Why has my cousin's iris changed from black to light brown?

---

My cousin does not use contacts or anything. Neither does she have any diseases, atleast not that i'm aware of. But over 3 years her iris has changed from black to light brown almost able to see the iris pupil. Why does it happen, what causes it? Is it a symptom?
i think it is somehow normal, i think it's possible because of gene factor or natural causes  (+ info)

My son is 6 months old and recently I noticed there is a very faint blue ring around his iris.?

---

This is a ring around the iris of only one eye. I tried googling an answer but I didn't get a real answer. I am also not sure what google search terms I should use since the colors of the ring are based on different eye diseases or cancers. If anyone can point me in the right direction I would deeply appreciate it. Thanks!
I wouldn't worry about it. I have had quite a few friends with different color eyes or blotches of hazel or blue or brown. Just see whats going on. If you do worry about it. Make an appointment with the doctor  (+ info)

What does it mean if you have gray rings in the outer edge of your iris?

---

My eyes are normally green, but today I noticed the edge of the colored part is somewhat gray. I'm not taking any type of medication, but if it matters, I haven't really slept much in the past week. My friend told me it could be a copper buildup due to some disease, but he didn't really know much.
It could be arcus senilis or arcus juvenilis. In older people it is usually just a cosmetic event. In younger people it may indicate cholesterol problems. It would be a good idea to have it checked out.

"However, a similar discoloration in the eyes of younger adults (arcus juvenilis) is often associated with high blood cholesterol. Such a finding in younger individuals warrants further evaluation by a doctor."  (+ info)

What causes the iris of the eye to turn yellow?

---

My eyes are naturually ocean blue, i recently discoevered that the tops of the iris in each eye, more the left than right have turned yellow just above the pupil in normal state. Im not talking about the small yellow lines most ppl have, an actual part of the blue has turned yellow. i've tried to look everywhere to find out whats going on. i know it isnt jaundice because the white of my eyes are not effected. any help would be much appreciated. thanks, Mike.
Mike,
There are several possible causes of iris color change. Inflammation inside the eye; loss of the some of the pigment
making it look yellow or dull; circulation changes to the iris like diabetes and cholesterol.

Any of these possible causes need to be examined by an eye doctor, Board Certified Optometrist or Ophthalmologist.

If it is a change that has happened recently, then you should get it checked soon.  (+ info)

What are the designs in the iris of the eye called?

---

In most people with lighter colored eyes you can see what looks like diamond shapes or fibers in the iris (the color part of the eye). What are these fibers or designs called and what are they. Also I heard that they can be caused by injuries. Sounds false?
Why do some people have more crypts then others?
The variations of the iris strands are called crypts.

EDIT: It is simply related to the fact that all people are different. There isn't anyone else in the world that looks like me. Likewise, there isn't anyone else in the world who has the same iris architecture as I do. Some security technology actually employs iris architecture analysis.  (+ info)

What could cause or be related to holes in the iris of the eye?

---

An eye doctor told me I have numerous microscopic holes in my iris. I'm going back in for more tests, but I can't find anything on the internet that sounds particularly linked to this.
Here is a link I have found that lists a few things that can cause this.

How can you get contacts that do not show your iris from underneath?

---

I've noticed that with contacts people can see the actual colour of your eye because the pupil "hole" is big. How can you purchase contacts that cover your entire iris without showing the original colour. I've noticed Paris Hilton's contacts look very realistic because her real eye colour is never apparant. I never knew her eyes were dark brown until it was on the news.

What could a white spot on my iris be diagnosed as?

---

I have a small white spot on my iris that seems to have developed quite suddenly; i only noticed it this morning. I'm 16 years old so i doubt it has anything to do with aging. It's not affecting my vision or causing pain. If anyone has any ideas about what it could be I'd appreciate it.
Are you sure it is in the iris and not on the cornea over the iris?

The eye is not something to watch and wait. If you have a problem, you should get prompt medical attention.  (+ info)

What diseases would have the symptom of coughing up blood or blood in the phlegm?

---

This is not a symptom of my own so please don't tell me to go to the doctor, it is for a piece of work I have to do for College.

