Q. what is "pulmonary edema" and what are the risks? my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it! A. pulmonary edema occurs when, lets say, your heart left ventricle stops working properly and your right ventricle works fine. that means your lungs getting lets presume- 1 liter of blood -but your left ventricle can pump out of it only 990 ml. that means you have high blood pressure in your lungs and fluid comes out of blood vessels and fills your lungs, making it harder and harder breathing.
Another Cochrane Review examined the effectiveness and safety of two intravitreal steroid treatments, triamcinolone acetonide and dexamethasone , for patients with from CRVO-ME.  The results from one trial showed that patients treated with triamcinolone acetonide were significantly more likely to show improvements in visual acuity than those in the control group, though outcome data was missing for a large proportion of the control group. The second trial showed that patients treated with dexamethasone implants did not show improvements in visual acuity, compared to patients in the control group.
There is a constant balancing act that takes place within your body. When it comes to the levels of salt maintained in the body, the kidneys along with a number of hormonal and physical factors regulate the amount of salt retained and removed from the body. Your diet will determine the amount of salt you take in and the kidneys then control the amount of salt excreted via the urine. In case you suffer from medical conditions such as heart disease, diabetes or any type of kidney problems, there is a decrease in the blood flow to the kidneys. In response to this decrease, the kidneys start retaining more salt to maintain the fluid balance in the body. This results in water retention and edema. There are two main types of edema that can affect a person – pitting and non-pitting. When you press down on a swollen area and the indentation is left behind on the skin, it is known as pitting edema. Non-pitting edema does not cause any such indentations.
