Accidental macular injury from short-term exposure to a handheld high-intensity LED light.

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
Objective: To report a case of macular injury caused by short-term exposure to a handheld high-intensity light emitting diode (LED) light. Design: Interventional case report. Participant: A patient with macular injury caused by short-term exposure to the light of a handheld high-intensity LED device. Intervention: The patient was examined and followed for 3 months after exposure with ophthalmologic examinations (including funduscopy, optical coherence tomography [OCT], fluorescein angiography [FA], and multifocal electroretinography [mfERG]). The injured eye was treated with one retrobulbar injection of 20 mg triamcinolone acetonide at 5 days after exposure. Main outcome measures: Visual acuity, ophthalmoscopic, and OCT findings. Results: 3 days after exposure, the best corrected visual acuity (BCVA) of the right eye was 6/20. OCT revealed the acute stage of the injury with eminence of the retinal pigment epithelium (RPE). BCVA was improved to 16/20 and 20/20 at 19 and 33 days after exposure, respectively. OCT results of follow-ups at five days, 19 days, 33 days and 3 months after exposure have demonstrated the restoration process of the injury. Conclusions: Short-term exposure to high-intensity LED light may cause damage to the retina. As the expansion of LED use in modern life, education and supervision are of urgent need for public health.
