Familial Exudative Vitreoretinopathy.

Area of Science:

• Ophthalmology
• Genetics
• Pediatrics

Background:

• Familial exudative vitreoretinopathy (FEVR) is a hereditary retinal disorder primarily affecting children, leading to significant visual impairment.
• Genetic mutations in NDP, FZD4, LRP5, and TSPAN12 are implicated in FEVR, exhibiting diverse inheritance patterns (X-linked recessive, autosomal dominant, autosomal recessive) and variable clinical presentations.
• The disease is characterized by peripheral retinal avascularity, progressing to neovascularization, exudation, and retinal detachment, often influenced by specific mutations.

Approach:

• Review of genetic factors and clinical manifestations of FEVR.
• Discussion of diagnostic methods, including wide-field imaging with fluorescein angiography.
• Outline of management strategies for FEVR, emphasizing early intervention.

Key Points:

• FEVR presents with peripheral retinal avascularity, neovascularization, exudation, and potential retinal detachment.
• Genetic heterogeneity and variable expressivity are hallmarks of FEVR.
• Early diagnosis and prompt treatment (laser photocoagulation, anti-VEGF, surgery) are critical for preserving vision.
• Identifying affected family members, even asymptomatic ones, is crucial for comprehensive management.

Conclusions:

• FEVR is a complex inherited retinal disease requiring a multidisciplinary approach for optimal outcomes.
• Timely diagnosis and tailored treatment strategies, guided by genetic and phenotypic information, are essential to prevent irreversible vision loss.
• Wide-field imaging and careful differential diagnosis are vital components in managing pediatric vitreoretinopathies like FEVR.
