Area of Science:

  • Ophthalmology
  • Medical Education
  • Simulation Technology

Background:

  • Direct ophthalmoscopy is a crucial diagnostic skill for medical students.
  • Traditional training methods may have limitations in developing proficiency.
  • Ophthalmoscopy simulators offer a potential alternative training modality.

Purpose of the Study:

  • To compare the effectiveness of simulator-based training versus traditional training for medical students in direct ophthalmoscopy.
  • To evaluate the impact of each training method on student skills, efficiency, and interest.

Main Methods:

  • A randomized controlled trial involving first-year medical students.
  • Students received didactic instruction followed by either simulator training or supervised practice with classmates.
  • Ophthalmologist observers and graded answer sheets assessed ophthalmoscopy skills and findings.

Main Results:

  • The simulator group reported significantly longer practice times.
  • Observer-assigned technique scores were higher in the simulator group after adjusting for practice time.
  • The simulator group demonstrated better localization of fundus lesions.

Conclusions:

  • Simulator-based training shows advantages in improving direct ophthalmoscopy technique and lesion localization skills.
  • This training method appears to foster greater student interest and engagement in learning ophthalmoscopy.
  • While direct ophthalmoscopy remains challenging, simulation offers a promising educational tool.
