Understanding familial exudative vitreoretinopathy

This story is part of the Current Advances in Regenerative Medicine series. This piece is part of a series dedicated to improving the eyes and restoring vision.

In 1999, I defined regenerative medicine as the collection of interventions that restore tissues and organs damaged by disease, trauma, or the wear and tear of time to normal function. I list a full range of chemical, genetic and protein drugs, cell therapies and biomechanical interventions to achieve this goal.

Familial exudative vitreoretinopathy (FEVR) is a rare genetic disorder that affects the development of retinal blood vessels. This genetic disorder causes abnormal development of blood vessels in the retina, which in turn causes abnormal connections between the arteries and veins in the eye. This can cause blood and other fluids to seep into the retina, causing vision problems such as blurred or distorted vision, partial or complete vision loss, or even blindness.

What is FEVR?

Familial exudative vitreoretinopathy (FEVR) is a genetic disorder affecting the development of retinal blood vessels. Specifically, blood vessels in the retina fail to develop properly, resulting in abnormal connections between arteries and veins. This can cause blood and other fluids to seep into the retina, causing vision problems such as blurred or distorted vision, partial or complete vision loss, or even blindness.

FEVR is a disease that can affect people in different ways. Some people may experience mild vision problems, while others may experience more severe symptoms. Symptoms can also vary between different eyes and even between family members who have the disease. In some cases, the disease may not affect vision. However, people with symptomatic FEVR often experience peripheral vision problems, flashes of light, or floaters at a young age. FEVR may also be associated with other health problems, such as hearing loss or bone abnormalities.

Novel research on FEVR

A research paper published in the journal Molecular Genetics and Metabolic Reports provides valuable insights into the role of the endoplasmic reticulum (ER) membrane protein complex (EMC) in regulating retinal angiogenesis. This study highlights how EMC failure can lead to familial exudative vitreoretinopathy (FEVR).

The results of this study will be critical for the diagnosis, management, and treatment of FEVR and retinal vascular disease. The EMC1 protein is required for retinal blood vessel formation and is critical in the Wnt/-catenin signaling pathway. Identification of EMC1 may lead to new drug targets and treatments. Studies have also used WES analysis to discover genetic variations in the EMC1 gene, which can aid in genetic counseling and selection of patients for gene replacement therapy.

This study reveals the molecular basis of retinal angiogenesis and the relationship between EMC proteins and signaling pathways in retinal development. Finding new candidate genes through WES analysis can help identify the causative genes of other genetic diseases, improve our understanding of disease mechanisms, and enable targeted treatments.

Current treatment strategies

Although there is no cure for FEVR, early diagnosis and treatment can help control symptoms and prevent further vision loss. Familial exudative vitreoretinopathy (FEVR) is treated according to the severity of the eye disease.

If the case is mild, the doctor may not recommend any treatment but simply observe the patient. In moderate to severe cases, the goal is to prevent the progression of neovascularization, which can lead to bleeding and infiltration. Laser photocoagulation or cryotherapy can be used to control neovascularization. At the same time, anti-vascular endothelial growth factor (VEGF) therapy reduces bleeding and exudation.

If fibrovascular proliferation continues, surgery may be needed to address potential complications such as retinal detachment. Surgery may involve removal of the lens or vitrectomy, the removal of the vitreous gel from the eye. Prompt intervention is critical to prevent complications such as vitreous hemorrhage, retinal detachment, and neovascular glaucoma.

Prompt diagnosis and appropriate management of FEVR are critical to preventing complications and preserving vision. Although there is no clear-cut treatment, a personalized approach based on the patient’s specific eye condition and stage can provide the best results.

Familial exudative vitreoretinopathy (FEVR) is a rare genetic disorder that affects the development of retinal blood vessels. This genetic disorder can cause vision problems such as blurred or distorted vision, partial or complete vision loss, and even blindness. Although there is no cure for FEVR, early diagnosis and treatment can help control symptoms and prevent further vision loss.

Current treatment strategies for FEVR include laser photocoagulation or cryotherapy to control neovascularization, and anti-vascular endothelial growth factor (VEGF) therapy to reduce bleeding and extravasation. Surgery may be needed to address potential complications such as retinal detachment, vitreous hemorrhage, and neovascular glaucoma.

Further research into the molecular basis of retinal angiogenesis could help develop targeted therapies and improve patient outcomes. Comprehensive eye examination, genetic testing, counseling and timely intervention can have a significant impact on the management of FEVR.
