The most common cause of fluid behind the eyes is Grave's disease, while other possible causes include kidney or liver disease, according to a registered nurse at justanswer.com. Graves' eye disease is an autoimmune disorder that causes tissues around the eyes to swell, notes Thyroid Foundation of Canada.
Graves’ eye disease occurs in about half of patients with Graves’ hyperthyroidism who experienced eyelid changes, explains Thyroid Foundation of Canada. The condition results in red, painful and watery eyes, especially when exposed to wind or sunlight. Other symptoms of Graves’ eye disease include bulging eyes, blurred vision and decreased color vision.
Chronic kidney disease occurs when kidney function gradually decreases over time, according to the National Kidney Foundation. As the disease progresses, waste can accumulate in the blood, causing symptoms such as anemia, weak bones and nerve damage. Kidney disease can have a variety of causes, including diabetes, high blood pressure, glomerulonephritis and other disorders. If untreated, the condition can lead to kidney failure, which is life-threatening.
Chronic liver disease occurs when liver tissue is gradually destroyed over time, notes Johns Hopkins Medicine. The condition can be of two types, cirrhosis or fibrosis, with fibrosis often being the result of cirrhosis. Cirrhosis of the liver is caused by hepatitis, drug use, autoimmune disease or other conditions, resulting in various symptoms, including ascites, abnormal nerve function, vomiting blood and hair loss.
