Purpose:
The aim of this study was to present our own experience with the use of thermography as a complementary method for the initial diagnosis and differentiation of intraocular tumors, as well as for the evaluation of the efficacy of treatment of intraocular melanomas.
Methods:
The study group comprised 37 patients with intraocular tumors, including 9 with uveal melanoma, 8 with uveal melanoma after I125 brachytherapy, 12 with a focal metastasis to the uvea, and 8 with retinal capillary hemangioblastoma. A FLIR T640 camera was used to capture images in the central point of the cornea, eye area, and orbital cavity area.
Results:
Eyes with uveal melanoma had higher temperature compared with the fellow normal eye of the patient in the range of all measured parameters in the regions of interest. In the group of patients with melanoma after unsuccessful brachytherapy, higher temperature was observed at the central point of the cornea. In patients with tumor regression, all measured parameters were lower in the affected eye. We observed lower tempe-ratures in the range of all tested parameters and areas in eyes with choroidal metastases. Eyes with diagnosed intraocular hemangioblastoma were characterized by higher parameters for the regions of interest versus eyes without this pathology.
Conclusions:
A thermographic examination of the eye can be used as an additional first-line diagnostic tool for the differentiation of intraocular tumors. Thermography can be a helpful tool in monitoring the treatment outcome in patients with intraocular melanoma.
