 Ophthalmoscopy
An
ophthalmoscope is an instrument used to examine the retina
and vitreous. Ophthalmoscopy
requires dilating the pupils with drops to give the doctor the best view inside
the eye.
There
are two types of ophthalmoscopes: direct and indirect. The direct is
a hand-held instrument with a battery powered light source. It also has a
series of lenses that can be dialed in to focus the doctor’s view of the
retina. The direct ophthalmoscope is useful for examining the central
retina.
The indirect ophthalmoscope can be used to examine the entire retina. This instrument is worn on the doctor’s head. While looking through the instrument’s magnifying glasses, a special lens is placed in front of the patient’s eye, allowing the doctor to see the retina clearly.
