Purpose:
To report the case about a patient with conjunctival ocular surface squamous neoplasia who responded well to ocular photodynamic therapy (PDT).
Case:
A 75-year-old man underwent PDT for his biopsy-proven conjunctival squamous cell dysplasia that was extending onto the cornea. Patient received 2 treatments of PDT with verteporfin (6 mg/m(2) body surface area, intravenously) with 2 months apart. The light dose was calculated as 50 J/cm(2). Whole lesion was irradiated 1 min after injection.
Results:
Half of the mass regressed after first PDT. Second PDT resulted in near-complete cure of remaining lesion within 2 weeks. The patient remained stable for the 13 months.
Conclusion:
PDT may be useful in some cases of extensive ocular surface squamous neoplasia that is less than invasive.
