Cortical blindness, a rare complication of pre-eclampsia

Cerebral Vasospasm in Cortical Blindness Associated with Preeclamsia/ Eclampsia Syndrome

“…Cortical blindness is usually reversible. However, visual loss by infarcts may be permanent [66][67][68][69][70][71][72][73][74][75]. We do not have an explanation for the cortical blindness remission before resolution of vasospasm in patient 1 and 2.…”

“…Other authors have reported CVS with cortical blindness: PRES-cortical blindness associated with eclampsia [63][64][65][66][67][68]. PREScortical blindness associated with preeclampsia without seizures [54][55][56][57].…”

“…RCVS-cortical blindness associated with preeclampsia [36,59] and the coexistence of PRES/RCVS-cortical blindness associated with eclampsia [37]. Cortical blindness can be the primary clinical manifestation and be preceded seizures [9,[65][66][67]. The mechanism is unclear whether it results from vasogenic edema or vasospasm and ischemic injury, TCD had demonstrated findings of vasospasm in temporary blindness associated with preeclampsia.…”

Clinical assessment of retinopathy post management of pregnancy induced hypertension

“…[3] Visual symptoms may be the precursor of seizures. [4] Various changes in the fundus and visual problems reported in patients of PIH include spasm and focal/generalized narrowing of retinal arterioles, [5] hemorrhages, [5] exudates, [5] peripapillary or focal retinal edema, [5] serous retinal detachment, [6] isolated cases of acute ischemic optic neuropathy, [7] transient blindness, [8] cortical blindness, [9][10][11] exudative retinal detachment, retinal pigment epithelial lesions, [12] permanent blindness secondary to central retinal artery occlusion [13,14] and optic atrophy. [15,16] Optic atrophy secondary to retinal vascular involvement is unusual but may cause visual impairment.…”

Acute cortical blindness caused by pre-eclampsia in the antepartum; posterior reversible encephalopathy syndrome (PRES)

“…Visual abnormalities in PRES commonly include blurred vision, hemianopia, visual neglect, etc 1 . Reversible cortical blindness is a very rare symptom 5 .…”
