Causes & Risk Factors
Several factors can contribute to Eales Disease.
The exact cause of Eales disease remains one of medicine's ongoing mysteries, though researchers have identified several likely contributing factors.
The exact cause of Eales disease remains one of medicine's ongoing mysteries, though researchers have identified several likely contributing factors. The most widely accepted theory suggests that the condition results from an abnormal immune response, where the body's defense system mistakenly attacks the blood vessels in the retina. This autoimmune reaction causes inflammation in the retinal vessels, leading to the characteristic bleeding and vision problems.
Tuberculosis infection has emerged as a significant potential trigger for Eales disease.
Tuberculosis infection has emerged as a significant potential trigger for Eales disease. Many patients with this eye condition show evidence of previous or current tuberculosis exposure, even when they don't have active lung disease. The theory suggests that proteins from tuberculosis bacteria may trigger an immune response that cross-reacts with retinal blood vessels, causing the inflammatory damage seen in Eales disease.
Other factors that may contribute to the development of this condition include viral infections, hormonal changes, and genetic predisposition.
Other factors that may contribute to the development of this condition include viral infections, hormonal changes, and genetic predisposition. Some researchers have noted that the disease often occurs in areas where tuberculosis is common and nutritional deficiencies are prevalent. Stress, both physical and emotional, may also play a role in triggering episodes, though this connection requires further study. The predominance of cases in young men suggests that hormonal factors, particularly testosterone levels, might influence disease development or progression.
Risk Factors
- Being male between ages 20-40
- Living in or traveling to areas with high tuberculosis rates
- History of tuberculosis infection or exposure
- South Asian, Middle Eastern, or Mediterranean ancestry
- Compromised immune system function
- Chronic inflammatory conditions
- Smoking tobacco products
- Nutritional deficiencies, particularly vitamin deficiencies
- Family history of autoimmune diseases
- Recent viral or bacterial infections
Diagnosis
How healthcare professionals diagnose Eales Disease:
- 1
Diagnosing Eales disease requires a comprehensive eye examination by an ophthalmologist, as the condition can mimic several other retinal disorders.
Diagnosing Eales disease requires a comprehensive eye examination by an ophthalmologist, as the condition can mimic several other retinal disorders. The diagnostic process typically begins with a detailed medical history, focusing on any recent infections, travel history, and family medical background. Your doctor will ask about specific symptoms like floaters, vision changes, and any previous eye problems.

The cornerstone of diagnosis involves specialized imaging tests that reveal the characteristic changes in retinal blood vessels.
The cornerstone of diagnosis involves specialized imaging tests that reveal the characteristic changes in retinal blood vessels. Fluorescein angiography, where a dye is injected into your arm and photographs are taken as it circulates through the eye's blood vessels, helps identify areas of inflammation, bleeding, or abnormal blood vessel growth. Optical coherence tomography provides detailed cross-sectional images of the retina, showing any swelling or structural changes. Your doctor may also perform electroretinography to assess how well your retina responds to light.

Since tuberculosis may play a role in triggering Eales disease, your doctor will likely order tests to check for TB exposure.
Since tuberculosis may play a role in triggering Eales disease, your doctor will likely order tests to check for TB exposure. These might include a chest X-ray, tuberculin skin test, or blood tests that detect TB infection. Additional blood work may screen for other inflammatory conditions or infections that could cause similar eye problems. The diagnosis often requires ruling out other conditions like diabetic retinopathy, retinal vein occlusion, or other inflammatory eye diseases that can cause similar symptoms.
Complications
- The most serious complications of Eales disease involve progressive damage to the retina and potential permanent vision loss.
- Recurrent bleeding into the eye's interior can cause scar tissue formation, which may pull on the retina and lead to retinal detachment.
- This complication requires immediate surgical intervention to prevent permanent blindness.
- Some patients develop proliferative vitreoretinopathy, where scar tissue continues to grow and contract, making treatment more challenging.
