Detecting Alzheimer's Disease Using Ocular Tissue and Imaging: What Do We Know?
Review in Biomolecules, 2025. 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
Alzheimer's disease (AD) is a progressive neurodegenerative condition with increasing global prevalence. As early diagnosis becomes critical for timely symptomatic management, noninvasive and easily accessible biomarkers are needed. Given the shared embryologic origins between the eye and the brain, ocular imaging has emerged as a promising diagnostic technique. This review summarizes the associations between AD, ocular imaging and fluid biomarkers in the anterior and posterior segment. We also describe the underlying pathophysiology that explains the connections between each ocular structure and the brain in the context of AD. Optical coherence tomography (OCT), OCT angiography, and fundus photography are the most common imaging modalities utilized in AD research. However, these techniques may or may not be feasible in primary care or neurologic clinical settings. Compared to plasma biomarker analysis, which is minimally invasive and nearing clinical implementation, ocular biomarkers remain primarily valuable in research investigations.
