Eye position of orthophoric patients in awakened state was evaluated under general anesthesia to determine the anatomical position of rest. METHODS: About 25 to 30 minutes after induction of general anesthesia, we measured the amount of eye deviation at 30 cm and 1 m by Krimsky method in 143 orthophoric patients who had no neurological disorder, limitation of eye movement or previous history of extraocular muscle surgery. RESULTS: Of the 143 patients, 54(37.8%) were male and 89(62.2%) were female. Under general anesthesia, eye position checked at 30 cm was 20.9+/-7.8D divergent and eye position at 1 m was 20.6+/-7.7D divergent. Checked at 30 cm, male patients demonstrated 20.1+/-6.6D of divergence and female patients, 21.3+/-8.4D of divergence. Checked at 1 m, eye position was 20.0+/-6.5D divergent in male and 21.0+/-8.4D divergent in female. The differences between sexes and between ages were not significant(p>0.05). CONCLUSIONS: The orthophoric patients in awakened state demonstrated 20.9+/-7.8D of divergence at 30 cm, 20.6+/-7.7D of divergence at 1 m under general anesthesia. And these results show the anatomical position of rest in orthophoric subjects.
