Bilateral subconjunctival hemorrhage secondary to abciximab use: case report

ABSTRACT CONTEXT: There are no reports on cases of subconjunctival hemorrhage due to use of glycoprotein IIb/IIIa inhibitors. In this report, we present the case of a patient with bilateral subconjunctival hemorrhage after receiving abciximab. CASE REPORT: A 40-year-old male patient underwent coronary angiography after acute anterior myocardial infarction and a coronary stent was placed. Abciximab was added to the therapy because of stent thrombosis. Bilateral subconjunctival hemorrhage was observed after the administration of the abciximab treatment. We treated our patient by stopping abciximab and administering artificial tears. CONCLUSİON: For the first time in the literature, we presented the case of a patient with bilateral subconjunctival hemorrhage after receiving abciximab, which was managed conservatively.

Safety of warfarin therapy during cataract surgery under topical anesthesia / Segurança da terapia com varfarina durante cirurgia de catarata com anestesia tópica

ABSTRACT Purpose: To analyze the safety of warfarin therapy during cataract surgery under topical anesthesia. Methods: This was a prospective nonrandomized comparative study of 60 eyes of 60 patients treated with or without concurrent oral warfarin anticoagulant therapy, referred for cataract surgery under topical anesthesia. The sample included a treatment (n=30) and a control (n=30) group. Results: There were no records of intraoperative or postoperative intracameral bleeding complications in both the groups. At 1-month postoperative follow-up, 90.0% of patients presented spectacle-corrected visual acuity of at least 20/40. Conclusion: Cataract surgery by phacoemulsification with topical anesthesia can be successfully conducted without discontinuing warfarin. .

RESUMO Objetivo: Avaliar a segurança da cirurgia de catarata com anestesia tópica em pacientes em uso de varfarina. Métodos: Estudo comparativo não aleatorizado, prospectivo de 30 olhos de 30 indivíduos sob terapia anticoagulante por via oral com Varfarina que se submeteram à cirurgia de catarata com anestesia tópica. O grupo controle foi composto por 30 olhos de 30 pacientes, com indicação de cirurgia de catarata, que não faziam uso de terapia anticoagulante. Resultados: Não houve registro de complicações hemorrágicas intracamerais transoperatórias ou pós-operatórias em ambos os grupos. Na visita pós-operatória de 30 dias, 90,0% dos pacientes apresentavam acuidade visual corrigida por óculos de pelo menos 20/40. Conclusão: A cirurgia de catarata por facoemulsificação com anestesia tópica pode ser realizada com sucesso sem interrupção da terapia com varfarina. .

An unusual complication of anticoagulant therapy: bloody tears

A seventy two year old white male developed bleeding from a right eye subcondunctival hemorrhage. The patient had been taking warfarin and, it was immediately discontinued. Two doses of 15 mgs. each of Vitamin K given parentally reduced the prothrombin time, but not the oozing of blood which finally stopped after the administration of fresh frozen plasma. Fortunately, no retrobulbar or intra-ocular bleeding ocurred. This complication during the use of anticoagulants has never, to our knowledge, been reported before in the medical literature
