Abstract

PURPOSE. To demonstrate that direct patient experiences
increase understanding of preliminary clinical
procedures in second year optometry students.
A tenet of clinical learning is that experience
examining patients is necessary to further the
understanding of the theory underlying a clinical
procedure. However, there is limited
documentation about how initial patient
encounters reinforce procedures learned in
laboratory settings. The focus of this study was
to quantify how a student's understanding of a
basic clinical procedure changes after
participating in a vision screening exercise. METHOD. 85 second year optometry students (mean
age: 25 years; 41 females, 44 males) performed
portions of the MCT vision screening battery including visual acuity, cover test, and retinoscopy. Each student performed 75 screenings and completed the same pre-screening and post-screening questionnaire. The data were analyzed using the Students t-test.

RESULTS. Direct patient encounters significantly improved
the students'' functional understanding of
refractive conditions (p < 0.05). Student
understanding of the minimum requirements
necessary for passing a static retinoscopy vision
screening test battery increased by 27% for
myopia, 37% for hyperopia, 43% for astigmatism and
35% for anisometropia. Smaller increases in
student understanding of visual acuity occurred by
conducting the test for monocular visual acuity. Concepts of binocular vision were better understood by 12% for exophoria at distance, 11% for esophoria at distance and 16% for esophoria at near.

CONCLUSIONS. These data demonstrate that student understanding of preliminary tests of the visual system improve as a result of participation in vision screening exercises. Students benefit by gaining a deeper understanding of the procedures considered basic to examination of the visual system. Optometric educators gain information on the educational outcomes of laboratory instruction and are able to identify areas in which reinforcement may be required. Administering a questionnaire before and after vision screening is an effective tool to obtain quantitative data on educational outcomes.
