Introduction:

Elevated Episcleral Venous Pressure (EVP) is a condition where the pressure within the veins in the episcleral tissue, which surrounds the sclera (the white part of the eye), is higher than normal. This comprehensive article aims to explore the causes, symptoms, diagnosis, and management of Elevated Episcleral Venous Pressure.

Causes of Elevated EVP:

Elevated EVP can result from various underlying conditions, including:

• Orbital Venous Malformations: Abnormalities in the orbital veins can lead to increased venous pressure in the episcleral tissue.
• Cavernous Sinus Fistula: An abnormal connection between the arteries and veins in the cavernous sinus can cause increased blood flow and pressure in the episcleral veins.
• Orbital Tumors: Certain tumors in the orbit can compress the veins, leading to elevated EVP.
• Carotid-Cavernous Fistula: An abnormal connection between the carotid artery and cavernous sinus can also cause elevated EVP.

Symptoms of Elevated EVP:

The clinical manifestations of Elevated EVP may include:

• Proptosis: Bulging of the eyeball due to increased pressure within the eye socket.
• Episcleral Venous Engorgement: Visible dilation and engorgement of the episcleral veins.
• Conjunctival Injection: Redness and engorgement of the conjunctival blood vessels.
• Decreased Visual Acuity: In severe cases, elevated EVP can lead to reduced visual acuity.
• Ocular Discomfort: Patients may experience a sensation of fullness or pressure in the eye.

Diagnosis and Evaluation:

Diagnosing Elevated EVP involves a comprehensive ophthalmic examination and may include:

• Slit-Lamp Biomicroscopy: Visualization of the episcleral veins and conjunctival engorgement.
• Ocular Ultrasonography: This imaging technique can provide valuable information about orbital and vascular abnormalities.
• Venous Pressure Measurements: Direct measurements of venous pressure using manometry can be performed in some cases.

Management of Elevated EVP:

The management of Elevated EVP depends on the underlying cause and the severity of symptoms. Treatment options may include:

• Observation: Asymptomatic cases or those with mild symptoms may be monitored without intervention.
• Medical Management: Managing conditions such as hypertension can help reduce episcleral venous pressure.
• Interventional Radiology: In some cases, interventional radiological procedures may be used to treat vascular malformations or fistulas.
• Surgical Procedures: Surgical options, like embolization or decompression, may be considered to relieve venous pressure.

Conclusion:

Elevated Episcleral Venous Pressure is a condition characterized by increased pressure within the veins of the episcleral tissue. It can be caused by various underlying factors and may lead to visual disturbances and ocular discomfort. Early diagnosis and appropriate management are essential to prevent potential complications and preserve visual function.
