Bilateral multiple recurrent branch retinal vein occlusions secondary to hypercoagulopathy associated with multiple mutations: A rare case report

Retinal vein occlusions (RVOs) are relatively common vascular disorders, often resulting in significant visual impairment. We present an intriguing case of a 53-year-old male with recurrent bilateral branch RVOs stemming from underlying hypercoagulopathy. This complex scenario encompassed simultaneous bilateral RVO occurrences and subsequent unilateral recurrences. Despite the absence of systemic comorbidities or conventional risk factors, genetic assessment unveiled notable heterozygous mutations involving Factor V Leiden (G1691A) and Factor II (PT G20210A), along with a homozygous methylenetetrahydrofolate reductase A1298C mutation. While routine hematological indicators remained largely unremarkable, the marked efficacy of anti-vascular endothelial growth factor (anti-VEGF) agents, particularly when administered promptly, emerged as a noteworthy therapeutic avenue. This case underscores the imperative of scrutinizing thrombotic mutations in youthful patients with recurrent RVOs, accentuating the favorable retinal response to anti-VEGF interventions and emphasizing the rewards of timely clinical intervention.
