Visual impairment certification secondary to ARMD in Leeds, 2005–2010: is the incidence falling?
Open accessAbstract
Aim The aim of this study was to evaluate trends in visual impairment certification due to age-related macular degeneration (ARMD) in the Leeds metropolitan area between 2005 and 2010.Methods In this retrospective study, the primary causes of visual impairment certification in the Leeds metropolitan area between 2005 and 2010 were reviewed. ARMD was considered to be the cause of certification when recorded as the primary factor contributing to visual impairment in one or both eyes. The incidence of visual impairment certification due to ARMD was calculated using population estimates from the Office of National Statistics.Results ARMD was the primary cause of visual impairment certification in all study years, accounting for 58.7 and 50.8% of certifications in 2005 and 2010, respectively. For the same period, the incidence of certification due to ARMD fell from 364 to 248 per million population per year. This was largely the result of a fall in the incidence of visual impairment certification due to neovascular ARMD from 225 to 137 per million population per year, beginning in 2008 after the introduction of a local commissioning policy on the use of intra-vitreal ranibizumab.Conclusion The incidence of visual impairment certification due to ARMD in the Leeds metropolitan area appears to be falling. This is largely the result of a decrease in certification secondary to neovascular ARMD. This represents a change in the previously described trend for ARMD visual impairment certification.

Anti-VEGF therapies have substantially reduced severe visual loss and disability from neovascular age-related macular degeneration at the population level in several developed economies.
“The introduction of anti-vascular endothelial growth factor (anti-VEGF) has made significant impact on the reduction of the visual loss due to neovascular age-related macular degeneration (n-AMD).”
From Defining response to anti-VEGF therapies in neovascular AMD (2015) · cites this paper as [3]
The Abstract and Discussion report that certification for visual impairment due to neovascular ARMD fell in Leeds after ranibizumab was introduced. But the Discussion explicitly says the study cannot determine whether treatment caused the decrease, and the Conclusion calls for research on its relevance to larger populations. The paper therefore does not establish a treatment-driven reduction across several developed economies. (LLM, conf=0.88)
Experimental — accuracy not yet measuredThe overall effectiveness of anti-VEGF therapies in n-AMD is unquestionable.
“The overall effectiveness of anti-VEGF therapies in n-AMD is unquestionable.”
From Defining response to anti-VEGF therapies in neovascular AMD (2015) · cites this paper as [3]
The Introduction says ranibizumab stabilises visual acuity in the majority of neovascular ARMD cases. However, the paper addresses one anti-VEGF treatment rather than therapies overall, and the Discussion says it cannot determine whether the decline in certifications was a direct consequence of its introduction. The claim’s unqualified certainty goes beyond the source. (LLM, conf=0.86)

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.
