We thank the authors for their interest in our work and the relevant points brought up for discussion. With regard to the sequence of visual field testing, in the African Descent and Glaucoma Evaluation Study (ADAGES) visual field testing order (24-2 vs 10-2) was assigned randomly at the patient level. The median time between visual field examinations was 20 minutes (25th to 75th quartile range, 16 –28). As the authors suggested, it is therefore, possible participants were fatigued by the time they performed the second test, whether it was a 24-2 or 10-2 examination.