- Other significant complications include the development of new, abnormal blood vessels that grow in response to areas of poor blood flow in the retina.
- These new vessels are fragile and prone to bleeding, creating a cycle of recurrent problems.
- Some people may develop glaucoma as a secondary complication, particularly if repeated bleeding episodes cause increased pressure within the eye.
- With prompt recognition and appropriate treatment, many of these complications can be prevented or successfully managed, emphasizing the importance of regular monitoring and early intervention when problems arise.
Prevention
- Preventing Eales disease proves challenging since its exact cause remains unclear, but several strategies may help reduce risk or prevent recurrences.
- If you live in or plan to travel to areas where tuberculosis is common, taking precautions to avoid TB exposure can be helpful.
- This includes avoiding close contact with people who have active tuberculosis and ensuring good ventilation in crowded spaces.
- Maintaining overall health through good nutrition may play a protective role, particularly ensuring adequate intake of vitamins and minerals that support immune function.
- Some research suggests that nutritional deficiencies might contribute to disease development, so a balanced diet rich in antioxidants and essential nutrients could be beneficial.
- Avoiding smoking is particularly important, as tobacco use can worsen inflammation and interfere with blood vessel health throughout the body, including in the eyes.
- For people already diagnosed with Eales disease, preventing recurrences becomes the primary focus.
- This involves taking prescribed medications consistently, attending regular follow-up appointments with your ophthalmologist, and reporting any new vision changes promptly.
- Managing stress through relaxation techniques, regular exercise, and adequate sleep may help reduce the likelihood of disease flares, though more research is needed to confirm this connection.
Treatment for Eales disease focuses on controlling inflammation, preventing further blood vessel damage, and preserving vision.
Treatment for Eales disease focuses on controlling inflammation, preventing further blood vessel damage, and preserving vision. The approach varies depending on the stage and severity of the condition when diagnosed. In early stages, oral corticosteroids like prednisolone are typically the first line of treatment, helping to reduce inflammation in the retinal blood vessels. These medications can be highly effective in controlling active disease, though they require careful monitoring for side effects, especially with long-term use.
When oral steroids aren't sufficient or cause troublesome side effects, doctors may recommend other anti-inflammatory medications.
When oral steroids aren't sufficient or cause troublesome side effects, doctors may recommend other anti-inflammatory medications. Immunosuppressive drugs like methotrexate or cyclosporine can help control the abnormal immune response that drives the disease. Some patients benefit from injections of corticosteroids directly into the eye, which allows for higher local concentrations of medication while minimizing systemic side effects.
If tuberculosis is suspected as an underlying trigger, treatment with anti-tuberculosis medications may be necessary, even in patients without active lung disease.
If tuberculosis is suspected as an underlying trigger, treatment with anti-tuberculosis medications may be necessary, even in patients without active lung disease. This approach, called anti-tubercular therapy, has shown promise in preventing recurrences of Eales disease. The treatment typically involves a combination of antibiotics taken for several months under close medical supervision.
For advanced cases with complications like retinal detachment or significant bleeding, surgical intervention may be required.
For advanced cases with complications like retinal detachment or significant bleeding, surgical intervention may be required. Vitrectomy, a procedure where the eye's gel-like interior is removed and replaced, can clear blood from the eye and repair retinal damage. Laser photocoagulation may be used to seal leaking blood vessels and prevent further bleeding. Recent research has explored newer treatments like anti-VEGF injections, which help reduce abnormal blood vessel growth and may offer additional options for managing this complex condition.
Living With Eales Disease
Living with Eales disease requires developing a partnership with your healthcare team and learning to monitor your vision carefully. Many people find it helpful to perform simple vision checks at home, such as covering one eye at a time and noting any changes in clarity, new floaters, or areas of vision loss. Keeping a vision diary can help you track patterns and communicate effectively with your doctor about any changes.
