Retina
The eye is like a camera with a lens in front and a film (retina) at the
back. The retina is located approximately two centimeters behind your pupil. It
is shaped like a small cup. The retina converts the ocular image into a signal
that is sent to the brain. The central part of the retina, called the macula,
is used for straight-ahead vision and what is in your direct line of sight.
A healthy macula is crucial for tasks involving fine vision such as reading,
recognizing faces and distinguishing things. The area surrounding the macula helps
in mobility and in seeing from the 'corner' of the eye, though it is not useful
for fine work. The retina is connected to the brain by the optic nerve. Blood
is supplied to the retina and the optic nerve by blood vessels that maintain the
health of these tissues. In front of the retina is the vitreous cavity, which
is filled with a gel-like substance, called the vitreous.
Diseases of
the retina, the vitreous, and the optic nerve can cause serious vision problems.
Fortunately, most of them can now be managed satisfactorily with modern methods
of diagnosis and treatment.
This link will help you understand
the treatment of diseases of the retina and the vitreous. Remember, early diagnosis
and prompt and appropriate treatment can result in a better outcome.
