What is Optic Neuritis as First Presentation of MS?

Optic neuritis is acute demyelinating inflammation of the optic nerve causing rapidly progressive vision loss in one eye over hours to days, with pain on eye movement, color desaturation, and a relative afferent pupillary defect.

MRI of the brain and orbits with contrast demonstrates optic nerve enhancement and quantifies central nervous system lesion burden — multiple T2 lesions strongly increase the risk of conversion to multiple sclerosis.

Acute treatment is high-dose intravenous methylprednisolone, which speeds visual recovery; long-term prognosis depends on timely initiation of disease-modifying therapy in patients with high MS conversion risk.

Symptoms

Acute monocular vision loss
Pain on eye movement
Color desaturation
Central scotoma
Uhthoff phenomenon (heat-related blur)

Risk Factors

Female sex, age 20-40
Family history of MS
Vitamin D deficiency
Smoking
Prior demyelinating events

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Sudden vision loss in one eye
  • Pain with eye movement
  • New double vision
  • Numbness or weakness elsewhere
  • Bowel/bladder dysfunction

Treatment Methods

01
MRI brain and orbits with contrast
02
Lumbar puncture with oligoclonal bands
03
Aquaporin-4 and MOG antibody testing
04
IV methylprednisolone 1 g for 3-5 days
05
Disease-modifying therapy initiation
06
Neurology and neuro-ophthalmology follow-up

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
