| Title | Novel OCT Finding of Retinal Vasculitis Associated with Multiple Sclerosis |
| Accept poster if oral is not possible ? | No |
| Purpose | To report a new optical coherence tomography (OCT) finding of retinal vasculitis associated with multiple sclerosis. |
| Methods | This study was a prospective observational analysis of all cases of retinal vasculitis associated with multiple sclerosis (MS). All patients underwent OCT scans in the areas showing clinically evident retinal vasculitis "sheathing." |
| Results | A total of 12 patients (24 eyes) diagnosed with retinal periphlebitis associated with MS were included in the study. For comparison, 16 patients (24 eyes) with non-MS retinal vasculitis were also included. The non-MS vasculitis diagnoses consisted of 4 patients (6 eyes) with Behçet's disease, 2 patients (4 eyes) with sarcoidosis, 3 patients (3 eyes) with vasculitis secondary to tuberculosis, 2 patients (2 eyes) with toxoplasmosis, 1 patient (1 eye) with syphilis, and 4 patients (8 eyes) with idiopathic vasculitis. OCT scans revealed that all cases of periphlebitis associated with MS (100%) exhibited hyperreflective tissue facing the vitreous cavity in the areas affected by clinically apparent vascular sheathing. This specific finding was absent in all non-MS-related vasculitis cases. |
| Conclusion | OCT provides novel findings of hyperreflective tissue facing the vitreous cavity over the periphlebitis area in all MS cases. This suggests that OCT may be an important non-invasive tool for suspecting MS in patients with retinal vasculitis. Further future studies are warranted to confirm this finding and its association. |
