Abstract

PURPOSE: There has been a difficulty in measuring angle kappa because special instrument was required. To measure the angle kappa conveniently, we designed a new method using slit lamp biomicroscope.
METHODS
We measured the angle kappa in 124 eyes of 62 patients with newly designed method and compared the measurement by new method with those by T-shape ruler or the major amblyoscope.
RESULTS
We found the average angle kappa was +3.12 degrees by slit lamp, +2.85 degrees by major amblyoscope and +3.04 degrees by T shape ruler method. There was no significant difference between slit lamp and either major amblyoscope method (p=0.48) or T shape ruler (p=0.18).
CONCLUSIONS
The new method of measuring angle kappa using slit lamp biomicroscope seemed to be a convenient and relatively accurate method for measuring of angle kappa and appeared to be beneficial in measurement of ocular deviation.
