Conjunctiva - Essay Example

Comments (0) Cite this document
Summary
The conjunctiva is the membrane over the eyeball that lines the sclera (white part of the eye) and the inside of the eyelids. The membrane produces mucus, as well as tears, to deal with the myriad of objects and germs that penetrate the eye on a daily basis; this is a delicate tissue and yet it is fit to withstand particles of dust and dirt as well as certain bacteria without succumbing to infection or permanent damage…

Download file to see previous pages The illness most frequently attributed to this part of the body is conjunctivitis, more commonly known as pink-eye, and this infection has helped researchers to understand how wearing contact lenses can affect the conjunctival capillaries: the tiny blood vessels that are responsible for the interchange of oxygen and other substances between the blood and the conjunctiva tissue.
Contact Lens Papillary Conjunctivitis, or CLPC, is the most common reasons for contact lens wearers to discontinue their usage of lenses. This infection has been directly attributed to the use of contact lenses and in studies using control groups of non-lens wearers it became clear that wearing contact lenses changes the condition of the conjunctival capillaries and therefore the overall condition of the conjunctiva. Studies conducted by Australian researchers showed that while wearing a contact lens, users are reducing the tear and mucus flow under the contact itself, therefore inhibiting the cleansing fluids produced by the conjunctiva from essentially washing away dirt and bacteria. Where the conjunctival capillaries were concerned, the researchers noted a decrease in perfusion, meaning that the capillaries were under pressure and therefore unable to function properly. The compression of the conjunctival capillaries is something that researchers wanted to understand better, in relation to how exactly it affected each lens wearer as opposed to non-contact lens wearers (Augusto et al, 2002).
The conjunctiva relies on working capillaries just as any other tissue within the body so that oxygen can reach it and provide proper nutrition. This is the essential circulation of materials from the bloodstream to the tissue that occurs all throughout the body, and needless to say the medical and scientific community is interested in understand just how this basic circulation is affected by the presence of a contact lens. Because lenses slow the conjunctival circulation process, eye-care specialists have been vigilant in monitoring their patients to see whether this will have any adverse effects. Certainly most contact lens wearers have reported dry eyes and this has been countered with the use of special eye-drops designed to keep the eye moist in place of properly working conjunctival capillaries.
Normally, conjunctival blood cells will mimic that of the rest of the body, however given extensive contact lens use and the susceptibility to conjunctivitis, the presence of white blood cells within the area is often higher than in a non-contact lens wearer. Basically, people who wear contact lenses have to deal with the fact that their conjunctiva is compressed and that the conjunctival capillaries are in turn compressed and unable to supply blood to the membrane in a normal manner. This in turn promotes the build up of bacteria and dry eyes, which will subsequently call for the production of more white blood cells through the capillaries which are used for healing infections and ridding the membrane of harmful bacteria.
Researchers studying CLPC noticed that lens wearers with the infection, opposed to wearers without the infection, showed no significant differences in the build-up of conjunctival capi ...Download file to see next pagesRead More

Conjunctiva and Contact Lenses

..., and through these studies scientists are able to look directly at cells of any tissue and ascertain their state of health (Anshu et al, 2001). Impression cytology has allowed researchers to look more closely at the cells within the conjunctiva and to study the differences between those tissues that were not exposed to contact lenses and those that were. Various studies have been carried out on various specifications, however it is the cell density that interests many scientists and medical professionals. Cell density, and in particular the density of what are called Goblet cells, are of importance to contact lens studies in relation to the conjunctiva. Cytology of the conjunctiva is best served by the in vivo method which deals...

A number of previous studies have reported a compromise of the conjunctiva during contact lens wear, presumably as a result of the direct mechanical effects of lens wear; these include conjunctival staining, hyperaemia, chemosis and folding, and an apparent depletion of the number of conjunctival goblet cells (inferred from impression cytology studies). In a study conducted by Aragona P, Ferreri G, Micali A, Puzzolo D. in 1998 to detect the morphological changes of the conjunctival epithelium in contact lens wearers evaluated...

Use of the slit-lamp for anterior segment examination of the eye

...diminished vision. I drew down his lower lid while he was asked to look towards the ceiling, and the lower fornix looked normal. This excluded any inflammation of the lower lid and swelling that can compromise vision temporarily. The upper lid was everted to examine the upper palpebral conjunctiva. These examinations ruled out conjunctival hemorrhage and any other adnexal disease that might have caused his visual impairment. Since there were no exudates and congestion, it could be safely assumed that there was no inflammation of the conjunctivae. Although there were no misplaced lashes, sometimes a lash irritates the eye to lead to blepharospasm, swelling, irritation, and even inflammation of the cornea...

In this manner, any problem or abnormality in any of the aforementioned eye structures can be spotted. For example, an anterior chamber reaction is indicative of the presence of an intraocular inflammation; whereas the presence of cells and flare in aqueous humor is abnormal since the aqueous humor is normally clear (Black, Hawks, & Keenes, 2001). Conclusions Consequently, the abovementioned facts relevant to ocular assessment can be applied in implementing nursing management for the patients, thereby paving the way towards desirable...
