Reply to Comment on: Evaluating Goldmann Applanation Tonometry Intraocular Pressure Measurement Agreement Between Ophthalmic Technicians and Physicians

We appreciate the thoughtful comments of Dr. Shu and associates. The authors raise the concern that circadian rhythm may have partly contributed to the differences in intraocular pressure (IOP) when comparing clinicians to technicians. While it is theoretically possible, we doubt that this would have been the case in the present study as patients were evaluated by physicians within a short time of being screened by technicians. Although we did not collect data for the exact amount of time elapsed between IOP measurements taken by the technician and those taken by the physician, the longest it would have been was an hour, and most subjects would have been seen within minutes.
