71 Possible Causes for Retinal Blood Vessels Attenuated

  • Hypertensive Crisis

    If the retinal vasculature retains autoregulation ability, vessels will maintain a small caliber to cope with high blood pressure.[] In early stages of hypertensive retinopathy, arteriolar attenuation first becomes apparent. This is a normal autoregulation response to elevated blood pressure.[] : Clinical picture of hypertensive retinopathy Two pathological changes progress as hypertensive retinopathy worsens: a loss of autoregulation ability and a breakdown of Blood-Retinal-Barrier[]

  • Preeclampsia

    vessel analysis and blood pressure measurements throughout gestation, he found that those who later developed preeclampsia had significant attenuation early in gestation.[] […] epithelium damage and Purtscher like retinopathy have been reported. [2] [3] [4] Risk Factors In a report published by Lupton et al, following normotensive pregnant women with retinal[]

  • Occlusion of the Ophthalmic Artery

  • Retinitis Pigmentosa

    (narrowing) of the retinal blood vessels.[] , and (3) the attenuation of blood vessels in the retina. [3] Non-syndromic RP usually presents a variety of the following symptoms: [ citation needed ] Night blindness Tunnel[] […] bone spicules, because of their similarity to the microscopic appearance of bone), pallor (paleness) of the optic disc (or optic nerve head, part of the optic nerve) and attenuation[]

  • Retinal Perforation

    […] the retinal vessels (sometimes referred to as “boxcarring”) and attenuation of retinal arteries; cherry-red spot at the fovea; pale fundus; pupil may be dilated and react[] Funduscopic examination after CRAO reveals interrupted columns of blood within the retinal vessels (sometimes referred to as “boxcarring”) and retinal pallor secondary to[] […] retinal edema, with a characteristic cherry-red spot at the fovea and attenuation of the retinal arteries.[]

  • Autosomal Dominant Rhegmatogenous Retinal Detachment

    Those changes are accompanied by disc atrophy and attenuation of the retinal arterioles. Finally, the visual field constricts totally and vision is lost.[] Later the fundus exam shows black "bony spicules" of pigment scattered throughout the mid-periphery of the retina, bordering the blood vessels and progressing toward the posterior[]

  • Retinitis Pigmentosa with Situs Inversus

    retinal blood vessels; HP:0007737; bone spicule pigmentation of the retina; HP:0001133, constriction of peripheral visual field; HP:0000662, nyctalopia ABCA4 ABCA4 1 3 Hao[] , with/without situs inversus HP:0007663, reduced visual acuity; HP:0000505, visual impairment; HP:0007722, retinal pigment epithelial atrophy; HP:0007843, attenuation of[] 00145073 7297-02348 - 4-generation family, 3 affected (2 males, 1 female), unaffected consanguineous deceased parents F yes China Asian-Chinese 41y 0 yes none retinitis pigmentosa[]

  • Retinal Artery Embolism

    […] supplied by the occluded branch retinal arteriole; there is frequently attenuation and boxcarring of the blood column in the vessels in the involved region, with or without[] Attenuation and “boxcarring” of the blood column in the involved region were observed in OU.[] After the second bifurcation of the superior temporal retinal vessel, a small embolus (or fragment of the first one) is observed (a′).[]

  • Optic Papillitis

    . • Reduction in number of small blood vessels on the disc surface (Kestenbaum sign). • Attenuation of parapapillary blood vessels and thinning of the retinal nerve fibre[]

  • Neuronal Ceroid Lipofuscinosis

    Retinal blood vessels may be attenuated and lens opacities of various types are common.[]
