Choroid: Unsung Workhorse of the Eye

Jay Chhablani, MD

An often understated yet critically important part of the eye is the choroid. Understanding what the choroid is and its role in vision can one day help researchers and clinicians better diagnose and treat commonly known diseases of the eye, such as macular degeneration. What is the Choroid? The choroid is the most vascular layer of the eye. It supplies nutritional support to photoreceptors (the most critical cells in the retina) and plays a vital role in vision. Its function is very well established in vision-threatening diseases such as age-related macular degeneration, central serous chorioretinopathy, and pachychoroid diseases. However, understanding

And those bacteria actually stimulate an immune response that protects the eye from infection,” stated Dr. St. Leger. “We also know that bacteria stay on the eye
