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.
