129 Possible Causes for Retinal Microaneurysm

  • Proliferative Retinopathy

    Klein R, Meuer SM, Moss SE, Klein BE (1989) The relationship of retinal microaneurysm counts to the 4 year progression of diabetic retinopathy.[link.springer.com] In the nonproliferative form, damage to small retinal blood vessels leads to microaneurysms, retinal hemorrhages, exudates, cotton wool spots, and retinal swelling (known[vrssurgery.com] 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]

  • Diabetic Retinopathy

    This classification is characterized by the presence of at least one retinal microaneurysm or hemorrhage.[reviewofoptometry.com] 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] As a result microaneurysms and macular edema occurs.[symptoma.com]

  • Retinopathy

    The earliest ophthalmologically visible signs are microaneurysms and retinal hemorrhages.[institut-vision.org] 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] […] and traction retinal detachment.[msdmanuals.com]

  • Hypokalemic Nephropathy

    Examination shows scattered retinal microaneurysms bilaterally. The remainder of the examination shows no other abnormalities.[usmleforum.com]

  • Cutis Marmorata Telangiectatica Congenita

    Fluorescein angiogram of the right eye shows peripheral retinal microaneurysms and abnormal telangiectatic and anastamotic vessels. Figure 2.[healio.com] Dilated fundus exam revealed abnormal peripheral retinal vasculature in both eyes.[healio.com] Fluorescein angiography was performed using a RetCam system (Clarity Medical Systems, Pleasanton, CA) and demonstrated microaneurysms, telangiectatic vessels, and an abnormal[healio.com]

Macular edema What are 6 complications of radiation retinopathy?[neuro-ophthalmology.stanford.edu] Key findings include the following: Retinal hemorrhages Retinal microaneurysms Retinal exudates Cotton wool spots Macular edema Complications of radiation retinopathy include[neuro-ophthalmology.stanford.edu] […] be asymmetric) Narrowing and irregularity of retinal arteries Arteriovenous nicking (narrowing of retinal veins at arteriovenous crossing sites) Retinal hemorrhages Microaneurysms[neuro-ophthalmology.stanford.edu]

  • Acute Myelocytic Leukemia

    Capillary closure, retinal microaneurysms and neovascularization following massive fundus hemorrhage could be involved in few of the above instances.[ncbi.nlm.nih.gov] Characteristic signs of leukemic retinopathy include bilateral intra-retinal hemorrhage, white-centred hemorrhage, macular hemorrhage and cotton-wool spots.[ncbi.nlm.nih.gov]

  • Cerebral Embolism

    In addition to the formation of aneurysms in cerebral arteries, we report here the unique picture of a retinal involvement consisting in microaneurysm formation associated[ncbi.nlm.nih.gov]
