Normative data for macular perimetry using the MP-3 microperimeter in healthy individuals.
Article in Arquivos brasileiros de oftalmologia, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeMicroperimetry has been used for several years as a form of visual function testing in patients with retinal diseases. Normal microperimetry values obtained with microperimeter MP-3 have not yet been fully published, and baseline values for topographic macular sensitivity and correlations with age and sex are needed to establish degrees of impairment. This study aimed to determine values for light sensitivity thresholds and fixation stability using the MP-3 in healthy individuals.
methodsThirty-seven healthy volunteers (age, 28-68 years), underwent full-threshold microperimetry using a 4-2 (fast) staircase strategy with the standard Goldmann III stimulus size and 68 test points positioned identically to those in the Humphrey Field Analyzer 10-2 test grid. The fixation stability was simultaneously recorded during the microperimetry test. The relationship between global sensitivity and age was calculated using linear regression analysis.
resultsMicroperimetry was performed on 37 participants (74 eyes). The global mean sensitivity was 29.01 ± 1.44 (range, 26-31) dB. The mean central sensitivity at 2° measured by the MP-3 was 28.5 ± 1.77 dB in the right eye (OD) and 28.75 ± 1.98 dB in the left eye (OS). The total median fixation stability values within 2° and 4° were 80% and 96%, respectively. The linear regression analysis also revealed an age-related global sensitivity decline per year of -0.051 dB ± 0.018 (OD) and -0.078 dB ± 0.021 (OS).
conclusionsMicroperimetry performed with the MP-3 allows for an automatic, accurate, and topography-specific examination of retinal sensitivity thresholds. The results of this study provide a normal and age-matched database of MP-3 microperimetry.
