Correction regarding Ophthalmoscopy
The direct ophthalmoscope (hand held) is an instrument about the size of a small flashlight (torch) with several lenses that can magnify up to about 15 times.This type of ophthalmoscope is most commonly used during a routine physical examination. The pan-ophthalmoscope has a larger primary lens with a variable focusing, allowing for a wider field-of-view.
An indirect ophthalmoscope, on the other hand, constitutes a light attached to a headband, in addition to a small handheld lens. It provides a wider view of the inside of the eye. Furthermore, it allows a better view of the fundus.An indirect ophthalmoscope can be either monocular or binocular. It is used for peripheral viewing of the retina.
