Essay on The Human Eye

The human eye is one of the most complex organs in the body that can be easily taken for granted. It is an organ that is susceptible to various disorders such as glaucoma, which can eventually lead to impaired vision and blindness. Glaucoma is one of the leading causes of blindness. Currently, there are no cures for glaucoma. There are, however, treatment options such as medications, laser procedures and surgery to slow the effects of glaucoma to prevent the progression of blindness from occurring. Throughout this paper, various treatments for glaucoma will be presented as well as the best nursing practices centered on evidenced based research.

Glaucoma occurs when there is optic nerve damage due to elevated increased ocular pressure. There are several classifications for glaucoma. The two most common classifications are open-angle and angle-closure glaucoma. The open-angle glaucoma is referred, as the chronic glaucoma, where aqueous fluid stays in the eye and builds up, increasing intraocular pressure. In angle closure glaucoma, the drainage pathway is inhibited where the symptoms arise rapidly causing blurred vision, which will then require emergency intervention (Smeltzer, Brunner, & Suddarth, 2010, p.1768-1769). For treatment, doctors’ first choices are pharmaceutical medications. The eyes are very sensitive to many medications. Patients who are diagnosed with glaucoma are prescribed with eye drop medications. Initially prostaglandin analogs such as Xalatan® (Latanoprost) is prescribed. According to Watkinson (2010, p.20), she mentions how Xalatan® has low side effects and helps the aqueous fluid pass through the ciliary body decreasing pressure. The next set of medications given is topical beta-blockers such as…

…ision. Nurses can then refer patients to rehabilitation services and home care to help them with their ADLs. (Wu, Guo, Xia, Lu, & Xi, 2011, p.806). Losing vision is a horrific thought and to process the fact that blindness is occurring needs tremendous support from family and friends.Glaucoma has affected many people throughout the world. The treatment for glaucoma has improved tremendously becoming effective and safer. Though there are many options for treating glaucoma there is still no cure to prevent and completely eradicate the disease. Medications are still the best option for treating and controlling glaucoma. Nurses are encouraged to keep patients educated and aware of how to deal with the illness. The eye is such a vital part of human life and to let it deteriorate on its own without cause is something researchers should strive to resolve.
