Summary

This case was written for a large lecture section that uses powerpoint and personal response systems (clickers) to teach. Students experience a demonstration of the neurological connections to the eye, and examine data showing progressive vision loss in a patient. The vision loss is due to a recessive genetic disease. The implications of that disease are considered. The case uses a powerpoint presentation with embedded clicker questions.

Learning Goals

- To introduce an example of a vision problem and see the effect of genetic disease
- To introduce students to calculating implications of genetic diseases for family members
- To explore the optical nervous system
- To encourage students to humanize patients. Neil is not just presenting a visual field defect, he is a complex person who has responded in some unique ways to his problem, as do all patients

Context for Use

- This case is designed for large introductory biology classes that use clickers (personal response systems) to manage and collect student input. Therefore, the case has clicker questions, marked CQ2 (or whatever number it is), with the correct answer highlighted in bold. Before the powerpoint is used for teaching the case, it is expected that the professor will remove the bolding and format the clicker question for use with the specific hardware / software system that is being used in the course.
