| Not exactly Judy...but kinda close Dropsy is nothing more than the visible signs caused by swelling within the body...fluid retention. The fluid retention can be caused by a number of factors bvut without those factor(s) being addressed quickly, it will lead to a systemic infection and the death of the Koi.
The fluid retention in and of itself can be caused by bacteria already setting in and effecting the kidneys or other internal organs and thus effecting the osmotic balance of the Koi (ability to displace body fluids). The first syptom is typically the bulging of an eye (or possibly both eyes). Its at this stage that increasing the salt level in the pond (after ruling out parasites through scrape and scope) by .3%, the Koi's own immune system may be able to repel any bacteria that is invading. If the eye does not pull back in within 3-5 days, immediate antibiotic injections should be started. Typically, its at this point in time that the obvious signs of "Dropsy" begin to appear, swollen fluid pockets under the scales which make the scales "protrude". This is when it gets "delicate". At this stage, typically, the systemic infection has set in an now kidney and liver function is affected. Although antibiotics are a "must" at this point, antibiotics are also tough on the kidneys and liver, an area already adversly effected. Over dosing with antibiotics WILL have an adverse effect so special care must be given in correct doasges...a dosage that can still even have an adverse effect, To help the Koi displace the fluids, each of the fluid pockets should be "lanced" with a sterile scaple or even exacto knife (with the Koi knocked out of course). ThenThe hand should be placed over the top of the Koi with fingers on one side and thumb on the other. Firmly run the hand down the Koi from front to back and the fluids will be displaced through the previously slit skin areas between the scales. Some of this fluid may actually "shoot" out. This process should be done at the time of each inbjection and as needed (when pockets appear) afterwards until healed.
"Dropsy" was once thought of as "incurable". The process outlined above, when caught early enough has about a 60-75% chance of success.
