Furthermore, the stromal expansion of thermally induced lesions in the cornea directly after irradiation was determined within the scope of the laser thermokeratoplasty (LTK). Material and methods: With the experimental scanning OCT system, x-z sections of the anterior eye segment were made with an optical resolution of about 20 mu m axially and 25 mu m laterally. Freshly enucleated, tonicized porcine eyes were used as model eyes. Thermal lesions were applied with a continuously emitting laser diode (lambda=1.86 mu m) and various radiation parameters, Before and after coagulation, the cornea was viewed from limbus to limbus in a central OCT scan and the individual coagulation source was measured, Results: Global and local changes of the thickness of the cornea as well as the distance between cornea and lens were measured with high precision. Thermal lesions in their expansion can be clearly presented and matching well with the histologically stained sections, bur are not as exactly defined at the edges due to the limited optical resolution, as known from histological preparations. Conclusion: With the OCT method quantitative measuring of the anterior eye segment can be performed in vitro and with reduced resolutions also in vivo. Due to the qualitatively good correspondence regarding the dimensions of thermal damage of the cornea with histologically obtained morphometric results,this method can be used for supervision of coagulation directly after LTK as well as for examination of the individual healing process.}, keywords = {optical coherence tomography pachometry laser thermokeratoplasty thermal damage tissue}, ISSN = {0941-293X}, DOI = {DOI 10.1007/s003470050143}, url = {<Go to ISI>://WOS:000071246700003}, year = {1997}, type = {Journal Article} } |

OBJECTIVE: We investigated normal and pathologic structures in human skin in several locations to evaluate the potential application of this technique to dermatology. METHODS: Based on the principle of low-coherence interferometry, cross-sectional images of the human skin can be obtained in vivo with a high spatial resolution of about 15 microns. Within a penetration depth of 0.5 to 1.5 mm, structures of the stratum corneum, the living epidermis, and the papillary dermis can be distinguished. RESULTS: Different layers could be detected that were differentiated by induction of experimental blisters and by comparison with corresponding histologic sections. Furthermore, OCT images of several skin diseases and tumors were obtained. CONCLUSION: OCT is a promising new imaging method for visualization of morphologic changes of superficial layers of the human skin. It may be useful for noninvasive diagnosis of bullous skin diseases, skin tumors, and in vivo investigation of pharmacologic effects.}, keywords = {Adult Anatomy, Cross-Sectional Basement Membrane/pathology Blister/diagnosis/pathology Epidermis/anatomy & histology Evaluation Studies Female Forearm/anatomy & histology Hand/anatomy & histology Humans Hutchinson's Melanotic Freckle/diagnosis/pathology Image Enhancement Interferometry Male Melanoma/diagnosis/pathology Nails/anatomy & histology Optics Skin/*anatomy & histology Skin Diseases/*diagnosis/pathology Skin Diseases, Vesiculobullous/diagnosis/pathology Skin Neoplasms/diagnosis/pathology Tomography/*methods}, url = {http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Citation&list_uids=9418764}, year = {1997}, type = {Journal Article} } |
