Temperature Effect of Silicone Oil at the Anterior Segment

Özet

Purpose: To evaluate the effect of silicone oil tamponade on the central corneal temperature using noncontact infrared thermometer (NCIT) in vitrectomized eyes. Methods: Sixty eyes of 60 patients who underwent pars plana vitrectomy and intraocular silicone oil tamponade were enrolled in this prospective study. Central corneal temperatures were measured by handheld NCIT from the corneal surface and these values were compared with the corneal temperatures of the contralateral eyes of the same subjects. Results: Statistically signifi cant difference was observed between silicone oil fi lled eye and contralateral nonoperated eye (p<0.001). There was a signifi cant correlation between temperature of silicone oil fi lled eye and contralateral eye (p<0.001). Statistically signifi cant negative correlation was observed between postoperative period and temperature of silicone oil fi lled eye (p=0.003). The mean values of temperatures were found to be higher statistically in phakic eyes compared with pseudophakic ones in both silicone oil fi lled and contralateral eye group (p=0.010, p=0.011, respectively). Conclusion: Silicon oil and acrylic and polymethylmethacrylate lenses may affect tissue metabolism because it changes heat conduction. Heat change in tissues can be responsible for complications. Further studies are needed to confi rm our results.
