Learning perimetry: the Swedish way

Abstract

Aim: To report experiences from teaching perimetry to ophthalmic nurses during their education at the Karolinska Institutet, Stockholm, Sweden. Subjects and methods: The number of occasions for performing perimetry, both under supervision and independently, during clinical practice were counted and the students' comments analyzed. A computer program for simulation of manual perimetry using the Goldmann apparatus was developed and tested by 20 students. Results: The number of occasions during which students could practise perimetry was variable, depending on the site where the clinical practice period took place, especially regarding manual Goldmann perimetry. The median number of computerized perimetry examinations performed, both under supervision and independent, was approximately 40. The median number Goldmann perimetry examinations performed was two (range zero to five), all under supervision. The students underwent 5-25 training sessions with the computer program. They reported that the program was easy to use, even fun, and that they appreciated the opportunity to practise when and where they wanted. Some student also reported that the simulation training improved confidence and performance in the real perimetry testing situation. Conclusion: Training in planning, performing and evaluating visual field examinations using computerized perimetry appears to be sufficient during current clinical practice periods, but there is a lack of training possibilities for Goldmann Perimetry. A simulation program provides unlimited training opportunities and can be used in parallel to clinical practice.
