Introduction:

Eales disease is a rare idiopathic retinal vasculopathy that primarily affects young adults, particularly males. It is characterized by inflammation, occlusion, and neovascularization of the retinal veins, leading to vision loss if left untreated. This comprehensive article aims to provide a thorough understanding of Eales disease, including its causes, symptoms, diagnosis, and treatment options.

Causes and Risk Factors:

The exact cause of Eales disease is unknown, but several factors are believed to contribute to its development, including:

• Vascular inflammation: Inflammation of the retinal blood vessels is thought to play a role in the pathogenesis of Eales disease.
• Genetic predisposition: Certain genetic factors may increase the susceptibility to Eales disease.
• Environmental factors: Exposure to toxins, such as tobacco smoke or infectious agents, has been proposed as potential triggers for Eales disease.
• Immune dysregulation: Abnormal immune responses or autoimmune mechanisms may contribute to the development of Eales disease.

While the exact cause is unclear, Eales disease is believed to result from a complex interplay of these factors.

Symptoms and Clinical Presentation:

The symptoms of Eales disease can vary depending on the stage of the disease but often include:

• Gradual or sudden vision loss, typically affecting one eye initially and potentially progressing to involve both eyes.
• Floaters: Dark spots or specks that float in the field of vision.
• Blurred vision.
• Photopsia: The perception of flashes of light.
• Distorted vision or metamorphopsia.
• Eye pain or discomfort in some cases.

These symptoms may be intermittent or persistent and can significantly impact visual function and quality of life.

Diagnosis and Evaluation:

Diagnosing Eales disease involves a comprehensive evaluation by an ophthalmologist or retina specialist. The following assessments may be performed:

• Medical history and symptom assessment: A detailed history of symptoms, their progression, and associated factors is obtained to establish a clinical picture of Eales disease.
• Visual acuity testing: This evaluates the sharpness of vision using an eye chart to determine the extent of visual impairment.
• Fundus examination: Dilated examination of the retina allows the ophthalmologist to assess the presence of retinal inflammation, vascular changes, and neovascularization.
• Fluorescein angiography: This imaging technique involves the injection of a fluorescent dye into a vein, which allows the ophthalmologist to visualize the retinal blood vessels and identify areas of leakage, occlusion, or abnormal neovascularization.
• Optical coherence tomography (OCT): This non-invasive imaging technique provides detailed cross-sectional images of the retina, helping to assess retinal thickness, fluid accumulation, or structural abnormalities.

Treatment Options:

The management of Eales disease aims to control inflammation, prevent complications, and preserve vision. Treatment options may include:

• Corticosteroids: Oral or intravitreal corticosteroids may be prescribed to reduce retinal inflammation and edema.
• Anti-vascular endothelial growth factor (anti-VEGF) therapy: Intravitreal injections of drugs targeting VEGF, such as bevacizumab or ranibizumab, may be used to inhibit abnormal blood vessel growth and reduce neovascularization.
• Laser photocoagulation: This technique uses a laser to seal leaking blood vessels and destroy abnormal vessels, preventing further bleeding and neovascularization.
• Vitrectomy: In advanced cases with extensive vitreous hemorrhage or tractional retinal detachment, surgical removal of the vitreous gel and repair of retinal abnormalities may be necessary.

The choice of treatment depends on the stage of the disease, extent of retinal involvement, and individual patient factors.

Conclusion:

Eales disease is a rare idiopathic retinal vasculopathy that can cause significant vision loss if left untreated. By understanding its causes, symptoms, diagnosis, and treatment options, healthcare professionals can provide appropriate management strategies to preserve vision and improve the quality of life for individuals with Eales disease.
