Emerging microfluidic diagnostic systems for anterior segment diseases: a systematic review.
Review in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2026. 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
purposeTo evaluate emerging microfluidic diagnostic systems for anterior segment ocular diseases, emphasizing translational diagnostic relevance, clinical innovation, and current limitations.
methodsThis systematic review followed the PRISMA guidelines. A comprehensive PubMed search was conducted for studies assessing microfluidic diagnostic systems applied to anterior segment diseases, including ectatic corneal disorders, dry eye and tear-film abnormalities, infectious keratitis, and glaucoma, up to September 09, 2025. Methodological quality was assessed using the Standards for Reporting of Diagnostic Accuracy Studies (STARD) framework.
resultsThe literature search identified 228 publications, of which 11 studies met inclusion criteria after screening and quality assessment. In ectatic corneal diseases, cornea-on-a-chip models reproduced multilayer corneal architecture under dynamic conditions, enabling quantitative assessment of wound healing, barrier function, and biomechanical responses. For dry eye and tear-film disorders, paper-based and wearable microfluidic platforms enabled objective microliter-scale tear analysis, with electrochemical sensing demonstrating strong correlation with conventional measurement methods (R² ≥0.99) and reduced analytical costs. In infectious keratitis, integrated microfluidic real-time polymerase chain reaction (RT-PCR) systems achieved rapid multiplex pathogen detection with markedly shortened diagnostic times compared with culture methods. In glaucoma, implantable and wearable microfluidic sensors enabled continuous intraocular pressure monitoring with detection limits near 1 mm Hg and strong agreement with reference methods (R²>0.99), although some systems required individual calibration (R²≈0.78).
conclusionsMicrofluidic technologies provide a rapid, low-cost, and minimally invasive approach for real-time physiological assessment in anterior segment diagnostics and represent a promising strategy for earlier detection and more personalized, evidence-based ophthalmic care.
