Comparing the peek retina to fundus camera, direct ophthalmoscope and Volk lens for the viewing of the optic disc

ABSTRACT

Objective: To compare the Peek Retina device with a fundus camera, direct ophthalmoscope and Volk lens. Design and Methodology: The comfort for the patient, efficiency when using the equipment, image quality, time taken, and usability of the equipment were analysed for the four different equipment when the optic disc was viewed. The direct ophthalmoscope, Volk lens and the slit lamp, and a fundus camera were used to view the optic disc in 50 patients at the UWI Optometry Clinic. This four equipment comparison study was done using questionnaires for both the patient and examiner. Results: It was found that peek retina was more comfortable than direct ophthalmoscope and the Volk lens, and it was similar to the fundus camera. Likert scale values showed that the fundus camera was the most efficient and the peek retina the least. The time frame using the fundus camera was the least which was 2.94 minutes compared with using the Volk lens which took the most time of 3.98 minutes. The usability values showed that it was easier to use the fundus camera 1.58 compared to peek retina 2.68, possibly because of the lack of experience with this new device. Conclusion: There was a significant difference among the different devices for the variables examined. The fundus camera was the best at most of the variables and the Peek Retina was the least, while the Volk lens was the most chosen to view the optic disc again due to the clear, stereoscopic and wide view of the back of the eye.
