8.The exophthalmic coefficient (EOC) was calculated according to GOP and the area of eyeball and front orbit.The normal reference value was 7.50~11.00 for male and 6.30~10.88 for female. 眼球大小与眼眶前部容积之比值与眼球斜向突出度有直线相关关系,由此计算出眼球突出系数,正常参考值:男7.50~11.00,女6.30~10.88。
Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor). Complete or partial dislocation from the orbit is also possible from trauma or swelling of surrounding tissue resulting from trauma.
