3.5V Coaxial Ophthalmoscope

• Unique coaxial ophthalmoscope allows easy entry to the eye and shadow-free viewing of the retina
• HPX bulb gives 30% more light than halogen for truer tissue colour
• Dioptre range: +40 to -25

Apertures and Filters:

• Small - Designed specifically for examination of the macular region of the fundus where a larger beam would create excessive pupillary reaction or patient discomfort.
• Intermediate - Permits easier access through and undilated pupil and in peripheral examination.  Particularly useful in paediatric examination.
• Large - Illuminates the largest area of fundus for the best possible general diagnosis through a dilated pupil.
• Fixation-Cross - Projects a graticule onto the retina for assessment of the degree and direction of eccentric fixation.
• Slit - Used primarily to determine retinal elevations and depressions but may also be used to assess anterior chamber depth.
• Red-free - The red free filter is used to examine blood vessels in fine detail.  By filtering out the red light, blood vessels are silhouetted against a dark green background.
