Abstract
• To investigate the effects of hyperthermia on the proliferation of retinal pigment epithelial cells, in vitro growth of cultured human retinal pigment epithelial cells was studied following heat treatment. Forty-eight hours after plating, heat treatment of 37°C and 41°C to 45°C for 30 or 60 minutes was given to retinal pigment epithelial cells. On days 1, 3, and 7, cell proliferation was evaluated by cell number counting and by DNA synthesis analysis. Hyperthermia gave statistically significant suppression of cell growth above 43°C heat treatment and absolute cell number reduction above 44°C on the seventh day. Deoxyribonucleic acid synthesis was significantly suppressed with 43°C for 60 minutes or above 44°C heat treatment. Hyperthermia may be a potential new therapy for proliferative vitreoretinopathy.
