Abstract

Purpose : To assess and compare the quality of fundus images of Topcon DRI OCT Triton and 3D OCT-1 Maestro in healthy eyes, glaucomatous eyes, and eyes with retinal disease.

Methods : Three DRI OCT Triton (plus) devices and three 3D OCT-1 Maestro devices were employed. Eligible subjects were randomized to select the study eye and the testing order of the device. 25 healthy eyes, 26 eyes with retinal disease, and 25 glaucoma eyes were studied. All fundus images including macula and optic disc images were sent to the Topcon Reading Center for evaluation of image acceptance and quality grading. Fundus photographs were graded by two masked graders in a randomized fashion. Scoring was based on the quality and clarity of each image. The scores range from 1-5 with 1 being very poor and 5 being excellent according to an image scoring guideline. Analysis of the image quality included the first acceptable photograph from each photograph type. Inter-grader agreement was analyzed using total agreement, which was defined as having the same grading result from both graders. The percentage of total agreement was estimated by photograph type, group and study device with exact 95% confidence interval. A further analysis was performed on image quality grades that differed by 1 point. The images were categorized into two groups based on the grade differences: group 1 includes images where the grades were off by at most one point between the graders; group 2 consists of images that have a grade difference larger than 1 point between graders.

Results : A total of 304 color fundus images were evaluated. 289 (95.1%) and 303 (99.7%) fundus photos received grade 3 or higher by graders 1 and 2, respectively. The total agreement between the two graders ranged between 28% and 68% among the Triton photographs, and between 28% and 64% among the Maestro photographs (Table). The majority of images were in group 1 (n=291 (95.7%); 146 Triton and 145 Maestro). The response rates (i.e., percentage of subjects whose Triton grades were equal to or better than their Maestro grades) ranged between 65.4% and 96% (Table).

Conclusions : Overall, the fundus photo quality was comparable between the two devices. The graders generally agreed on the clinical utility of majority of the fundus images of both the Topcon DRI OCT Triton and 3D OCT-1 Maestro in healthy eyes, glaucomatous eyes, and eyes with retinal disease.
