The ocular surface is at once a complex and beautiful microcosm, and as such we have been fortunate enough to capture what we believe to be stunning images of the structure and functions of this region. Here you will find examples of what the surface of our eyes look like on a microscopic scale.
Primary cell culture of human conjunctival epithelial cells
What we see here is a healthy, confluent colony of primary human conjunctival epithelial cells taken from a donor. A good deal of scientific research relies on the selflessness of tissue donors and we are ever grateful for their contribution to the scientific endeavours of man.
Cornea, conjunctiva, and lid of C57BL/6J mouse.
Shown here is an image of a mouse cornea, conjunctiva, and lid stained with PAS and H&E stains. One can see clearly the stroma and epithelium of the cornea, conjunctival cells, as well as the various structures of the eyelid.
Mouse cornea stained with PAS and H&E stains.
The whole eye of a mouse excised and stained, shown are the retina, cornea, conjunctiva, and eyelid.
Binary Image of Mouse Ocular Surface Damage
Experimental dry eye was induced in a mouse, and the cornea was stained with fluorescein in order to visualize the damage sustained under dry eye conditions. The image was then made binary and assessed using ImageJ software.
Tear Sample from Subject with Moderate Dry Eye
When the tears of a subject with moderate dry eye are collected however, these structures are much larger and more sporadic, you can see the influence of the tear mucosal layer on the structural edges.
Tear Sample from Healthy Subject
When the tears of a healthy subject are collected and dried on a slide, these beautiful "fern-like" structures appear when viewed under a microscope.
