Trabecular meshwork motion reduces in eyes with normal tension glaucoma using phase-sensitive optical coherence tomography.

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 investigate alteration in pulsatile trabecular meshwork (TM) motion in normal tension glaucoma (NTG) compared with healthy controls and primary open-angle glaucoma (POAG) patients.
methodsThis cross-sectional study included 15 healthy individuals, 14 NTG patients and 15 POAG patients with asymmetric visual field defects (VFD). Eyes were categorised as mild-to-moderate VFD (GI) or severe VFD (GII). A custom-designed phase-sensitive optical coherence tomography system was used to assess TM motion in temporal and nasal regions. Parameters analysed included maximum velocity (MV) and cumulative displacement (CDisp).
resultsMean deviation was comparable between NTG and POAG in GI eyes (p=0.944), and intraocular pressure post-treatment in POAG was similar to NTG (p=0.066). MV and CDisp in NTG were significantly lower than in healthy controls (p<0.001) but higher than in POAG (p<0.001). In POAG, temporal MV, nasal CDisp and temporal CDisp were significantly higher in GI than in GII eyes (p=0.002, 0.025 and 0.038). In NTG, no significant differences in MV or CDisp were observed between GI and GII eyes (p>0.05).
conclusionsPulsatile TM motion is reduced in NTG compared with healthy individuals but remains higher than in POAG. Unlike POAG, NTG shows no asymmetry in TM motion between eyes with varying VFD severity, suggesting additional factors beyond TM biomechanics contribute to NTG progression.
