2018年6月1日 · Retinal arterial macroaneurysm (RAM) is an acquired focal aneurysmal dilation of an arteri­ole, usually within the first 3 orders of the retinal arterial system (Fig. 1). RAM is uncommon (approximately 1 in 4,500 people) 1 and has a …

2023年9月6日 · An aneurysm is a swelling of a vessel, usually an artery, which carries the risk of bursting and bleeding either on the surface of the eye (rare) or on the retina (very uncommon). They are usually asymptomatic and only are detected on a routine examination which discovers them as an incidental finding, as they cause no symptoms unless located ...

2023年8月25日 · Retinal macroaneurysm is an uncommon entity affecting the posterior segment of the eye, and it has variable presentations. Most macroaneurysms undergo spontaneous resolution. Visual acuity is affected because of edema, …

Macroaneurysms range from 100 to 250μm in diameter and are most often found in the temporal retina, along the supero-temporal arteriole. Associated findings include capillary telangiectasias, vascular remodeling, and retinal edema.

Retinal arterial macroaneurysm (RAM) is described as an acquired, focal dilation of a retinal artery, typically occurring within the first three bifurcations of the central retinal artery. 1–4 RAMs can present with a wide variety of retinal findings and are often misdiagnosed at initial presentation. 3 Formation of a RAM is believed to result ...

An acquired retinal arterial macroaneurysm (RAM) forms when arteriosclerosis leads to weakening of the arteriolar wall and consequently, the arterial wall develops an outpouching that results in a macroaneurysm.

2024年11月17日 · Retinal arterial macroaneurysms (RAMs) are acquired, focal dilations of a retinal artery, most often found in hypertensive patients. While patients with RAMs are often asymptomatic, providers must be able to clinically differentiate them from other retinal conditions so they can manage and counsel patients appropriately.

2010年7月7日 · A retinal artery macroaneurysm (RAMA) is usually described as an idiopathic, acquired dilation of a major retinal arteriole. Typically these develop within its first three bifurcations, at branch points, or areas of arteriovenous crossing.

Retinal arterial macroaneurysm (RAM) is an acquired aneurysmal dilation of the retinal arteriole wall that most commonly arises within the first three orders of arterial bifurcation. The most important risk factors associated with RAM are chronic systemic hypertension (75% of patients), atherosclerotic disease, and serum lipid abnormalities.

Retinal arterial macroaneurysms (RAMs) develop as outpouchings of the arterial wall that is weakened by arteriosclerosis. The traditional treatment of RAMs comprises observation, focal laser photocoagulation, or surgery.
