Accuracy of vertical cup-to-disc ratio discrimination among clinical optometry trainees with different years of clinical experience.

ABSTRACT:

Purpose

Accurate evaluation of the cup-to-disc ratio is crucial for optometrists and may be influenced by their clinical experience. The study's objective was to compare the thresholds for discriminating vertical cup-to-disc ratio (VCDR) between years 2, 3, and 4 clinical optometry trainees.

Methods

One hundred fundus photos with various VCDR sizes were selected from a clinic database. The median VCDR (0.43) photo was assigned as the standard, while the other 99 were assigned as the test photos. The participant's task was to discriminate using a 2-alternate-forced-choice paradigm whether the test photos' VCDR were larger or smaller than the standard VCDR. Data were fit with a Weibull function, and three discrimination thresholds were determined: the point of subjective equal
