110 Possible Causes for Retinal Microaneurysm

  • Diabetic Retinopathy

    The first signs of nonproliferative retinopathy are Capillary microaneurysms Dot and blot retinal hemorrhages Hard exudates Cotton-wool spots (soft exudates) Hard exudates[] Diabetic retinopathy - Three main categories exist: background, or "simple," retinopathy, consisting of microaneurysms, hemorrhages, exudates, and retinal edema; preproliferative[] , vitreous hemorrhage, and traction retinal detachment.[]

  • Retinopathy

    The first signs of nonproliferative retinopathy are Capillary microaneurysms Dot and blot retinal hemorrhages Hard exudates Cotton-wool spots (soft exudates) Hard exudates[] Microaneurysms and other areas of abnormal retinal blood vessels may leak fluid, causing the retina to swell or bleed. This may lead to vision loss.[] […] and traction retinal detachment.[]

  • Hypertensive Retinopathy

    retinal microaneurysm retinal vein occlusion Symptoms of hypertensive retinopathy: Headaches Visual disturbances, and sometimes sudden vision loss Tests & Diagnosis of hypertensive[] Once the retinal blood vessels undergo arteriosclerosis, further risks for developing retinal artery and vein occlusions and retinal microaneurysms become inevitable which[] In a nested case–control analysis of the Beaver Dam Eye Study, individuals with retinal microaneurysms and retinal haemorrhages were twice as likely to die from cardiovascular[]

  • Radiation Retinopathy

    Fluorescein angiography showed edema associated with microaneurysms, retinal telangiectasia, and capillary nonperfusion.[] The most commonly encountered ophthalmoscopic signs of retinopathy include retinal hard exudates, hemorrhages, microaneurysms, cotton-wool spots, and telangiectases.[] Ophthalmic examination may reveal signs of retinal vascular disease, including cotton-wool spots, retinal bleeds, microaneurysms, perivascular sheathing, capillary telangiectasis[]

  • Streptococcus Pyogenes

    CONCLUSIONS: The retinal granulomatous lesion was caused by streptococcal infection in pyoderma and later became more vasoproliferative with macroaneurysms and microaneurysms[] The leakage was remedied by laser photocoagulation to the retinal lesion.[]

  • Diabetes Mellitus

    It is characterized initially by retinal capillary microaneurysms and later by macular edema and neovascularization.[] If a person has had diabetes for 20–25 years following puberty without signs of retinal, nerve, or kidney disease or if complications are minimal (e.g., one or two microaneurysms[] Diabetic retinopathy: Diabetic retinopathy is the most common cause of adult blindness in the US (see also Retinal Disorders: Diabetic Retinopathy ).[]

  • Diabetes Mellitus Type 2

    The following are the 5 stages in the progression of diabetic retinopathy: Dilation of the retinal venules and formation of retinal capillary microaneurysms Increased vascular[] ; ; caliber changes in venous vessels; intraretinal hemorrhage ; hard exudates ; retinal edema, and cotton-wool spots Visual loss, most commonly due to macular edema Proliferative[] As the microaneurysms or retinal capillaries become more permeable, hard exudates appear, reflecting the leakage of plasma.[]

  • Arteriosclerosis

    […] venules, sausage-like bulging of central main arterioles and microaneurysms of arterioles of the central fundus.[] The ophthalmological findings in 5 boys and 1 girl between 7 and 17 years of age were retinal vascular tortuosity of main vessels, pre-capillary arterioles and post-capillary[]

  • Peripheral Vasoproliferative Retinopathy

    The nonproliferative form is characterized by dilation of the retinal veins and microaneurysms which may leak blood cells and/or plasma, causing internal hemorrhaging or edema[] Classification Proposed disease severity level Findings on Ophthalmoscopy No apparent retinopathy No abnormalities Very Mild NPDR Few Microaneurysms only Mild NPDR Few microaneurysms[] Intramural pericyte loss Loss of autoregulation of retinal capillaries à weakening of the capillary wall à microaneurysm formation If microaneurysms rupture, they form small[]

  • Hypotension

    Fundus examination disclosed prominent retinal arteries as well diffuse microaneurysms, widespread intraretinal hemorrhages, and hyperemic optic disks.[]
