2.1 Device description
This confocal scanning laser ophthalmoscope is a widefield digital imaging device capable of capturing the area
from the central pole to the far periphery of the retina. The retinal images are captured in an automated, patient
friendly way without scleral depression or contact with the cornea.
The P200T uses red and green lasers to produce a digital, high-resolution image, which is displayed on a PC
monitor screen.
The P200T plus differs from the standard P200T in that it introduces enhanced image quality in both the inferior
and superior areas of the optomap image.
Widefield Confocal Scanning Laser Ophthalmoscope (SLO) fundus imaging is achieved using red and green
lasers. These laser wavelengths penetrate the retinal structures to different depths. Each wavelength provides
information for interpretation and diagnosis.
In autofluorescence mode, the device captures optomap af images using the green laser to illuminate the eye.
This allows an image of the natural fluorescence of the eye to be captured. Fluorescent dye is not introduced
into the patient when performing autofluorescence imaging.
Optos’ technology is designed to operate through a minimum pupil diameter of 2 mm. Although pupil dilation is
NOT required, the decision to dilate is a medical decision to be made by the eyecare professional.
Images are captured on the scan head and then viewed, magnified, annotated and separated into their
components in the review software.
Note
Depending on the features available on your device, you may have a subset of the features described in this
user guide.
2.2 Intended use
The P200T scanning laser ophthalmoscope is intended to be used as a widefield and retinal autofluorescence
imaging ophthalmoscope to aid in the diagnosis and monitoring of diseases or disorders that manifest in the
retina.
