Routinely looking for TS findings in CT head scans may prove valuable in clinical practice. Terson's syndrome is associated with female sex and poor clinical condition on admission.
Surgical removal of occipital cavernomas may carry a significant risk of postoperative visual field deficit, and the risk is even higher for deeper lesions. Seizure outcome after removal of these cavernomas appeared to be worse than that after removal in other supratentorial locations. This should be taken into account during preoperative planning.
ABSTRACT.Purpose: To investigate and analyse one hundred-year-old endothelial cells of human transplanted corneal grafts and compare them with intact endothelium of unoperated eyes. Subjects and methods: Specular microscopy was performed on seven individuals (14 eyes) aged >100 years and on seven transplanted corneas with endothelial cells of at least 100 years old. All keratoplasties were performed by the same surgeon (PR) 25-35 years before the time of examination. As controls, 14 unoperated healthy individuals (26 eyes) of 90-100 years, 12 individuals (24 eyes) of 48-52 years, 12 students (24 eyes) of 19-24 years and 11 children (22 eyes) from 10 to 14 years of age were photographed and analysed. Results: The mean cell density in the oldest age group, over 100 years of age (average 102 years), was very good 2365 cells/mm 2 . The mean cell density in the transplanted corneas, the endothelial cells of which were over 100 years old (mean 106 years), was 923 cells/mm 2 (range 585-1800 cells/mm 2 ). Conclusion: Corneal endothelial cells may remain viable and capable to perform their function over 100 years. Donor corneas up to 70-75 years of age can be approved for transplantation, provided that the endothelial cells have been thoroughly evaluated with vital staining before the operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
