Abstract: Terson syndrome is an intraocular hemorrhage caused by intracranial hemorrhage, which is particularly common in patients with subarachnoid hemorrhage. At present, the specific pathogenesis of Terson syndrome is not clear, but the current mainstream pathogenesis is as follows: first, intracranial hemorrhage leads to increased intracranial pressure, and increased intracranial pressure leads to blocked retinal venous reflux, resulting in venous obstructive bleeding; the other is intracranial hemorrhage along the optic nerve sheath into the eye, causing intraocular hemorrhage. Recently, the lymphatic system from the intracranial to the eyeball has become a new research direction of this disease, providing another possibility for the pathogenesis of Terson syndrome and possibly a new way of thinking for other ophthalmic diseases.
