Cavitation rheology of the vitreous: mechanical properties of biological tissue
We demonstrate the importance of measuring the mechanical properties of biological tissue in vivo by quantifying the mechanical properties of bovine vitreous both in its native state and upon removal from the eye. The mechanical properties are determined by the cavitation rheology technique developed in our labs to determine the linear modulus. This technique involves inducing a cavitation even...
متن کاملPrediction of Refractive Outcome of Second Eye with Partial Adjustment of Intraocular Lens Power of the First Eye
Background and Objective: This study aimed at comparing the results of refractive cataract surgery in patients undergoing sequential surgeries in both eyes. Considering the preoperative refraction and final refraction of the first eye, it is possible to correct the refrative result of cataract surgery using the adjustment of the second eye intraocular lens (IOL) power. Materials and Methods: T...
متن کاملHistoanatomical study of the lens and ciliary body in ostrich eye
In the present study, the lenses and ciliary bodies of 20 ostrich eyes were studied macroscopically and microscopically. The histological slides were studied after staining by hematoxylin and eosin, Verhoeff, Van Gieson, and periodic acid-Schiff (PAS). Posterior surface of lens was more convex than its anterior surface. The average lens diameter and thickness were respectively measured as 1.43 ...
متن کاملGrowth of the human eye lens
PURPOSE To analyze human lens growth from the accumulation of wet weight as a function of age. METHODS Wet weights were assembled for over 1,100 human lenses, ranging in age from 6 months prenatal to 99 years postnatal, and were examined using various growth models. Initially, prenatal and postnatal data were examined separately, to determine the growth modes and then all data were fitted to ...
متن کاملDisulfide bond formation in the eye lens.
The disposition and disposal of the -SH groups of the lens during aging and cataractogenesis have been investigated by laser Raman spectroscopy as a noninvasive microprobe in the intact living lens. In this procedure -SH and -S-S- give unique discrete Raman signals (at 2580 and 508 cm-1) that may be used to calculate relative concentrations in a very small volume of the lens. We present evidenc...
