Which are the symptoms of Eales Disease?

Eales Disease is a rare, idiopathic inflammatory retinal vasculopathy that primarily causes peripheral retinal periphlebitis, leading to recurrent vitreous hemorrhages and vision loss. Common symptoms include the sudden onset of "floaters," blurred vision, and dark spots in the visual field, typically affecting young, otherwise healthy adults.

What are the primary symptoms of Eales Disease?

The clinical presentation of Eales Disease is typically bilateral, though it may be asymmetric. The condition often progresses through three stages: inflammation, ischemia, and neovascularization. Patients frequently report the following clinical manifestations:

• Sudden onset of floaters: Often described as "cobwebs" or dark spots caused by blood leaking into the vitreous humor.


• Blurred or decreased vision: Resulting from vitreous hemorrhage or macular edema.


• Peripheral vision loss: Caused by progressive retinal ischemia and peripheral vascular occlusion.


• Photopsia: Flashes of light that may precede a significant hemorrhage.

How do symptoms progress in Eales Disease?

Eales Disease symptoms often follow a cyclical pattern of quiet periods punctuated by acute episodes of vitreous hemorrhage. In the early stages, patients may be asymptomatic while peripheral periphlebitis develops. As the condition advances, venous sheathing and capillary non-perfusion become more pronounced. Over time, the growth of abnormal new blood vessels (neovascularization) significantly increases the risk of severe, vision-threatening complications like tractional retinal detachment.

Which symptoms impact daily quality of life?

The most debilitating aspect of Eales Disease is the unpredictable nature of vitreous hemorrhages, which can cause sudden, dramatic drops in visual acuity. This volatility often leads to anxiety and limitations in driving, reading, and performing professional duties. Among the 23 community members on DiseaseMaps.org, many report that the emotional toll of managing recurrent flare-ups is as challenging as the physical vision changes.

When should I seek immediate medical attention?

If you have been diagnosed with or suspect Eales Disease, seek an urgent evaluation by a retina specialist if you experience a sudden increase in floaters, a "curtain" falling over your vision, or a rapid, painless decline in visual acuity. These can be signs of a new vitreous hemorrhage or an impending retinal detachment.

Next steps

• Schedule a comprehensive dilated fundus examination with a vitreoretinal specialist.


• Monitor your vision daily using an Amsler grid to detect subtle changes.


• Connect with the 23 members of the Eales Disease community on DiseaseMaps.org to share experiences.


• Discuss potential treatment options, such as laser photocoagulation or anti-VEGF injections, with your ophthalmologist.
