Which condition involves inflammation of the optic nerve and can be associated with multiple sclerosis?

• A. Optic Neuritis
• B. Sarcoidosis
• C. Retinal Vascular Occlusion
• D. Premature Baby

Answer: (A)

Optic neuritis is inflammation of the optic nerve and is a classic cause of acute, painful vision loss in one eye. The pain is often worse with eye movement, and patients typically notice reduced color vision and an afferent pupillary defect on exam. This condition is closely linked to multiple sclerosis because MS is a demyelinating disease that frequently affects the optic nerve; optic neuritis can be the first sign of MS or occur during the disease course. MRI of the brain may reveal demyelinating plaques, supporting the MS association, and treatment with high-dose IV corticosteroids can speed recovery, though it doesn’t necessarily change the long-term risk of developing MS. Other options don’t fit as well because: sarcoidosis can involve the optic nerve but is a systemic granulomatous disease and not defined by its strong link to MS; retinal vascular occlusion affects the retina itself, causing sudden vision loss without optic nerve inflammation; premature baby refers to retinopathy of prematurity in infants, a retinal vascular disorder not involving inflammatory optic nerve disease.
