Eclipse photodynamic therapy for a presumed peripapillary metastatic tumor.

Purpose: We report a successful use of a modified photodynamic therapy (PDT) termed Eclipse PDT in treating a patient with peripapillary metastatic choroidal tumor.

Methods: Optic disk protection effect was measured with different colored paper disk attached to the reflecting mirror of the laser machine.

Results: Black paper disk was chosen to perform Eclipse PDT because of its maximal blocking effect. A patient with peripapillary metastatic choroidal tumor was treated using this method, and the postoperative outcome was favorable, with improvement in visual acuity and resolution of subretinal fluid.

Conclusion: With the new technique, treatment can be modified according to the lesion's shape and location without damaging the optic disk. Eclipse PDT can further extend the indication of PDT treatment to peripapillary choroidal neovascularization as well as choroidal tumors close to the optic disk.
