Other conditions that may cause excess fluid in the eye include:
Choroidal effusion - the buildup of fluid between the choroid, the sclera, and a layer of blood vessels on top of the retina.
A retinal tear - may cause fluid to accumulate, which can lead the retina to detach.
Chemosis - a swelling of the eye due to accumulation of fluid that is often caused by allergies or an eye infection.
