Contact Lens Wearer — Severe Pain and Photophobia, Paracentral Infiltrate with Epithelial...

About This Case

This clinical reasoning case presents a patient with contact lens wearer / severe pain and photophobia / paracentral infiltrate with epithelial defect in a ophthalmology context. Learners work through a structured 10-phase simulation covering initial differential, history-taking, physical examination, labs and imaging, and management planning.

"Bacterial keratitis vs sterile infiltrate — what clinical features determine whether you culture first or start fortified antibiotics empirically?"

How the Simulation Works

1. Read the patient presentation and form your initial differential diagnosis
2. Interview the AI patient to gather history and explore your hypotheses
3. Perform a focused physical examination based on your differential
4. Order appropriate labs and imaging, then interpret the results
5. Revise your diagnosis and develop a management plan
6. Receive personalized teaching feedback from your AI attending, Dr. Patel

What You'll Learn

This case builds skills in systematic clinical reasoning, hypothesis-driven history-taking, appropriate test ordering, and evidence-based management. It is designed for Optometry students and practicing clinicians seeking to sharpen diagnostic thinking in ophthalmology.
