What Is Eales Disease?
Eales disease, also known as Eales retinopathy, is an uncommon retinal condition characterised by inflammation around the peripheral retinal veins. It primarily affects young adults and can lead to reduced blood flow to parts of the retina, abnormal blood vessel growth and bleeding inside the eye.
As the condition progresses, areas of the retina may receive insufficient oxygen, encouraging the growth of fragile new blood vessels. These vessels can bleed into the vitreous, the clear gel inside the eye, causing blurred vision or sudden vision loss.
Early diagnosis and regular retinal monitoring are important to identify complications and protect remaining vision.
Common Symptoms of Eales Disease
Symptoms of Eales disease may vary depending on the stage and severity of retinal involvement. Common warning signs include:
Floaters: Small spots, threads or shadows drifting across the field of vision.
Blurred vision: Reduced clarity that may occur as the condition progresses.
Sudden vision loss: May occur when bleeding develops inside the vitreous.
Peripheral retinal changes: Areas of reduced retinal blood supply may develop, sometimes before noticeable symptoms.
Recurrent vitreous haemorrhage: Repeated bleeding can cause episodes of visual disturbance or vision loss.
Some patients may initially have few symptoms. Retinal examination is therefore important when Eales disease is suspected.
What Causes Eales Disease?
The exact cause of Eales disease is not fully understood. It is generally described as an idiopathic occlusive retinal periphlebitis, meaning inflammation affects the veins in the peripheral retina and the precise cause is not always identified.
The condition may progress through several stages:
Retinal periphlebitis: Inflammation develops around peripheral retinal veins.
Capillary non-perfusion: Some areas of the retina receive inadequate blood supply.
Neovascularisation: Fragile new blood vessels grow in response to retinal ischaemia.
Vitreous haemorrhage: Abnormal vessels may bleed into the vitreous.
Tractional complications: In advanced cases, scar tissue may pull on the retina and threaten vision.
Other causes of retinal vasculitis and vascular occlusion must be considered before confirming the diagnosis. Tuberculosis may be associated with some cases, but this does not mean every patient with Eales disease has ocular tuberculosis.
How Is Eales Disease Diagnosed?
Eales disease is a diagnosis of exclusion. An eye specialist must assess the retinal findings and rule out other conditions that can produce similar inflammation, retinal ischaemia or bleeding.
Depending on the patient's presentation, investigations may include:
Dilated retinal examination.
Fundus photography to document retinal changes.
Fluorescein angiography to identify leakage, non-perfusion and abnormal blood vessels.
Optical coherence tomography (OCT) to assess the macula and detect swelling.
Additional laboratory tests or investigations for infections and systemic inflammatory conditions when clinically indicated.
An accurate diagnosis helps determine whether the condition is active, stable or associated with complications requiring urgent treatment.
Conventional Treatment for Eales Disease
Treatment depends on the stage of the disease and the presence of inflammation, retinal ischaemia, abnormal blood vessels, bleeding or traction.
Observation and Monitoring
Some cases may be monitored closely when there is no active sight-threatening complication. Regular retinal examinations help identify changes that may require treatment.
Anti-inflammatory Treatment
When active inflammation is present, an ophthalmologist may consider anti-inflammatory treatment after relevant infections have been evaluated and excluded or appropriately addressed.
Retinal Laser Treatment
Laser photocoagulation may be recommended for areas of retinal ischaemia to reduce the stimulus for abnormal blood vessel growth and lower the risk of further bleeding.
Anti-VEGF Injections
In selected cases, injections that inhibit vascular endothelial growth factor (VEGF) may be used to manage abnormal blood vessel growth. Their suitability depends on the retinal findings and overall treatment plan.
Vitrectomy
Surgery called vitrectomy may be necessary when vitreous haemorrhage persists or when tractional complications threaten the retina.
Timely ophthalmic treatment is essential when sight-threatening complications develop. Complementary care should never delay indicated laser treatment, injections or surgery.
Ayurvedic Supportive Care at Sanjeevan Netralaya, Hyderabad
At Sanjeevan Netralaya, Ayurvedic supportive care may be considered alongside appropriate ophthalmic management, with attention to the patient's diagnosis, disease activity, retinal structure and remaining functional vision.
The supportive-care approach may focus on:
Remaining visual function: Understanding the central and peripheral vision that remains.
Practical visual needs: Addressing everyday difficulties involving contrast, object recognition, reading and mobility.
Overall wellbeing: Considering nutrition, sleep, blood pressure, diabetes and other relevant health factors.
Individualised supportive measures: Discussing appropriate supportive care based on the patient's condition and medical history.
Continued monitoring: Encouraging regular retinal follow-up and awareness of warning symptoms.
Ayurvedic supportive care has not been established as a treatment that reverses retinal ischaemia, eliminates abnormal retinal blood vessels or restores retinal tissue that has been permanently damaged. It should complement, not replace, specialist-directed treatment.
What Results Can Patients Expect?
Outcomes depend on the extent of retinal inflammation, the amount of ischaemia, the presence of abnormal blood vessels, episodes of bleeding and whether the macula has been affected.
Where permanent damage remains, care may focus on making the best use of existing vision. Depending on individual needs, low-vision aids and rehabilitation may help with reading, recognising faces, identifying objects and moving around safely.
Results vary between individuals, and improvements cannot be guaranteed. The priority is to control active disease, address complications promptly and preserve remaining vision wherever possible.
Why Choose Sanjeevan Netralaya?
Sanjeevan Netralaya offers a retina- and optic-nerve-focused supportive-care perspective, emphasising:
Nearly 30 years of experience, as stated by the centre.
Individualised assessment based on diagnosis, disease stage and clinical findings.
Attention to remaining functional vision and practical daily needs.
Consideration of overall health alongside appropriate ophthalmic treatment.
Realistic expectations and continued medical monitoring.
For Eales disease, specialist retinal evaluation remains essential, particularly when active inflammation, retinal ischaemia or vitreous haemorrhage is present.
When Should You Seek Urgent Eye Care?
Seek urgent retinal evaluation if you experience sudden vision loss, a sudden increase in floaters, flashes of light, a dark curtain across your vision or rapidly worsening eyesight.
These symptoms may indicate bleeding, retinal detachment or another sight-threatening complication. Do not delay medical assessment while exploring complementary therapies.
Conclusion
Eales disease is an uncommon retinal condition that can progress from inflammation of peripheral retinal veins to reduced blood supply, abnormal blood vessel growth and recurrent vitreous haemorrhage.
Early diagnosis, appropriate stage-specific treatment and regular retinal monitoring are important for protecting vision. At Sanjeevan Netralaya, Hyderabad, Ayurvedic supportive care may be considered as part of an individualised approach alongside appropriate ophthalmic management, with realistic goals based on the patient's condition and remaining vision.
