Study to Assess OCT: RNFL and GCL in MS Patients

Multiple Sclerosis Clinical Trial

Official title: Prospective Cross Sectional Study To Assess The Clinical Utility of Optical Coherence Tomography to Measure Axonal Degeneration of the Optic Nerve, in a Cohort of 200 Subjects Meeting the Diagnostics Criteria of Multiple Sclerosis

Status Completed

Clinical Trial Summary

The purpose of this study is to collect preliminary data on retinal nerve fiber layer and ganglion cell layer damage in multiple sclerosis (MS) patients, using optical coherence tomography (OCT). For this study the Zeiss Cirrus OCT Imaging System will be used. The same system will be used consistently for the duration of the study.

Clinical Trial Description

Hypothesis: Multiple sclerosis results in axonal degeneration which can be assessed objectively and non-invasively by serial OCT measurements of the RNFL and GCL.

This will be a prospective cross-sectional, non-interventional study; total recruitment will be 200 subjects. Recruitment will be stratified to enroll at least 50 subjects currently taking Lemtrada and 50 subjects with a documented diagnosis of ON. The study will enroll subjects primarily from practices in the Tampa Bay Area and adjacent counties. It is a planned non-interventional study; subjects will be followed by their neurologist and the study ophthalmologist and will receive standard of care. All subjects will have the ophthalmological examination and diagnostic measures, by the Principal Investigator, Dr. Grace Levy-Clarke, at Tampa Bay Uveitis Center.

Study Duration: The study duration will be 24 months, with an interim analysis at 50% recruitment status.

There are two primary aims of this longitudinal observational study:

1. To determine whether atrophy within specific retinal layers over time is associated with clinical neurological progression of MS

2. To determine whether an ON history affects the relationship described in aim # 1

Eye Exam: Subject will have an eye exam, including:

Visual Acuity Testing Color Vision Testing Automated perimetry/Peripheral Vision Testing Completing the National Eye Institute Visual Functioning Questionnaire (NEI/VFQ) Slit Lamp Examination Measurement of Intraocular Pressure (IOP) Dilated Fundus Examination (Ophthalmoscopy) Fundus Photography Optical Coherence Tomography: RNFL and Macular OCT

Neurologic Assessments: Must be performed no more than 60 days prior to screening/assessment Day 0 Ophthalmic Assessments ;
