Retinal Complications of Gas Myelography

Visual Impairment Following Epidural Fluid Injections and Epiduroscopy: A Review

“…Intraocular pressures were measured after the ocular event in the cases. On follow‐up examinations, only 20.8% of cases had residual vision loss or residual hemorrhages [2–9].…”

“…The average amount of CSF in a human is about 130 mL [2]. As CSF flows through a closed, poorly expansible system, any addition of fluid to this system without corresponding removal in a timely fashion will result in an increased pressure.…”

“…Also, a hypersecretion of CSF by the choroid plexus occurs if the dura is punctured and CSF is lost [37]. In combination, these two mechanisms may overcorrect and ultimately result in increased CSF pressure [2].…”

Vitrectomy in two cases of bilateral Terson syndrome

“…Arterial blood supply through the central retinal artery is increased, due to purely mechanical conditions as well as reactive stimulation by the vasomotor center caused by cerebral ischaemia (Oberman et al, 1979).…”

“…SAH is not always the cause of intracranial hypertension; similar clinical pictures have been reported after strangulation, trauma and air myelography (Anderson and Ford, 1980;Duke-Elder, 1974;Khan and Frenkel, 1975;Oberman et al, 1979;Rebeller and Desplat, 1980). Trauma may also lead to Purtscher's retinopathy, especially after compression of the thorax.…”
