Mesopic Microperimetry Captures Extensive Macular Atrophy with Pseudodrusen-Like Appearance Progression Beyond Visual Acuity: A Longitudinal Analysis.

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
Purpose: To quantify longitudinal changes in mesopic and scotopic retinal sensitivity (RS) and evaluate their relationship with retinal pigment epithelium (RPE) atrophy progression and foveal involvement in extensive macular atrophy with pseudodrusen-like appearance (EMAP). Design: Retrospective longitudinal observational study. Participants: One hundred twenty-eight eyes from 66 patients with clinically confirmed EMAP followed at a tertiary inherited retinal diseases clinic. Methods: Eyes with ≥1 visit including mesopic and red scotopic microperimetry using a validated 20-stimulus grid and multimodal imaging (blue autofluorescence and spectral-domain OCT) were included. Associations between square root-transformed RPE atrophy size and functional metrics (best-corrected visual acuity [BCVA], mesopic RS [mRS], and scotopic RS [sRS]) were analyzed using mixed-effects models adjusted for age and intereye correlation. Longitudinal rates of functional and structural change were estimated in eyes with ≥2 visits. Cox proportional hazards regression evaluated predictors of foveal involvement. Main Outcome Measures: Structure-function relationships, yearly rates of functional decline, and predictors of foveal involvement. Results: Among 128 eyes (median age, 59.5 years; 69.7% female), larger RPE atrophy size was significantly associated with worse BCVA, mRS, and sRS (all Conclusions: In EMAP, mRS demonstrated stronger structure-function associations with RPE atrophy and a more consistent longitudinal decline than BCVA and sRS. Decline in macular mRS independently predicted subsequent foveal involvement, supporting microperimetry as a sensitive functional endpoint for patient stratification and interventional trials.
