A pediatric cardiologist performed transthoracic echocardiography and reported some bright spots on the right coronary artery with the suggestion of thrombi or microaneurysms
HIV retinopathy is an occlusive microangiopathy,  which presents as cotton wool spots, telangiectasia, microaneurysms
and retinal haemorrhages.
7] Various fundus changes include microaneurysms
, hemorrhages, cotton wool spots, intraretinal microvascular abnormalities, and venous abnormalities.
Retinal pathology is an important consequence of OIS in humans presenting with venous dilation, retinal hemorrhage, and microaneurysms
, narrowing of the retinal arterioles, and venous dilation are observed on fundus examination due to decreased flow in the ophthalmic artery.
A technique for the programmed detection of microaneurysms
(MAs) in color retinal pictures is proposed.
Cotton wool spots and microaneurysms
may also be seen.
Focal edema is well-circumscribed macular thickening associated with complete or incomplete rings of hard exudates caused by leakage from one or more individual microaneurysms
Diabetic retinopathy begins with microaneurysms
and progress into exudative changes, blood (blot hemorrahges), ischemic changes, collateralization, dilatation of venules and proliferative changes3.
within the macular areas were treated by focal application of laser shots sufficient to bleach them.
Focal macular edema is characterized by fluorescein leakage from certain capillary areas, and it may be surrounded by hard exudates (circinate exudates) that are yellow to white in color and contain lipoprotein remnants of plasma extravasation from microaneurysms
Nonproliferative retinopathy occurs when small blood vessels become partly occluded, leading to microaneurysms
and leaking of capillary fluid.
