Comparison of Rebound and Applanation Tonometry in Eyes With Focal Corneal Edema.
Article in Veterinary ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveTo determine the effect of corneal edema on intraocular pressure (IOP) readings and their accuracy and precision when obtained with handheld rebound and applanation tonometers. ANIMALS AND PROCEDURES: IOP readings from areas of focal corneal edema were compared to those from clear cornea in 10 eyes of 7 glaucomatous cats in vivo using TONOVET Plus (TVP) and TONOVET (TV01) rebound, and Tono-Pen Vet (TP) applanation tonometers. Four different feline eyes with focal corneal edema were cannulated ex vivo and tonometry readings obtained from clear and edematous cornea at set manometric IOPs from 5 to 70 mmHg.
resultsRebound tonometry values were 4.0 ± 5.5 (SD) mmHg lower, and TP values were 13.0 ± 5.9 (SD) mmHg higher in regions of edema versus clear cornea in the same eye (p = 0.0075). Relative to manometry, TVP and TV01 accuracy and precision were acceptable for clear cornea readings but were negatively impacted by corneal edema. TP-derived readings grossly underestimated high IOPs relative to manometry in both clear and edematous feline cornea and were significantly less accurate than rebound tonometers in clear cornea (p = 0.03). All tonometers were less precise in edematous cornea; the TP was significantly less precise than the TV01 (p = 0.0419).
conclusionsAlthough IOP values obtained with the TVP and TV01 tend to be less accurate and precise in edematous versus clear cornea, rebound tonometry is impacted by corneal edema to a lesser degree than applanation tonometry. In patients with corneal edema, IOP measurements should be obtained from clear corneal regions when possible.
