Familial Exudative Retinopathy: A Case and Family Analysis

Area of Science:

• Ophthalmology
• Genetics
• Retinal Diseases

Background:

• Familial exudative vitreoretinopathy (FEVR) is a rare inherited disorder affecting retinal angiogenesis.
• It can lead to significant vision impairment if not diagnosed and managed promptly.
• Clinical diagnosis relies on characteristic fundus findings and family history.

Purpose of the Study:

• To diagnose and stage Familial Exudative Vitreoretinopathy (FEVR) in a patient and his family members.
• To highlight the importance of family screening in identifying FEVR.
• To describe the clinical presentation and diagnostic findings of FEVR.

Main Methods:

• Clinical evaluation of a 49-year-old male patient with suspected retinal vascular issues.
• Ophthalmic examinations including visual acuity, fundus photography, optical coherence tomography (OCT), and fundus fluorescein angiography (FFA).
• Examination of the patient's brother to assess for familial inheritance.

Main Results:

• The patient presented with features of FEVR including retinal vascular abnormalities, macular dragging, and neovascularization.
• Fundus fluorescein angiography revealed avascular retinal areas and leakage.
• The patient was diagnosed with Stage 2A FEVR, and his brother with Stage 1 FEVR, confirming familial inheritance.

Conclusions:

• FEVR is a clinically diagnosed inherited retinal disorder.
• Family examinations are essential for early detection and management of FEVR.
• Prompt diagnosis and follow-up can help prevent vision loss in affected individuals.
