As a retina specialist, my specialty niche is disease pertaining to the retina and vitreous. The retina is the light sensitive tissue which lines the inside of the eye.
The vitreous is the gel like substance which fills most of the eye in the posterior chamber (that portion of the eye behind the iris and lens).
What Does the Vitreous Do?
The vitreous is critical to embryonic development, that is, it’s part of the development of the eye.
