Infectious agents may be carried from elsewhere in the body and cause one or more foci of infection in the retina and less often in the choroid in one or…
Noninfectious inflammatory diseases of the retina can be isolated to the retina or be contiguous with its underlying structures, choroid and sclera, or with adjacent structures, optic nerve, vitreous, and…
