Disease Details
Family Health Simplified
- Description
- Exudative vitreoretinopathy is a rare genetic disorder affecting the retina, leading to abnormal blood vessel development and potential vision loss.
- Type
- Exudative vitreoretinopathy is typically inherited in an autosomal dominant manner.
- Signs And Symptoms
-
Exudative vitreoretinopathy is an eye disorder that can lead to vision loss. The primary signs and symptoms include:
1. **Vision Problems**: Blurry vision, reduced visual acuity, or vision loss.
2. **Strabismus**: Misalignment of the eyes, commonly known as crossed eyes.
3. **Leukocoria**: A white or yellowish reflection from the retina, often noticeable in photographs.
4. **Nystagmus**: Involuntary, rhythmic eye movements.
5. **Retinal Detachment**: Separation of the retina from its underlying tissue, which can cause flashes of light, floaters, or a shadow over one's field of vision.
6. **Abnormal Blood Vessels**: Improperly formed or leaky retinal blood vessels.
Early diagnosis and treatment are important to prevent severe vision loss or blindness. - Prognosis
- Exudative vitreoretinopathy (EVR) is a genetic disorder affecting the retina, often leading to vision loss. Prognosis varies depending on the severity and promptness of treatment. Some patients maintain functional vision with appropriate medical or surgical interventions, while others may experience progressive deterioration leading to significant visual impairment or blindness. Regular monitoring and early intervention are crucial for better outcomes.
- Onset
- Exudative vitreoretinopathy typically has an onset in early childhood or infancy. It is often identified through genetic screening and clinical symptoms which might include peripheral vision loss, retinal detachment, or other abnormalities in retinal development.
- Prevalence
- The prevalence of exudative vitreoretinopathy is not well-defined in large population studies due to its rarity, but it is considered to be a rare genetic disorder. The exact prevalence is unknown.
- Epidemiology
- Exudative vitreoretinopathy is a rare genetic disorder affecting the retina, leading to abnormal blood vessel development and retinal detachment. Its exact prevalence is not well established due to its rarity, but it is known to follow an autosomal dominant or X-linked inheritance pattern. Genetic mutations in the FZD4, LRP5, and NDP genes have been associated with this condition.
- Intractability
- Exudative vitreoretinopathy is typically considered intractable because it can lead to progressive vision loss and complications despite treatment. Management mainly focuses on slowing disease progression and addressing complications through interventions such as laser therapy, vitrectomy, and other surgical methods. However, complete cure and restoration of normal vision are generally not achievable.
- Disease Severity
- Exudative vitreoretinopathy (EVR) is a rare genetic disorder that affects the retina, the light-sensitive tissue at the back of the eye. Disease severity can vary significantly among individuals. In mild cases, it can cause minimal vision problems, while in severe cases, it can lead to significant vision loss or blindness.

- Pathophysiology
-
Exudative vitreoretinopathy, also known as familial exudative vitreoretinopathy (FEVR), is a genetic disorder affecting the growth and development of the blood vessels in the retina.
Pathophysiology:
FEVR is primarily caused by mutations in several genes, including FZD4, LRP5, NDP, and TSPAN12. These genes are crucial for the Wnt signaling pathway, which is essential for the proper development of retinal vasculature. Defective signaling leads to incomplete or abnormal blood vessel formation in the peripheral retina. This underdeveloped vasculature can result in exudation (fluid leakage), ischemia (restricted blood flow), and subsequent complications like retinal detachment, neovascularization, and tractional retinal folds.

N/A - Carrier Status
-
Exudative vitreoretinopathy (EVR) is a genetic disorder that affects the growth and development of blood vessels in the retina, potentially leading to vision loss. The condition can be inherited in an autosomal dominant or autosomal recessive manner. Carrier status for EVR depends on the specific genetic mutation:
1. **Autosomal Dominant EVR**: If a person carries one copy of the mutated gene, they are typically affected by the disorder. In this case, being a "carrier" usually implies having the condition.
2. **Autosomal Recessive EVR**: If a person carries one copy of the mutated gene, they are a carrier but generally do not exhibit symptoms. Two carriers have a 25% chance with each pregnancy of having an affected child who inherits two copies of the mutated gene.
Carrier testing and genetic counseling can provide more detailed information based on individual circumstances and specific gene mutations involved. - Mechanism
-
Exudative vitreoretinopathy (EVR) is a hereditary disorder characterized by abnormal blood vessel development in the retina, leading to retinal detachment and vision loss.
**Mechanism:**
EVR primarily affects the peripheral retina, causing incomplete or aberrant vascularization. The result is leakage of fluid (exudation), retinal ischemia, and subsequent fibrosis. This leads to traction on the retina, potentially causing retinal detachment.
