MEMBRANA CAPSULOPUPILLARIS Meaning and
Definition
-
The term "membrana capsulopupillaris" refers to a specialized structure located within the eye known as the "pupil membrane." The pupil membrane is found in the area surrounding the pupil, which is the central black opening of the iris responsible for controlling the amount of light that enters the eye.
The membrana capsulopupillaris, also known as the "pupillary membrane," is a thin layer of tissue that forms during embryonic development. It typically starts as blood vessels that grow into the iris, but as the eye matures, these vessels regress and are replaced by connective tissue. The remaining remnants of these blood vessels form the membrana capsulopupillaris.
The pupillary membrane is present in the eyes of many mammals, including humans, but is typically not functionally active in adults. It serves a crucial role during fetal development by providing nourishment to the developing structures of the eye. However, as the eye matures, the membrane gradually regresses, becoming non-functional and often disappears completely, usually before birth.
In rare cases, remnants of the membrana capsulopupillaris may persist into adulthood and can be recognized as small strands or veils in front of the pupil. These remnants are considered to be anatomical variations and are not typically associated with any visual impairments or health concerns.

Etymology of MEMBRANA CAPSULOPUPILLARIS
The word "membrana capsulopupillaris" is a combination of Latin and Greek roots.
- The Latin word "membrana" means "membrane" or "thin layer".
- The Latin word "capsula" means "small box" or "capsule".
- The Latin word "pupilla" means "pupil" or "little doll".
- The Greek word "-aris" is a suffix used to denote "belonging to".
Therefore, "membrana capsulopupillaris" can be translated as "the membranous capsule belonging to the pupil". This term is commonly used to refer to the thin membrane that surrounds and encloses the pupil in the eye.
