“…New original results obtained using the combination of optical clearing with the known optical visualisation methods, such as laser speckle-contrast imaging [34, 71,75,77,79], OCT [20,29,35,[59][60][61]65,69,80,82], microscopic imaging [23,24,83,84], ultra-microscopy [85][86][87], etc., demonstrated high potentiality of their mutual use not only for getting high-resolution structure and functional tissue images in vitro [72,73,[83][84][85][86][87], but also for optical imaging and diagnostics in vivo [25,34,45,50,59,61,65,68,70,71,[75][76][77][79][80][81]. Table 1 shows the increase of the light penetration depth, caused by clearing agents in some diagnostic methods.…”

Abstract.A review of specific features and methods of optical clearing and related interaction of light with tissues is presented. Physical and molecular mechanisms of immersion, compression, and photodynamic/photothermal optical clearing of some fibrous and cellular tissues are discussed. The possibility of efficient control of the tissue optical properties, particularly, the reduction of light scattering in tissues is demonstrated, which facilitates the increased efficiency of various optical visualisation methods (optical biopsy) used in medical purposes. © 2015 Samara State Aerospace University (SSAU).Keywords: tissue, optical clearing, optical diagnostics, imaging. 1, 404-413 (1997). 5.

“…The main criteria of the choice of OCA for the tissue clearing are: 1) the refractive index of OCA should be close to that of the main tissue scatterers (collagen and elastin fibers or cell membranes); 2) OCA should be hyperosmotic liquid; and 3) biocompatibility 3 . Among the most popular OCAs, there are glycerol, polyethylene glycols, propylene glycol, and glucose [1][2][3][4][5][6][7] . They are biocompatible and do not damage tissues seriously at the short-time action [5][6][7] .…”

Optical clearing of the rat skin under the action of propylene glycol was studied ex vivo. It was found that collimated transmittance of skin samples increased, whereas weight and thickness of the samples decreased during propylene glycol penetration in skin tissue. A mechanism of the optical clearing under the action of propylene glycol is discussed. Diffusion coefficient of propylene glycol in skin tissue ex vivo has been estimated as (1.35±0.95)×10 -7 cm 2 /s with the taking into account of kinetics of both weight and thickness of skin samples. The presented results can be useful for enhancement of many methods of laser therapy and optical diagnostics of skin diseases and localization of subcutaneous neoplasms.

Optical method plays an important role in clinical diagnosis and treatment, but suffers from limited penetration depth of light in turbid tissue. The optical clearing technique can improve the light delivery significantly through immersion of tissues into Optical Clearing Agents (OCAs). However, the barrier function of stratum corneum makes it difficult for optical clearing of skin by topical application of OCAs. Addition of penetration enhancers to OCAs can improve the skin clearing efficacy, but most investigations were performed on in vitro skin. Here, to evaluate the efficacy of this method on in vivo skin, direct observation and measurement of diffuse reflectance spectra were performed after topical application of different mixtures. One OCA, PEG-400, and three penetration enhancers (PEs), Thiazone, Azone and Propylene Glycol (PG), were used. The results indicated that the addition of penetration enhancers could improve the optical clearing efficacy of rat skin in vivo significantly, the dermal blood vessels could be observed directly with PEs.Among the three penetration enhancers, Thiazone induced the largest enhancement of clearing efficacy, and the enhancement induced by PG is the least. This study is very helpful for in vivo application of OCAs to enhance skin optical clearing non-invasively.
