subretinal fluid
Fluid accumulation between the neurosensory retina and retinal pigment epithelium, often associated with intraocular tumors.
Full Definition
Subretinal fluid refers to the abnormal accumulation of fluid in the subretinal space, which is the potential space between the neurosensory retina and the underlying retinal pigment epithelium. In ocular oncology, subretinal fluid is commonly associated with intraocular tumors such as choroidal melanoma, choroidal metastases, and retinoblastoma. The fluid accumulation occurs due to disruption of the blood-retinal barrier or mechanical displacement of retinal structures by the tumor. The presence and extent of subretinal fluid influence visual symptoms and treatment planning, and may persist after tumor treatment.
Usage
Usage note: Often accompanies intraocular tumors; may indicate treatment response when it resolves.
