Functional and Anatomical Changes of Acute Solar Retinopathy Investigated With Electroretinography and Optical Coherence Tomography: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The purpose of this case is to illustrate how early electroretinography (ERG) can be used to investigate functional macular changes caused by acute solar retinopathy. This is a case report of a 44-year-old woman who presented on April 12, 2024 with acute solar retinopathy after viewing the solar eclipse on April 8, 2024 without wearing solar viewing glasses. The patient's best corrected visual acuity (BCVA) was 20/800 OU. Yellow macular lesions were seen on fundoscopy bilaterally. Spectral domain optical coherence tomography (SD-OCT, Spectralis; Heidelberg Engineering, Heidelberg, Germany) revealed bilateral foveal hyperreflectivity of the outer retina with attenuation of the external limiting membrane, ellipsoid zone, and retinal pigment epithelium (RPE) interdigitation line. Early ERG was performed to determine retinal function. Full field ERG (ffERG) demonstrated normal generalized retinal function OU; however, multifocal ERG (mfERG) showed bilateral macular dysfunction primarily affecting the foveal and parafoveal regions. These findings persisted at the two-month follow-up with no significant improvement in the BCVA. Acute solar retinopathy presents with anatomical changes to the retinal layers, particularly photoreceptors. Damage and disruption to photoreceptors can result in consequent apoptosis and atrophy that can be seen on fundoscopy and OCT imaging. Measures of retinal function, such as ERG, can be used in determining baseline and progression of visual function. Additionally, this case illustrates the importance of public health measures to educate the general population about the dangers of sungazing.
