In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...
A detailed medical illustration of the eye MRI scan of the human eye. Humans have two eyes, ... Sclera; 12. Conjunctiva, 13. Uvea with 14. Iris, 15.
Intraocular pressure may be lowered by allowing drainage of aqueous humor from within the eye to the following routes: (1) filtration through the sclerotomy around the margins of the scleral flap into the filtering bleb that forms underneath the conjunctiva, (2) filtration through outlet channels in the scleral flap to underneath the conjunctiva,(3) Filtration through the connective tissue of ...
An encircling band is a thin silicone band sewn around the circumference of the sclera of the eye. A solid silicone grooved tyre element is also used. Buckles are often placed under a band to create a dimple on the eye wall. [citation needed] The scleral buckle is secured around the eyeball under the conjunctiva. This moves the wall of the eye ...
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
A small flap of the conjunctiva is folded back before making the initial incision perpendicular to the sclera. [ 1 ] The "frown" form is a curve with the ends further from the limbus than the middle, and has a lesser tendency to induce astigmatism or separate on the outside edge.
The blood accumulates between the conjunctiva and the episclera. Diagnosis is generally based on the appearance of the conjunctiva. [2] The condition is relatively common, [4] and both sexes are affected equally. Spontaneous bleeding occurs more commonly over the age of 50 while the traumatic type occurs more often in young males.
Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
