Paper Abstract

The ability to image and monitor the metabolic activity of keratocytes is important for the investigation of wound healing and repair mechanisms in the cornea. After laser refractive surgery there is activation of the stromal keratocytes in the human cornea. Two-photon excitation laser scanning microscopy was used to monitor the NAD(P)H levels in keratocytes in the cornea. The autofluorescence was confirmed to be mostly of NAD(P)H origin by treatment with cyanide which caused an increase in the fluorescence by a factor of two. We used a real-time scanning slit confocal microscope to image the distribution of keratocytes in the full thickness of the cornea. This microscope has the ability to image the cellular processes as well as the nuclei of the stromal keratocytes. Noninvasive optical imaging may provide a useful tool to investigate keratocyte activation after laser surgery or wound healing.
