This is the accumulation of excess water in the body cavity or tissues. It is a general term used to describe body swelling or oedema of the skin. The latter causes the scales to protrude and give the body a 'pine cone' appearance. It is frequently associated with protrusion of the eyes due to fluid and commonly called 'pop-eye'. Dropsy is not a disease in itself and may result from damage by bacterial or virus infections, organ failure or tumours. There is no effective treatment for most cases.
