Thermography is the method of noninvasive registration of visible image of the own infrared radiation of the human body surface by special devices. The physiological basis of its application in medical diagnostics is the amplification of infrared radiation intensity from pathologic spots that is connected with the enhancement of blood supply and metabolism. Purpose . To study the possibilities of thermography for functional bleb status assessment, for early diagnostics of bleb scarring processes and for definition of needling indications. Patients and methods . There were executed 32 thermography (32 patients and eyes) of blebs in 7 days after minimally invasive sinustrabeculectomy. Authors used thermal imaging Тesto 875-2i with SuperResolution technology and telephoto lens 9°×7°. The bleb area and temperature were studied With IRSoft and Universal Desktop Ruler programs. Intraocular pressure (corneal compensated) (IOPcc) was measured with Ocular Response Analyzer®, ORA. Conclusion . The study has shown the direct correlation dependence between bleb functional activity and its thermographic characteristics (area and temperature).
