Course Description

Focuses on more advanced diagnostic procedures including electrophysiology tests, direct ophthalmoscopy, advanced color testing, glaucoma techniques, and retinoscopy. Covers the technician's role in assisting in the management of preoperative and post-operative patients. Includes more advanced ophthalmic procedures such as ultrasound, potential acuity meter, direct ophthalmoscopy and contrast sensitivity. Addresses microbiology and specimen collection for the laboratory. Provides an overall review in preparation for national certification examination. Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Perform advanced ophthalmic diagnostic procedures in the clinical setting.
  2. Describe electrophysiology tests in the clinical setting.
  3. Prepare and demonstrate knowledge needed to take the national certification examination.

Outcome Assessment Strategies

The instructor will outline the methods used to evaluate student progress and the criteria for assigning a grade at the beginning of the course. Assessment methods may include written and practical examination and laboratory modules. Evaluation of problem solving skills, team work, attendance, laboratory performance and communication skills may also be included. Extra credit will not be available. All laboratory exercises must be completed satisfactorily to achieve a passing grade. Laboratory modules must be turned in on time. Three late laboratory assignments will result in the lowering of the grade by one letter.
