Two Cases of Terson’s Syndrome
Abstract
BACKGROUND AND OBJECTIVE: Subarachnoid hemorrhage due to head trauma, rupture of brain aneurysms, etc can be associated with vitreous and retinal hemorrhage and is named Terson’s syndrome and has no adverse effect on visual prognosis and survival if there is no injury to optic nerve and if the brain hemorrhage is initially remove by neurosurgeon. We report two cases of Tersons syndrome with different visual acuity. CASES: Two men of Terson’s syndrome due to car accident that suffered from subarachnoid hemorrhage with decreased vision 2-3 months ago and in fundoscopy examination had retinal hemorrhage especially in the subarachnoid space presented to Farabi eye clinic. Tersons syndrome was characterized by presence of subarachnoid hemorrhage and retinal hemorrhage. They had been operated by neurosurgeon and after improvement of their consciousness, noticed unilateral or bilateral severe visual impairment. The unilateral one best corrected vision (BCVA) was 10/10 in right eye and HM (hand motion) in left eye. The left eye underwent standard 3 port pp.Vit X and the BCVA reached 8/10. The other had bilateral NLP (no light perception) most probably due to optic disc problem.CONCLUSION: Terson’s syndrome should be considered in patients who had previous subarachnoid hemorrhage and are referred to eye clinic because of loss of vision. Eye surgery is utilized if decreased vision is due to vitreous and subhyaloidal hemorrhage and not due to optic nerve injury and with proper operation the prognosis is good.
