Title: A 34 Year-old Woman
with Visual Loss and Eye Pain
• Chief Complaint
– 34 year-old Caucasian woman with two days of
decreased vision in her right eye and throbbing
pain behind her eye
History of Present Illness
– For several weeks she states that she has “not
felt quite right.” 3 days ago she was seen in the
Emergency Department of a local community
hospital. The patient was told that her physical
exam including pelvic exam were “normal” and
some lab tests were sent. She was discharged
and told to follow up with her primary medical
doctor. She sees a doctor at a community
health center, and has an appointment for next
week.

with coughing or straining, but doesn’t change
with movement of her eyes. She denies any
symptoms in her left eye.

The Answer:
Ocular Syphilis
My Predictions…
• Diagnostic test?
– Blood/CSF
• RPR/VDRL/FTA-ABS/MHA-TP
• HIV testing
– 41% chance of being HIV(+)
• Treated per neurosyphilis protocols
– IV penicillin G
• 12 to 24 million units qd X 6-21 days
Our Patient’s Ocular Future?
85% chance of return to near normal vision
Our Patient
Normal
Thank You for This Opportunity
Moderator:
Dr. Amanda Young
The Final Diagnosis:
Ocular Syphilis
The Final Diagnosis:
• Diagnostic test: (+) VDRL
• Clinical course
– Two weeks of IV penicillin
• Outcome
– Almost complete recovery at 6
month follow up
