COUNT ON EXTENSIVE DIGITAL FILTER

PROCESSING CAPABILITIES.

The CR-2 PLUS AF Digital Retinal Camera produces ultra-high-resolution, 18-megapixel, wide-angle views with excellent color,

detail, and contrast. To further enhance your retinal exam capabilities, the CR-2 PLUS AF has a full set of blue, green, and red

ﬁlters to extract more in-depth information from each image.

The blue ﬁlter provides an excellent view of the retinal nerve ﬁber layer, the internal limiting membrane, retina folds, cysts,

and epiretinal membranes. The green ﬁlter enhances the view of the retinal vasculature and highlights common ﬁndings such

as hemorrhages, drusen, and exudates. The red ﬁlter is useful for pigmentary disturbances, choroidal ruptures, choroidal nevi,

and choroidal melanomas. And the red-free ﬁlter is used for evaluating the Retinal Nerve Fiber Layer (RNFL) and the vascular

structure of the retina as it relates to glaucoma, diabetic retinopathy, and hypertension.
