Our senses are very important because they allow us to see, hear, smell, taste, and touch so we can experience the life around us. The eye is the most important sensory organ. It is the organ of vision, and it is very sensitive. Therefore, we should protect our eyes from diseases; such as, macular edema, cataract, macular dry enteration, and red eye. We have all experienced red eye at least once in our life, affecting one or both eyes. That makes us wondering, what is Red eye? What can cause it? And how can we treat the causes?. Red eye is a cardinal sign of ocular inflammation. It occurs when the vessels in the eye become swollen or irritated. Red eye occurs as a consequence of blepharitis, dry eye syndrome, or conjunctivitis (med scape,2012).
First, Red eye occurs due to conjunctivitis disease. Conjunctivitis, which is usually called pink eye, is an infection or inflammation in the eye area. The effect of viruses, bacteria, and allergies, is pink eye disease. For example, Viral conjunctivitis is the result of infection from herpes simplex virus (HSV), varicella zoster virus (VZV), or human immune deficiency virus (HIV). It can be transfer from one person to another. In addition, Bacterial conjunctivitis has common causes including staphylococci, streptococci, gonococci, and Chlamydia. Also, Allergic conjunctivitis may be divided into five major subdivisions. They are Seasonal allergic conjunctivitis (SAC), perennial allergic conjunctivitis (PAC), Vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC), and giant papillary conjunctivitis (GPC). There are a lot of inflammation causes; therefore, there are a lot of symptoms including redness in the white of the eye or internal eyelid, enlarged amount of tear...

...er, it has several symptoms including Foreign-body sensation, itching, irritation, burning, and excessive tearing. You can protect your eyes from getting dry eye syndrome by preventing it from many risks, such as; dry, hot, or windy climates, high altitudes, air-conditioned rooms, and cigarette smoke (medscape, 2013).
To sum up, As a result of dry eye, pink eye, and blepharitis, red eye may occur. Red eye is a common disease that affects our ability to see. furthermore, there are many symptoms of dry eye, pink eye, and blepharitis; such as; redness in the white of the eye or internl eyelid, increased amount of tears, and Foreign-body sensation. Now you can prevent your eye from getting red eye by using lubricant eye drops, Washing your hands regularly, Adding tears, conserving tears, increasing tear production, and sometimes you will need the help of doctor.
Gas in 1968 described Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE) as being a condition that caused acute and rapid loss of central vision due to multiple pale lesions at the level of Retinal pigment epithelium (RPE) in the posterior pole. (1) It is a self-limiting condition which recovers spontaneously over a three weeks period leaving residual pigment epithelial alterations.(2) The typical features in acute phase include cream colored placoid lesions at the level of RPE, early hypofluorescence and late hyperfluorescence of the lesions on Fundus fluorescein angiography (FFA).(2) It is usually followed by a viral flu like prodrome in 1/3 of the patients. Neurological manifestations of APMPPE include Headaches being commonest while others are paraesthesias, vertigo, psychosis and more severe complications, Cerebrospinal fluid pleocytosis stroke and cerebral vasculitis.(3, 4) Association of APMPPE with systemic Vasculitis in the patients with positive perinuclear antineutrophil cytoplasmic antibody has been reported.(5, 6) Other systemic inflammatory diseases suggesting an underlying immune mediated or an inflammatory mechanism include erythema nodosum,(7-9) juvenile rheumatoid arthritis,(10) thyroiditis,(11, 12) nephritis,(5, 6, 13) ulcerative colitis(14) and Adenoviral infections(15) . Many granulomatous diseases have documented associations with APMPPE, including Wegener’s granulomatosis,(16-18) Pulmonary tuberculosis(19) and Sarcoidosis.

...your skin the way it is it may be too painful to move. You can also be impaired by your hearing or eye sight which is caused by the skin on your eyes or ears. One of the worst issues you may possibly gain from having Ichtyosis Vulgaris is having psychological problems due to the abnormal appearance of the skin. With the way you look and all these patches of dry skin on you it’s possible that it can mentally destroy you and eat at you bit by bit in how you see yourself and how people see you.
The pupil is where light can enter the eye. The iris is in control of the amount of light that actually goes through. The light reaches the lens, which alters the shape of it so the eye can focus on it. Light reaches the retina, which consists of cones and rods. Colors are saw differently based on their implied meanings, which to various psychological functions. The cones are responsible for color. The color red would have such an effect on people’s perception of others based on their production of affect, behavior and cognition. A sociocultural theorist would explain this effect by indicating that the associations with the color red are normal. When a student sees a plethora of red marks on their paper, they automatically think they failed the assignment. Biological theorist would best explain this theory by saying the color red helps them survive or reproduce. A man may be attracted to a woman more because she is wearing red. This attractiveness could cause him to find his mate and eventually reproduce. A behavioral theorist would explain this effect by saying the color red provokes pleasure and avoids pain. A person can associate red with romance and
The eye is an important sensory organ for vision which houses a sensitive optical apparatus in a relatively isolated tissue compartment. Eye is essentially made of three layers: (1) sclera, (2) uveal tract, and (3) retina with each of these layers performing intricate duties which ensure proper functioning of the eye.
