Exudative pleural effusions, by contrast, are caused by alterations in " local " factors that influence the formation and absorption of pleural fluid ( e . g ., bacterial pneumonia, cancer, pulmonary embolism, and viral infection ).

Before the causative mutation was identified, mutations were sought from the Wnt signalling pathway because its components were known to be responsible for Norrie disease and familial exudative vitreoretinopathy, which share features of the eye phenotype but not the brain or systemic abnormalities.

For example, signs of retinopathy that reflect the exudative stage, such as retinal hemorrhage or microaneurysm, may be seen in eyes that do not have features of the sclerotic stage, The exudative signs are nonspecific, since they are seen in diabetes and other conditions.

A case of Coats'disease, showing total exudative retinal detachment, and subretinal exudate containing cholesterol crystals ( H & E ) . Microscopically, the wall of retinal vessels may be thickened in some cases, while in other cases the wall may be thinned with irregular dilatation of the lumen.

There are three stages : exudative, when there is an increase in pleural fluid with or without the presence of pus; fibrinopurulent, when fibrous septa form localized pus pockets; and the final organizing stage, when there is scarring of the pleura membranes with possible inability of the lung to expand.

Nonetheless, the " exudative " is reminiscent of the differences in water loss during cooking in the study I cited above, so it might be the extreme case of a broader phenomenon . ( but I don't know that ) talk ) 17 : 25, 6 April 2016 ( UTC)
