Walsh & Hoyt: Spontaneous or Traumatic Hemorrhage

Patients in whom visual loss occurs after spontaneous hemorrhage are usually 4060 years old and debilitated. Most of these patients have experienced repeated episodes of bleeding, but cases following a single episode of massive hemorrhage with secondary hypotension have been reported. The visual loss is usually bilateral, but it may affect both eyes asymmetrically or be unilateral. The severity of visual loss ranges from mild or transient blurred vision in one eye to irreversible total blindness in both eyes. Both AION and PION have beenreported inthis setting, although AION is more common.
