Severe Subconjunctival Hemorrhage After Intravitreal Injection in a Patient With Hemophilia A

Purpose: To report a patient with severe hemophilia A who received intravitreal antivascular endothelial growth factor (anti-VEGF) for exudative age-related macular degeneration (AMD). Methods: A case and its findings were analyzed. A systematic literature was performed. Results: A patient with severe hemophilia A received intravitreal anti-VEGF for exudative AMD, after which he developed a severe subconjunctival hemorrhage requiring hemostatic intervention. The effects of anti-VEGF in patients with preexisting blood-clotting disorders, such as classic hemophilia, have not been widely reported in the current literature. Conclusions: This case illustrates that precautions must be taken when performing ocular procedures on patients with serious hemostasis disorders.
