What is Endoscopic Optic Nerve Decompression?

Endoscopic optic nerve decompression is performed by accessing the medial wall of the optic canal through the sphenoid sinus and posterior ethmoid; the bony portion of the canal is thinned with a diamond burr and removed to relieve pressure on the optic nerve.

Main indications include traumatic optic neuropathy, fibrous dysplasia involving the optic canal, and compressive optic neuropathy in thyroid orbitopathy. Selected cases may also include optic nerve sheath meningioma and idiopathic intracranial hypertension.

Avoidance of open craniotomy results in low morbidity and short recovery; outcomes depend strongly on prompt intervention, often within 7 days for traumatic cases, before irreversible optic atrophy develops.

Symptoms

Sudden or progressive vision loss
Color vision loss
Relative afferent pupillary defect (RAPD)
Visual field defect
Optic disc edema or pallor
Post-traumatic visual decline

Risk Factors

Head trauma
Facial bone fractures
Fibrous dysplasia
Thyroid orbitopathy
Optic nerve sheath meningioma
Sphenoid sinus pathology

When to See a Doctor?

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

  • If vision declines after trauma
  • If RAPD is detected
  • If a visual field defect is documented
  • If there is no response to steroid therapy
  • If compressive pathology is shown radiologically

Treatment Methods

01

02
MRI and high-resolution CT
03
Endoscopic sphenoethmoidectomy
04

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.
