult CNV, blocked fluorescence (aHR, 1.4; CI, 1.1-1.8), foveal retinal thickness >212 μm (aHR, 2.4; CI, 1.7-3.6) versus <120 μm, foveal subretinal tissue complex thickness >275 μm (aHR, 2.4; CI, 1.7-3.6) versus ≤75 μm, foveal subretinal fluid (aHR, 1.5; CI, 1.1-2.0) versus no subretinal fluid, and subretinal hyperreflective material (SHRM) (aHR, 1.7; CI, 1.3-2.3) versus no SHRM. Eyes with elevation of the retinal pigment epithelium had lower risk (aHR, 0.6; CI, 0.5-0.8) versus no elevation. Drug, dosing regimen, and genotype had no statistically significant association with scarring. Fibrotic scars developed in 24.7% of eyes, and nonfibrotic scars developed in 20.6% of eyes. Baseline risk factors for the scar types were similar except that eyes with larger lesion size or visual acuity <20/40 were more likely to develop fibrotic scars. Conclusions Approximately half of eyes enrolled in CATT developed scar by 2 years. Eyes with classic neovascularization, a thicker retina, and more fluid or material under the foveal center of the retina are more likely to develop scar.

The Results (Correlation of Morphology with VA; page not supplied) report substantially worse visual acuity at 52 weeks in eyes with intraretinal fluid. They report little impact on mean visual acuity from subretinal or sub-RPE fluid at that time, matching the attributed finding. (LLM, conf=0.91)

The Results report that eyes with foveal scar had the lowest mean visual acuity and that scar developed in 18.6% of eyes after 52 weeks of anti-VEGF treatment (page not available in our copy). The Discussion describes fibrosis as a treatment-emergent adverse effect associated with the greatest reduction in visual acuity. These passages support the vision-loss association, but do not establish scarring as a natural outcome of untreated neovascular AMD. (LLM, conf=0.84)

A conclusion the paper draws from its own results — it cites no other source for it, so there is none to check. The quote shows it is in the paper.
In the paper
“It is possible that with a longer period of observation, subretinal fluid also could affect visual acuity through scar formation.”

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The cited source says what the claim attributes to it.
In the citing paper
“We had shown earlier that during the first two years of treatment of nAMD with anti-VEGF drugs, the risk factors present at baseline for developing a scar included predominantly classic type of CNV, blocked fluorescence, thicker retina, larger foveal subretinal tissue complex thickness, foveal subretinal fluid and subretinal hyperreflective material.16”

“For example, in one retrospective study, progressive visual acuity loss occurred in 41 eyes of 40 patients with subfoveal subretinal hemorrhage that comprised more than 50% of the CNV lesion.(36) In that report, it was not clear whether the scar formation was directly a result of the more extensive hemorrhage.”

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.
A language model drew the claims from the paper on 2026-09-29, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-09-29 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
