Choroidal Thickness

Choroidal thickness refers to the measurement of the choroid, a layer of blood vessels located between the retina and the sclera (the eye's white part). This layer supplies nutrients and oxygen to the retina, which is essential for good vision. The thickness of the choroid can vary due to factors like age, eye health, or disease. Advances in imaging technologies, such as optical coherence tomography (OCT), allow doctors to measure this thickness accurately. Monitoring choroidal thickness helps in diagnosing and managing eye conditions like age-related macular degeneration and others that affect vision.
