Summary
Eclipse photodynamic therapy (PDT) successfully treated a patient with a peripapillary choroidal tumor. This modified PDT technique protects the optic disk, improving outcomes for tumors near this critical structure.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Peripapillary choroidal tumors pose treatment challenges due to proximity to the optic disk.
- Standard photodynamic therapy (PDT) may risk optic nerve damage in these cases.
Purpose of the Study:
- To report the successful application of a modified PDT technique, termed Eclipse PDT, for treating a peripapillary metastatic choroidal tumor.
- To evaluate the efficacy and safety of Eclipse PDT in protecting the optic disk.
Main Methods:
- Developed and tested a modified PDT technique (Eclipse PDT) incorporating optic disk protection.
- Evaluated optic disk protection using different colored paper disks attached to the laser machine's reflecting mirror.
- Selected black paper for maximal blocking effect.
Main Results:
- Black paper demonstrated maximal optic disk blocking effect in the modified PDT setup.
- A patient with peripapillary metastatic choroidal tumor treated with Eclipse PDT showed favorable outcomes.
- Postoperative results included improved visual acuity and resolution of subretinal fluid.
Conclusions:
- Eclipse PDT allows for tailored treatment based on lesion characteristics without compromising the optic disk.
- This technique expands PDT indications to include peripapillary choroidal neovascularization and tumors near the optic disk.
