Our current knowledge of the corneal endothelium in early childhood including its development and response to disease and surgery is suboptimal,13 largely owing to the technical difficulties involved in obtaining specular microscopy (SM) images in very young patients. The gold-standard technique for SM is to acquire images with central fixation while the patient is alert and upright, enabling images of the same corneal region each time. We have modified this technique to capture SM images in children under general anesthesia (GA) who are positioned in the lateral decubitus position with centration of the eye in the display reticle. However, because the patient is not able to fixate on a target, it is not clear whether this acquisition technique is reproducible.
