Pulsed synchrony regulation of intraocular and cerebrospinal fluid pressure: a novel paradigm for glaucoma pathogenesis and treatment.

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
Glaucoma, the leading cause of irreversible blindness worldwide, is characterized by the progressive loss of retinal ganglion cells (RGCs) and their axons. While elevated intraocular pressure (IOP) is a core risk factor, the pathogenesis of normal-tension glaucoma (NTG) remains unclear, as static IOP is within the normal range. Based on circadian fluctuations of IOP and cerebrospinal fluid pressure (CSFP), and the pressure-dependent function of the ocular glymphatic system, we propose the "dynamic trans-lamina cribrosa pressure difference (TLCPD) imbalance" hypothesis. This hypothesis posits that optic nerve damage may stem from abnormal pulse synchrony between IOP and CSFP (phase mismatch, amplitude mismatch, or abnormal frequency) rather than static TLCPD elevation alone, pending further validation. Dynamic imbalance induces RGC injury through dual mechanisms: mechanical stress on the lamina cribrosa (collagen fiber rupture, astrocyte activation) and metabolic dysfunction (ocular glymphatic clearance impairment, toxic waste accumulation), which ultimately converge on the activation of the programmed axonal degeneration (PAD) pathway-a conserved final common effector of RGC axon loss. Phase mismatch is the core pathological pattern in NTG. In contrast, high-tension primary open-angle glaucoma (POAG) is characterized mainly by amplitude mismatch and abnormal frequency, with potential coexistence and mutual influence of these mechanisms. Verifiable clinical (24-h IOP-CSFP synchronous monitoring) and animal experiments are proposed. This hypothesis may help explain unresolved clinical phenomena, provides novel diagnostic markers (a transient peak in TLCPD) and therapeutic strategies (CSFP regulation, glymphatic function enhancement, modulation of the PAD pathway), and opens new avenues for personalized glaucoma management.
