microaneurysm

 [mi″kro-an´u-rizm]
a minute aneurysm occurring on a vessel of small size, or such as occurs in thrombotic purpura.

mi·cro·an·eu·rysm

(mī'krō-an'yū-rizm),
Focal dilation of retinal capillaries occurring in diabetes mellitus, retinal vein obstruction, and absolute glaucoma, or of arteriolocapillary junctions in many organs in thrombotic thrombocytopenic purpura.

microaneurysm

/mi·cro·an·eu·rysm/ (-an´ūr-izm) a microscopic aneurysm, a characteristic of thrombotic purpura.

microaneurysm

[mi′krō·an′yəriz′əm]
Etymology: Gk, mikros + aneurysma, a widening
a microscopic aneurysm characteristic of thrombotic purpura.

microaneurysm

A minute aneurysmal dilation of arteries, arterioles or capillaries, which is classically seen in the retina of patients with long-standing diabetes and often associated with oedema and haemorrhage. Microaneurysms occur elsewhere in diabetes, as well as in other conditions (e.g., thrombotic thrombocytopenic purpura).

microaneurysm

A teensy-weensy aneurysmal dilation of small arteries, arterioles, or capillaries 'classically' seen in the retina of Pts with long-standing DM, often associated with edema and hemorrhage; MAs occur elsewhere in DM, and in other conditions–eg, thrombotic thrombocytopenic purpura. See Cherry-red spot.

mi·cro·an·eu·rysm

(mī-krō-an'yūr-izm)
Focal dilation of retinal capillaries occurring in diabetes mellitus, retinal vein obstruction, and absolute glaucoma, or of arteriolocapillary junctions in many organs in thrombotic thrombocytopenic purpura.

microaneurysm

focal dilatation of retinal capillaries; characteristic of diabetic retinopathy and glaucoma

microaneurysm

Tiny swelling in the wall of a blood vessel. It appears in the retinal capillaries as a small, round, red spot. It is commonly found in diabetic retinopathy, retinal vein occlusion or absolute glaucoma.

microaneurysm

a minute aneurysm occurring on a vessel of small size, such as one in the retina of the eye or as occurs in thrombotic purpura.
