Laser-like precision with the EasyScan

Scanning laser ophthalmoscopy has been around for some years now and allows high contrast imaging of selected layers of the fundus, the depth of the layer highlighted dependent on the wavelength of the incident light. At the Grafton Optical stand at this year’s Optrafair, there was much interest in the EasyScan, an instrument already making inroads in the US and European market and now being launched in the UK. I recently tried out the machine and found the retinal detail revealed in the undilated patient to be most impressive.

EasyScan

The EasyScan is a confocal scanning laser ophthalmoscope (cSLO) that captures retinal images from an undilated patient in a matter of seconds (Figure 1a and 1b). After entering patient data, the machine is aligned with the pupil and then, either using an autofocus option or by manually focusing using the image of the retina on the attached computer screen, captures data from two points of fixation – centrally and nasally, the latter showing an image centred on the disc.
