Evaluation of Relapse Presence in Multiple Sclerosis
Evaluation of Relapse Presence in Multiple Sclerosis Patients by Cross-Sectional In-Vivo Corneal Confocal Microscopy
Purpose: This study aims to investigate the demonstrability of increased inflammation and neurodegeneration in multiple sclerosis (MS) patients in relapse period compared to MS patients in remission by cross-sectional analysis of in-vivo corneal confocal microscopy (IVCM), and to evaluate the alternations with a second IVCM administered at least 6 months after the relapse period.
Methods: This prospective, non-randomized-controlled, cross-sectional study included 58 MS patients which were grouped regarding the presence of relapse (MS-Relapse group [n=27] and MS-Control group [n=31]), and age-sex matched 30 healthy controls (HC). The corneal nerve fiber density (CNFD), the corneal nerve branch density (CNBD), the corneal nerve fiber length (CNFL), and dendritic cell (DC) density were evaluated in all MS patients and HCs by IVCM. If the patients in the MS-relapse group did not have an attack within 6 months, the same parameters were evaluated with the second IVCM. The patients with a history of optic neuritis or trigeminal symptoms were excluded.

MS-Relapse
Twenty-seven patients (MS-Relapse) for whom the administration of intravenous corticosteroids was decided due to the diagnosis of new relapse. The diagnosis of RRMS and the new relapse was confirmed and decided by a senior neurologist (K.A) of Marmara University Department of Neurology, according to the revised McDonald criteria, based on clinical and radiological findings These subjects underwent Corneal Confocal Microscopy (IVCM). |
All study subjects underwent IVCM (Rostock Cornea Module, Heidelberg Retinal Tomograph III; Heidelberg Engineering, Germany).
Before the examination, two drops of topical anesthetic with proparacaine hydrochloride (Alcaine 0.5%, Alcon-Couvreur, Belgium) were applied to both eyes.
A carbomer-based gel (Viscotears 0.2%; Dr. Gerhard Mann, Chem.-
Pharm.
Fabrik, Germany) was used as the coupling agent between the cornea and the applanating cap of IVCM.
For correctly positioning the central cornea, all subjects were asked to fixate a determined fixation point and controlled with the device camera.
All scans were performed in approximately 5 minutes for each eye by a single experienced ophthalmologist, masked from the subject's disease status.
