Abstract:
Tranexamic acid (TXA) is an antifibrinolytic commonly used to reduce blood loss due to surgical procedures, heavy menstruation, trauma, bleeding disorders, among other uses. Possible adverse reactions associated with TXA include abdominal pain, headache, fatigue, cerebral thrombosis, dizziness, retinal artery occlusion, chromatopsia, and more. We present a case of acute color vision disturbance developed soon after initiation of oral TXA for epistaxis prophylaxis in the setting of factor VII deficiency. To our knowledge we report the only case of color vision disturbance in a pediatric patient and the only case after receiving oral TXA. Soon after discontinuing oral TXA the patient's altered perception of color vision resolved. The patient was subsequently discharged home with a prescription for an alternative antifibrinolytic (aminocaproic acid) and follow-up with neuro-ophthalmology.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
