HEALTH EXAMINATIONS
The eye is the only organ in the human body which
allows direct observation of the blood vessels
without surgical intervention. This is why many
vascular conditions such as high blood pressure
and diabetes are first highlighted by an optometrist.
Some of the health assessments tests used during
the eye examination include;
SLIT-LAMP BIOMICROSCOPE
This instrument allows a detailed inspection of
the external eye and is helpful for examining
any signs of cataract and any disease of the
lids, lashes, tear film, cornea, conjunctiva
and iris.
