Course Description

Introduces the common forms of ophthalmic imaging, OCT (Optical Coherence Tomography) ophthalmic photography (Fundus and Slit lamp) and FA (fluorescein angiography), FAF (Fundus auto fluorescence). Includes other types of imaging used in ophthalmology (CT, MRI, CCT, HRT, Ultrasound, and External Photography). Audit available.

Addendum to Course Description

Discusses the differences between mode of fundus imaging with Scanning Laser Ophthalmoscope, Digital photography, and film based photography.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Apply knowledge of ophthalmic imaging to the use of diagnostic laser testing equipment in the clinic setting.
  2. Use photographic principles to support clinical training and use of ophthalmic imaging.
  3. Use imaging standardization practices that apply to different ocular diseases.
  4. Determine the correct protocol before and during an Optical Coherence Tomography (OCT) exam applicable to different ocular diseases in an ophthalmology clinic.

Course Activities and Design

This course will be presented by means of lecture/discussion, audio/visual presentations, handouts and demonstrations. Guest speakers and field trips may be used to enhance mastery of course goals and student learning.

Outcome Assessment Strategies

At the beginning of the course the instructor will detail the methods used to evaluate student progress and criteria for assigning a course grade. These may include examinations, quizzes, homework assignments, research papers, and student participation during class sessions.
