Development and Course of Scars in the Comparison of Age-Related Macular Degeneration Treatments Trials
Open accessAbstract
Purpose To describe risk factors for scar formation and changes to fibrotic scar through 5 years in the Comparison of Age-related Macular Degeneration Treatments Trials (CATT). Design Multicenter, prospective cohort study. Participants A total of 1061 subjects in CATT. Methods Color photographic and fluorescein angiographic images from baseline and 1, 2, and 5 years were evaluated. Incidence of scar formation was estimated with Kaplan-Meier curves. Risk factors were assessed with Cox regression models. Main outcome measures Scar formation, fibrotic scar area, and macular atrophy associated with fibrotic scar ("atrophy"). Results Cumulative proportion of eyes with scar was 32%, 46%, and 56% at years 1, 2, and 5, respectively. Baseline factors associated with increased risk (adjusted hazards ratio [aHR] and 95% confidence interval [CI]) were classic choroidal neovascularization (CNV) (aHR, 4.49; 95% CI, 3.34-6.04) versus occult, hemorrhage >1 disc area (DA) (aHR, 2.28; 95% CI, 1.49-3.47) versus no hemorrhage, retinal thickness >212 μm (aHR, 2.58; 95% CI, 1.69-3.94) versus <120 μm, subretinal tissue complex thickness >275 μm (aHR, 2.64; 95% CI, 1.81-3.84) versus ≤75 μm, subretinal fluid thickness >25 μm (aHR, 1.31; 95% CI, 0.97-1.75) versus no fluid, visual acuity (VA) in fellow eye 20/20 (aHR, 1.72; 95% CI, 1.25-2.36) versus 20/50 or worse, retinal pigment epithelium elevation absence (aHR, 1.71; 95% CI, 1.21-2.41), and subretinal hyperreflective material (aHR, 1.72; 95% CI, 1.25-2.36). Among 68 eyes that developed fibrotic scar at year 1, VA decreased by a mean of additional 13 letters between years 1 and 5. Mean scar area was 1.2, 1.2, and 1.9 DA at 1, 2, and 5 years, respectively. Atrophy was present in 18%, 24%, and 54% of these eyes at years 1, 2, and 5, respectively; the mean areas were 1.6, 2.0, and 3.1 DA, respectively. Atrophy replaced fibrotic scar in 8 eyes at year 5. There was no significant correlation between scar growth and atrophy growth. The rate of growth for both was similar between the clinical trial and observation periods. Conclusions Several morphologic features, including classic CNV and large hemorrhage, are associated with scar formation. Rate of new scar formation declined after 2 years. Most fibrotic scars and accompanying macular atrophy expanded over time, reducing VA.

In the 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”

The Results section identifies each listed baseline feature as a predictor of scarring in the multivariate final model, including predominantly classic CNV, blocked fluorescence, greater retinal and subretinal tissue complex thickness, foveal subretinal fluid, and subretinal hyperreflective material. The Results also specify that scar development was assessed after two years of anti-VEGF therapy. (LLM, conf=0.94)

The Discussion reports that fibrosis (scarring) and atrophy strongly influenced visual function, more than blood or exudate. But Subjects and Methods says the measurements were taken at baseline, when none of the patients had received interventional therapy to the presenting eye. This paper therefore does not support the claim about patients treated with anti-VEGF injections. (LLM, conf=0.90)

The Discussion (page unavailable) identifies foveal scar and foveal geographic atrophy among the features associated with the largest decreases in visual acuity in CATT. It also names several other features in that group, so it does not establish atrophy and scar as the two foremost outcomes. (LLM, conf=0.84)

The Study Design section says lesions containing blood were permitted up to a total size of 12 optic-disk areas, but it gives no limit on hemorrhage as a proportion of the lesion. Searches for hemorrhage, blood, and an exclusion threshold did not find a passage establishing that patients whose hemorrhage exceeded half the lesion were excluded. (LLM, conf=0.73)

The Study Design section requires neovascularization to compose at least 50% of the entire lesion. That eligibility rule supports the claim for this trial: hemorrhage could not occupy more than half of the lesion. The paper does not establish the criteria of the other trials cited alongside it.

The Rate of expansion section reports that 9 of 20 eyes had a follow-up review within two years of atrophy onset, leaving 11 without a review in that interval. But it describes those visits as follow-up after atrophy began to be measured, not as the start of measurement. The claim therefore confuses follow-up timing with when measurements commenced.

The Discussion (page unavailable) proposes that some RPE cells transdifferentiate, acquire new behaviors, and may contribute to loss of the pigmented cell layer in atrophy. It does not identify a mesenchymal phenotype or say that these cells adhere to and exert traction on the extracellular matrix, nor does it establish that mechanism as a contributor to clinical atrophy progression.

Neither section says that RPE cells adhere to and exert traction on the extracellular matrix or that such forces contribute to clinical atrophy progression. (LLM, conf=0.84)

The Abstract reports geographic atrophy during at least 3.5 years of follow-up after anti-VEGF initiation and says that little information was available on sight-threatening conditions beyond 3.5 years. It does not specifically assess how much attention long-term scar follow-up had received; it reports five cases of atrophic disciform scars but does not establish the claim about the literature on scars.

- Checkable: passes — It can be checked against evidence.
- Load-bearing: passes — The paper’s conclusions depend on it.
- Based: passes — The paper gives a reason why it holds.
It may state two separate claims as one.
Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Even with optimal adherence, anti-VEGFs’ effectiveness can subside in nAMD patients, owing to underlying pathological changes occurring over time, leading to further vision loss [71, 72].”

Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
§ Development and Course of Scars in the Comparison of Age-related Macular Degenerations Treatments Trials (CATT) > Abstract > Results
“visual acuity in fellow eye 20/20 (1.72, 95% CI 1.25, 2.36) vs 20/50 or worse”
§ Development and Course of Scars in the Comparison of Age-related Macular Degenerations Treatments Trials (CATT) > Results
“Good baseline visual acuity (20/20 or above) in the fellow eye was associated with increased risk of developing scar in the study eye (aHR 1.34, 95% CI 1.00, 1.74, p=0.04) compared to visual acuity of 20/50 or worse.”

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.
