Coronary thrombolysis with intravenous (IV) streptokinase is widely used as a strategy for coronary reperfusion for acute myocardial infarction (MI). Systemic administration of fibrinolytic agents is associated with hemorrhagic risks such as cerebral hemorrhage, gastrointestinal bleeding, cardiogenic shock, and unusual complications such as splenic rupture, aortic dissection, and cholesterol embolization. Herein, we report a case of intraocular hemorrhage 1 day after the IV administration of streptokinase for acute inferior-wall MI.

| Introduction|| |
Intravenous (IV) streptokinase is one of the oldest fibrinolytic agents used in acute myocardial infarction (MI). Fibrinolytic agents are known to cause bleeding complications such as intracranial hemorrhage, gastrointestinal bleeding, hematuria, and gum bleeding. However, intraocular hemorrhage is not widely seen, especially in patients without any predisposing risk factors such as macular degeneration.
| Case Report|| |
A 65-year-old female presented to our emergency department with complaints of chest pain. Her electrocardiogram showed acute inferior-wall MI [Figure 1]. As she was within the window period, she was thrombolyzed with IV streptokinase 1.5 million units over 60 min. The next morning, she complained of sudden-onset painless vision loss in her right eye. She was nondiabetic but had cataract in both eyes with good visual acuity.

On examination of the right eye, visual acuity was limited to finger counting. No red reflex was observed on fundoscopy, while examination of the left eye revealed normal findings [Figure 2]. There were no features of retinopathy. B-scan of the right eye showed echogenic foci suggestive of vitreous hemorrhage. B-scan of the left eye showed vitreous detachment [Figure 3]. The patient was managed conservatively and was referred to an ophthalmologist for further management.

| Discussion|| |
Coronary thrombolysis with IV streptokinase is widely used as a strategy for coronary reperfusion for acute MI. Intraocular hemorrhage after thrombolytic therapy for acute MI is rare. Kaba et al. described the case of a 66-year-old male with acute inferior-wall MI who developed an extensive retinal and vitreous hemorrhage within a few hours following thrombolytic treatment with reteplase. Grekos and Schocken had also reported a case of bilateral vitreous hemorrhage following IV thrombolysis for acute MI.
Hypertension and exudative macular degeneration have also been reported as potential risk factors, but our patient did not have any of them. Our patient had vitreous detachment in the left eye which usually does not predispose to hemorrhage.
Although our patient had no systemic risk factors for bleeding complications and there was no retinopathy, she still developed a unilateral vitreous hemorrhage following administration of thrombolytic therapy.
Intraocular hemorrhage is a rare adverse effect of streptokinase, but this could be a sight-threatening complication of thrombolytic therapy and needs to be managed properly. The onset of eye pain or vision loss after the administration of a systemic thrombolytic agent should alert the physician to the possibility of an ocular hemorrhage. Early control of intraocular pressure (IOP) may prevent irreversible damage of the optic nerve and significantly improve the prognosis. In cardiac units, prompt medical control of IOP may play a key role in preserving ocular structures.
The potential benefits of systemic thrombolysis in the management of MI often outweigh the risks. While intraocular hemorrhagic complications are rare, any patient with a history of ophthalmic disease, such as age-related macular degeneration, should be advised specifically about the ocular risks of this treatment.
