Sight-Threatening Immune Retinopathy Developing Secondary to Durvalumab Treatment of Small-Cell Lung Cancer: A Case Report.
Article in Case reports in ophthalmology. 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
Introduction: Given the recent additions of immune checkpoint inhibitors (ICIs) to various cancer treatments, adverse effects, especially involving the eyes, have been on the rise. Here, we report an acute exacerbation of cancer-associated retinopathy (CAR) triggered by durvalumab treatment of small-cell lung cancer (SCLC). Case Presentation: An 81-year-old Asian male complained of a scotoma in the left eye after durvalumab administration, to treat SCLC. Humphrey visual field examination revealed a C-shaped temporal scotoma. Spectralis domain optical coherence tomography revealed outer retinal layer atrophy and progressive loss of the ellipsoid zone in the atrophic peripapillary area. Fundus autofluorescence (AF) images evidenced a large C-shaped hypo-AF with enhanced AF at the margin of the atrophic area, thus at the position of the scotoma. We prescribed subtenon triamcinolone injections under suspicion of CAR exacerbation, supported by positive Western blotting results for Rab6 and aldolase, and immunohistochemical staining of photoreceptor cells. The disrupted ellipsoid zone evident on OCT partially recovered, and a visual field test showed that the scotoma had improved. Conclusion: ICI-triggered exacerbation of CAR should be considered in SCLC patients before ICI treatment commences; an optimal treatment should preserve functional vision.
