Abstract
PURPOSE
To evaluate intraoserver and inteobserver repeatability of the "exaggerated forced duction test" or "oblique traction test" and the "excyclo and incyclo passive rotation test" or "cyclorotation traction test".
METHODS
44 eyes of 22 patients were evaluated under deep general anesthesia. Passive duction was tested on supraduction and infraduction by the "exaggerated duction test". The limitation on movement was graduated from 0 to - 4. Passive cyclorotation test was evaluated with retropulsion of the globe until the first resistance is noted. We used the Mendez ring and blue dots marked on the limbus to measure the amount of cyclorotation. The results obtained of excyclo and incyclorotation were recorded. All measurements were made in duplicate for each of the two observers.
RESULTS
The intraclass correlation of the "oblique traction test" coefficient between the two observers was for the IO was 0,738 (95% confidence interval, 0,62-0,83) and 0,910 for the superior oblique (SO) (95% confidence interval, 0,85-0,94). The "cyclorotation traction test" intraclass correlation coefficient of the between the two observers was 0,827 (95% confidence interval, 0,74-0,89) for exclycloduction and 0,792 (95% confidence interval, 0,67-0,85) for inclycloduction. The percentage of patients within 5° of rotation interobserver was 84,1% for excyclorotation and 81,8% for inclyclorotation. Both tests had better correlation on the intraobserver than interobserver evaluation.
CONCLUSIONS
Evaluation of the "oblique traction test" and "cyclorotation traction test" had moderate to good correlation between the two observers and good to excellent on the intraobserver evaluation.
