Exudative retinal detachment

Exudative retinal detachment develops when fluid collects in the subretinal space. The subretinal space between the photoreceptors and the retinal pigment epithelium is the remnant of the embryonic optic vesicle. In the developed eye the subretinal space is of minimal size, but it can reopen under pathological conditions that disrupt the integrity of blood-retinal barrier. Inflammatory, infectious, infiltrative, neoplastic, vascular, and degenerative conditions may be associated with blood-retinal barrier breakdown and the sequential development of exudative retinal detachment. We elaborate on the pathogenesis and the differential diagnosis of exudative retinal detachment and specifically discuss the spectrum of diseases associated with exudative retinal detachment in uveitis clinics.
