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[merckmanuals.com] Diabetic retinopathy - Three main categories exist: background, or "simple," retinopathy, consisting of microaneurysms, hemorrhages, exudates, and retinal edema; preproliferative[health.am] , vitreous hemorrhage, and traction retinal detachment.[merckmanuals.com]

  • Retinopathy

    The first signs of nonproliferative retinopathy are Capillary microaneurysms Dot and blot retinal hemorrhages Hard exudates Cotton-wool spots (soft exudates) Hard exudates[merckmanuals.com] 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.[improveyourvision.com] […] and traction retinal detachment.[merckmanuals.com]

  • Hypertensive Retinopathy

  • Radiation Retinopathy

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

  • Streptococcus Pyogenes

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

  • Diabetes Mellitus

    It is characterized initially by retinal capillary microaneurysms and later by macular edema and neovascularization.[web.archive.org] 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[doi.org] Diabetic retinopathy: Diabetic retinopathy is the most common cause of adult blindness in the US (see also Retinal Disorders: Diabetic Retinopathy ).[web.archive.org]

  • 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[emedicine.medscape.com] ; ; caliber changes in venous vessels; intraretinal hemorrhage ; hard exudates ; retinal edema, and cotton-wool spots Visual loss, most commonly due to macular edema Proliferative[amboss.com] As the microaneurysms or retinal capillaries become more permeable, hard exudates appear, reflecting the leakage of plasma.[emedicine.medscape.com]

  • Arteriosclerosis

    […] venules, sausage-like bulging of central main arterioles and microaneurysms of arterioles of the central fundus.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov]

  • 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[medical-dictionary.thefreedictionary.com] Classification Proposed disease severity level Findings on Ophthalmoscopy No apparent retinopathy No abnormalities Very Mild NPDR Few Microaneurysms only Mild NPDR Few microaneurysms[slideshare.net] Intramural pericyte loss Loss of autoregulation of retinal capillaries à weakening of the capillary wall à microaneurysm formation If microaneurysms rupture, they form small[hkuelcn.med.hku.hk]

  • Hypotension

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