In vivo confocal microscopy of the palpebral conjunctiva and tarsal plate
The aim of this work is to develop a more complete understanding of the in vivo histology of the human
palpebral conjunctiva and tarsal plate.
Methods. The upper eyelids of 11 healthy human volunteer subjects were everted, and laser scanning confocal
microscopy was used to examine the various tissue layers of the palpebral conjunctiva and tarsal plate.
The superficial and basal epithelial layers are composed of cells with gray cytoplasm and thick, light gray borders.Nuclei can not be seen. The stroma has a varied appearance; fibrous tissue is sometimes observed, interspersed with dark,amorphous lacunae, and crevases. Numerous single white or gray cells populate this tissue, and fine blood vessels are seen traversing the field. Occasional conjunctival microcysts and Langerhans cells are observed. The tarsal plate is dark and amorphous, and meibomian gland acini with convoluted borders are clearly observed. Acini are composed of an outer lining of large cuboidal cells, and differentiated secretory cells can be seen within the acini lumen.
Laser scanning confocal microscopy is capable of studying the human palpebral conjunctiva, tarsal plate,
and acini of meibomian glands in vivo. The observations presented here may provide useful supplementary anatomical
information relating to the morphology of this tissue.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
