Early retinal synaptic dysfunction and proteomic remodeling precede neurodegeneration in a Parkinson's disease model.

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
Parkinson's disease (PD) affects motor and non-motor systems; however, retinal changes and their molecular basis are not well understood. Using a transgenic mouse model overexpressing A53T-mutant human α-synuclein, we examined retinal function, structure, and proteomics at 6- and 16 months. Early retinal dysfunction was detected by a reduction in scotopic oscillatory potential amplitudes on electroretinography. Optical coherence tomography showed early thinning of the retinal nerve fiber layer/ganglion cell layer, and photoreceptor layer, accompanied by thickening of the inner plexiform layer. Phosphorylated α-synuclein accumulation, increased glial fibrillary acidic protein, and loss of the ribbon synapse protein CtBP2 were observed. Proteomic profiling revealed stage-dependent alterations involving α-synuclein, oxidative stress markers, and crystallins. Network analysis showed progression from α-synuclein-associated disruption to inflammation and metabolic remodeling. These results highlight retinal alterations as early indicators of PD neurodegeneration and provide mechanistic insights into the molecular events that precede neuronal loss.