If you could tell me the name of a disease/ diseases that cause this, preferably not consumption or TB, a little about it and other symptoms it would be a massive help!
If you could also include treatment options and how serious a disease it is that would also be fantastic!



Hope you can help! Thanks!
First: spitting up blood is clinically known as: HEMOPTYSIS (bloody sputum, spit)
Yes, pneumonia is the most likely, but......
The following is from my medical e-book (I'm a nursing student)

"Blood in the sputum (hemoptysis) is most often seen in clients with chronic bronchitis or lung cancer. Clients with tuberculosis, pulmonary infarction, bronchial adenoma, or lung abscess may have grossly bloody sputum."
Also the end stage of cycstic fibrosis will present with hemoptysis.

a biggie in the hospital is:
PULMONARY EMBOLISM
PATHOPHYSIOLOGY
A pulmonary embolism (PE) is a collection of particulate matter (solids, liquids, or gaseous substances) that enters venous circulation and lodges in the pulmonary vessels. Large emboli obstruct pulmonary blood flow, leading to decreased systemic oxygenation, pulmonary tissue hypoxia, and potential death. Any substance can cause an embolism, but a blood clot is the most common.

Pulmonary embolism is the most common acute pulmonary disease (90%) among hospitalized clients. In most people with PE, a blood clot from a deep vein thrombosis (DVT) breaks loose from one of the veins in the legs or the pelvis. The thrombus breaks off, travels through the vena cava and right side of the heart, and then lodges in a smaller blood vessel in the lung. Platelets collect with the embolus, triggering the release of substances that cause blood vessel constriction. Widespread pulmonary vessel constriction and pulmonary hypertension impair gas exchange. Deoxygenated blood shunts into the arterial circulation, causing hypoxemia. About 12% of clients with PE do not have hypoxemia.

Pulmonary embolism affects at least 500,000 people a year in the United States, about 10% of whom die. Many die within 1 hour of the onset of symptoms or before the diagnosis has even been suspected.

For clients with a known risk for PE, small doses of prophylactic subcutaneous heparin may be prescribed every 8 to 12 hours. Heparin prevents excessive coagulation in clients immobilized for a prolonged period, after trauma or surgery, or when restricted to bedrest. Occasionally, a drug to reduce platelet aggregation, such as clopidogrel (Plavix), is used in place of heparin.



A smaller one that popped up in the book:
GOODPASTURE'S SYNDROME
PATHOPHYSIOLOGY
Goodpasture's syndrome is an autoimmune disorder in which autoantibodies are made against the glomerular basement membrane and neutrophils. The two organs with the most damage are the lungs and the kidney. Lung damage is manifested as pulmonary hemorrhage. Kidney damage manifests as glomerulonephritis that may rapidly progress to complete renal failure (see Chapters 74 and 75). Unlike other autoimmune disorders, Goodpasture's syndrome occurs most often in adolescent or young adult men. The exact cause or triggering agent is unknown.

COLLABORATIVE MANAGEMENT
Goodpasture's syndrome usually is not diagnosed until serious lung and/or kidney problems are present. Manifestations include shortness of breath, hemoptysis (bloody sputum), decreased urine output, weight gain, generalized nondependent edema, hypertension, and tachycardia. Chest x-rays show areas of consolidation. The most common cause of death is uremia as a result of renal failure.

Spontaneous resolution of Goodpasture's syndrome has occurred but is rare. Interventions focus on reducing the immune-mediated damage and performing some type of renal supportive therapy.

What diseases can you get from cutting yourself with a rusty knife?

---

This is a question from a growing nurse. I've always wondered if you really can get a disease from a rusty knife or any rust and what kind of diseases you can get.
staph aureus and staph epidermidis are commonly found on the skin and are responsible for
most infected wounds. methicillin resistant staph aureus (MRSA) is becoming a serious
problem. tetanus (clostridium tetani) is also a possibility but is usually not a problem with superficial
cuts that bleed a lot. infected wounds not treated properly can become gangrenous (clostridium
perfringens). clostridium bacteria are anaerobic which means that require a lack of oxygen to
grow. poor circulation or elevating an infected foot may lead to gangrene due to the lack of oxygen
in the infected area. if a person touches the cut with unclean hands, e. coli could infect the wound.  (+ info)
