Subconjunctival and episcleral lipid deposits.

Subconjunctival and episcleral lipid deposits.

Biomicroscopical examination of the bulbar conjunctiva and anterior episclera of 1000 randomly selected outpatients showed the presence of multiple discrete lipid globules in 30 per cent. The lipid deposits were asymptomatic. Their prevalence was age-related, while their distribution and composition were consistent with origin from the conjunctival blood vessels.

Delivery from episcleral exoplants.

PURPOSE To assess the impact of an episcleral exoplant on transscleral delivery. METHODS New Zealand White rabbits were given a periocular injection of sodium fluorescein (fluorescein, 376 Da) or an episcleral exoplant loaded with fluorescein. Two types of exoplants were tested: (1) a rigid polyethylene device, impermeable on one side and open to the sclera on the other, that contained compre...

Identification of atherosclerotic lipid deposits by diffusion-weighted imaging.

OBJECTIVES The content and distribution of lipids is an important aspect of plaque vulnerability, but lipids are present within a heterogeneous environment, impeding detection by magnetic resonance imaging. Our goal was to achieve accurate detection of mobile lipids by a single magnetic resonance imaging sequence. METHODS AND RESULTS Carotid endarectomy specimens (n=23) were imaged ex vivo at...
