CHOROID
In the context of the eye:
Choroid Layer: The vascular layer of the eye that lies between the retina and the sclera, providing blood supply and nourishment to the retina.
Choroid Melanoma: A type of eye cancer that originates in the cells of the choroid layer.
Choroid Plexus: A structure within the brain that produces cerebrospinal fluid (CSF) and is not part of the eye.
Choroiditis: Inflammation of the choroid layer of the eye, often causing vision problems.
Choroideremia: A rare genetic disorder that leads to the degeneration of the choroid and progressive vision loss.
Choroidal Neovascularization: Abnormal blood vessel growth in the choroid, a condition often associated with age-related macular degeneration.
Choroid Angiography: A diagnostic procedure that uses dye and imaging to examine the blood vessels in the choroid.
In other contexts:
Choroid Coat of Birds: A specialized layer in the eyes of birds, reflecting and enhancing their vision, especially in low light conditions.
Choroid Cyst: A cyst that can form in the brain, typically found in the choroid plexus and not related to the eye.
Choroid Gland: An obsolete term for the choroid plexus, a brain structure responsible for cerebrospinal fluid production.
Choroid Plexus Papilloma: A type of brain tumor originating in the choroid plexus.
Choroid Veins: Veins within the choroid layer of the eye responsible for draining blood away from the eye.
Choroid Connective Tissue: The tissue that provides support and structure to the choroid layer in the eye.
Choroid Plexus Carcinoma: A malignant tumor that can develop in the choroid plexus of the brain.
Choroid Plexus Cyst: A fluid-filled sac in the choroid plexus of the brain, often present from birth and usually benign.
Choroid Tubercle: A small, rounded projection found on the body of the first cervical vertebra (C1), unrelated to the eye.
Choroid Fissure: A developmental feature in embryology, forming the boundary between the optic stalk and optic cup in eye development.
Choroid Glioma: A type of brain tumor that occurs in or near the choroid plexus.
Choroid Meningioma: A rare type of brain tumor that arises from the arachnoid cells on the surface of the choroid plexus.
Choroid Plexus Hemorrhage: Bleeding that can occur in the choroid plexus of the brain, often in premature infants.
