Visual Loss after Scoliosis Surgery: What Do Surgeons and Patients Need to Know? Three Case Reports.
Article in Revista brasileira de ortopedia, 2024. 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
Visual deficit after spinal surgery is rare but tragic. The main causes include external eye injury, cortical blindness, central retinal artery occlusion, and ischemic optic neuropathy. In scoliosis surgery, this complication potentially arises from prolonged surgical time, high blood loss, prone position, hydroelectrolytic imbalance, and cerebrospinal fluid loss. In 849 scoliosis correction surgeries, 3 patients developed postoperative visual deficits: 2 achieved complete visual acuity recovery, but 1 remained with partial sequelae. There are four causes of postoperative amaurosis: ischemic optic neuropathy, central retinal artery occlusion, external eye injury, and cortical blindness. Since the prevention of this complication cannot be assured, it is essential to explain the risk of visual deficits to patients undergoing scoliosis surgery, who must sign the informed consent form. Visual loss after spinal surgery for scoliosis correction is a rare but severe and, sometimes, irreversible complication. The surgical team must know about this possibility in order to adopt preventive measures and reduce its incidence.
