Dry Eye Condition Essay

Other factors include family history, medical conditions, which include diabetes, high blood pressure, heart conditions and physical injury of the eye. Other eye-related risk factors are eye anatomy, corneal thickness and optic nerve appearance. Conditions such as retinal detachment, eye tumors, and eye inflammations, high amounts of nearsightedness may also induce glaucoma.

contact lens have risk of eye infection that are caused by herpes, bacteria, and fun gus. In addition, symptoms of eye infection has include blurry vision, unusual redness of eyes, painful of eyes and tearing of eyes, so it causes loss of vision to blindness. Thus, some people have symptoms of eye infection who people must have to meeting

Diabetic retinopathy is caused by blocked blood flow to the eye, causing ischemia or increased permeability of the blood vessels in the eye. Macular edema is caused by swelling in the eye due to the increased permeability, and both of these are common causes of vision loss of those with diabetes. Some factors that can be seen in the retina from a fundoscopic exam that can cause these issues (all of which were detected in our patient), are micro-aneurysms, intrarenal hemorrhages, and hard exudates. All three of these can disrupt the blood-retinal barrier, causing issues with blood flow and swelling. Additionally, lipids and proteins both play important roles in the eye, and if there is improper breakdown of these molecules, they can make deposits in the outer layer eye. The more deposits (hard exudates) a patient has, the larger affect it can have on their vision.

Graves’ disease can cause multisystem syndrome known as thyrotoxicosis. This syndrome is the result of increased hormones produced by the excessive stimulation to the sympathetic nervous system. Diagnosis in elderly patients can be difficult to detect due to the symptoms being unclear and often mimicking aging. Also, other disorders can attribute to trouble of finding and pinpointing the disease (Weeks 35). Exophthalmos is a more severe yet common symptom observed within 20% to 40% of all patients with Graves’ disease. This is when excessive amounts of fluid accumulate behind the eyes. This causes inflammation within the tissues behind the eyes and edema occurs. The eyeballs tend to protrude out of the orbital sockets. This causes irritation, tearing and corneal abrasions. Also due to the protrusion of the eyes, the sclera above the iris becomes exposed not allowing the eyelids to cover the eye entirely (Weeks 35).

Your eyes can reveal quite a bit about your health, here are a few examples. One would be bug eyes which doctors call exophthalmos, it is a common sign of Grave's disease, a.k.a. overactive thyroid. In addition to the bug-eyed look, people with Grave's often experience weight loss, nervousness, and a rapid or strange pulse. A thin gray ring around your cornea, arcus senilis, often goes hand in hand with high cholesterol and triglycerides. It may also increase the risk of a heart attack, it is a recommendation for anyone with this condition to have a blood test to check for elevated blood lipids, especially anyone under 60. Cloudy eyes are another example, This is a cataract - a clouding of the lens inside the eye. The condition, which can

The tear layer has less effect on contact lens power, if lens is in perfect alignment onto the cornea. The degree of clearance of the lens enables the tear film to have a power effect on cornea/tear/lens system. Inadequate watery layer in the tear film causes dry eyes. As such the contact lenses become uncomfortable to wear.

Before I began writing this article, I purposefully put on mascara. The reason being that if I cried, my mascara would streak down my face. Of course, nobody wants that. Crying is one thing, but ruining your eye makeup is altogether unacceptable.

Keratoconjunctivitis Sicca, also known as Dry Eye Syndrome, is a commonly diagnosed condition in eye care clinics, especially among older adults (1). The condition occurs when the surface of the eye becomes irritated and the tear reflexes are not sufficient to wash the irritation away. The immune system is then activated to attack the irritation, and T-cells begin to release cytokines onto the ocular surface. Prolonged exposure to cytokines can cause damage to the tissues of the eye, including the lacrimal glands that are responsible for producing tears (2). The damage causes more inflammatory responses to be activated, causing a cycle that leads to reduced tear production and consequently the symptoms of Dry Eye Syndrome, including burning, redness, stinging, or a scratchy sensation in the eye (3). Since Dry Eye Syndrome is associated with an inflammatory response, it was hypothesized that a potential treatment for Dry Eye could involve disrupting the inflammatory cascade using a neuromodulator that inhibited a component of the inflammatory response mechanism.

The cornea is most significantly affected by the active metabolic pump in the endothelium. This layer of cells in the posterior of the cornea maintain the fluid pump to keep the cornea dry and clear through the metabolic pump which is activated by temperature and the sodium potassium ATPase enzyme. The cell density of this basement membrane is vital as it is 7500 cells/mm2 and decreases with age (Michael 2014). If this cell density reaches low levels of approximately 300-500 cells/mm2 then a corneal edema develops since the endothelium cannot maintain the pumping of the fluid and eventually floods the cornea which could be the cause of the corneal edema in the corneal epithelial layer (Michael 2014).

About two years ago, my husband's mother had a drooping eyelid (common symptom of diabetic retinopathy). Luckily my husband noticed that it was not normal and she

Eyes: Itching, pain and burning sensation, tearing, redness, swelling of the membrane and eyelids and sometimes irritation

Your doctor may perform a Schirmer test to evaluate for dry eye. They may also conduct tests for decreased secretion of saliva (salivary hypofunction).

Graves opthalmopathy is caused by an abnormal antibody attack on the thyroid gland which often results in over or under production of thyroid hormone. This same antibody can attack eye tissues and cause various eye symptoms (Shah, 2011).

Modernizing a thriving dermatology practice with patient-centric processes and services demands best-in-class technology that supports best practices throughout your organization. Selecting an electronic medical record (EHR) with flexibility to personalize forms and generate reports based on your needs is critical. Finding a best-fit EHR solution, one that is compatible with the unique needs of dermatologists, will position your team to reach your financial and patient outcome goals. These five tips will help you find a system that will grow with your practice and serve all stakeholders well.
