CHOROIDAL DISEASE Meaning and
Definition
-
Choroidal disease refers to a group of medical conditions that affect the choroid, a layer of tissue located between the retina and the sclera (white part of the eye). The choroid plays a crucial role in supplying blood and oxygen to the retina, which is vital for normal vision.
One common choroidal disease is called choroidal neovascularization (CNV), characterized by the abnormal growth of new blood vessels beneath the retina. This condition can lead to vision loss, as these blood vessels can leak fluid and blood, causing damage to the retinal tissue. Another choroidal disease is choroidal melanoma, a rare but potentially malignant tumor that develops from pigment-producing cells in the choroid. Choroidal melanoma can lead to vision impairment and ultimately poses a risk of spreading to other parts of the body.
Other choroidal diseases include choroidal hemangioma, a benign tumor made up of blood vessels; central serous chorioretinopathy, characterized by the accumulation of fluid beneath the retina; and polypoidal choroidal vasculopathy, which involves the development of abnormal blood vessels in the choroid.
Diagnosis of choroidal diseases typically involves a comprehensive eye examination, including visual acuity tests, dilated fundus examination, and ocular imaging tests such as fluorescein angiography and optical coherence tomography. Treatment options vary depending on the specific disease but may include medication, laser therapy, photodynamic therapy, or surgery. Regular monitoring and early intervention are crucial to preserve vision and prevent further complications.

Etymology of CHOROIDAL DISEASE
The word "choroidal" comes from the Greek word "choroeides", which means "like a membrane". The term "choroidal" refers to the choroid, which is a layer of tissue located in the back of the eye. It provides oxygen and nutrients to the retina.
The word "disease" comes from the Old French word "desaise", which means "lack of ease" or "discomfort". It was derived from the Latin word "dis-" meaning "lack of" and "aestimare" meaning "to estimate" or "to value". In this context, "disease" refers to an abnormal condition or disorder affecting the choroid.
