[Morphology of exudate membranes on intraocular lenses]. 1989

J Wolter

The morphological demonstration of exudative depositions on the surface of lens implants can be used as foundation for the understanding of the reactive processes that take place in human eyes in the years following cataract surgery with lens implantation. Clinical cases are used to demonstrate the practically unknown pathology of the different forms of reactive protein membranes together with the typical cellular reactions and the important differences in its fixation to the plastic surfaces. The reactive membrane on silicone lens implants is irregular. Deposition of fibrin, the reactive growth of fibroblasts on lens implants as an early stage of scarring, and the formation of hyaline bodies of different origin on lens implants are also demonstrated.

UI	MeSH Term	Description	Entries
D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens
D007910	Lenses, Intraocular	Artificial implanted lenses.	Implantable Contact Lens,Lens, Intraocular,Contact Lens, Implantable,Intraocular Lens,Intraocular Lenses,Lens, Implantable Contact
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D003459	Crystallins	A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.
