PULSED DYE LASER IN THE MANAGEMENT OF SECONDARY TELANGIECTASIA

Abstract

Telangiectasia is a persistent dilated small vessel, 0-1 to 1.0 mm,

'«hich is non pulsatile. Arterial telangiectasia is red and macular while ; venous is blue and often elevated. lt frequently occurs on the face or legs

especially red linear and arborizing telangiectasia. It may occur in normal skin, and they are prominent in areas of chronic actinic damage in fair­ skinned persons long exposed to sunlight, cold or heat. Telangiectasias are thought to occur through the release or activation of vaso-active substances under the effect of many factors as anoxia, chemicals, infections, physical and venous insufficiency . ..- Telangiectasia may be divided etiologically into five groups: Those associated •with genetic inheritance as vascular nevi; as an acquired disease with a secondary cutaneous component as LE; a component of a primary cutaneous disease as rosacea and varicose veins or hormonal excesses and physical damage.
