Summary
Persistent visual complaints (PVCs) affect over a third of multiple sclerosis (MS) patients, often stemming from optic nerve damage or eye movement issues, impacting daily life quality.
Area of Science:
- Neuro-ophthalmology
- Clinical Neurology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease.
- Visual disturbances are common symptoms in MS patients.
- Persistent visual complaints (PVCs) can significantly impact quality of life.
Purpose of the Study:
- To determine the prevalence of PVCs in MS patients.
- To investigate the underlying mechanisms of PVCs.
- To assess the functional disability resulting from PVCs.
Main Methods:
- Prevalence of PVCs assessed in 303 MS patients.
- Comparison of MS-related data between patients with and without PVCs.
- Neuro-ophthalmologic assessment and quality of life questionnaire (NEI-VFQ-25) administered to 70 PVC patients.
Main Results:
- PVCs reported in 34.6% of MS patients.
- PVC patients more frequently had primary progressive MS and neuro-ophthalmologic relapses.
- Afferent visual and ocular-motor pathway dysfunctions were common, linked to optic neuropathy and internuclear ophthalmoplegia; poor NEI-VFQ-25 scores correlated with test impairments.
Conclusions:
- High prevalence of PVCs in MS patients confirmed.
- Persistent optic neuropathy is a notable cause of PVCs in progressive MS.
- Ocular motor dysfunctions contribute to visual disability in daily life for MS patients.

Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
