Oculocardiac Reflex During Peribulbar Block: A Case Emphasizing the Role of Monitoring in Early Recognition.
Article in Cureus, 2026. 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 oculocardiac reflex is a well-recognized autonomic phenomenon characterized by bradycardia in response to stimulation of ocular structures. It is most frequently encountered during strabismus surgery but may also occur during regional anesthesia techniques such as peribulbar block. We describe the case of a 64-year-old woman with no known comorbidities who developed sudden bradycardia during administration of a peribulbar block for cataract surgery. Following injection of 3 mL of 2% lignocaine with adrenaline (1:200,000) combined with hyaluronidase, a rapid decrease in heart rate (HR) was observed. The injection was immediately discontinued, and the patient was closely monitored. Although atropine was kept ready, it was not administered, as the HR returned spontaneously to baseline within 30 seconds. After confirming hemodynamic stability and adequacy of the block, surgery was completed uneventfully. This case highlights the importance of continuous monitoring and preparedness during a peribulbar block, even in routine clinical settings.
