Oct-A and Perimetry in Multiple Sclerosis

Not Yet RecruitingN/A

Sponsor: Assiut University

Conditions: Multiple Sclerosis

Interventions: optical coherence tomography angiography, Visual Field Perimetry

This study aims to assess retinal vascular density using OCT-A and correlate these parameters with visual field changes in MS patients with and without a history of ON

Eligibility overview

Sex: ALL

Healthy volunteers: Yes

Study type: OBSERVATIONAL

Eligibility criteria

Inclusion Criteria:

* Diagnosis of relapsing-remitting multiple sclerosis (RR-MS) or other MS subtypes confirmed by established neurological criteria. .Ability to undergo OCTA imaging and visual field testing. .Visual acuity sufficient to perform reliable visual field testing.
* Absence of other ocular diseases affecting the retina or optic nerve (e.g., diabetic retinopathy, glaucoma)

Exclusion Criteria:

.History of ocular diseases unrelated to MS that could confound OCTA or visual field results.

.Recent optic neuritis episode within a defined period (often 3-6 months) to avoid acute inflammation effects.

.Media opacities preventing quality OCTA imaging. .Systemic diseases that may affect retinal vasculature (e.g., uncontrolled hypertension, diabetes).

.Poor cooperation or inability to complete visual field testing reliably
