Retinal atheromatous plaques: their recognition by elevating the intraocular pressure

Area of Science:

• Ophthalmology
• Vascular Medicine
• Neurology

Background:

• Atheromatous plaques in the central retinal artery are indicators of systemic vascular disease.
• Transient ischemic attacks (TIAs) necessitate thorough examination for underlying causes.
• Current methods for visualizing retinal plaques may not be exhaustive.

Purpose of the Study:

• To evaluate the efficacy of manual globe pressure in enhancing the detection and characterization of retinal atheromatous plaques.
• To determine if this maneuver can reveal previously undetected plaques or provide more detail on existing ones.

Main Methods:

• A simple manual maneuver involving pressure on the globe was applied during ophthalmic examinations.
• The technique was tested on patients presenting with transient ischemic attacks (cerebral or ocular).
• Examinations were conducted irrespective of the presence of carotid artery atheromatous disease.

Main Results:

• Globe pressure enhanced the recognition and study of existing retinal atheromatous plaques in the central retinal artery.
• Previously unseen or suspected plaques were brought into view by this maneuver.
• Visible plaques exhibited increased size and varied color/texture, offering clues to their composition.

Conclusions:

• Manual globe pressure is a valuable, simple adjunct for identifying retinal atheromatous plaques.
• This technique improves diagnostic accuracy for atheromatous disease in patients with TIAs.
• Enhanced plaque visualization aids in assessing the composition and extent of vascular disease.
