title: Transpupillary thermotherapy in the management of choroidal metastases.
abstract: OBJECTIVE
  To report the authors' experience in the use of infrared diode laser transpupillary thermotherapy in the management of selected posterior choroidal metastatic tumors.
  
  
  METHODS
  Seven eyes of seven patients were treated using 810 nm infrared diode laser. Spot sizes of 0.5 to 3 mm were selected, each lasting 1 minute. When necessary, the treatment was repeated at 8- to 10-week intervals. Disappearance of the tumor was the main outcome measure.
  
  
  RESULTS
  The primary sites of carcinomas were breast, prostate, and lungs. The largest basal diameters of ocular tumors varied between 5 mm and 10 mm and the thickness ranged between 2 mm and 4.5 mm. A mean power of 612 mW was used in one to four treatment sessions. In six eyes the tumors were reduced into flat scars whereas in one case the tumor continued to grow necessitating external beam radiotherapy. In three eyes the visual acuity decreased and in three eyes the vision became better. In one eye the vision was restored after external beam radiotherapy with the disappearance of extensive subretinal fluid. There were no immediate postoperative complications.
  
  
  CONCLUSIONS
  Transpupillary thermotherapy can be a reliable, convenient, and cost-cutting option in the management of small, solitary choroidal metastatic tumors with a thickness of less than 3.5 mm and which have minimal subretinal fluid. Although successful in terms of tumor control, treatment close to the fovea or optic nerve head may cause a permanent decrease in visual acuity.
