A 20-year-old male patient reported to ophthalmology outpatient department with complaint of loss of vision in right eye since childhood and diminished vision in left eye for 1month of duration. Funduscopy revealed right side optic atrophy and left sided vitreous hemorrhage. Non-contrast computed tomography study of head showed hyperdense circle of Willis and cerebral venous sinuses. No contrast was given before the computed tomography scan of head. Bilateral orbit showed right sided oval enlarged eye ball with medial deviation and normal left eye ball. Magnetic resonance venography was advised to rule out sinus venous thrombosis which revealed normal study of sinuses. On clinical examination, the patient had clubbing of all fingers, mild cyanosis, hyperemia of lower conjunctiva and systolic murmurs on auscultation with raised hematocrit level (72 percentage). Echocardiography examinations of the patient shows features of tetralogy of Fallot (TOF). The hyper-dense vessel was due to raised hematocrit (secondary polycythemia Vera).
