The lens of the eye as a focusing device and its response to stress.

摘要: The continued peripheral growth of the lens, resulting in concentration older tissue toward center, has important optical consequence producing a lens variable refractive index. An approach consisting projection fine laser beams through excised lenses physiological solution been used for vitro study quality. By varying separation incident and/or wavelength characteristics used, properties and relative transparency may be examined. In review provided, these are correlated to suture anatomy, mitochondrial morphology function heat shock proteins. addition, spherical aberration is evaluated as accommodation. This work can highlighted follows: Mammalian direct impact on and, while structure mammalian avian very different, they both show an age-related deterioration focusing ability. distribution appearance mitochondria epithelium superficial fiber cells similar all vertebrates. Lens integrity ability, suggesting correlation between metabolic function. induction cold cataract measured optically cultured enhanced by thermal (heat) this effect prevented inhibiting protein production. Finally, accommodative studied measuring change using model involving intact apparatus.
