Abstract Details

Purpose:

Novel devices, such as PEEK Retina, utilise smartphones to capture fundus images, promising to revolutionize the field of Direct Ophthalmoscopy. Glaucoma is a major cause of sight impairment worldwide, with over 60 million people estimated to suffer from glaucoma. Part of the diagnostic process of glaucoma includes optic disc assessment and determining its vertical Cup-to-Disc Ratio (vCDR). This study aims to compare the performances by novice examiners, when using conventional ophthalmoscope and PEEK Retina to determine vCDR values.

Setting:

The study was conducted in the University Hospital of Wales, UK.

Methods:

Medical students received fundoscopy teaching and practical sessions with ophthalmoscopes and 'mannequin heads'. Questionnaires were used to collect information on demographics, pre-test experiences and confidence. Each participant was given an ophthalmoscope and asked to determine the vCDR of the fundus image loaded inside the mannequin head, then grade their level of confidence. This process was then repeated with a PEEK Retina coupled with a smartphone.

Results:

21 students participated in the study. All had prior experience with DO and none have used smartphone-adaptor devices before. Self-rated pre-test confidence was 2.9±0.8. A fundus image with a vCDR of 0.6 was used. With direct ophthalmoscopes, participants reported a vCDR of 0.63±0.16 and the time taken was 26.85±13.03 seconds. Using PEEK Retina, the reported vCDR was 0.59±0.09 and the time taken was 16.10±7.55s. Self-rated confidence ratings were 2.65±1.11 and 3.94±0.62 for the ophthalmoscopes and PEEK Retina, respectively.

Conclusions:

The use of smartphone-based fundoscopy in vCDR measurements as part of glaucoma assessment is of great epidemiological interest, due to the ever-increasing widespread availability of smartphones with high-quality cameras.
