Early diagnosis of ocular motility alteration in Autoimmune Thyroid Ophthalmopathy (TAO)

Purpose Object of our study is early diagnosis, through EOMG exam, of ocular motility alterations in subjects aff ected by TAO without clinical evidences. Methods 40 eyes of 20 patients aff ected by TAO without clinical evidences were examinated. All the patients were submitted to ocular motility exam and EOMG exam. Results were related with a group of 46 eyes of 23 subjects with same age and sex without ocular motility alterations and not aff ected by TAO. We used BM6000MOE system and WinEOMG software for signal stimulation and acquisition, WinElabEOMG software for results elaboration. Results In 15% of observed patients we found an increase of movement speed dissinergy; in 60% of patients we found an increase of movement maximal speed; in 45% we found a decrease of movement medium speed. Conclusion In TAO aff ected patients without evident ocular clinical signs, the analysis with EOMG sistem could bring an ocular motility alteration predictive value.
