27 Possible Causes for Retinal Artery Spasm

  • Acute Hepatic Porphyria

    Summary Epidemiology In the majority of European countries, the prevalence of acute hepatic porphyrias is around 1/75,000. In 80% of cases the patients are female, with the majority aged between 20 to 45 years. Clinical description All acute hepatic porphyrias can be accompanied by neuro-visceral attacks that[…][orpha.net]

  • Acute Intermittent Porphyria

    Acute intermittent porphyria is a rare autosomal dominant disorder caused by a deficiency of the enzyme, hydroxymethylbilane synthase. Recognition of acute neurovisceral attacks can be difficult due to the nonspecific nature of symptoms. We report a case of 33-year-old male patient who presented with recurrent[…][ncbi.nlm.nih.gov]

  • Retinopathy

    BACKGROUND Valsalva retinopathy is a rare but sight-threatening condition with sudden visual loss. Twin-pregnancy is known as a confirmed risk factor for Valsalva retinopathy. CASE REPORT A 21-year-old twin-pregnant Chinese woman with 31 weeks of gestation complained of a sudden decrease of visual acuity in her[…][ncbi.nlm.nih.gov]

  • Preeclampsia

[3] Epidemiology The visual system may be affected in 30–100% of patients with pre-eclampsia.[eyewiki.aao.org] The most common ocular finding is severe arteriolar spasm, evidenced by either segmental or generalized constriction of the retinal arterioles reported in 70% of cases of[eyewiki.aao.org] […] coagulopathy (DIC) can also be found.

  • Retinal Artery Embolism

    Rene et al ( 3 ) reported a case of unilateral blindness following ESS in which direct optic nerve damage occurred in combination with central retinal arterial occlusion ([journals.lww.com] In younger patients, more common causes may include blood clotting disorders, migraine-associated spasm of the retinal artery, and trauma.[retinastl.com] […] to the central retinal artery (e.g. in spine surgeries in the prone position).[en.wikipedia.org]

  • Arterial Embolism

    The blood-flow through any of these vessels may be disrupted during a retinal artery occlusion. Blackage may be caused by emboli, vasculitis, or spasms.[eyewiki.aao.org] Pathophysiology The central retinal artery supplies the inner retina. Occlusion of the retinal arteries results in ischemia of the inner retina.[eyewiki.aao.org] The central retinal artery supplies the inner retina.

  • Retinal Arterial Branch Occlusion

    In younger patients, more common causes may include blood clotting disorders, migraine-associated spasm of the retinal artery, and trauma.[retinastl.com] […] the central retinal artery (e.g. in spine surgeries in the prone position).[en.wikipedia.org] The blood-flow through any of these vessels may be disrupted during a retinal artery occlusion.

  • Quinine Poisoning

    Funduscopy may reveal retinal artery spasm, disc pallor, and macular edema. Although gradual recovery occurs, many patients are left with permanent visual impairment.[mhmedical.com]

  • Central Retinal Artery Occlusion

    […] the central retinal artery (e.g. in spine surgeries in the prone position).[en.wikipedia.org] In only 20-25% cases emboli are visible in the central retinal artery or one of its branches. Inflammation, trauma, and arterial spasm are the other causes.[mjdrdypu.org] The blood-flow through any of these vessels may be disrupted during a retinal artery occlusion.
