Abstract
Objective To observe the stereoscopic vision changes in patients with orbital blowout fracture at early stage.Methods The orbital volume and enophthalmos were measured and calculated with CT measurements and computer software in 28 patients of orbital blowout fracture.The stereoscopic vision of them were examined with stereogram designed by YAN Shao-ming and synoptophone Ⅲ.Results The orbital volume on the damaged side was bigger than the undamaged side.The increase in the amount of orbital volume was positively correlated with amount of eyeball wall invagination.The stereoscopic vision of patients of orbital blowout fracture at early stage would decline at different degrees.Conclusion The extra attention should be paid to the changes of stereopsis during the treatment of orbital blowout fracture.Besides endophthalmos and diplopia,the changes of stereopsis should be one of the indicators for surgeries.
