Short answer · Medically reviewed summary · Last updated: 2026-05-08
Eales Disease is a rare, idiopathic inflammatory condition primarily affecting the peripheral retina, characterized by recurring retinal hemorrhages and vascular inflammation. It typically presents in young adults and can lead to vision loss if the resulting complications, such as retinal detachment or neovascularization, are not managed by a retina specialist. What is the pathophysiology of Eales Disease? The exact cause of Eales Disease remains unknown, though it is widely considered an immune-mediated vasculitis.

What is Eales Disease? Plain-language, medically reviewed definition plus the lived reality told by patients.
Eales Disease is a rare, idiopathic inflammatory condition primarily affecting the peripheral retina, characterized by recurring retinal hemorrhages and vascular inflammation. It typically presents in young adults and can lead to vision loss if the resulting complications, such as retinal detachment or neovascularization, are not managed by a retina specialist.
What is the pathophysiology of Eales Disease?
The exact cause of Eales Disease remains unknown, though it is widely considered an immune-mediated vasculitis. The condition progresses through three distinct clinical stages: inflammation (periphlebitis), ischemia (capillary non-perfusion), and proliferation (neovascularization). Unlike other retinopathies, Eales Disease is uniquely defined by its peripheral location and the absence of systemic vascular diseases like diabetes or hypertension.
Who is typically affected by Eales Disease?
Eales Disease predominantly affects healthy young males, typically between the ages of 20 and 40. While it was historically reported most frequently in the Indian subcontinent, cases have been documented globally. At DiseaseMaps.org, 23 community members are currently navigating their journey with this condition, highlighting the importance of shared experiences in managing this rare diagnosis.
What are the primary clinical features?
Patients with Eales Disease often notice "floaters" or sudden blurred vision caused by vitreous hemorrhage. Key clinical features include:
- Peripheral periphlebitis: Inflammation of the retinal veins.
- Retinal ischemia: Areas of the retina lacking adequate blood supply.
- Neovascularization: The growth of fragile new blood vessels that are prone to bleeding.
- Vitreous hemorrhage: Bleeding into the gel-like substance of the eye.
How is Eales Disease differentiated from other conditions?
It is critical to distinguish Eales Disease from other inflammatory retinal conditions like sarcoidosis, Behçet’s disease, and ocular tuberculosis. A diagnosis of Eales Disease is essentially a diagnosis of exclusion, meaning clinicians must perform systemic testing to rule out these other infectious or inflammatory triggers before confirming the diagnosis.
Next steps
- Consult a retina specialist for a comprehensive dilated eye exam and fundus fluorescein angiography.
- Discuss potential systemic workups to rule out underlying inflammatory or infectious conditions.

- Monitor for sudden changes in vision and seek immediate care if new "floaters" or vision loss occur.
