AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

Objective: To discuss the methods and items for clinical linear accelerator (Clinac) and 3D treatment planning system (TPS)/intensity modulated radiotherapy(IMRT) system based on 2D ionization chambers array(2D-ICA). Methods: The 2D-I-CA laid on the anthropomorphic phantom with five centimeters and which was put on another five centimeters same phantom.All data have gained as following conditions: the SAD is 100 cm and the SSD is 90 cm; the fields' size are 2 cm, 5 cm, 10 cm,15 cm ,20 cm respectively and 2 cm×10 cm ,5 cm×20 cm ,20 cm×5 cm, MU=100 cGy;the Clinae and TPS were verified by some special items for checking their dose accuracy, such as, square fields, rectangular fields, and rectangular fields with 600 wedge or 300 wedge, which were measured for verification their flatness and symmetry. And some measured items were only for checking multileaf collimator (MLC) and TPS calculated accuracy. So, we developed moveable MLC fields and IMRT plans and compound fields to evaluate leafs side effects and leafs end effects and transmission effects. Results: The flatness value of square and rectangular fields was 100.07%~102.66%,and their symmetry value was 0.10%~1.49%; and these irradiate fields' size were compared with light fields' sizes, which the X direction deviation was-1.5%~0.7% ,the Y direction deviation was-1.4%~1.0%,and their average value was-0.47%.To verify calculated data for TPS ,we developed Gamma value and ab-solute value (<4%)to evaluate their accuracy. For square and rect-angular fields, The Gamma value was 92.02%~96.35%.In com-pound fields Which were composed with two half fields (X1 = 5 cm, X2 =0 cm, Y= 10 cm and X1 = 0 cm,X2 = 5 cm, Y=10 cm),the maximum deviation was about 5%.And five fields (2 cm×10 cm) composed one fields (10 cm×10 cm),the maximum deviation was about 10% in the joint place. The Gamma value of one fields was 96.6%, another was 93.2% in the moveable fields. Conclusions: To dollop 2D ionization chambers array to verify the dose for Clinac and TPS, it was so quick and simple, and it was important that it bring more accurate dose evaluation and more clinical quality assurance and quality control methods.
