Abstract
Purpose :
To evaluate the performance of a prototype widefield (90°) slit-scanning ophthalmoscope in undilated imaging of pseudophakic eyes.
Methods :
True Color 90° fundus images were acquired on undilated (nonmydriatic) eyes of pseudophakic subjects using a prototype widefield (WF) slit-scanning ophthalmoscope (SSO) (ZEISS, Dublin, CA) and commercial fundus cameras. Differences in the imaging between the various fundus imagers were evaluated, with a particular focus on the ability to avoid artifacts associated with reflexes from the intraocular lens (IOL).
Results :
Initial True Color images acquired from the prototype WF SSO are presented for an undilated, pseudophakic subject (Figure 1a). The WF images were found to be impervious to IOL artifacts, while careful patient alignment was required to avoid IOL artifacts with the commercial fundus camera (Figure 1b).
Conclusions :
The prototype WF SSO is capable of acquiring true color 90° fundus images in undilated, pseudophakic eyes without the need for careful patient alignment to avoid IOL artifacts, in contrast to the commercial fundus camera. Further improvement in reflex minimization in the prototype is expected, along with comparison to additional commercial fundus imagers.
