Binocular Indirect Ophthalmoscope (BIO)

The Welch Allyn 125 BIO is designed to achieve precise binocular viewing and stereopsis easier than ever before. Its observation paths can be adjusted from 49mm to 74mm to handle the widest and narrowest interpupillary distances. There is a small pupil mode enabling examination of patients with pupils as small as 2mm. There is also the option of a diffuser filter which expands the illumination beam and allows enhanced viewing of peripheral areas of the retina. The diffuser filter automatically decreases the intensity of the illumination. This prevents pupil myosis - common in patients with highly sensitive eyes.

There is a choice of power sources, which are sold seperately from the headband.
