Abstract
Background: Myopia is one of the common Refractive Visual Errors (RVE) that produces musckeloskeltal complaines, such as stiffness, fatigue and muscular pain in the neck which in turn may affect cervical curvature and range of motion.
Aim of Study: To investigate the relationship between refractive visual errors subjects and cervical curvature and cervical range of motion.
Patients: Fifty participants 15-30 years old from Kasr Al-Aini Hospital in October 2016. They assigned in two equal groups refractive myopic and normal sighted).
Methods: Cervical Range of Motion (CROM) was assessed by using O.B gonyometer, cervical angles (OC-C2, C1-C2, C2-C7) were measures by using corel draw program in X-ray.
Results: Comparison between groups revealed no signif-icant different in OC-C1 and a significant different in C1-C2 and C2-C7, additionally there was a significant difference in flexion, extension, Rt. and Lt. rotation (p=0.007, 0.01, 0.0001, 0.001) between groups respectively, there was no significant correlation between right and left eye and cervical angles and range of ROM.
Conclusion: Myopia causes changes in cervical curve and ROM but the degree of Myopia is not correlated to this changes of cervical curve and ROM.
