Am J Ophthalmol. 1985 Jun 15;99(6):649-51. doi: 10.1016/s0002-9394(14)76029-5.


Of 54 consecutive infants referred for ophthalmoscopy with the pupils dilated, continuous electrocardiographic monitoring showed that 17 (31%) had bradycardia, ranging from 10% to 59% of baseline, coincident with instillation of eyedrops, insertion of an eyelid speculum, pressure on the globe, or stretching of the medial and lateral recti muscles.
