Purpose:
To report a case of orthokeratology lens-related Pseudomonas corneal ulcer in an adult.
Methods:
Case report.
Results:
A 37-year-old man presented with a 1-day history of painful red eye. He was a soft contact lens wearer before he started on nocturnal orthokeratology lens wear of 8 to 10 hours per night 9 months ago. Corneal scraping sent for culture revealed a heavy growth of Pseudomonas aeruginosa. The patient was treated with intensive topical fortified tobramycin and ceftazidime drops. The ulcer healed with a residual paraxial corneal scar. Although his best-corrected visual acuity (BCVA) recovered from finger counting (8/200) at presentation to 20/30, he suffered visual loss from a premorbid BSCVA of 20/15. His contrast sensitivity (Vector Vision CSV 1000 test) performance was also worse than his fellow eye.
Conclusion:
Nocturnal orthokeratology lens wear may be associated with an increased risk of infection.