**Molecular Mechanisms:**
1. **NDP Gene Mutations:** Mutations in the NDP gene, which encodes for the protein Norrin, are commonly implicated in EVR. Norrin is crucial for Wnt signaling pathways, which regulate retinal vascular development.
2. **FZD4 and LRP5 Mutations:** Mutations in the FZD4 and LRP5 genes, encoding for components of the Wnt receptor complex, also disrupt Wnt signaling, affecting vascular development and stability in the retina.
3. **TSPAN12 Gene:** Mutations here can interfere with the Wnt signaling pathway, impacting retinal vascularization.
These genetic mutations disrupt normal signaling pathways necessary for retinal vessel development, leading to the pathological features seen in EVR. - Treatment
- Treatment for exudative vitreoretinopathy typically focuses on managing symptoms and preventing complications. Approaches may include laser photocoagulation to seal retinal tears, cryotherapy to freeze and treat abnormal blood vessels, and surgical interventions like vitrectomy to remove vitreous gel and address retinal detachments. Regular monitoring by an ophthalmologist is essential for early detection and intervention.
- Compassionate Use Treatment
-
Exudative vitreoretinopathy is a rare hereditary disorder that affects the growth and development of the blood vessels in the retina. Compassionate use treatment refers to experimental treatments provided to patients who have no other treatment options. Off-label treatments involve using approved drugs for an unapproved indication based on clinical judgment.
For exudative vitreoretinopathy, potential compassionate use or experimental treatments might include:
1. **Anti-VEGF Agents**: These drugs, although primarily used for conditions like age-related macular degeneration, might be considered to reduce abnormal blood vessel growth and leakage.
2. **Corticosteroids**: Used to reduce inflammation and manage symptoms, though not specifically approved for exudative vitreoretinopathy.
3. **Gene Therapy**: Experimental gene therapies aimed at correcting underlying genetic mutations are in early research stages and may be available through clinical trials.
4. **Surgical Interventions**: While not experimental, surgery such as vitrectomy or laser therapy might be employed as part of the management strategy for complications like retinal detachment.
Clinical trials often provide access to emerging therapies under compassionate use programs, so consulting with a specialist is critical for the latest developments and appropriate management options. - Lifestyle Recommendations
-
For exudative vitreoretinopathy, lifestyle recommendations primarily focus on managing overall eye health and preventing complications. These may include:
1. **Regular Eye Exams**: Frequent check-ups with an ophthalmologist to monitor the progression and manage any emerging issues promptly.
2. **Protective Eyewear**: Wearing sunglasses to protect eyes from UV light and reducing the risk of further retinal damage.
3. **Avoid Smoking**: Smoking can exacerbate eye diseases and negatively impact overall eye health.
4. **Healthy Diet**: Consuming a diet rich in fruits, vegetables, and nutrients such as omega-3 fatty acids, vitamins A and C, and zinc, which support eye health.
5. **Blood Sugar Management**: For diabetic patients, maintaining blood sugar levels can prevent further complications that affect the eyes.
6. **Physical Activity**: Engaging in regular physical activity to support overall cardiovascular health, which is linked to eye health.
Close monitoring and following the advice of healthcare professionals can effectively manage exudative vitreoretinopathy. - Medication
- There are no specific medications designed to treat exudative vitreoretinopathy directly. Management typically involves addressing complications as they arise, such as retinal detachment. This might include laser photocoagulation, cryotherapy, or vitreoretinal surgery. Regular monitoring by an ophthalmologist is essential.
- Repurposable Drugs
- Exudative vitreoretinopathy is a group of genetic disorders affecting the retina, leading to vision loss. There are currently no specific repurposable drugs widely recognized for this condition. Management typically focuses on monitoring and surgical interventions as needed. Research is ongoing to find effective treatments.
- Metabolites
- Exudative vitreoretinopathy does not have a well-documented list of specific metabolites directly associated with its pathogenesis. Generally, exudative vitreoretinopathy involves abnormal development and function of the retinal vasculature leading to retinal detachment and vision loss. The focus of diagnosis and treatment is usually on imaging techniques and therapeutic interventions rather than metabolic profiling.
- Nutraceuticals
- Exudative vitreoretinopathy is a rare genetic disorder affecting the retina. As of now, there are no specific nutraceutical treatments that have been proven effective for this condition. Nutraceuticals are foods or food products that provide medical or health benefits, but their role in treating genetic retinal disorders remains limited and under-researched. It is essential for patients to consult their healthcare providers for appropriate management and treatment options.
- Peptides
- Exudative vitreoretinopathy is a rare genetic disorder that affects the retina and can lead to vision loss. It is primarily caused by mutations in the NDP, FZD4, LRP5, or TSPAN12 genes. There is currently no widely recognized treatment involving peptides or nanoparticles specifically for exudative vitreoretinopathy. Research in the field of molecular medicine is ongoing, and future treatments may explore these avenues.
