Patient's question:
Eyes see things blurry. It has been severe in the past year, and now the right eye has almost no vision, while the left eye has 0.5 vision. When I went to the hospital, they said it was old retinal disease, and there was also a slightly severe cataract.Doctor's answer:
The cornea, iris, lens, and other structures in front of the eye are defined by ophthalmologists as the anterior segment of the eye, while the vitreous body, retina, choroid, and other structures behind the eye are defined as the posterior segment of the eye. The bottom of the posterior segment is collectively referred to as the fundus.
