Sir,We thank the authors for their interest and contribution in our recent study.[1] In our study, preoperative and postoperative measurements of palpebral fissure, margin reflex distance 1–2, lower lid function, Hertel value, lower lid crease were evaluated. Aiming to optimize reliability of the measurements, the same examiner performed the measurements and only cooperative patients were included. These measurements were taken twice, and the average value was used for statistical analysis. The authors offered us to evaluate all parameters with intraclass correlation coefficient (ICC) which is used as an indicator for reproducibility of repeated measurements.[2] According to authors’ request, we have evaluated ICC for our measurements as shown in Table 1. We have observed significantly high reproducibility between measurements, except for postoperative margin reflex distance-2. Using standard preoperative and postoperative photographs might help to increase reliability and reproducibility; however, the cooperation of the patients, particularly children, still would be a limitation for such measurements.
