Sağlıklı Çocuklarda İki Ayrı Fotorefraktör Cihazının Skiaskopi Ölçümleri ile Karşılaştırılması.

Objective: Comparing refractive values determined by two photorefractory devices (Plusoptix® A09, GmbH, Nuremberg, Germany and SureSight®, Welch Allyn Co, New York, USA) with refractive values obtained by skiascope after cycloplegia with 1% cyclopentolate hydrochloride in healthy children. Methods: Cases aged between 48 and 132 months were evaluated for this cross-sectional study. Cases with no ophthalmic pathology in both eyes and uncorrected visual acuity of 1.0 were included in the study. In all cases, refractive measurements were performed first with Plusoptix® and then with SureSight®. After providing cycloplegia with 1% cyclopentolate hydrochloride, skiascopy was performed. The correlation between the measurements obtained was evaluated with the Pearson correlation coefficient, and the compatibility was evaluated with the Bland-Altman analysis. Results: The mean spherical values of 52 subjects measured by cycloplegic skiascopy, Plusoptix® and SureSight® were 0.88±2.07 dioptry (D), 0.69±1.78D and 1.64±1.06D, respectively; mean of cylindrical measurements are -0.73±0.68D, -0.92±0.67D and -0.83±0.70D, respectively. Comparing Plusoptix® with skiascopy, SureSight® with skiascopy, Plusoptix® with SureSight® measurements, a high positive correlation was found between spherical values (r=0.861, r=0.736, r=0.721, respectively); a positive correlation was also found between cylindrical values (r=0.602, r=0.675, r=0.901, respectively). Skiascopic spherical and cylindrical measurements with Plusoptix®, and skiascopic spherical and cylindrical measurements with SureSight® were found to be compatible with each other (within 95% confidence interval, lower limit: -2.65, upper limit: 1.89; lower limit: -1.35, upper limit: 0.95; lower limit: -3.56, upper limit: 2.06; lower limit: -1.20, upper limit: 0.98). Spherical and cylindrical measurements obtained with Plusoptix® and SureSight® were found to be consistent with each other (within 95% confidence interval, lower limit: -3.39, upper limit: 1.49; lower limit: -0.67, upper limit: 0.51). Conclusion: It was concluded that the results of these three measurements in childhood were compatible with each other. [ABSTRACT FROM AUTHOR]
