134 Possible Causes for Arteriolar Attenuation

  • Neuronal Ceroid Lipofuscinosis Type 3

    The fundus shows a bull's eye maculopathy, diffuse pigmentary degeneration, arteriolar attenuation and optic atrophy, and an extinguished ERG.[] attenuation, and optic atrophy.[] Ocular features include Rotary nystagmus Eccentric viewing/overlooking Normal to severe pigmentary retinopathy with optic disc pallor, arteriolar attenuation, peripheral pigmentation[]

  • Retinal Artery Embolism

    Right eye fundus showed haemorrhages, hard exudates, arteriolar attenuation and arteriovenous crossing changes suggestive of hypertensive retinopathy (Figure 1A).[] Arteriolar attenuation was noted at all retinal quadrants and the macula was severely oedematous ( Figure 3 ).[] attenuation.[]

  • Retinal Arterial Branch Occlusion

    The retina initially appeared ischemic with severe arteriolar attenuation, a cherry red spot, and a pale optic disc.[] attenuation.[] attenuation, and a sclerosed vessel, box-carring and refractile plaques emanating from the superior portion of the optic nerve head ( figure 1 ).[]

  • Hypertensive Crisis

    In early stages of hypertensive retinopathy, arteriolar attenuation first becomes apparent. This is a normal autoregulation response to elevated blood pressure.[] For example, the Atherosclerosis Risk in Community (ARIC) Study found a positive correlation between arteriolar attenuation and concurrent left ventricular hypertrophy in[]

  • Retinitis Pigmentosa

    Both eyes had optic disc pallor, arteriolar attenuation, and peripheral bony spicules suggestive of the triad of retinitis pigmentosa.[] Pathology RP is characterised by changes in pigment and arteriolar attenuation, often with some degree of optic nerve atrophy.[]

  • Preeclampsia

    […] early in gestation. [5] Li found that in pregnant women every 10-mmHg increase in mean arterial blood pressure was associated with a 1.9-μm reduction in retinal arteriolar[] […] normotensive pregnant women with retinal vessel analysis and blood pressure measurements throughout gestation, he found that those who later developed preeclampsia had significant attenuation[]

  • Benign Concentric Annular Macular Dystrophy

    attenuation and further decline of the ERG, as found in retinitis pigmentosa ( 2, 3 ).[] […] follow-up study of an affected Dutch family showed that there was a pronounced involvement of the peripheral retina, increased photoreceptor dysfunction, waxy optic disc, arteriolar[]

  • Familial Benign Flecked Retina

    . • Scattered whitish-yellow spots • most numerous at the equator • Usually sparing the macula • associated with arteriolar attenuation • similar to the spots in fundus albipunctatus[] Bone specule pigmentation Arteriolar attenuation Waxy disc pallor C/Fx: Low V.A.[] attenuation Flecks extending to the disc PROGRESSION Progressive visual acuity and visual field loss Stationary Visual field loss Visual loss due to RPE degeneration FFA[]

  • Arteriosclerotic Retinopathy

    It consists of mild generalized arteriolar attenuation, particularly of small branches, with broadening of the arteriolar light reflex and vein concealment.[] Retinal arteriolar narrowing or attenuation is a defining sign of hypertensive retinopathy and is considered to be an autoregulatory physiological response to initial vasospasm[] It comprises marked generalized narrowing and focal attenuation of arterioles associated with deflection of veins at arteriovenous crossings (Salus’ sign).[]

  • Retinitis pigmentosa 40

    Pathology RP is characterised by changes in pigment and arteriolar attenuation, often with some degree of optic nerve atrophy.[] Slight retinal arteriolar attenuation Electroretinogram (ERG) showed diminished b-wave amplitudes in both photopic and scotopic phases with a marked reduction in the amplitude[] In more advanced stages patients show retinal arteriolar attenuation, bone spicule pigmentation around the periphery in most cases, and waxy pallor of the optic discs.[]
