What is Retina?
Retina is a layer of nerve tissue that senses the light coming
into the eye and communicates this information to the brain.
The front part of the eye consisting of cornea and the lens
focuses light onto the retina. Acting like a film in a camera,
the retina captures the light and transmits it to brain where the
light is processed into recognizable images
What is Vitreous?
Vitreous is a gelatin like substance that fills the eye between
the lens and the retina. It is densely adherent to a circular
area adjacent to the lens called vitreous base. It is very lightly
adhered to retinal blood vessels and to area around the macula
on retina and the optic nerve head. Vitreous is like solid
Jell-O at the time of birth and slowly degenerates with age
becoming more liquid. Vitreous acts as a reservoir for certain
nutrients and oxygen for retina but a definite role is not
known at this time. As this transformation happens, the
vitreous can separate from the back of the eye in a condition
called Posterior Vitreous Detachment or PVD. This usually
presents as flashing lights or floaters. This can be
accompanied by formation of retinal tears or development of
retinal detachment. Thus it is very important for anyone
developing symptoms of flashing lights or floaters get a
comprehensive eye exam by an eye specialist.
What is Macula?
Macula is central part of the retina that affords us the finest
vision. The center of this area called the fovea is the area that
allows us 20/20 vision.
