Ocular Misalignment and Motility Limitation in Orbital Tumors.
About 29% of orbital tumor patients had limited eye movement in the affected eye.
Ocular Misalignment and Motility Limitation in Orbital Tumors.
To predict prognosis and aid in the treatment of residual strabismus/ocular misalignment by analyzing the pattern of ocular motility disturbances caused by orbital tumors, and investigating factors associated with the severity of misalignment or motility limitation.
The medical records of 63 patients diagnosed with orbital tumors were retrospectively reviewed.
eye movement was restricted on the tumor side, not the normal eye
Twelve patients had orbital tumors situated in the extraconal space (60%), while the other 8 patients (40%) had lesions in the intraconal space.
The mean size of extraconal tumors was significantly larger than intraconal tumors ( p = 0.010), and there were no significant differences in tumor size between every four groups.
Compared with the normal fellow eye, significant limitations of ocular motility were observed in adduction ( p = 0.043) and supraduction ( p = 0.002).
The size of intraconal tumors was the only significant factor related to ocular motility limitation ( p = 0.010).
Ocular motility limitations were more common with large extraconal tumors, mostly in the direction of the adjacent extraocular muscle.
In contrast, ocular motility was limited toward the opposite direction of the nearest extraocular muscle with intraconal tumors. Tumor size in the intraconal space was the only significant factor associated with ocular motility impairment.