An itchy eye is an issue that is very common. Itchy eyes means an unpleasant itchy sense in the vicinity of the eyes, as the name implies. The situation may be recurring for those that often touch or rub their eyes. For immediate relief, it is possible to look at some simple-to-follow treatments that are natural. Several treatments use easily available ingredients out of your kitchen.
Glaucoma is a common and important health problem. It is one of the leading causes of blindness in Western Society (Hoskins & Kass, 1989). It is responsible for ten percent of all blindness in the United States and continues to be the second or third most common cause of blindness in the world (Bunce, Fraser, & Wormald, 1999). It is estimated that two million people in the United States have been diagnosed as having glaucoma. Glaucoma is known to affect about two percent of Caucasians beginning at the age of 40 with an increasing risk for those over the age of 60. This risk is especially high if a member of the family has glaucoma or diabetes. Further, there is a higher risk of a glaucoma diagnosis for African Americans over the age of 40.
Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain. The macula is a small extra-sensitive area within the retina that gives central vision. It is located in the center of the retina and contains the fovea, a small depression or pit at the center of the macula that gives the clearest vision. The blind spot is at the exit point of the optic nerve, at this point there are no rods or cones, and so all the light directed here are of no use. Eye color is created by the amount and type of pigment in the iris. Multiple genes inherited from each parent determine a person’s eye color. Though the eye is such a wonderful organ, it is also prone to diseases, infections, and other problems that could be minor or major, and could lead to blindness or poor
Many signs include a "white pupil," also known as leukocoria. Retinoblastoma can occur in either one or two eyes (Paul T. Finger, Pg. 1). This abnormal white pupillary reflex is sometimes referred to as a cat's eye reflex. Another sign of retinoblastoma is a crossed eye (Ambramson, Ch3). Leukocoria doesn't always end up as being retinoblastoma, it can even result in: congenital cataract, Toxocara canis, Coat's disease, and persistent hypertrophic primary vitreous (PHPV) (Finger, Pg.2). Retinoblastoma occurs when there's a mutation or deletion of the q14 band of chromosome 13 (Finger, Pg. 1). Symptoms can be painful if not treated quickly. Some include a red, painful eye, swelling of the surrounding eye, poor vision, dilated pupil, even extra fingers or toes, and retardation (Ambramson, Ch3).
The symptoms of eye contact come in two forms and at different times, ocular symptoms within 4 to 6 hours and corneal edema within 1 hour. Symptoms are as follows: pain, photophobia, blepharospasm, lacrimation, conjunctivitis, corneal lesions, blistering of the eyelids, and infections. Short term to long term effects that could occur is blindness though this may clear up with 10 days.
Measles Measles is a highly contagious disease. It is caused by an RNA virus that changes constantly. Measles symptoms usually include a bad cough, sneezing, runny nose, red eyes, sensitivity to light, and a very high fever. Red patches with white grain like centers appear along the gum line in the mouth two to four days after the first symptoms show. These patches are called Koplik spots because Henry Koplick first noticed them in 1896.
Bacterial Conjunctivitis, commonly known as “pink eye”, is one of the most well-known and treatable eye infections for both children and adults. The name was chosen because it is an inflammation of the conjunctiva. The conjunctiva is the clear membrane that covers the white part of the eye and lines the inner surface of the eyelids. It is commonly called “pink eye” because of the red color of the eye from irritation and was described as such.
The patient is a 43 year-old female insurance sale agent who came to the clinic for annual eye examination. She complained from symptoms of ocular irritation and burning when she wakes up in the morning. She felt ocular dryness in the afternoon and the eyes look red. She has also noted different height of her eyelids when putting make-up on. She denied significant problems with driving, TV watching, computer use or reading. She also denied flashes, floaters or diplopia. The patient was myopia with no prior eye surgeries, previous history of eye trauma, amblyopia or strabismus. She did not use any medication. The past ocular family history was negative. Social history was negative, too.
Have you ever wondered why the sky is blue. Often times I find myself looking up on a clear day, pondering over that question? Why isn’t it green, or red or pink for even that matter. Every day, the human eye blinks more than 23,00 times. The human eye is a complicated organ that performs one of the most important tasks for our body. There are many questions about the eye however. What function do they perform? What happens if we don’t take care of them? How exactly do they work together to help us form images? Exactly how far can they human eye see?
In its more common from, color blindness is the inability to distinguish between reds and greens.Persistent headaches, blurred vision, and painful inflammation of the eyelids are symptoms that may indicate serious eye disorders. Particles lodged in the eye should be removed without delay. Glasses are prescribed to strengthen vision and to reduce strain and fatigue.
