The Experimental Study on Ocular Rigidity of Rabbit In Vivo
Ocular rigidity is an important indicator describing the entirety elastic properties of the eyeball, which has a direct correlation with myopia and glaucoma. In this paper, how the intraocular pressures (IOP), central corneal thickness (CCT), and ages influenced ocular rigidity of New Zealand white rabbits was investigated. CCT and basic IOP were measured by the PachyMeter Echograph and Schiote Tonometer respectively. Dynamic relationship between IOP and volume of eye was measured by self-established test system. Our results showed that there was no difference between the ocular rigidity of both eyes in the same group rabbits. The ocular rigidity decreased with the increase of ages, while increased with the IOP. But CCT、initial IOP and Axial Length of the eye in four groups had no significant effects on ocular rigidity.
