Intracorneal migration of a silicone strap.

Intracorneal migration of a silicone strap.

Horizontal intracorneal swirling water migration indicative of corneal endothelial function.

PURPOSE To test our hypothesis about whether there is water migration in the horizontal corneal plane and investigate its developmental mechanism. METHODS A fluorescein solution was intrastromally injected into normal and edematous corneas of rabbits, and the movement of the fluorescein solution was observed and recorded over time. RESULTS In normal corneas, the water flow was characterized...

Migration of intraocular silicone oil into brain.

Gnanalingham J, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220555 Description An 84 -year-old woman was admitted following a slight mechanical fall while she was in her garden. She had banged the back of her head followed by a brief period of nausea and vomiting which was self-limiting. One year before, the patient underwent surgical repair for retinal detachment of left eye with involvemen...

Transmuscular Migration of a Scleral Tunnel-Secured Encircling Silicone Band

The migration of an encircling silicone band through a rectus muscle is a rare postoperative complication associated with scleral buckling surgery for retinal detachment. In this present study, we describe what we believe to be the first reported case of a patient who experienced postoperative migration of an encircling silicone band through the rectus muscle, despite the band being surgically ...

Migration behaviour of silicone moulds in contact with different foodstuffs.

Various foodstuffs were prepared in silicone baking moulds and analyzed for siloxane migration using a previously developed and validated (1)H-NMR method. Meat loaf significantly exceeded the overall migration limit of 60 mg kg(-1) (10 mg sdm(-1)) in the first and third experiment. The highest siloxane migration found in a meat loaf after preparation in a commercial mould was 177 mg kg(-1). In ...
